Japan 10-Year Yield Eases as Oil Prices Retreat

Japan’s 10-year government bond yield fell to around 2.76% on Monday, retreating from two-week highs as oil prices declined after the US and Iran suspended strikes against each other over the weekend amid efforts to revive diplomacy. Japan remains heavily reliant on oil imports from the Middle East, leaving its economy vulnerable to supply disruptions and sharp swings in crude prices. On the domestic front, approval ratings for Prime Minister Sanae Takaichi declined as the government's efforts to rein in inflation continued to fall short of household expectations. Japanese bond yields had climbed to 30-year highs earlier this month amid a worsening fiscal outlook, with Takaichi’s administration recently unveiling a massive spending package that could further increase the country's debt burden. Markets are also pricing in a faster pace of Bank of Japan policy tightening as persistent inflation and the weak yen continue to support expectations for additional rate hikes.

Japan’s 10-year government bond yield climbed to around 2.81% on Friday, rising for a fourth consecutive session and reaching a two-week high as expectations for further Bank of Japan rate hikes increased. The move came as Japan’s annual consumer inflation accelerated to a six-month high of 1.7% in June, reinforcing expectations for continued BOJ tightening later this year, though the central bank is widely expected to hold rates steady at next week’s meeting. At the same time, Brent crude climbed above $100 per barrel amid escalating Middle East tensions, raising fears of supply disruptions and higher import costs. Separately, concerns over Japan’s fiscal outlook also weighed on government bonds, with growing debt-service costs becoming a key focus as long-term borrowing costs stayed near multi-decade highs. US Treasury yields, with the 10-year yield above 4.7%, also added upward pressure on Japanese bond yields as investors reassessed the global interest rate outlook.

Japan’s 10-year government bond yield climbed to around 2.77% on Thursday, rising for a third consecutive session as expectations for faster Bank of Japan rate hikes strengthened. Reports that BOJ officials were open to faster policy tightening lifted the broader JGB curve, with swap markets pricing around an 80% chance of a 25-basis-point rate hike to 1.25% in October, up from around 70% previously. The yen remained near a four-decade low against the dollar, while rising oil prices amid escalating US-Iran tensions added to inflation concerns and reinforced expectations that the BOJ will continue normalizing policy. Policymakers have remained alert to upside price risks from a weaker yen and higher fuel costs. Meanwhile, Japan’s 2-year government bond yield climbed to a 31-year high of 1.49% as investors further adjusted expectations for the BOJ’s rate path, while rising US Treasury yields also weighed on Japanese bonds.
