Japan 40-Year Bonds Trade First Time in Four Days Before Auction

Japan’s 40-year bonds traded for the first time in four days at the nation’s largest inter-dealer debt broker before the Ministry of Finance auctions 30-year debt on Thursday.

The last time the country’s longest-dated debt stayed untraded for more than three days was in July, when yields were almost four times higher, according to data from Japan Bond Trading Co. in Tokyo. Yields on bonds with maturities as long as 10 years have gone negative since the Bank of Japan announced in January that it would start charging lenders on some of their excess reserves held with the central bank. Yields on about 70 percent of all Japanese government bonds are below zero.
