In a recent campaign-style speech, Donald Trump pointed to soaring stock prices and rising 401(k) values as proof of economic strength. He is not wrong on the surface: all major U.S. stock indices posted double-digit gains last year. Yet markets are forward-looking, and with the November midterm elections still months away, the very stock market Trump celebrates could turn into a political vulnerability.
Markets priced for perfection
The dominant feature of the current U.S. equity rally is extreme optimism. Valuations suggest not just confidence, but an assumption that the economy will deliver near-flawless outcomes.
By the Cyclically Adjusted Price-Earnings (CAPE) ratio, the S&P 500 is trading at more than twice its long-term average, approaching levels last seen before the dot-com crash of 2001. The Buffett Indicator — the ratio of total U.S. stock market capitalisation to GDP — is at an all-time high, roughly 50% above its 2008 peak. Historically, such extremes have preceded significant corrections rather than sustained rallies.
Investor exuberance as a warning signal
Another red flag is sentiment. According to surveys by Bank of America, fund managers are more bullish than at any point in the past three years, while their cash holdings have dropped to record lows. When professional investors are fully invested and highly optimistic, markets often become fragile — with little buffer left if bad news arrives.
In such an environment, even modest economic disappointments can trigger sharp sell-offs.
Fiscal stress and the bond market risk
One potential trigger lies in U.S. public finances. The federal government is running an annual budget deficit of around $2 trillion, financed heavily by foreign investors. At the same time, Trump’s repeated attacks on the independence of the Federal Reserve raise fears of political pressure to keep monetary policy loose.
If investors conclude that inflation will be used to erode the real value of government debt, bond markets could react swiftly. A sell-off in U.S. Treasury bonds would push long-term interest rates higher, raising borrowing costs for mortgages, car loans, and corporate investment — and undermining equity valuations.
The AI boom and concentration risk
Another domestic vulnerability is the artificial intelligence investment boom. A large share of recent U.S. GDP growth has been driven by AI-related spending, creating concerns of an asset bubble.
The so-called “Magnificent Seven” — Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia, and Tesla — together account for roughly 35% of the S&P 500’s total valuation. Such concentration means that a correction in a handful of technology stocks could drag down the entire market. Oracle’s recent 30% stock-price fall is being watched closely as a potential early warning.
External shocks from abroad
Risks are not confined to the U.S. economy. China’s growth model remains heavily dependent on exports and investment, with a trade surplus exceeding $1 trillion. This increases the likelihood of protectionist responses from the U.S. and Europe, threatening global trade flows.
Japan presents another potential shock. Concerns over Prime Minister Sanae Takaichi’s fiscal stance have sparked fears of a “Liz Truss moment,” similar to the UK crisis of 2022. A spike in Japanese bond yields could unwind the yen carry trade, forcing Japanese investors to repatriate capital that has been supporting U.S. financial markets.
Geopolitics as a market disruptor
Finally, geopolitics remains a persistent wild card. The recent U.S. military operation in Venezuela, Chinese military drills near Taiwan, and stalled diplomacy over Ukraine all underscore how quickly global tensions can escalate.
Any conflict involving Taiwan would be especially destabilising for markets, given its role in producing over half the world’s semiconductors. Even a small increase in perceived risk can reprice assets sharply when valuations are stretched.
Political pride and market vulnerability
By foregrounding stock market performance as proof of economic success, Trump has tied his political narrative to an inherently volatile indicator. If markets correct by 10–20% — a plausible scenario given current valuations and risks — today’s badge of success could quickly become tomorrow’s liability.
