The dollar steadied on Wednesday and risk appetite recovered somewhat, but euro-dollar volatility remained elevated as investors weighed up hawkish comments from the Federal Reserve and risks relating to the Omicron variant.
The dollar rose on Tuesday after U.S. Fed Chair Jerome Powell said that the risk of inflation had increased and signaled the central bank may accelerate its bond-buying taper at its meeting later this month.
At 1147 GMT, the dollar index was little changed overall on the day at 95.940. In November, it had its strongest month since June.
Global stock markets and riskier currencies recovered some of the previous session's losses as investors bet that the Omicron variant - which has prompted countries to impose new travel restrictions - would not derail the economic recovery.
But in currency markets, volatility remained elevated. One-month euro-dollar volatility gauges hit their highest so far this year on Monday.
ING strategists wrote in a client note that euro-dollar volatility has jumped as the Omicron variant is seen as positive for the euro (because it could slow the Fed's tightening), while Powell's remarks (suggesting inflation is the Fed's primary concern) are seen as negative for the euro.
"Both themes will be fed many fresh inputs over the next four weeks and thinning liquidity conditions point to bumpy conditions in FX markets," ING said.
The euro was down 0.1% on the day at $1.1322 at 1201 GMT .
On Tuesday, a warning from drugmaker Moderna that existing vaccines are unlikely to be as effective against the Omicron variant as they are against other strains, led to a surge of interest in safer assets.
BioNTech CEO Cautiously Positive on Omicron
Later, BioNTech's chief executive struck a cautiously positive note, saying the vaccine it makes in a partnership with Pfizer would likely offer strong protection against severe disease from Omicron.
Sterling, considered a risk currency, was up 0.2% at $1.33175, after fears about whether the vaccine will work against the Omicron variant saw it fall to its lowest level since December in the previous day.
The Australian and New Zealand dollars also made gains, carrying them up from one-year lows, after losses last week and on Tuesday. The Aussie was up 0.3% at $0.7149 and the kiwi was up 0.3% at $0.6842.
The Chinese yuan, a beacon of resilience in a turbulent few days, touched a six-month high of 6.3596 per dollar after better-than-expected manufacturing data from November.
In cryptocurrencies, bitcoin was up around 0.5% at $57,266.93.
