Japan's government bonds saw an increase on Monday, leading yields to move further away from recent multi-decade highs. According to Jin10, this shift comes as signs of easing tensions in the Middle East have alleviated market concerns over inflation. Last week, Japan's 10-year government bond yield reached a 29-year high but fell by 5 basis points to 2.710% today. Similarly, the 30-year yield, which had previously hit a historic high, decreased by 5.5 basis points to 3.955%.

Japan's heavy reliance on imported energy means that the rise in oil prices due to Middle East conflicts has put pressure on the country's economic and inflation outlook. Reports last week suggested that Sanae Takaichi might introduce a supplementary budget, which heightened fiscal concerns and further impacted Japanese government bonds.

Yunosuke Ikeda, head of macro research at Nomura Securities, noted, "There remains significant uncertainty among market participants regarding Sanae Takaichi's commitment to fiscal discipline. Many investors believe it is not yet the right time to buy Japanese government bonds, even though they find the current yield levels attractive and see limited room for further significant yield increases." He added, "Takaichi is well aware of market concerns, and I think investors might be pleasantly surprised in the next two months."
