TOKYO: The Bank of Japan kept ultra-low interest rates and vowed to hold them there to support economic growth as it bucked a global tide of monetary tightening by central banks fighting to rein in soaring inflation.

BoJ governor Haruhiko Kuroda stressed the need to keep monetary policy ultra-loose for the foreseeable future with Japan’s economic recovery still fragile and wage growth not accelerating enough to make recent inflation sustainable.

“There’s absolutely no change to our stance of maintaining easy monetary policy for the time being. We won’t be raising interest rates for some time,” Kuroda told a briefing.

The BoJ’s decision came after the US Federal Reserve delivered its third straight rate increase of 75 basis points on Wednesday and signalled more hikes, underscoring its resolve not to let up in its battle against inflation.

The policy divergence pushed the yen to a fresh 24-year low and past the closely watched 145 to the dollar level, highlighting the dilemma Tokyo faces in trying to support the wobbly economy with ultra-low rates without accelerating unwelcome yen declines that inflate the cost of imports.

Shortly after the decision, Japan’s top currency diplomat said authorities would not tolerate excessive swings in the yen, a warning that comes a week after officials delivered their firmest indication yet that they would intervene in the market if needed.

“The BoJ was aware that an announcement like this should surely prompt a weak yen beyond 145 per dollar,” said Hiroaki Muto, an economist at Sumitomo Life Insurance.

“It’s clear that 145 yen wasn’t Kuroda’s line-in-the-sand.”

As widely expected, the BoJ kept unchanged its minus 0.1% target for short-term interest rates, and 0% for the 10-year government bond yield.

The unanimous decision came after a board reshuffle that brought in two newcomers in July, one of whom replaced a dovish member who consistently dissented to keeping policy steady. The vote count suggests the two members likely won’t rock the boat on monetary policy decisions for the time being.

The central bank also decided to phase out a pandemic-relief loan scheme and instead expand a liquidity operation targeting a broader range of corporate funding needs.

“The BoJ expects short-and long-term policy interest rates to remain at their present or lower levels,” the central bank said in a statement announcing the rate decision, making no change to its dovish guidance.

The yen dropped to 145.405 per dollar immediately after the BoJ’s announcement but then sharply swung back to around 144.50.

“There are cases where we could conduct stealth intervention,” Japan’s top currency diplomat Masato Kanda told reporters. “We haven’t intervened yet, but we’re ready to take action any time.”

The BoJ remains an outlier among a global wave of central banks withdrawing stimulus to battle soaring inflation, and will likely become the last major monetary authority in the world with a negative policy rate.

Japan’s core consumer inflation quickened to 2.8% in August, exceeding the BoJ’s 2% target for a fifth straight month, as price pressure from raw materials and yen fall broadened.

But Kuroda has ruled out the chance of a near-term withdrawal of stimulus on the view that wages need to rise more to sustainably achieve his 2% inflation target.

Kuroda’s dovish message has worked to weaken the yen, contradicting the government’s efforts to slow the currency’s decline through verbal threats of yen-buying intervention.
