The Past Week’s Surge in the U.S. Dollar Index

The past week’s surge in the U.S. Dollar Index represents more than just a market correction. It signals a troubling return to form after the currency’s historic first-half collapse, losing nearly 11% in the worst performance since the index’s creation in the early 1970s. But this recovery should not provide comfort to investors. Instead, it masks a more sinister pattern that bears an uncomfortable resemblance to the conditions preceding October 1987’s Black Monday crash.

The Relationship Between Currency Strength and Market Performance 

The relationship between currency strength and market performance has never been straightforward. Statistical analysis reveals this complexity clearly: since 1973, changes in the dollar index have explained merely 1% of contemporaneous changes in the S&P 500’s earnings per share. The correlation between these variables has swung wildly, ranging from 0.44 to negative 0.83 depending on the five-year period examined. This inconsistency extends to the dollar’s role as a leading indicator, where trailing 12-month changes explain just 0.4% of subsequent earnings growth rates.

The Real Concern: Political Dynamics 

Yet statistics tell only part of the story. The real concern lies not in mathematical correlations but in the dangerous political dynamics currently at play. Today’s financial environment mirrors the toxic combination that preceded the 1987 crash with frightening precision: an overvalued stock market, aggressive presidential pressure on the Federal Reserve, and the deliberate pursuit of dollar devaluation as economic policy.

Parallels with 1987 

The parallels run deeper than mere coincidence. In 1987, the dollar index had already fallen 7% by the time of the crash, but the Reagan administration was actively pushing for further declines. Treasury Secretary James Baker publicly pressured the Federal Reserve to slash interest rates, explicitly targeting both economic stimulus and additional dollar weakness. The markets interpreted this currency manipulation as a declaration of economic warfare, making risk assets suddenly too dangerous to hold.

The Current Administration’s Approach 

The current administration’s approach follows this same reckless playbook. Aggressive pressure on the Fed to lower rates, combined with an apparent willingness to sacrifice dollar strength for short-term economic gains, creates the exact conditions that spooked investors in 1987. The only difference is that today’s stock market is even more overvalued than it was then, making the potential for catastrophic losses even greater.

The Impact of Extreme Currency Movements 

Market participants should remember that extreme currency movements can indeed command attention, regardless of their typical lack of correlation with stock performance. When presidential administrations actively pursue dollar debasement as policy, they signal to global investors that currency stability has been sacrificed for political expediency. This creates a crisis of confidence that transcends traditional market relationships.

The Prospect of a Modern Currency War 

The prospect of a modern currency war makes risk assets particularly vulnerable. Foreign investors, already nervous about dollar stability, may begin dumping American securities en masse if they perceive the administration’s policies as fundamentally destabilizing. Domestic investors, meanwhile, face the uncomfortable reality that their government is actively working to devalue their holdings through monetary manipulation.

Lessons from History 

History rarely repeats exactly, but it often rhymes with uncomfortable precision. The 1987 crash serves as a stark reminder that when political pressure meets currency manipulation in an overvalued market, the results can be catastrophic. A single data point cannot guarantee future outcomes, but the confluence of factors currently aligning suggests that investors ignore these parallels at their own peril.

The Dollar’s Recent Strength 

The dollar’s recent strength may have provided temporary relief, but the underlying dynamics remain unchanged. As long as the current administration continues its aggressive campaign against Fed independence and dollar stability, the conditions for a repeat of 1987’s disaster will continue to build. Smart investors would be wise to heed history’s warning before it becomes tomorrow’s painful lesson.
