Bank of Japan Expected to Raise Rate to 1.25% in Fastest Hike of Cycle

The expected move is 25 basis points. A basis point is 0.01 percentage points, so 25 basis points equals one-quarter of a point. The Journal, in a Sept. 15 piece titled 'Bank of Japan Set to Deliver Fastest Hike of Cycle as Pressure Mounts', described it as the fastest increase of the current cycle.

A Sept. 11 preview had already flagged a Friday increase as widely expected, citing hawkish remarks from officials, meaning comments leaning toward higher rates, and firm economic data. Wall Street Journal Policy signals hardened first. Market pricing followed, much like runners lining up after the starting gun.

The starting point is on the record. Minutes for the Jan. 22-23, March 18-19 and April 27-28 meetings each state the Bank will encourage the uncollateralized overnight call rate, the rate banks charge each other for overnight loans without collateral, to remain at around 1.0 percent. The June 15-16 minutes put the interest rate applied to the complementary deposit facility, the rate paid on reserves banks park at the Bank, at 1.0 percent per annum, while the Dec. 18-19, 2025 minutes put the basic discount rate and basic loan rate at 1.0 percent per annum. Bank of Japan The January discussion included a policy proposal by Takata Hajime, with Takata listed as a vote for the proposal in March and April.

In currency markets, the yen climbed to a nearly seven-month high of 152.89 per dollar in the week before Sept. 16. Reuters Positioning stayed volatile into the central bank decisions. On Sept. 14, the dollar rose 0.5% to 154.355 yen, up from an almost seven-month low below 153 the prior week. Reuters

On Sept. 7, the dollar fell to as low as 154.05 yen, its weakest level since February. In the week to Sept. 8, the yen rose 4.5% to near a seven-month peak. The yen was still higher than its level several months earlier, but off its intraday extreme heading into the meetings.

The Federal Reserve moved first. At its Sept. 15-16 meeting, the Federal Open Market Committee decided to raise the target range for the federal funds rate, the Fed's main policy rate, by 1/4 percentage point to 3-3/4 to 4 percent. Federal Reserve The Board of Governors voted unanimously to raise the interest rate paid on reserve balances to 3.90 percent. Federal Reserve

The Fed issued an FOMC statement and an Implementation Note on Sept. 16. The meeting was associated with a Summary of Economic Projections and followed by a press conference, with transcript available. Minutes of regularly scheduled meetings are released three weeks after the policy decision, a lag that put the July 28-29 minutes on Aug. 19.

The broader context here is pace and divergence. A 25-basis-point step from a 1.0% call-rate anchor would shorten the interval between moves rather than change the debate about the end point. For money markets, the question is pass-through to the complementary deposit facility, trading ranges around the overnight call rate, and how firmly short-term borrowing costs re-price.

In my view, the risk is two-sided in a way that puts more weight on words than on the rate move itself. A Fed hike alongside a BOJ hike keeps the gap between U.S. and Japanese rates wide but reduces the push in one direction. If the BOJ delivers and keeps a steady message on timing, yen strength into the decision could pause. If it surprises on timing or tone, the 152.89 to 154.35 range of the past week shows where trading positions were building. The minutes trail from January to June still matters. It shows a committee that held 1.0% while internal debate, including Takata's proposal, stayed live.
