TOKYO, May 27 (Reuters) – The Bank of Japan saw net income fall in fiscal 2025 as rising interest rates boosted payments made on ​excess reserves parked with the central bank, its ‌earnings data showed on Wednesday.

Since exiting a decade-long, massive stimulus programme in 2024, the central bank has raised its short-term policy rate several times, including in December to 0.75% from 0.5%.

The BOJ ‌thus ​pays 0.75% interest on the excess ⁠reserves financial institutions park ⁠with the central bank under a programme aimed at controlling money market rates around its policy rate.

The BOJ spent 2.7 trillion yen ($16.95 billion) on such interest payments ​in the fiscal year ending in March, much higher than the previous year’s 1.3 trillion yen and ⁠exceeding the 2.5 trillion yen interest ⁠it earned from its government bond holdings, ​the data showed.

It was the first time the BOJ’s interest ​payment on reserves exceeded the amount of interest ‌earned from its bond holdings, highlighting the cost of normalising monetary policy.

As a result, the BOJ saw net income shrink to 1.9 trillion yen in fiscal 2025 from ⁠2.3 trillion yen in the previous year, the data showed.

Aside from raising its short-term policy rate, the BOJ has been slowing ⁠bond purchases to ‌scale back its massive balance sheet ⁠as part of its policy normalisation efforts.

Due ​in part ‌to shrinking government bond holdings, the BOJ’s ​total asset ⁠balance fell 9.1% as of the end of fiscal 2025 from a year earlier, the data showed. Japan’s fiscal year runs from April to March of the following year.
