Beyond Tariffs: Two Hidden Threats to a Stock Market Crash Under Trump

While much attention focuses on Trump’s tariff policies, a more troubling question looms: is stock market crashing inevitable given deeper structural problems? Two overlooked factors—the deteriorating U.S. dollar and unsustainable AI infrastructure spending—pose greater threats to market stability than import taxes alone, and both could trigger a significant correction in 2026.

The Weakening Dollar: Your Stock Market Gains Are Shrinking

When investors see the S&P 500 reporting an 18% gain, they assume their actual purchasing power grew by roughly that amount. But that’s not the full story. The U.S. dollar’s value directly impacts what those gains are actually worth on the global stage.

During 2025, the dollar index fell 8%—a decline that significantly reduced the real value of American stock market returns. To put this in perspective: the S&P 500’s headline return of 17.9% for the year actually translated to much lower real gains when you account for currency depreciation. The euro, for example, strengthened nearly 15% against the dollar in the same period, meaning investors holding overseas assets saw even more dramatic erosion of real returns.

This currency weakness isn’t accidental—it’s rooted in Trump’s policies and their ripple effects through the economy. The biggest culprit: Trump’s pressure on the Federal Reserve to slash interest rates. Investors increasingly view this pressure as political interference in monetary policy, potentially threatening the institution’s independence. As the central bank’s autonomy becomes compromised, markets lose confidence in its ability to manage inflation responsibly.

Meanwhile, the U.S. budget deficit is ballooning toward a projected $1.9 trillion, creating enormous pressure on borrowing costs. Trump wants lower rates to reduce government debt servicing, but maintaining weak monetary policy amid massive deficits typically weakens a currency. This trend is expected to accelerate through 2026.

Unsustainable AI Spending: The Bubble Hiding in Plain Sight

Despite economic uncertainty, 2025 delivered impressive headline numbers: 2.2% GDP growth and that aforementioned S&P 500 rally. But dig deeper, and you’ll find these gains concentrated in a dangerously narrow slice of the market. The Magnificent Seven—mega-cap tech stocks heavily exposed to artificial intelligence—accounted for half of the S&P 500’s three-year gains. Nvidia alone powered 15% of the index’s 2025 returns.

This concentration creates a critical vulnerability. While chipmakers and data center equipment suppliers continue printing money, the companies actually building consumer-facing AI products are hemorrhaging cash. OpenAI exemplifies this problem: the company is expected to burn through $14 billion this year despite its dominance in generative AI. The reason? Large language models haven’t yet transformed into profitable business models at scale.

Yet the market continues valuing these speculative AI firms as if profitability is guaranteed. The cyclically adjusted price-to-earnings (CAPE) ratio—which smooths out market cycles by comparing current stock prices to inflation-adjusted earnings over the past decade—now sits at 40. This is the highest level since 2000, right at the peak of the dot-com bubble.

The real problem lurks in corporate balance sheets. Massive data center investments will soon trigger enormous depreciation charges, weighing down reported earnings. As these expenses pile up, the market may finally question whether current valuations for AI-dependent companies make sense. When skepticism sets in, expect a swift repricing—and the broader market will follow.

Why Market Corrections Are Part of the Cycle

Here’s the crucial reality: stock markets don’t move in one direction forever. History shows consistent patterns of boom-and-bust cycles. Every crash has been followed by recovery over longer timeframes, even the most severe downturns. This isn’t optimism—it’s documented fact.

The question isn’t whether a stock market crash might happen, but when, and how investors can prepare. The good news: preparation exists, and it’s straightforward. Diversification across multiple asset classes—stocks, bonds, commodities, real estate—insulates portfolios from sector-specific shocks. When your holdings span different industries and economies, no single collapse can devastate your overall wealth.

Additionally, downturns create opportunities. When panic selling drives valuations down, patient investors can acquire quality assets at significant discounts. The 2008 financial crisis and subsequent recovery proved that timing doesn’t require perfection—broad-based diversification and long-term commitment do.

Preparing for the Next Correction

The convergence of dollar weakness, unsustainable AI spending, and political pressure on monetary policy creates a volatile environment. Rather than attempting to predict the exact timing of a stock market crash correction, investors should focus on what’s controllable: portfolio construction and disciplined strategy.

Review your asset allocation. Are you overexposed to technology or single sectors? Consider rebalancing toward uncorrelated assets. For those with time before retirement, downturns aren’t catastrophes—they’re shopping opportunities. The key is ensuring you have the financial stability to hold through corrections without panic selling.

The most successful investors aren’t those who dodge every crash. They’re the ones who built portfolios resilient enough to weather them, then capitalized on the inevitable recovery that follows.
