Bank of Japan sticks to ultra-loose monetary policy

The announcement prompted the Japanese currency to sink to around 140.73 yen per dollar, from around 140.20 yen earlier.

The US Federal Reserve on Wednesday decided against lifting interest rates, as expected, but signalled plans for additional increases.

The euro also got a boost after the European Central Bank raised interest rates to a 22-year high.

Katsutoshi Inadome, senior strategist at SuMi TRUST, said ahead of Friday's decision there was no reason to expect Ueda would do anything other than continue with the ultra-easy monetary policies in the short term.

"We believe the BoJ will maintain its current accommodative monetary policy, as its inflation forecast for 2024 is still above its two-percent target," he wrote in a commentary.

"Given uncertainty about price increases next year, the BoJ will stay vigilant and avoid making hasty changes to the policy in the foreseeable future."

In April, the bank announced a broad review of its "non-traditional" attempts to banish the deflation that has plagued Japan since the 1990s, following the bubble era.

Moving away from monetary easing will be a tricky balancing act for Ueda, who faces pressure to normalise policy while minimising any shock to the economy.

In the January-March quarter, Japan's economy expanded 0.7 percent, up from an initial estimate of 0.4 percent, government data showed earlier this month.

A recovery in inbound tourism and household spending after pandemic border restrictions were lifted helped the world's third-largest economy, analysts said at the time.
