Michael Burry flags yen strength as trigger for unwinding global carry trades
Burry: a stronger yen could pull money back to Japan and hit US assets

​Michael Burry says the Japanese yen is “long, long overdue” for a trend reversal, warning that a stronger yen could trigger a meaningful shift in global capital flows. 

The debate intensified after the New York Fed reportedly reached out to trading counterparties on USD/JPY, just as Japanese officials stepped up verbal intervention against yen weakness, reports MarketWatch.

The dollar hit around 159 yen on Friday before sliding to roughly 154.17 by Monday morning, reflecting rising sensitivity to policy signals. Burry’s main argument is that a yen rebound would encourage repatriation — money that previously left Japan for higher returns abroad could start moving back home. In his view, that would mark a major reversal of the cross-border flow regime that has supported U.S. stocks and bonds. The core risk is that higher Japanese rates combined with lower U.S. rates would remove a key tailwind for American assets. Even if the move begins as a currency adjustment, the larger story is about shifting global liquidity direction.

Why a stronger yen could pressure U.S. markets

Burry frames the potential impact through the lens of interest-rate differentials and investor behavior. For years, Japan’s low-rate environment made it attractive to borrow cheaply in yen and invest elsewhere — a dynamic that indirectly boosted demand for U.S. assets. If Japan’s rates rise and the U.S. moves toward cuts, that incentive weakens, and global capital may start rotating back toward Japan. Burry argues that this could weigh on both U.S. stocks and bonds, reversing the trend that helped inflate valuations during the previous cycle. 

The concern is not only about currency translation, but also about positioning unwind and risk appetite. A stronger yen can tighten financial conditions by forcing leveraged trades to close out, which often shows up as short-term volatility in equities. In simple terms: if money goes back to Japan, less marginal demand supports U.S. risk assets. That’s why the yen’s direction matters far beyond FX desks.

Morgan Stanley sees 145 as “fair value,” but stays bullish on U.S. stocks

Morgan Stanley’s Michael Wilson said many Japanese investors expect USD/JPY to trade toward 140–145, and the bank’s FX team also estimates fair value near 145 based on terminal-rate pricing. He acknowledged that a stronger yen could create short-term volatility, but argued it may ultimately support Japanese equities through improved market stability and healthier long-term positioning. 

Unlike Burry, Wilson remains confident in the U.S. equity outlook, pointing to expected 17% growth in S&P 500 earnings, broader earnings contribution, and rising “animal spirits” tied to capex and improving activity. Still, he flagged FX-driven turbulence as a tactical risk, especially if the yen move accelerates quickly. The S&P 500 ended Friday at 6,915, marking its second straight weekly decline, showing markets are already entering a more fragile phase. The key takeaway: yen strength may not automatically “break” U.S. stocks, but it could become a catalyst for sharper volatility and a rotation in global flows.
