Introduction

In recent years, analysts have questioned whether the United States has reached a tipping point in its global economic relevance, after decades of dominance. This concern centers on the possibility of a rapid decline in U.S. influence over the world economy, driven by many years of protectionist, isolationist, and inward-focused policies. Trade wars, tariff barriers, retreat from free trade agreements, and a focus on “America First” have arguably eroded U.S. leadership in global trade and investment. This report examines expert opinions, economic indicators, and trade patterns to determine if such an inflection point has been reached or is imminent. Key evidence—from the U.S. share of world GDP and trade to foreign direct investment (FDI) flows and shifting geopolitical alliances—is presented alongside historical parallels. The goal is to assess whether the United States is truly at a juncture beyond which its global economic influence enters a steep decline or if it can yet reverse course.

Background: From Post-War Leadership to Inward Turn

For much of the post-World War II era, the U.S. championed liberal trade and led the global economic order. Institutions like the GATT/WTO and trade pacts under U.S. guidance helped cement its dominance. In recent years, however, U.S. policy has become more inward-focused. Protectionist measures have increased markedly, especially since 2017. For example, President Donald Trump withdrew the U.S. from the Trans-Pacific Partnership (TPP) trade deal immediately upon taking office and imposed broad tariffs – including steel and aluminum duties on allies (justified on national security grounds) (Is America becoming protectionist? | United States Studies Centre). He also launched a tariff war with China, raising import taxes on roughly $335 billion of Chinese goods; by early 2020 U.S. tariffs on Chinese imports averaged about 19%, over six times higher than in January 2018 before the trade war (US-China Trade War Tariffs: An Up-to-Date Chart | PIIE). China retaliated in kind, driving its tariffs on U.S. goods up from 8% to over 21% (US-China Trade War Tariffs: An Up-to-Date Chart | PIIE).

President Joe Biden, while shifting tone, continued many Trump-era policies. Biden kept in place most of the tariffs on China and steel, and pointedly stayed out of the revived CPTPP (Comprehensive and Progressive TPP) (Is America becoming protectionist? | United States Studies Centre). His administration emphasized domestic investment via the Inflation Reduction Act and CHIPS Act, which include “Buy American” provisions and subsidies for U.S.-based manufacturing (Is America becoming protectionist? | United States Studies Centre). Both the Trump and Biden administrations also pulled back from the WTO’s processes – for instance, blocking its appellate body – signaling reduced U.S. commitment to multilateral trade rules (Is America becoming protectionist? | United States Studies Centre). Even Biden’s signature Asia engagement initiative, the Indo-Pacific Economic Framework (IPEF), pointedly avoids market-access commitments, due to domestic resistance to trade liberalization (Is America becoming protectionist? | United States Studies Centre).

The cumulative effect of these trends is a more insular U.S. stance. By prioritizing tariffs and local industry protection, the U.S. has stepped back from its traditional role as architect of global trade expansion. This inward turn was meant to shore up domestic jobs and industries. However, it has also coincided with other economies – notably China and various regional blocs – moving to fill the void. U.S. allies and partners have noticed the change: America’s retreat from big trade pacts and its aggressive use of sanctions/tariffs have prompted others to deepen ties among themselves (China trade surge poses challenge for Trump’s South America influence | Reuters) (China trade surge poses challenge for Trump’s South America influence | Reuters). As one former U.S. State Department official warned, “Unless the United States meaningfully prioritizes regional economic policy in a new and more effective way, the region will continue to tilt toward Chinese interests.” (In South America, Trump already losing a trade battle with China | Reuters) In short, many years of U.S. policy “looking inward” may be undermining the very global economic leadership that underpinned American power.

Key Economic Indicators of U.S. Global Standing

*(2000 export share is approximate; China’s was only ~4% in 2000, for context.)

