Deutsche Bank Flags $20 Trillion in Foreign US Stock Holdings Exposed to AI Selloff

A $20 Trillion Paper-Gain Dependence

Deutsche Bank has warned that an AI-driven selloff in US equities could drag the dollar down with them, breaking a decade-old pattern in which falling stocks lift the greenback. The case was set out by George Saravelos, the bank’s global head of FX research, in a client note published Friday. “We estimate that roughly 90% of the $20+ trillion value of US equities owned by foreigners is attributable to price appreciation rather than underlying buying,” the note stated. Saravelos argued that foreign buying of US stocks now funds the entire US current account deficit, the gap between what the United States spends abroad and what it earns from the rest of the world. The dollar’s haven behaviour has rested on a simple mechanism: when US stocks fell, foreign investors skipped currency hedging because a falling market usually lifted the dollar, cushioning them from exchange-rate losses on top of price losses. That cushion, Saravelos wrote, flips when the shock originates in the United States itself. Investors scrambling to hedge their exposure must then sell dollars, turning the reserve currency into a source of selling pressure rather than a refuge. A summary of the note circulated by the Walter Bloomberg terminal feed put the stakes plainly: the US dollar may lose its traditional safe-haven status during an AI-driven stock market correction. The warning centres on a $20 trillion pool of foreign-owned US stock holdings whose combined market cap rests, by the bank’s own estimate, almost entirely on AI-era price gains rather than fresh capital inflows.

April 2025 Precedent, Friday's Session

The mechanism has a recent precedent. After US President Donald Trump’s Liberation Day tariff announcement in April 2025, the Bank for International Settlements found that hedging by non-US investors fed the dollar’s slide. Its bulletin documented how currency-hedging flows, rather than equity selling alone, drove the greenback lower once the shock came from Washington. Hedging here means buying protection against dollar weakness, which mechanically requires unhedged foreign investors to sell dollars when they seek cover. Friday’s session offered no confirmation the pattern has returned. The S&P 500 traded 1.28% lower by mid-afternoon UTC on market data, with Intel dropping almost 30% after a weak forecast and Amazon sliding alongside other technology names; semiconductor and cloud names carry the spending expectations behind the AI trade the note addresses. The US Dollar Index, which tracks the dollar against six major currencies, edged up 0.09%. Gold dropped 2.44% and Bitcoin traded lower, leaving both among 2026’s worst major assets despite gold’s best month since 1999 in August. The note named its own signal to watch: falling US real yields, meaning bond returns after inflation, alongside weaker stocks and a weaker dollar. That combination would show markets cutting their AI spending forecasts. Friday’s trading did not show it, and the dollar held firm. The bank’s reported comments did not address gold or Bitcoin, though both are priced in dollars and both rallied in August on a weaker dollar and Federal Reserve rate bets. Saravelos did not predict a crash. He described dollar risks as more two-sided than markets have priced in recent weeks: a shock starting outside the United States would still send money into the dollar.

For our desk, the note matters less as a crash call than as a condition set. Friday’s tape backed that caution: a 0.09% gain in the dollar index against a 1.28% equity decline is a session, not a regime change. The trade that matters is the one the note defines. If US real yields fall while stocks weaken, hedging flows flip from dollar-neutral to dollar-selling, and dollar-priced assets such as gold regain the tailwind that produced their August rally on weaker-dollar and Federal Reserve rate bets. Until that mix appears, the haven bias holds.
