Japan 5-year government bond yield rises to the highest since 2008

Japan's 5-year government bond yield rose to 1.165%, the highest level since October 2008, according to LSEG data.

Yield on the 10-year government bond gained more than 3 basis points to 1.575%, hovering near the highest levels since late 2008, while yield on the 30-year government bond was little moved at 2.601%.

Bank of Japan Governor Kazuo Ueda has taken in stride the recent rises in bond yields and reiterated on Monday the central bank would continue to hike interest rates if inflation stays on track to hit its target band, despite potential losses on the government bond holdings.

"We have said that we will continue adjusting the degree of monetary easing if underlying inflation is likely to approach 2%," he said.

President Trump said the U.S. will impose 25% tariffs on countries that buy oil and gas from Venezuela, as he seeks to increase pressure on President Nicolas Maduro and China.

Venezuela exported about 660,000 barrels per day in 2024, according to data from Kpler. China was the largest destination for the South American nation's crude exports, purchasing 270,000 barrels per day last year.

"This announcement by the Trump administration appears to be one more action targeting China," Matt Smith, an oil analyst at Kpler, told CNBC.

Brent crude futures rose 61 cents, or 0.85%, to $72.77 a barrel by 1:15 p.m. ET. U.S. West Texas Intermediate crude was up 59 cents, or 0.86%, at $68.87.