As the table shows, the U.S. share of world GDP has declined from roughly 30% in 2000 to about 26% in 2023, a significant drop in two decades ( US GDP as % of World GDP Yearly Analysis: World Development Indicators | YCharts ) ( US GDP as % of World GDP Yearly Analysis: World Development Indicators | YCharts ). The erosion was especially sharp in the 2000s (coinciding with rapid growth in China and other emerging markets), though the U.S. share stabilized in the 2020s due to a strong recovery and slower global growth. Still, in purchasing-power-parity (PPP) terms – which reflect real economy size – the U.S. now accounts for only ~15% of global output, well behind China’s ~19% (World Economic Outlook (October 2024) – GDP based on PPP …) (Economy of the United States – Wikipedia). Simply put, the U.S. no longer towers over the world economy as it did in the late 20th century.

In global trade, U.S. relative influence has diminished even more visibly. In 2000, the U.S. was the world’s largest goods exporter; today it ranks second, and not a close second. In 2022, China was the top merchandise exporter with about 14% of global export share, while the U.S. accounted for just 8% ($31 TRILLION: Goods and services trade jumps 13%). (Germany was third at ~7%.) The U.S. is still the single largest importer, reflecting its huge consumer market, but China’s market has become equally indispensable for exporters worldwide. According to IMF trade data, around 70% of countries now trade more with China than with the U.S. (China versus America on global trade – Lowy Institute) (China versus America on global trade – Lowy Institute). In 2023, China was the largest trading partner for 60 nations, nearly double the number for which the U.S. was number one (33 nations) (China versus America on global trade – Lowy Institute). This marks a dramatic reversal from two decades ago; as recently as 2001, more than 80% of economies traded more with America than with China (China versus America on global trade – Lowy Institute). The “days of America’s trade dominance have passed,” as one analysis bluntly concluded (China Is the Top Trading Partner to More Than 120 Countries | Wilson Center).

A clear illustration is in emerging markets: China has displaced the U.S. as the primary trading partner across the Global South. For instance, China is now the top trade partner for major economies like Brazil, South Africa, and Saudi Arabia (China Is the Top Trading Partner to More Than 120 Countries | Wilson Center). Even in Latin America – traditionally seen as the U.S.’ backyard – Beijing’s commercial presence is eclipsing Washington’s. **South America’s exports to China have more than doubled in the past decade, while exports to the U.S. barely inched up】 (China trade surge poses challenge for Trump’s South America influence | Reuters). China overtook the U.S. as Peru’s largest trade partner in 2015 and has since widened that lead; by 2023 China was trading $16.3 billion more with Peru than the U.S. – a “stark reversal” of the trade patterns just ten years prior (In South America, Trump already losing a trade battle with China | Reuters). This shift “eroded Washington’s regional political clout, a trend that widened under Trump’s ‘America First’ inward turn … and again under Biden,” Reuters reported (In South America, Trump already losing a trade battle with China | Reuters). In Africa, a similar story unfolded: China-Africa trade hit a record $262 billion in 2023 (Data: China-Africa Trade — China Africa Research Initiative ), making China by far Africa’s largest bilateral commercial partner. The U.S., by contrast, trades much less with Africa and has seen its share of African imports of key goods (like machinery) fall behind China’s. These trade realignments underscore how other economies – especially China – have capitalized on America’s relative retreat to strengthen their own ties in the global marketplace.

