(Updated with Aussie dlr levels after GDP data, fresh comments)
The U.S. dollar was largely steady on Wednesday, as traders avoided making big bets ahead of congressional testimony from Federal Reserve Chair Jerome Powell, as well as the European Central Bank rate decision and U.S. jobs data later this week.
In cryptocurrencies, bitcoin BTC= was slightly up but stayed below a record high reached in a volatile overnight session.
The absence of catalysts kept the dollar in a tight range, having slipped overnight on data that showed the U.S. services industry growth slowed a bit last month.
The February U.S. jobs report on Friday stands as a test for the rates outlook, with the potential to rock markets if it surprises to the upside.
Traders were also waiting on Fed Chair Powell's first day of testimony before Congress on the state of the U.S. economy, where he's expected to reinforce that the Fed will wait for more data before making any rate cuts.
The Fed chief may also echo comments that strong core inflation in January hasn't significantly changed the central bank's outlook, said Carol Kong, a currency strategist at the Commonwealth Bank of Australia.
"A reiteration of this message is unlikely to alter current market pricing for a June start to the FOMC’s rate cut cycle, and should therefore have limited impact on the USD."
Markets have priced in about a 60% chance of a rate cut in June, according to the CME FedWatch tool.
The dollar index =USD , which measures the greenback's strength against a basket of six currencies, hovered around 103.84.
The euro EUR=EBS edged down 0.1% to $1.0846 as traders braced for the ECB's interest rate decision later on Thursday.
The central bank is expected to leave rates at a record 4%, putting the focus on clues about when cuts may begin and updates to economic projections.
Charu Chanana, head of currency strategy at Saxo, said she doesn't expect the ECB to send a clear dovish message given that eurozone inflation dipped less than expected last month.
"Still, inflation prints are likely to be revised downwards, and this poses some downside risks for EUR, but it will remain a buy on dips given that the economy is stabilizing."
Business activity in the euro zone showed signs of recovery in February, according to a survey on Tuesday.
Sterling GBP=D3 was down 0.08% at $1.2696 ahead of the British budget announcement on Wednesday.
The Australian dollar AUD=D3 held around $0.6502 after gross domestic product data showed the economy grew a mere 0.2% in the fourth quarter, reinforcing the case for rate cuts.
The kiwi NZD=D3 slipped 0.1% to $0.6081. The dollar was mostly flat against the yen JPY=EBS at 150.04, after retreating overnight from last week's high of 150.85.
Markets are also keeping a close eye on the world's largest cryptocurrency, bitcoin BTC= , after it surged to a record high overnight before retreating sharply.
It was last up 0.15% at $63,414, taking a breather having rallied hard since October as investors poured money into U.S. spot exchange-traded crypto products and on the prospect that global interest rates may fall.
