The US dollar continued to recover on Tuesday from a recent bout of selling, supported by comments from a US Federal Reserve official suggesting that the bank has not ruled out an interest rate hike as soon as next month.

In afternoon trading in London, the dollar index, which measures the buck's strength against a basked of other major currencies, was up around 0.34 per cent on the day at 100.2, having earlier risen as much as 0.6 per cent.

The dollar was also around 0.45 per cent higher against the euro, although it was 0.2 per cent down against sterling.

Patrick Harker, the president of the Federal Reserve Bank of Philadelphia, said in a speech on Monday that action “is on the table” for March, but that it depends on economic data between now and then.

He said that last week’s jobs report, coupled with strong growth figures, was an encouraging sign of the economy’s resilience.

According to official data published on Friday, total US non-farm payrolls rose by 227,000 in January, much higher than the 175,000 expected by economists.

The unemployment rate, however, ticked up to 4.8 per cent from 4.7 per cent due to an increase in the participation rate to 62.9 per cent from 62.7 per cent the previous month.

The Fed is due to hold its next interest rate meeting on 14 or 15 March and Mr Harker is the second official of the bank to indicate in recent weeks that a rate increase could be announced then.

John Williams, his colleague from San Francisco said last week that he thinks it is possible that a move is announced at the March meeting.

Higher interest rates tend to support a country’s currency and during morning trading in London the dollar was trading up against both the euro and the pound, despite having last week hit its lowest level against a basket of currencies since mid-November.

“Traders in the City seem to have woken up to the prospect of the Fed tightening interest rates quicker than they’d thought,” Neil Wilson, a senior market analyst at ETX Capital, said. He said that Mr Harker’s comments had “thrown the cat among the doves a bit as the last FOMC meeting suggested the Fed was not likely to raise rates until the summer”.