In terms of foreign direct investment, the U.S. remains a leading destination but faces intensifying competition. In 2000, the U.S. attracted around one-third of global FDI stock; today it holds about 26% of the world’s inward FDI stock ( Foreign Direct Investment in the United States 2024 – GBA ). Notably, U.S. share plunged to just 20% in 2013 but has rebounded since ( Foreign Direct Investment in the United States 2024 – GBA ), implying that global investors still view the U.S. as attractive (particularly in high-tech and advanced sectors, where recent onshoring policies drew investment). Even so, developing economies collectively now account for 32% of global FDI stock, far above the U.S. share ( Foreign Direct Investment in the United States 2024 – GBA ). China alone jumped from virtually nothing two decades ago to about 7% of global inward FDI stock by 2023 ( Foreign Direct Investment in the United States 2024 – GBA ). In other words, while the U.S. is still the single largest magnet for investment, most foreign investment is flowing elsewhere (chiefly to emerging Asia). A U.S. business advocacy report warns that America “faces stiff global competition for investment dollars”, with its share of world FDI significantly lower than it was in the early 2000s ( Foreign Direct Investment in the United States 2024 – GBA ). The U.S. also remains a top source of outbound FDI, but China’s outward investment (via Belt and Road infrastructure projects, overseas acquisitions, etc.) has surged, enhancing China’s economic influence abroad in ways the U.S. must now compete with.

Taken together, these indicators – GDP, trade, and investment – paint a picture of relative U.S. decline (gradual, but measurable) in the global economy. The United States is still a huge player, but it is no longer the undisputed hub of all economic roads. Other centers of gravity, especially China, have risen in parallel, and by some metrics even surpassed the U.S. The next sections explore how policy choices and geopolitical realignments have accelerated this trend, and whether we have reached a true inflection point.

Geopolitical Realignments and Trade Patterns

One of the clearest signs of an inflection point is the changing geopolitical alignment of trade. As U.S. policy turned inward, China expanded its global economic outreach, especially in the Global South. Beijing’s Belt and Road Initiative (BRI) has poured hundreds of billions into infrastructure and tied over 140 countries closer to China’s economy. Meanwhile, regional trade agreements have flourished without U.S. involvement. The most notable is the Regional Comprehensive Economic Partnership (RCEP), a 15-nation Asia-Pacific trade pact (including China, Japan, South Korea, ASEAN, etc.) that formed the world’s largest trading bloc – about 30% of global GDP – with the United States conspicuously absent (RCEP, the The World’s Largest Trade Agreement, Doesn’t Include the United States). RCEP’s formation in 2020 was “spearheaded by China” and “accelerated by the Trump administration’s protectionist trade policy,” according to Foreign Policy analyses (RCEP, the The World’s Largest Trade Agreement, Doesn’t Include the United States). In effect, East Asia moved on to deepen integration, reducing tariffs and setting common rules, even as the U.S. withdrew from the region’s previous U.S.-led trade initiative (the TPP). Similarly, the Comprehensive and Progressive Agreement for TPP (CPTPP) now links 11 Pacific Rim economies (including U.S. allies like Japan, Canada, and Australia) in a high-standards trade zone – again without U.S. membership. These new pacts mean billions in trade and investment are governed by frameworks the U.S. doesn’t shape, arguably diluting U.S. influence over time.

The rise of China as the primary trade partner for most of the world has strategic implications. Countries that once depended on access to U.S. markets or American-led finance can now turn to China (or regional groupings) as alternatives. For example, when Washington imposed punitive tariffs or sanctions, some nations found “less risky alternatives like China, Europe or the BRICS” to reduce reliance on the U.S. (China trade surge poses challenge for Trump’s South America influence | Reuters). A senior Brazilian diplomat noted in 2025 that Brazil’s economy “was not dependent on the United States,” pointing to its far larger trade with China than with the U.S. (China trade surge poses challenge for Trump’s South America influence | Reuters). In Latin America, Chinese firms invest heavily in energy, mining, ports, and telecom – sectors where U.S. companies once led. In Africa, China offers loans and projects many African nations didn’t get from Western lenders. This pragmatic engagement by China has earned it goodwill (even as it pursues its own interests), while U.S. influence wanes. “The Chinese come here to do business,” said one Latin American official, contrasting Beijing’s steady economic outreach with what he characterized as years of U.S. “neglect” punctuated only by pressure and threats (China trade surge poses challenge for Trump’s South America influence | Reuters).

