TOKYO — Japanese financial authorities carried out rate checks with commercial foreign exchange desks, the Nikkei newspaper reported, triggering a swift rebound in the yen after the currency weakened sharply despite a Bank of Japan (BOJ) interest rate increase.
The BOJ raised its benchmark policy rate by 25 basis points to 1.25%—taking borrowing costs to a 31-year high. However, the initial market response saw the yen slide toward 157 per dollar as FX traders focused on persisting interest rate differentials between Japan and global central banks. Reports of rate checks—a traditional operational precursor to direct government market intervention—prompted traders to rapidly unwind short-yen positions out of caution.
Key Takeaways from the Market Development
Rate Checks as Warning Signal: A "rate check" involves central bank or Ministry of Finance officials phoning market makers to ask for price quotes, signaling to traders that authorities are actively preparing to buy yen with official reserves if volatile moves continue.
BOJ Policy Milestone: The BOJ raised key short-term borrowing costs to 1.25%, marking the highest borrowing rate for Japan since April 1995 as policymakers respond to persistent underlying inflation and currency depreciation.
Yield Differentials Persist: Despite the hawkish rate decision, the yen initially tumbled as high U.S. yields continue to attract capital, leading Japanese officials to deploy verbal and operational warnings to curb rapid currency depreciation.
