AI investment boom puts the dollar’s hot-money flows under fresh scrutiny

Record foreign equity inflows and a surge of capital into artificial-intelligence infrastructure are raising the risk that the US dollar could become more sensitive to a reversal of the AI trade, according to a Reuters analysis published on Wednesday.

The concern is not that an AI-led market correction would mechanically push the dollar lower. Rather, the concentration of recent investment flows could make the currency more exposed if investors begin to unwind positions tied to US technology and growth assets. Analysts cited by Reuters included strategists at Nomura, Wells Fargo, Convera, CIBC and Scotiabank.

Why AI flows matter for the currency

Large overseas purchases of US equities have helped channel global savings into American markets at the same time that companies have been committing enormous sums to data centers, chips and other AI infrastructure. If confidence in the expected returns from that spending weakens, the resulting portfolio adjustments could reduce demand for US assets and send capital toward other markets.

Recent moves offered an early indication of that sensitivity. The yen and Swiss franc attracted haven flows during the previous week as investors reassessed risk, Reuters reported. Those moves do not establish a lasting trend, but they show how quickly currency markets can respond when crowded trades are questioned.

Dollar downside is a risk, not a forecast

A US-specific credit or growth shock, potentially accompanied by expectations of Federal Reserve interest-rate cuts, would be one route to dollar weakness. Lower expected US returns can reduce the incentive for foreign investors to hold dollar-denominated assets and can encourage money to move elsewhere.

But the direction is not guaranteed. Reuters noted that the dollar did not automatically decline after the Nasdaq’s peak in 2000; it remained firm for nearly two years. In a funding panic, investors may initially seek the liquidity of the US currency even while selling US equities.

The analysis therefore describes a vulnerability rather than a confirmed turning point. The dollar’s next major move will depend on whether AI investment continues to support US growth and asset valuations, or whether a broader shock changes the balance between returns, interest rates and demand for safe-haven liquidity.