Even some traditional U.S. allies are hedging. In the Middle East, Gulf states like Saudi Arabia increasingly trade oil for Chinese goods and coordinate investment with Beijing (for instance, Saudi Arabia and the UAE joined the BRICS grouping in 2023). The European Union, while aligned with the U.S. politically, counts China as its largest external trade partner (China Is the Top Trading Partner to More Than 120 Countries | Wilson Center) and has been cautious in decoupling its economy. This does not mean U.S. alliances are dissolving – but economically, a multipolar pattern is evident. Washington’s ability to unilaterally set the terms of global commerce is diminishing. Where once U.S. trade or financial sanctions could isolate a country, today that country may still find support from China, Russia, or others operating outside the U.S.-led system. For example, U.S. tariffs on Chinese goods have led Beijing to deepen trade with other partners (ASEAN is now China’s #1 trading bloc). And when Russian banks were sanctioned by the West, Moscow pivoted to China and India to sell its energy, partially blunting U.S. leverage. These realignments suggest a less U.S.-centric global economy – a hallmark of an inflection toward a more multipolar economic order.

Crucially, expert observers see these trends as a consequence of U.S. policy choices. Former WTO chief economist Anne O. Krueger argues that America’s embrace of unilateral tariffs and sanctions has “at best” been ineffective and at worst “counterproductive,” raising costs for Americans without achieving strategic goals (America’s Protectionist Policies Are Backfiring by Anne O. Krueger – Project Syndicate). Instead of weakening adversaries like China or Russia, such measures sometimes push other countries closer together (for instance, driving U.S. trade partners to arrange non-dollar payment systems or alternative supply chains). Michael J. Green, a former U.S. official, notes that both U.S. political parties have turned somewhat skeptical on free trade, creating a vacuum in economic leadership: “The American retreat from the WTO has left China in a stronger position to try to rewrite the rules in ways that disadvantage American interests. The Trump and Biden administrations have been foolish to cede that field of competition.” (Is America becoming protectionist? | United States Studies Centre) In Asia, the Sydney-based Lowy Institute’s Asia Power Index found that U.S. economic influence in the region declined from 2018 to 2022, coinciding with the U.S. withdrawal from trade agreements and China’s expanding trade links (Is America becoming protectionist? | United States Studies Centre). In short, while China and others proactively court trade relationships and champion new deals, U.S. policies like tariffs or the absence from major pacts have arguably undercut America’s long-run position.

Policy Impacts: Tariffs, Trade Pacts, and Self-Inflicted Wounds

To gauge if a true inflection point has been reached, one must examine the impact of U.S. policy decisions on economic outcomes. Several years on, what have inward-focused policies achieved?

