Il Nuovo Postiglione - Bank of Japan sticks to ultra-loose monetary policy

The central bank has gone against the grain as its global peers hike interest rates to tackle inflation, pushing down the value of the yen against the dollar.

Officials had been widely expected to keep policies unchanged after the second two-day meeting under new Governor Kazuo Ueda, who took the helm in April.

They left the bank's negative interest rate in place and did not adjust the band in which rates for 10-year government bonds fluctuate, a scheme known as yield curve control.

The announcement prompted the Japanese currency to sink to around 140.75 yen per dollar, from around 140.20 yen earlier.

In contrast, the European Central Bank on Thursday raised interest rates to a 22-year high, boosting the euro, while also warning of persistent inflation and slower growth.

On Wednesday the US Federal Reserve decided against lifting rates, as expected, but signalled plans for additional increases as it assesses the impact of 10 straight hikes since early last year.

Shigeto Nagai of Oxford Economics said the Bank of Japan did not seem in a hurry to change its ways, "despite recent upside surprises both on the growth and inflation fronts".

"We believe that the BoJ will maintain the status quo for another year or so to assess whether the economy is on track to achieving two-percent inflation within Ueda's five-year term," he said.

A recovery in tourism and household spending helped the world's third-largest economy expand a better-than-expected 0.7 percent in the January-March quarter.

Inflation stood at 3.4 percent in April -- down from a January peak when consumer prices rose 4.2 percent on-year, the highest rate since 1981.

While inflation in Japan remains lower than the sky-high increases seen in the United States and elsewhere, it is above the central bank's two-percent target, which has been surpassed every month since April last year.

The BoJ argues that the price rises are fuelled by temporary factors, such as the war in Ukraine, and so has stuck to its loose policies in a bid to encourage sustained growth.

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.

But 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.

There had been speculation of a change of tack late last year when the bank widened the band in which it allows 10-year bonds to fluctuate but it has not moved since.

Ueda "will likely set a deadline to judge whether the economy is on track to meet the policy goal within his term so that he can take necessary actions", Nagai said, adding that such a decision point could arrive in mid-2024.
