Renewed US-China trade tensions rattle markets

Trade tensions between the United States and China have escalated sharply after President Donald Trump announced plans to impose an additional 100 percent tariff on Chinese goods and to tighten export controls on critical software and other products. These measures, set to take effect by November 1 or earlier if China fails to back down, mark a significant escalation in what many observers fear could reignite a full-scale trade war between the world’s two largest economies.

The move came in response to Beijing’s new export restrictions on rare earths and critical minerals—materials essential for producing electronics, electric vehicles, and military equipment. Under China’s new rules, foreign companies must now seek government approval to export products containing even small quantities of these materials. This policy mirrors earlier US restrictions on technology exports to China and is widely seen as Beijing’s attempt to gain leverage ahead of a potential meeting between Trump and President Xi Jinping later this month.

Trump reacted by threatening to cancel the meeting, accusing China of taking an “extraordinarily aggressive” stance on trade. While he later softened his tone, suggesting the summit could still occur, markets had already reacted sharply to the uncertainty. US equities saw their biggest one-day drop in months, with the S&P 500 down 2.7 percent and the Nasdaq falling 3.6 percent. Investors fled to safer assets: yields on two-year Treasury notes dropped to a three-week low, and the US dollar weakened against major currencies.

At the core of this confrontation is control over global supply chains. China dominates the production of rare earth elements, which are indispensable to modern technology. By curbing exports, Beijing effectively weaponizes its market dominance, much as the US has used its control over advanced semiconductor technology to pressure China. Trump’s response, proposing broad export restrictions and new tariffs, aims to counter what he sees as an attempt by China to hold global manufacturing “captive.”

The economic consequences could be far-reaching. Higher tariffs mean higher prices for imported goods, feeding inflationary pressures in the US and potentially forcing companies to restructure their supply chains. Meanwhile, the uncertainty could weigh on global growth, particularly in sectors such as autos, electronics, and defense, which depend heavily on rare earths and advanced software.

This latest flare-up comes just as both sides were attempting to stabilize relations following months of tariff escalation earlier this year, which had driven average US tariffs on Chinese imports to nearly 60 percent. With the current 90-day ceasefire between Washington and Beijing set to expire in mid-November, the renewed tensions now threaten to derail fragile trade negotiations and unsettle already cautious investors.

French political uncertainty pressures financial markets

France’s political instability has intensified following the resignation of Prime Minister Sébastien Lecornu, creating uncertainty over the government’s ability to deliver its 2026 budget and unsettling financial markets. The move comes at a delicate moment for President Emmanuel Macron’s administration, which faces growing challenges in stabilizing public finances amid rising debt and spending pressures.

Financial markets reacted swiftly to Lecornu’s departure. French equities and government bonds declined on Monday, while the yield on 10-year bonds, an indicator of borrowing costs, rose to nearly 3.6 percent, matching levels seen in Italy, a country often viewed as more fiscally fragile. The gap between French and German borrowing costs widened to around 0.85 percentage points, one of the largest spreads since 2012, reflecting investor concern about France’s fiscal trajectory.

The government faces a tight deadline to present a new budget proposal to parliament by October 13, leaving little time to pass it before year-end. If no agreement is reached, France could rely on a temporary “continuing budget” mechanism that allows 2025 spending levels to roll over into 2026. While this measure would avoid a shutdown of government services, economists note that it could worsen France’s fiscal position. Automatic increases in social spending, healthcare costs, and debt interest payments would likely push the deficit to around 6 percent of GDP, leaving fewer resources for other priorities, including defense.

The ongoing political turbulence follows a series of leadership changes. Lecornu is the third prime minister to leave office within a year, after predecessors struggled to secure parliamentary backing for deficit-reduction plans. Former prime minister François Bayrou resigned just weeks ago after failing to pass budget reforms aimed at controlling debt. The recurring difficulty in forming consensus has fueled speculation about the need for early elections, with some political figures urging Macron to consider bringing forward the 2027 presidential vote.

France’s fiscal challenges are rooted in elevated public spending following pandemic-era support measures and earlier tax cuts. Although France’s economic growth outlook for 2025 remains stronger than that of some European peers, its deficit and debt levels are among the highest in the euro area. The combination of political divisions and fiscal strain has led several credit rating agencies to downgrade France in recent months, and analysts warn that prolonged uncertainty could trigger further downgrades.

Economists estimate that political instability has already weighed on growth. According to models by the OFCE think tank, uncertainty since the dissolution of parliament in mid-2024 has reduced GDP by about half a percentage point, mainly through weaker investment and hiring. Business confidence has suffered as well: firms have delayed projects, and household savings remain unusually high, signaling caution among consumers.

Without renewed political clarity or a durable fiscal plan, France’s challenge is twofold: restoring confidence in its ability to manage public finances while ensuring that policy uncertainty does not further weaken economic activity.

Japanese markets surge after election of new prime minister

Japanese financial markets rallied sharply following Sanae Takaiichi’s election as leader of the ruling Liberal Democratic Party (LDP), a result that positions her to become Japan’s next prime minister later this month. Investors reacted to the outcome by betting on a new phase of government-led stimulus and continued accommodative monetary policy, an outlook that has become known in markets as the “Takaiichi trade.”

The Nikkei 225 index, tracking Japan's most valuable companies, jumped 4.8 percent, its largest one-day gain in over a year, while the broader Topix rose 3.1 percent to a record high. The yen fell 2 percent against the US dollar, slipping beyond the ¥150 threshold that traders closely monitor, reflecting expectations that Japan will maintain low interest rates even as other major economies keep policy tight.