• Trade Volumes and Supply Chains: The U.S.-China tariff war did reduce bilateral trade somewhat, but it did not bring manufacturing back en masse nor cripple China’s trade. Instead, trade flows rerouted. By 2023, China’s share of U.S. imports had fallen (U.S. imports from China were ~13% of total, down from ~21% in 2017), as companies shifted sourcing to countries like Vietnam, Mexico, and India. However, America’s overall trade deficit remained large, just split among more partners. And China compensated by trading more with Asia, Africa, and Latin America. Notably, China–South America trade boomed while U.S.–South America trade stagnated (China trade surge poses challenge for Trump’s South America influence | Reuters). In high-tech sectors, U.S. export controls (e.g. on semiconductors) have started a partial decoupling, but allies have not entirely followed suit, and China is investing to become self-sufficient in critical technologies. Thus, protectionism achieved limited reshoring for the U.S., while prompting others to diversify away from U.S.-dependent supply chains.
• GDP and Investment: Tariffs act like a tax on consumers and producers. American manufacturers faced higher input costs, and farmers lost markets due to retaliatory tariffs. The OECD and IMF lowered U.S. growth forecasts during the trade war, citing trade barriers (10 Trends That Will Shape the Global Economy Over the Next Decade). One study estimated a worst-case scenario of comprehensive U.S. protectionism could cut U.S. GDP by 2.3% (over $400 billion) in the long term (US economic isolation hurts the global economy – and the US itself). Even targeted measures like reimposing NAFTA tariffs were found to harm U.S. income modestly (US economic isolation hurts the global economy – and the US itself). While the actual economic hit from the 2018–19 tariffs was smaller than these extreme scenarios (in part due to a strong pre-pandemic economy), many analyses conclude the tariffs depressed U.S. job growth in affected industries and raised consumer prices (America’s Protectionist Policies Are Backfiring by Anne O. Krueger – Project Syndicate). Meanwhile, countries not embroiled in the tariffs often benefited by capturing diverted trade (US economic isolation hurts the global economy – and the US itself). For instance, German exports to the U.S. rose when NAFTA trade was disrupted (US economic isolation hurts the global economy – and the US itself). On the investment front, U.S. FDI inflows actually surged in 2021–22 (post-pandemic) as firms sought stable havens, but much of this was in response to stimulus and market size, not tariffs. The long-run risk is that if the U.S. is seen as unpredictable or hostile to trade, investors may favor building capacity in more open markets (like the EU or Asia) to serve global demand. Thus far, the U.S. remains a premier investment destination, but the trend of emerging economies attracting more FDI (32% of global stock, as noted) signals that capital is finding opportunities outside the U.S. at a faster rate ( Foreign Direct Investment in the United States 2024 – GBA ).
• Isolation from Trade Pacts: Perhaps the most enduring impact of recent U.S. policy is missing out on new trade architectures. The U.S.’ absence from RCEP and CPTPP means it has no seat at the table in shaping rules for the Asia-Pacific – the world’s most economically dynamic region. This has strategic costs. For example, digital trade standards, e-commerce rules, and tariff schedules are being set in Asia without U.S. input, potentially disadvantaging U.S. companies. In contrast, China has applied to join the CPTPP (though not yet admitted) and is deeply integrated in RCEP, giving it a say in Asia’s economic governance. Moreover, U.S. exporters don’t enjoy the tariff reductions that CPTPP members grant each other, making American goods relatively less competitive in those markets over time. A concrete case: Australia and Japan now have freer trade with Canada or Vietnam (via CPTPP) than the U.S. does, which can divert trade and investment. The U.S. attempt to form an alternate framework (IPEF) without market access has so far yielded modest results, partly because Asian partners also signed onto RCEP/CPTPP for the real trade benefits. Overall, stepping back from regional trade pacts has reduced U.S. economic influence and credibility – partners are less likely to align with Washington’s economic agenda if the U.S. itself won’t provide greater access or leadership.

In summary, protectionist and go-it-alone measures have largely backfired or under-delivered on their promises. They have neither decisively boosted U.S. manufacturing nor stopped China’s rise; instead, they taxed U.S. consumers and alienated allies. “What’s going to hurt the U.S. is the U.S.,” quipped one trade expert about American protectionism reshaping the world economy (The future of global trade: ‘What’s going to hurt the U.S. is the U.S.’). This sense that America’s own choices could precipitate its decline is at the heart of the inflection point debate.

Are We at the Tipping Point?

Given the evidence – shrinking U.S. shares of global output and trade, the proliferation of non-U.S.-centric economic blocs, and self-inflicted policy wounds – is the United States now at an inflection point of rapid decline in global economic relevance? Opinions vary among experts, but a few common threads emerge:

