JGBs edged lower in the morning Tokyo session, mirroring overnight falls in U.S. Treasurys. The two markets normally move in tandem, and the recent spike in crude oil prices combined with yen weakness may weigh on JGBs. Higher oil levels and a weaker yen typically raise inflation expectations in Japan, potentially prompting the BOJ to raise rates sooner. Marcel Thieliant, head of Asia-Pacific at Capital Economics, noted that “with crude oil prices approaching recent peaks and the yen falling to fresh lows against the dollar, the central bank’s concerns about upside risks to inflation won’t have dissipated.” The 10‑year JGB yieldanity is 2.5 bps higher at 2.795%.

The close link between JGBs and U.S. Treasurys underscores global risk sentiment: when U.S. yields climb, Japanese bonds often follow suit. Market participants watch the BOJ’s policy stance closely, especially as oil-driven inflation could force a quicker tightening cycle. Meanwhile, the yen’s continued slide adds pressure on the Japanese economy, potentially reshaping capital flows and bond pricing.

Investors remain cautious, balancing the allure of higher yields against the backdrop of rising inflation and a volatile currency environment.
