Japan's Bond Auction Tests BOJ Hike Bets and 3% Yield Threshold

Japan's sale of 10-year government bonds on Tuesday is being closely watched as investors worry about the threshold for benchmark yields and potential policy tightening. The yield touched 2.965% on Tuesday, its highest in three decades, ahead of the BOJ's September 18 decision. According to Bloomberg's Markets Live strategist Mark Cranfield, the auction was already facing a difficult backdrop even before Treasury yields jumped to a 19-month high.

The auction outcome is due at 12:35 p.m. in Tokyo, and investors will be scrutinizing demand metrics such as the bid-to-cover ratio, which was 2.56 at last month's 10-year sale. BOJ Deputy Governor Ryozo Himino said that an increase this month remains on the table, with a roughly 90% probability of a September hike reflected in overnight index swaps.

NHK reported that US Treasury Secretary Scott Bessent told Finance Minister Satsuki Katayama and BOJ Governor Kazuo Ueda that raising interest rates should be Japan's next step. Investors will also be watching Thursday's 30-year JGB offering as concerns about Prime Minister Takaichi's fiscal stance pressure super-long debt.