• Many analysts believe a tipping point is imminent (or just passed). They point to the confluence of events in the late 2010s and early 2020s – the U.S. trade war, the pandemic (which revealed supply chain vulnerabilities), China’s Belt and Road and trade diplomacy successes, and now the Ukraine war pushing Russia and China closer – as creating a critical juncture. Ambassador Mark Green wrote that the trendlines leave little doubt: “the days of America’s trade dominance have passed” (China Is the Top Trading Partner to More Than 120 Countries | Wilson Center). Similarly, the Lowy Institute’s data-driven index now ranks the U.S. behind China in economic influence in Asia (Is America becoming protectionist? | United States Studies Centre). To these observers, the world has already pivoted to a multipolar economy, with the U.S. just one of several heavyweight players. If the U.S. continues on its current course (eschewing trade leadership and focusing inward), they argue, its relative decline will accelerate. Markets and alliances can reach a tipping point where perceptions shift: once countries and companies view the U.S. as less reliable or less central, behaviors change rapidly (diverting investment, pricing in geopolitical risk, etc.), creating a self-reinforcing downward spiral in influence. Some fear that moment is at hand.
• Others contend the U.S. still has time and strengths on its side, even if its margin of dominance is eroding. The U.S. economy is currently quite robust (unemployment at historic lows, a tech innovation boom in AI and clean energy, etc.), and it remains the world’s largest economy in nominal terms by a wide gap (GDP nearly $7–10 trillion greater than China’s, at market exchange rates). The U.S. dollar is still involved in 88% of global forex transactions and accounts for ~58% of global foreign reserves – a monetary influence that China cannot yet match (De-dollarization: The end of dollar dominance? – J.P. Morgan). Moreover, the U.S. retains unparalleled soft power in higher education, research, and culture, and it leads in critical technologies (software, aerospace, biomedical). These experts argue that while the U.S. share of manufacturing or trade has fallen, the quality and value-added of U.S. economic engagement (high-end services, investment, finance) remain very high. For example, the U.S. is the largest exporter of services (nearly $1 trillion in 2022) including financial and digital services that embed the U.S. in global commerce in less visible ways (Countries & Regions | United States Trade Representative). They also note that U.S. inward FDI reached record levels over the past decade – “much of the world is coming to America,” as Michael Green observes, attracted by the U.S. market and innovation climate (Is America becoming protectionist? | United States Studies Centre). From this perspective, the U.S. is evolving its global economic role rather than simply hemorrhaging it. The economy is shifting toward areas where the U.S. is still highly competitive (like semiconductors, entertainment, advanced manufacturing via robotics, etc.), even as it cedes low-end production to others. Thus, a gradual relative decline need not equate to a sudden collapse or irrelevance; the U.S. could remain the preeminent node in a networked global economy if it plays to its strengths.
• Historical parallels provide both warnings and hope. One frequently cited parallel is Britain in the late 19th and early 20th centuries. The British Empire was once the world’s workshop and financial center, but as Germany and the U.S. industrialized, Britain’s share of manufacturing and trade fell. Britain’s turn to imperial protection (tariff preferences within its empire) in the 1930s is often seen as an accelerant of its economic decline, as it failed to keep pace with more dynamic economies and lost its free-trade leadership. The U.S. now risks a similar “British dilemma”: whether to double down on a shrinking sphere or reinvent its global engagement. Another parallel is the interwar United States – after World War I, the U.S. retreated into isolationism (high tariffs like Smoot-Hawley in 1930, immigration restrictions, avoiding the League of Nations). That vacuum in global economic leadership contributed to a breakdown in international trade and finance during the Great Depression (Is America becoming protectionist? | United States Studies Centre). It took the catastrophe of World War II for the U.S. to realize that re-engaging and leading (through Bretton Woods institutions, the Marshall Plan, GATT, etc.) was essential to both global stability and U.S. prosperity. These lessons suggest that a retreat behind economic walls can indeed mark a turning point downward, but they also show that course corrections are possible. The U.S. reinvented its global role in 1945; Britain found new life by embracing European and global markets after Suez.

