JGB yields rise as higher oil prices stoke inflation worries

Tokyo, Japan experienced a rise in government bond yields on Friday due to heightened concerns over the Middle East conflict and its impact on oil prices. The benchmark 10-year Japanese government bond (JGB) yield climbed to 2.875%, marking a 3 basis point increase from the previous day. This comes after two days of declines following the JGBs' multi-decade highs.

The US has announced the implementation of the most stringent sanctions ever imposed on Iran, as Treasury Secretary Scott Bessent stated on Thursday, as Washington intensifies its economic pressure to bring an end to the six-month conflict. Crude oil prices surged by approximately $2 overnight, contributing to the bond yield surge.

Analysts attribute the stronger bond yields to ongoing concerns about instability in the Middle East region, which tends to negatively impact Japanese bonds. Additionally, there is a growing expectation that the Bank of Japan will raise interest rates at its upcoming policy meeting on September 17-18, further fueling the bond yield increase.

Recent data revealed that core consumer inflation accelerated in July, reinforcing the notion of tighter monetary policy. Among the shorter-duration bonds, the 2-year JGB yield increased by 0.5 basis points to 1.675%, while the 5-year yield rose 1.5 basis points to 2.115%. Longer-term bonds, which are more influenced by inflation expectations, also saw an uptick, with the 20-year yield climbing 5 basis points to 3.76% and the 30-year yield surging 5.5 basis points to 4.06%.
