U.S. dollar advances as markets brace for hefty Fed rate hike

LONDON/NEW YORK, Sept 19 (Reuters) - The dollar gained against major currencies on Monday, trading within narrow ranges ahead of a slew of central bank meetings this week led by the Federal Reserve, which is likely to deliver another hefty interest rate hike.

Trade was generally subdued, with markets in London and Tokyo closed for public holidays.

World stock markets remained on edge and the dollar maintained its firm tone, given expectations that the Fed would maintain its aggressive tightening path to contain uncomfortably high inflation.

"On a high level, the greenback is benefiting from a continued sell-off in global equities," said John Doyle, vice president of trading and dealing at Monex USA in Washington.

"With the Fed's decision pending, I think the dollar will continue to take its cues from overall risk sentiment. We do not think the Fed will hike 100 basis points this week, but the potential is still real," he added.

Fed funds futures have priced in a 79% chance of a 75-basis-point rate hike this week and a 21% probability of a 100-basis-point increase at the conclusion of the U.S. central bank's two-day policy meeting, according to Refinitiv data.

The dollar index , which measures the currency against six counterparts, was up 0.4% at 109.98, not far from 20-year high of 110.79 hit on Sept. 7.

This week is also smattered with holidays that could thin liquidity and result in sharper price moves, with Japan and Britain off on Monday, Australia on Thursday, and Japan again on Friday, among others.

In other currencies, the euro was 0.3% lower against the dollar at $0.9984 , sterling was 0.4% weaker at $1.1386 and within sight of Friday's 37-year lows, while the New Zealand and Australian dollars fell 0.8% and 0.5%, respectively.

The New Zealand dollar fell to its lowest level since May 2020 of US$0.5933, and was last at US$0.5937 .

The Canadian dollar fell to its lowest level in almost two years at C$1.3324 per U.S. dollar .

"The drop in oil has allowed a modest rally against commodity-based currencies such as the Canadian dollar," said Monex's Doyle.

The dollar was around 0.4% firmer at 143.50 yen , hovering beneath a strong resistance level at 145 that has been reinforced by Japanese policymakers' toughened talk of currency intervention.

The Bank of Japan is widely expected to stick with massive stimulus at its meeting on Wednesday and Thursday, keeping its ultra-loose policy in place. But a turning point in Japanese monetary policy may come sooner than has been thought, with the central bank recently dropping the word "temporary" for its description of elevated inflation. read more
