Hedging-cost changes
Updated
What it is
This indicator tracks how expensive it is for Japanese investors to hedge foreign-currency (mainly US dollar) exposure back into yen, and conversely how much dollar-based investors earn hedging yen exposure into dollars. The cost is driven mainly by the US-Japan interest-rate differential and cross-currency basis conditions. Rising hedging costs for Japanese investors discourage unhedged foreign buying and can accelerate repatriation of capital back to Japan.
Why it matters lately
Through much of the prior year, USD/JPY hedging costs for Japanese investors exceeded 5% annualized, making fully hedged foreign bond holdings expensive to maintain. From the other side, dollar-based investors hedging yen exposure into dollars have been earning roughly 3% annualized, and after hedging, 10-year and 30-year JGB yields have looked as high as roughly 5.6% and 6.8% respectively to dollar-based buyers, reflecting the interest-rate differential embedded in the hedge. As the Bank of Japan raised rates to 1.25% in September 2026, this differential-driven hedging-cost dynamic remained a key input to Japanese investors' repatriation decisions.

Inference (AA): Rising yen hedging costs for Japanese investors are AA's proxy for mounting pressure on Japanese institutions to repatriate unhedged foreign holdings.
