LONDON, June 21 (Reuters) - Sterling rebounded from a two-month low on Wednesday, briefly trading back above $1.27, after Bank of England Chief Economist Andy Haldane signalled he would weigh in behind a rise in interest rates in the second half of this year.
The pound had earlier sunk beneath $1.26 for the first time since mid-April as investors worried about Prime Minister Theresa May struggling to find the support she needs for her government, which lost its parliamentary majority in elections just under two weeks ago.
But it reversed those falls as the chief economist’s speech was published, trading up as much as 0.6 percent on the day to reach $1.2710, before easing back to $1.2666 by 1545 GMT. That still left it almost a cent higher than its earlier trough.
Against the euro, the pound was up 0.2 percent at 87.98 pence.
Haldane’s comments ran contrary to those of Governor Mark Carney, who had driven the pound lower on Tuesday by saying “now was not the time” to begin to raise rates.
Bets on a rate hike within the next year surged. Short sterling contracts for December reversed all of their gains since Carney’s speech, showing markets pricing in a greater than 50 percent chance of the Bank raising rates by then.
British gilt futures also shed around 25 ticks and government bond yields hit session highs.
“Here are some hawkish comments that are causing the market to price a greater probability of tightening, and sterling is responding to that,” said Barclays currency strategist Hamish Pepper, in London.
“There was a period of time in which it was all about politics for the currency – how big the political risk premium should be and so on – but for a while now we’ve been trading more like a normal currency, where data surprises and central bank rhetoric drives the normal kinds of reactions.”
The UK’s blue chip FTSE 100, which tends to fall as sterling rises because most of its multinational constituents earn in foreign currencies, hit a session low after the comments and was last down 0.3 pct.
The Queen’s Speech, which featured a promise from the prime minister to listen more closely to businesses’ concerns about Britain leaving the European Union, appeared to have little impact on the currency, which has fallen around 15 percent against the dollar since the vote for Brexit a year ago.
At a time of unprecedented political uncertainty, May is under increasing pressure to secure a deal with Northern Ireland’s Democratic Unionist Party (DUP) to prop up her government after nearly two weeks of talks.
“The only situation where I could see massive downside (for sterling) materialising is if the government collapses or Labour (the left-wing opposition party) gets the chance to form a government,” said Stephen Gallo, head of European FX strategy with Bank of Montreal in London.
