Deep Tide TechFlow news, on December 5th, the trillion-dollar asset management giant Vanguard Group issued a warning that the market has severely underestimated Japan's neutral interest rate level. The group's global interest rate chief, Harlam, stated that the Bank of Japan needs higher interest rates than the market expects to effectively curb inflation and anticipates that the central bank will continue to raise rates at the meeting on December 19th. Currently, Japan's policy interest rate is 0.5%, while the neutral rate is estimated to be between 1% and 2.5%. Vanguard Group advises investors to underweight Japanese short-term government bonds, believing that underweighting Japanese bonds on the short end of the yield curve is the correct strategy to avoid risk.
