The dollar fell today but was still on track for its biggest annual gain since 2015, in the last trading day of a year dominated by Federal Reserve rate hikes and fears of a sharp slowdown in global growth.

Asian equities had risen earlier in the session after market sentiment on Wall Street got a boost from data showing rising US jobless claims, which suggested the Fed's interest rate hikes were lowering demand for labour.

With liquidity lower due to the Christmas and New Year holidays, the dollar index was down around 0.308% on the day at 103.650.

The US Federal Reserve has raised rates by a total of 425 basis points since March in an attempt to curb surging inflation.

As 2022 draws to a close, the dollar has gained around 8% against a basket of currencies - its biggest annual jump in seven years - but it has pared some gains in recent weeks as investors look for signs about when the Fed's rate-hiking cycle might end.

"I think everyone is struggling with the question of whether the big problem in 2023 will be weak growth or stubborn inflation," said Adam Button, chief currency analyst at ForexLive.

"If it's weak growth, the US dollar will fall. If it's high inflation, then the US dollar will rally," he added.

The euro was up 0.22% on the day to $1.0684, on track for a 6% annual loss versus the dollar, compared with last year's 7% drop.

A combination of weak euro zone growth, the war in Ukraine and the Fed's hawkishness has put the euro under pressure this year.

The British pound was last up 0.21% at $1.2077, set for a 10.7% annual drop.

The Australian dollar, seen as a liquid proxy for risk appetite, was up 0.12% on the day at $0.679, but on track for a 6.5% drop on the year overall.

China's offshore yuan was down 0.91% against the U.S. dollar at $6.9092. It was set for an 8.6% annual drop, hurt by dollar strength and a domestic economic slowdown.

Optimism about China's reopening after three years of strict Covid-19 curbs has been tempered by surging infections which threaten more economic disruptions.

Jan Von Gerich, chief analyst at Nordea, said China's reopening "will be a source of volatility."

"But when we get past that, when we really get to the really positive economic impact, I think it should boost risk appetite globally," he said.

The US dollar was down around 0.91% against the Japanese yen, at 131.820.

The Bank of Japan's ultra-dovish stance has seen the dollar gain 14.5% versus the yen so far this year, in the yen's worst performance since 2013.

But the Bank of Japan's surprise decision to tweak its bond yield control programme saw the yen jump to a four-month high against the U.S. dollar earlier in December.

The Swiss franc was steady versus the dollar, at 0.92250.

The Swiss National Bank increased the amount of the Swiss currency it sold in the third quarter of 2022, the central bank said today, indicating that its focus has switched from stemming the franc's strength to fighting inflation.

In cryptocurrencies, bitcoin last fell 1.13% to $16,405, down more than 64% so far in 2022.
