Vanguard, RBC BlueBay Scoop Up Battered 30-Year Japanese Bonds

The selloff in Japan’s long-dated bonds is drawing international investors, who expect the securities to rebound as global trade turmoil abates.

Japanese 30-year government borrowing costs approached 3% this week for the first time in almost 25 years, and there are fears of further rises as tariff-linked uncertainty sends investors toward shorter-dated bonds. Yet, some funds, including Vanguard and RBC BlueBay Asset Management, see the moves as a green light to buy more of the super-long securities.

They point to the likelihood of a tariff detente with the US, allowing the Bank of Japan to resume its interest-rate hikes. That should spark flight out of shorter-dated Japanese government bonds (JGB), bringing relief to longer maturities, they say.

“It’s hard to see how 3% makes sense here,” said Ales Koutny, head of international rates at Vanguard, which has $1.8 trillion in actively managed funds. “We still plan to keep adding JGBs in the long end if the 30-year yield comes back towards 3%”

JGB 30 year yield

That view appears to be shared by others in the market. A sale of 30—year debt on Tuesday drew solid demand as the higher yields attracted buyers. Yields fell after the auction, then bounced back Thursday to 2.98%.