Considering all of the above, has the inflection point been reached? There is strong evidence that we are at least very close. The U.S. no longer calls the shots in global trade as it did for decades – a reality that seemed to crystallize in the late 2010s. The combination of America-first protectionism and the rise of China-led alternatives has, as one report put it, “pushed the West to the margins” in some trade arenas (RCEP, the The World’s Largest Trade Agreement, Doesn’t Include the United States). If one defines an inflection point as the moment when incremental change turns into a decisive, self-perpetuating shift, the period around 2018–2022 may qualify: U.S. trade policy turned sharply inward, China seized the mantle of trade leadership (signing RCEP, courting partners), and now even allies like the EU and Japan are pursuing strategic autonomy in economic matters, no longer relying wholly on U.S. leadership.

However, the magnitude and rapidity of any U.S. decline are still under debate. The U.S. could yet arrest or slow the decline by changing policies – for instance, by rejoining or initiating trade agreements, working with allies to present a united economic front, and investing in the competitiveness of its industries without alienating partners. The inflection point is not necessarily a cliff. It can be a turning onto a gentler downward slope if corrective action is taken. But if current trends continue unchecked, the slope could steepen. As Congressman Raja Krishnamoorthi warned in context of Latin America, the U.S. must be careful not to become “the bully in the neighborhood” because “you know what happens to bullies: people stand up to [them].” (China trade surge poses challenge for Trump’s South America influence | Reuters) His point underscores that U.S. coercive economic tactics can provoke a backlash that hastens the loss of U.S. influence – precisely the dynamic at issue.

Conclusion

The United States stands at a crossroads in its global economic role. Years of inward-focused policies and disengagement from multilateral trade have coincided with a surge in alternative economic powers and arrangements. America’s share of the world economy and trade has slid, and competitors have leveraged every U.S. misstep to bolster their own position. By many measures, we appear to be at or near an inflection point: the U.S. is no longer the unrivaled center of the global economy, and if present trends continue, a more rapid relative decline in influence is plausible. Economic indicators (from GDP and trade shares to FDI flows) all point to a relative waning of U.S. dominance ( US GDP as % of World GDP Yearly Analysis: World Development Indicators | YCharts ) ($31 TRILLION: Goods and services trade jumps 13%), while geopolitical shifts (China as the top trade partner for most countries, new trade blocs sans America) illustrate a world less tied to U.S. leadership (China versus America on global trade – Lowy Institute) (RCEP, the The World’s Largest Trade Agreement, Doesn’t Include the United States). Expert assessments warn that American protectionism and unilateralism have been self-defeating, undermining U.S. strategic goals and ceding ground to others (America’s Protectionist Policies Are Backfiring by Anne O. Krueger – Project Syndicate) (In South America, Trump already losing a trade battle with China | Reuters). Historical precedents reinforce that turning inward often marks the beginning of a great power’s economic decline.

Yet, it is not foreordained that the U.S. will suffer a rapid or irreversible fall in global economic relevance. The U.S. retains formidable advantages – an immense consumer market, innovation hubs, the world’s reserve currency, and a network of allies – that can be leveraged to maintain a strong global position. The question is whether the U.S. will recognize this pivotal moment and adjust course. Re-engaging with the world economy through updated trade agreements, investing in competitiveness without resorting to beggar-thy-neighbor policies, and working with allies to set global standards could all help the U.S. bend the curve of decline. In effect, the U.S. can choose whether this inflection point leads to a soft landing into a shared leadership role in a multipolar economy, or a hard fall where it rapidly loses clout.

In conclusion, the evidence suggests the tipping point is real and near. If the United States wishes to arrest a rapid downward trajectory, it will need to pivot away from isolationism and back toward the kind of international economic engagement that originally underwrote its prosperity and power. As one expert succinctly put it, “Reassert U.S. leadership by identifying U.S. global economic and trade interests… [America] has been foolish to cede that field.” (Is America becoming protectionist? | United States Studies Centre) The coming years will reveal whether the U.S. can reinvent its global economic strategy or whether historians will look back on the late 2010s/2020s as the moment when U.S. economic primacy hit its inflection point and entered a lasting decline.
