OTTAWA – Canada’s annual inflation rate accelerated more than expected to 2% in October as gas prices fell less than the previous month, data showed on Tuesday, shrinking market bets for a bigger rate cut next month. Analysts polled by Reuters had forecast the inflation rate would speed up to 1.9% from 1.6% in September. In August, the annual rate was 2%. It was the first pick-up in the annual inflation rate since May. The central bank forecasts consumer price inflation to be 2.5% this year and 2.2% next year. …This was the last inflation data to be released ahead of the Bank of Canada’s interest rate announcement on Dec. 11, and currency markets now see around a 28% chance of a 50 basis point rate cut, down from 37% before the CPI data release.
