The U.S. dollar’s traditional role as a safe-haven asset is facing new challenges due to the influx of foreign capital chasing returns from the AI boom. Investors have long relied on the dollar during market downturns, but the growing concentration of foreign money in U.S. mega-cap equities, hyperscaler corporate bonds, and power-grid infrastructure has made it a crowded bet on American exceptionalism. This shift has tied the dollar’s strength to the performance of the AI trade, raising concerns about its resilience if the narrative falters.
Last week provided an early warning when AI valuations came under pressure, leading to haven flows favoring the Japanese yen and Swiss franc over the dollar. The greenback managed modest gains against the euro, primarily due to concerns over French civil unrest. Analysts note that the relationship between the AI trade and the dollar has become more visible, with foreign flows into U.S. equities reaching record highs while foreign direct investment lags. This dynamic resembles the “hot money” flows typical of emerging markets, where institutional allocators may quickly buy or sell based on reassessments of U.S. growth, rates, or tech valuations.
If the AI trade unwinds, the dollar could face vulnerabilities on multiple fronts. Weaker growth might force the Federal Reserve to cut rates, eroding the dollar’s yield advantage. Slower domestic investment could undermine the exceptionalism narrative, while fading institutional demand for U.S. corporate bonds and equities would weaken a major source of structural support. Analysts suggest that any sustained weakness could be a gradual process, taking months or years, but an equity rout alone would not automatically sink the dollar. Historical precedents, such as the Nasdaq peak in March 2000, show that the dollar can remain firm for an extended period before cracking under stress.
The AI buildout is more U.S.-centric than previous tech booms, with the real trade-weighted dollar staying above its long-run average for 12 consecutive years, the longest stretch on record. Concerns about riskier parts of the AI universe, such as heavily indebted neocloud companies like CoreWeave, have already widened credit default swap spreads sharply in recent weeks, adding pressure on stocks. Washington’s large fiscal deficit compared to a surplus near the 2000 tech peak leaves less room for counter-cyclical stimulus without unsettling debt markets. The key signal for analysts is whether stress becomes a U.S.-specific credit and growth problem that could change expectations for Fed policy, potentially benefiting the yen at the dollar’s expense.
