USD/JPY falls to 156.40 as 10-year JGB yield tops 3% on BoJ hike talk

USD/JPY dropped to 156.40 on September 3 as the yen strengthened broadly following hawkish commentary from Bank of Japan board member Takata, who urged the central bank to move nimbly on rate hikes. The remarks helped push the 10-year Japanese government bond yield above 3% for the first time since 1996, a milestone that materially narrows the US-Japan yield differential that has underpinned dollar strength for years. The surge in JGB yields raises the funding cost of yen-financed carry trades, increasing the risk of position unwinding across high-yield and emerging-market crosses. Combined with softening US data and a more dovish Federal Reserve tone, the rate-convergence dynamic is delivering a two-sided squeeze on long USD/JPY exposure. Traders should monitor 156.00 as the immediate psychological support, with a sustained break exposing deeper downside, while 157.00–158.00 now serves as resistance. Yen crosses including EUR/JPY, GBP/JPY and AUD/JPY remain most exposed to further carry-trade liquidation if JGB yields continue climbing.
