The Canadian dollar strengthened against the greenback on Thursday, recovering from a nearly seven-week low earlier in the day after a senior Bank of Canada official said the central bank had discussed the pace at which it could raise interest rates.

On Wednesday, the Bank of Canada left its policy rate on hold at 1.50 per cent.

The central bank discussed whether the gradual approach to raising rates that it has been taking over the past year remained appropriate, Bank of Canada Senior Deputy Governor Carolyn Wilkins said in a speech.

Wilkins indicated the central bank may be forced to raise interest rates if talks to renegotiate the North American Free Trade Agreement fail, saying protectionist measures could spur inflation.

“On balance, a shift to a faster pace of rate hikes seems more likely than any kind of pause,” said Adam Button, a currency analyst at ForexLive.

At 3:12 p.m. (1912 GMT), the Canadian dollar was trading 0.3 per cent higher at $1.3139 to the greenback, or 76.11 U.S. cents.

The currency’s strongest level of the session was $1.3128, while it touched its weakest since July 20 at $1.3226.

The loonie had been pressured by the prospect of an escalation in a trade dispute between the United States and China, with U.S. President Donald Trump gearing up to impose tariffs on $200 billion in Chinese goods and Beijing certain to retaliate against any measures.

Canada exports many commodities and runs a current account deficit, so its economy could be hurt if the global flow of trade or capital slows.

“Canadian dollar traders are trying to balance the positive risks of a NAFTA deal and the negative risks of a China trade war,” Button said.
