Asian stocks mostly rose on Friday in line with a rally on Wall Street as a tumble in oil prices eased inflation concerns, while the yen dropped against the dollar even after the Bank of Japan hiked interest rates to a three-decade high.

The US Federal Reserve’s lift in borrowing costs this week provided some relief to traders concerned that policymakers were not moving quick enough to address a spike in inflation that could deal a blow to the world’s top economy.

That has been helped by news that Saudi Arabia was moving to restore within days about half of crude shipments disrupted by the stoppage of its East-West pipeline to the Red Sea.

The conduit, even more important since the effective closure of the Strait of Hormuz by Iran, was shut last week after being targeted by Yemen’s Iran-backed Houthis.

Crude prices, which had soared around a fifth in September, have fallen sharply over the past three days, with West Texas Intermediate dipping below $100. Brent and WTI lost more than 2% Friday.

The surge in oil this month has been among the main catalysts for rising inflation since the United States and Israel began their war on Iran at the end of February.

And the latest fall-off provided some much-needed support to stocks.

Seoul, Tokyo, Hong Kong, Shanghai, Taipei, Mumbai and Bangkok all advanced, although there were losses in Singapore, Wellington, Jakarta and Manila. Sydney was barely moved.

London, Paris and Frankfurt dipped.

The latest moves in oil and the Fed’s action reassured investors and kept the 10-year US Treasury bond yield — a key indicator of borrowing costs throughout the world’s biggest economy — back below 5%.

Japan’s Nikkei was also helped by a drop in the yen against the dollar that came in the wake of the BoJ’s well-telegraphed decision to lift rates to their highest level since 1995.

Pressure has increased on officials to further tighten monetary policy as a spike in oil prices caused by the Middle East crisis — which shows little sign of ending anytime soon — is expected to keep putting a floor under inflation.

“Given that underlying CPI inflation has been approaching 2% and financial conditions have been accommodative, the bank will continue to raise the policy interest rate,” the BoJ said on its website.

But the yen slipped to more than 157 to the greenback, compared with around 156 earlier.

Stephen Innes at Quintex Intel suggested traders were jolted by the fact that the hike was not unanimous, passing by a 7-2 majority.

“For a market looking for evidence that the BoJ could shorten the distance between hikes, those dissents mattered,” he wrote.

“Traders were looking for signs that the Bank could move faster from here, yet two members were already arguing that even today’s move had come too soon.”

Focus will now turn to Governor Kazuo Ueda’s news conference due later in the day.

“Attention should fall on the forward swaps curve and the Bank’s guidance around the pace and urgency of further tightening,” wrote Chris Weston at Pepperstone.

“The market will be looking for confirmation that further normalisation remains firmly on the table, while assessing whether the Bank sees any urgency to move again.”