Market participants expect that a Takaiichi administration would favor aggressive fiscal spending and encourage the Bank of Japan (BoJ) to preserve its ultra-loose monetary stance. In economic terms, fiscal stimulus refers to higher government spending or tax cuts aimed at supporting growth, while a loose monetary bias means keeping borrowing costs low to encourage lending and investment. Together, these policies tend to weaken the national currency and lift stock markets by making exports more competitive and liquidity more abundant.

Shares in sectors seen as potential beneficiaries of higher public spending such as pharmaceuticals, engineering, and semiconductors, rose strongly. Defense-related stocks also rallied, amid expectations that Takaiichi will expand military expenditure and align closely with US defense priorities. 

In contrast, financial stocks declined, as investors scaled back expectations of near-term rate hikes by the BoJ. The yield on Japan’s two-year government bonds fell slightly, indicating stronger demand, while yields on long-term bonds rose as investors anticipated heavier government borrowing to finance stimulus, creating what analysts described as a “steeper yield curve,” a sign of expectations for higher future growth and inflation.

Despite the market enthusiasm, political and institutional constraints could limit the scale of policy changes. Japan’s large public debt and the need to maintain confidence among investors may restrict the government’s ability to pursue expansive spending programs. Still, the immediate reaction shows how strongly financial markets expect continuity in Japan’s pro-growth, low-interest-rate approach.

Fears of an AI bubble ramp up

Global economic authorities are warning that the rapid rise in artificial intelligence–related stocks may be forming a financial bubble similar to the dot-com boom of the late 1990s. Both the International Monetary Fund (IMF) and the Bank of England (BoE) have noted that share valuations are approaching levels last seen before the dot-com crash, when over-optimism about the internet led to extreme overpricing of tech companies followed by a sudden collapse.

The fear of an “AI bubble” stems from the speed and size of recent gains in a small group of large technology firms that dominate the AI industry. The S&P 500 index, which tracks major US companies, has risen strongly this year, driven mainly by a handful of firms such as Nvidia, Microsoft, Google, and Meta. Together, these companies now make up nearly 30 percent of the index’s total market value, an unprecedented level of concentration. When so much of the market depends on a few firms, a decline in their share prices can drag down the broader market.

Valuations of these companies are also considered high by historical standards. For example, the “price-to-earnings ratio,” which compares a company’s stock price with its profits, shows that investors are paying far more for each dollar of expected earnings than usual. When valuations rise faster than profits, markets become vulnerable to sharp declines that occur when investors lose confidence or adjust expectations.

Officials such as IMF head Kristalina Georgieva warn that the optimism surrounding AI’s productivity potential could reverse quickly if the technology’s economic impact takes longer to materialize. A sudden loss of confidence could trigger a broad sell-off, lowering global growth and exposing financial vulnerabilities, especially in emerging economies. The BoE added that because today’s stock market is so heavily weighted toward technology, any AI-driven adjustment could have a larger-than-usual effect.

Overral, the concern is not about AI itself but about investor behavior. Markets may be pricing in too much future success too quickly. If earnings fail to keep pace with these expectations, valuations could fall sharply, repeating the pattern of previous technology booms that ended in painful corrections.

WTO says stockpiling and AI demand delay impact of US tariffs on global trade

The World Trade Organization (WTO) expects global goods trade to slow sharply in 2026 as the effects of recent US tariff measures feed through to the global economy. However, the slowdown will occur later than initially anticipated, with stronger-than-expected performance in 2025 driven by preemptive stockpiling and rising demand for products linked to artificial intelligence.

According to the WTO’s latest forecast, global goods trade is now expected to grow by 2.4 percent in 2025, up from an earlier projection of 0.9 percent, before decelerating to just 0.5 percent in 2026. The revision reflects how many companies have accelerated imports into the US ahead of higher tariffs, effectively pulling forward demand that would have taken place next year. These tariffs, part of a set of “reciprocal” trade measures introduced by the US administration in August, have raised the country’s effective tariff rate from under 2.5 percent to nearly 17 percent, the highest level since the 1930s.

Marc Bacchetta, the WTO’s chief economic modeller, said that while the tariffs have a clear impact, the main difference lies in timing. The organization noted that the absence of widespread retaliation from other major economies has supported trade in the short term. WTO Director-General Ngozi Okonjo-Iweala described the global response to US measures as “measured,” which has helped limit immediate disruption, though she also highlighted the high level of uncertainty surrounding future trade conditions.

Regional trade projections show uneven effects. The Middle East experienced the largest downward revision in export growth, moving from a forecast of 5.1 percent in April to a contraction of 0.9 percent in October. Meanwhile, trade among emerging economies has shown resilience, growing by 8 percent year-on-year in value terms and outpacing global trade growth of 6 percent.

A key factor supporting global trade this year has been the surge in demand for AI-related goods, such as semiconductors and telecommunications equipment, which grew by 20 percent in value during the first half of the year. This growth has helped offset some of the dampening effects of tariffs on traditional goods trade.

Beyond goods, the WTO also expects slower growth in services trade, including transport and tourism, as the effects of reduced goods flows spill over into other sectors. Global services exports are forecast to expand by 4.6 percent in 2025 and 4.4 percent in 2026, down from 6.8 percent in 2024.

Overall, the WTO’s latest outlook suggests that while global trade has remained more resilient than expected in 2025, the impact of higher US tariffs is likely to become more visible in 2026, as stockpiled inventories run down and global supply chains adjust to the new trade environment.
