Japanese Bond Yields Are Rising and It Might Take Down the Stock Market with It

Why It Matters

The end of cheap yen funding could strip a key source of leverage from US and global markets, amplifying volatility and forcing central banks into emergency dollar liquidity interventions that would underscore systemic interdependence.

Summary

Investors have long sustained US stocks, Treasuries and emerging markets through a roughly $500 billion yen carry trade—borrowing near-zero yen, converting to dollars and investing abroad. That dynamic is unraveling as the Bank of Japan has rapidly tightened policy, lifting short rates to 0.75% and sending the 10-year yield from ~0.10% in 2022 to over 2.10%, while the 40-year bond topped 4% as markets reassess Japan’s 237% debt-to-GDP. The swift repricing has already triggered violent equity moves in Japan (a 12% one-day Nikkei drop in August 2024) and risks forcing a large, disorderly repatriation of leveraged yen funding. If the unwind accelerates, US authorities may be compelled to provide dollar liquidity—potentially via Fed swap lines—to prevent global market contagion.
