Investors and analysts are monitoring a shift in the U.S. dollar's role as a global refuge as record amounts of foreign capital enter American markets to fund artificial intelligence (AI) development. Financial strategists from Nomura and Wells Fargo noted on Wednesday, Oct. 28, 2026, that the heavy concentration of foreign money in U.S. technology stocks and corporate bonds has made the currency more sensitive to price fluctuations. This "hot money" flow, characterized by institutional investors who are sensitive to changes in growth and interest rates, could potentially weaken the dollar’s traditional status as a safe asset during market downturns.
The surge in AI-related investment follows a period of American economic growth that has outpaced other nations, supported by higher interest rates and strong demand for U.S. assets. Foreign capital has targeted mega-cap technology firms, hyperscaler corporate bonds, and power-grid infrastructure. Analysts from CIBC Capital Markets reported that this trade has pushed U.S. interest rates higher, which in turn supported the dollar's value. However, the concentration of these flows has created what some experts describe as a crowded bet on the American economy.
Evidence of this shift appeared during the week of Oct. 19, 2026, when AI stock valuations declined. During that period, investors seeking safety moved toward the Japanese yen and the Swiss franc rather than the dollar. While the dollar maintained slight gains against the euro, analysts at Convera stated that the relationship between the AI trade and the dollar has become more visible. Concerns have specifically targeted high-debt companies like CoreWeave, where widening credit default swap spreads—a type of insurance against debt default—have added pressure to the stock market.
The scale of this exposure is reflected in the trade-weighted dollar, which has remained above its long-run average for 12 consecutive years, the longest stretch since 1973. If the AI investment cycle slows, the Federal Reserve may be pressured to cut interest rates to support growth, which would further reduce the yield advantage that currently attracts foreign investors. Unlike the dotcom peak in 2000, the U.S. now faces a large fiscal deficit, which limits the government's ability to provide stimulus without affecting debt markets.
What happens next depends on whether AI infrastructure investments generate expected returns. If returns disappoint, credit spreads may widen, potentially forcing technology companies to reduce spending on hardware and energy. Analysts at Wells Fargo indicated that the dollar’s vulnerability is a key factor to watch heading into 2027. While a severe global shock could still cause a temporary scramble for dollars to cover liabilities, as seen in 2008 and 2020, the longer-term trend may favor other currencies if U.S.-specific credit and growth problems persist.
