TORONTO, Oct 28 (Reuters) - The Canadian dollar rose by a cent against its U.S. counterpart on Thursday as the greenback slid amid growing uncertainty about the size of the U.S. Federal Reserve's monetary easing program, expected next week.
The U.S. currency surrendered gains from the last two days, as U.S. Treasury yields fell, making them less attractive, and easing demand for the dollars to buy them.
A recent move to trim extreme short dollar positions, amid speculation the Federal Reserve will announce plans to buy more assets next week, also slowed. [FRX/]
The Canadian dollar CAD=D4 touched a high of C$1.0181 to the U.S. dollar, or 98.22 U.S. cents, up sharply from Wednesday's close at C$1.0287 to the U.S. dollar, or 97.21 U.S. cents. At 12:05 p.m. (1605 GMT), it stood at C$1.0193 to the U.S. dollar, or 98.11 U.S. cents.
John Clinkard, chief economist at Deutsche Bank Canada, said the Canadian dollar's move was based on the broader "U.S. dollar story."
"We're looking at the potential risk of inflation in the U.S. and that is something that investors are concerned about," he said.
"When you debase a currency you're basically increasing the supply of money, and that is creating an inflationary threat.
The New York Federal Reserve has surveyed bond dealers and investors over the size and impact of a quantitative easing program in the United States, with scenarios ranging from zero up to $1 trillion, Bloomberg news reported on Thursday, citing a copy of the survey. [ID:nLDE69R15M]
A Reuters poll showed Wall Street analysts expect the Fed to buy between $80 billion and $100 billion worth of assets per month under a new program widely expected to be unveiled on Nov. 3. [FED/R]
"There's going to be massive disappointment if there's no quantitative easing next week," said Firas Askari, head of foreign exchange trading at BMO Capital Markets.
"There will be a significant (U.S.) dollar rally but there will be carnage in equity markets."
Askari said he sees the next buying opportunity for the Canadian dollar at resistance levels of C$1.0344-45 to the U.S. dollar, close to the 100-day and 200-day moving averages.
He said near-term support for the greenback lies at C$1.0190.
Canadian government bond prices were flat to higher, tracking U.S. Treasuries, but the market remained choppy as investors recalibrated U.S. easing expectations. [US/]
