Japanese Yen: Intervention risk and JGB appeal – BNY

BNY’s Geoff Yu notes USD/JPY slipping back below 153 as markets heed U.S. Treasury Secretary Scott Bessent’s warning on testing Japanese Yen intervention. The report stresses that a sustained move depends on a broader Bank of Japan tightening cycle. Fitch Ratings adds that rising JGB yields and expected faster policy rate hikes in 2026–2027 should support the Yen and domestic bond demand over time.

Yen stability hinges on BoJ path

"JPY consolidates gains. U.S. Treasury Secretary Scott Bessent’s warnings against testing the authorities’ resolve on JPY intervention appear to be resonating."

"USD/JPY moved below 153 again overnight, albeit with limited follow-through. The more important response must come from the BoJ, particularly through establishing a tightening cycle that extends well beyond September."

"This week’s data confirming Japanese selling of U.S. Treasurys have had little immediate market impact, but the headline numbers underscore the risks to U.S. paper and the importance of JPY stability."

"Fitch Ratings has said Japanese investors’ move into domestic bonds is gradual rather than abrupt. Higher JGB yields are encouraging insurers to sell low-coupon holdings and reinvest in newly issued higher-coupon paper, boosting future coupon income and policyholder dividends under Japanese GAAP."

"Fitch expects policy rates to rise faster than markets are predicting in 2026-2027, further supporting the yen and JGB demand."
