The Japanese Yen Is Sending A Warning To Stocks

The Japanese yen's recent broad strengthening signals rising odds of a Bank of Japan rate hike, unsettling global FX and risk asset markets. Equity markets remain complacent, with low VIX and implied correlations, despite historical links between yen strength and volatility spikes. USD/JPY and AUD/JPY have not yet triggered equity market reactions, but further yen gains could swiftly elevate volatility and correlations. A faster-than-expected BOJ hiking cycle risks a sharp risk-off event, while a dovish stance could stabilize the yen and markets.
