JGB yields rise as inflation, fiscal concerns mount

TOKYO: Japanese government bond (JGB) yields rose on Wednesday as inflation and fiscal concerns mounted, overshadowing solid demand at a sale of super-long debt.

Here are a few details:

The benchmark 10-year JGB yield climbed 3 basis points (bps) to 2.750%.

The five-year yield increased 2.5 bps to 1.965%.

Yields move inversely to bond prices. JGB yields tracked a global move higher after US Treasury yields hit a two-month peak and euro zone yields edged up, as escalating US-Iran tensions lifted oil prices and revived inflation and rate-hike worries in major bond markets.

In an economic blueprint finalised on Tuesday, Prime Minister Sanae Takaichi’s administration said it will work with the private sector to funnel investments worth more than 370 trillion yen ($2.28 trillion) into targeted industries through fiscal 2040.

“Rising crude oil prices driven by escalating tensions in the Middle East are pushing up inflation expectations,” Takayuki Miyajima, senior economist at Sony Financial Group, said in a note.

“There remains deep-seated concern that the government’s ‘responsible, proactive fiscal policy’ may lead to increased government bond issuance and fiscal expansion in the future.”

The Ministry of Finance sold about 300 billion yen in 40-year JGBs on Wednesday.

The sale’s bid-to-cover ratio, a measure of demand, rose to 2.82, the highest since March 2025.

Market participants remained focused on the Bank of Japan’s next policy meeting, with expectations firming for the central bank to keep rates on hold next week but potentially signal a faster pace of tightening as inflation risks persist.

The 20-year JGB yield climbed 3 bps to 3.630%.

The 30-year yield added 0.5 bp to 3.890%, while the yield on the 40-year JGB, Japan’s longest tenor, rose 1 bp to 3.9%. ‑Reuters
