TOKYO, July 22 (Reuters) - 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 U.S.

Treasury yields hit a two-month peak and euro zone yields edged

up, as escalating U.S.-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%.
