OTTAWA--The spotlight will fall on the Bank of Canada's inflation outlook when it issues its latest interest-rate decision Wednesday.

A long spell of inflation of less than 2% prompted the central bank to abandon long-standing signals of potential rate increases last autumn and to adopt a neutral rate bias. But with consumer prices trending higher, markets are watching its inflation narrative closely, given that the central bank sets monetary policy to achieve a 2% inflation target.

The trend in prices marks a significant change from the start of the year, when the Canadian central bank and those in the U.S. and other major economies were fretting about low inflation.

In Canada, the consumer-price index grew 2% year-over-year in April and accelerated to 2.3% in May, the fastest pace in more than two years. Both the headline and core inflation measures are tracking higher than the central bank's forecasts in April, which will make it harder to maintain the assertion from its June 4 rate statement that downside risks to the inflation outlook are "as important as before," economists said.

All 12 primary dealers of government securities surveyed by The Wall Street Journal expect the Bank of Canada to hold its benchmark interest rate at 1% on Wednesday, and through the end of the year. The rate has stood at that low level since September 2010. The unanimous view is that the next move will be a rate increase, with projected time lines among economists ranging from the first quarter of 2015 to early 2016.

A majority of economists expects the Bank of Canada to tweak its language about the inflation outlook in Wednesday's statement to reflect higher prices, but most say its view will be balanced by growth concerns after Canada's gross domestic product fell short of forecasts in the first quarter, growing just 1.2% in annualized terms. And a dismal jobs report for June will bolster the central bank's case that slack in the economy will keep the lid on inflationary pressures, they said. The economy unexpectedly lost 9,400 jobs last month, and the jobless rate climbed to 7.1% from 7%.

The central bank will likely leave out the fact that the Canadian dollar plays a major role in its characterization of the inflation and growth outlook. The currency has firmed in recent sessions, fueled partly by expectations of a less-dovish take on inflation. But this could jeopardize the exports recovery that Canadian policy makers hope will help drive growth as debt-ridden consumers cut back on spending.

A weaker currency makes exports less expensive abroad and therefore more competitive, so the Bank of Canada is likely to be careful not to sound hawkish and risk the Canadian dollar taking flight, observers said.

"The bottom line is, the Bank of Canada doesn't want to say anything that would encourage a further rally in the Canadian dollar. They will bend over backwards to maintain a neutral stance as long as possible," according to CIBC World Markets chief economist Avery Shenfeld.

But Stefane Marion, chief economist of National Bank of Canada, believes the Canadian dollar has already priced in strong inflation figures, so there is no risk of a major move if, as he expects, the central bank tones down low inflation concerns and effectively shifts to a tightening bias on rates.

"I don't think they will guide toward rate hikes, but it's an overstretch to guide toward a rate cut," Mr. Marion said, adding that the Bank of Canada will probably say that the overnight rate will remain at 1% for an extended period.
