The loonie gave up all of Tuesday's gain of almost half a cent, closing down 0.45 of a cent to 96.02 cents US.
The latest word on interest rates from the Bank of Canada and the Monetary Policy Report represent the first policy announcement from the central bank's new governor, Stephen Poloz.
The Poloz influence was evident in the explanatory note to the rate announcement, which dropped the reference that interest rates are likely to remain unchanged for a period of time. Instead, the new governor made clearer that he intends to makeo no changes as long as considerable slack remains in the economy, inflation remains muted and household finances continue to improve.
"The forward-looking language was made somewhat more definitive than in previous iterations of the communique, tying the normalization of interest rates to specific economic factors such as household indebtedness, economic slack and muted inflation," said Royal Bank economist Francis Fong.
"While these factors have always been top of mind for the bank, they were made somewhat more explicit."
The Bank of Canada has kept its key rate at one per cent since September 2010.
The Canadian central bank's new outlook raises this year’s growth forecast to 1.8 per cent from the previously projected 1.5 expectation, that is almost entirely due to a stronger than anticipated first quarter.
The bank sees the economy expanding at a rate of 2.7 per cent in 2014 and 2015, little different from the April forecast of 2.8 per cent and 2.7 per cent growth in the two years.
The bank continues to anticipate that the Canadian economy won’t return to full capacity until mid-2015.
Traders also digested remarks from Federal Reserve chairman Ben Bernanke that the Fed could slow the pace of a key element of economic stimulus later this year if the economy strengthens. But Bernanke cautioned that the Fed wants to see substantial progress in the job market before scaling back its US$85 billion in monthly bond purchases.
Markets went through weeks of volatility after Bernanke first mentioned in late May that the Fed could start tapering its program of monthly purchases of US$85 billion of bonds later this year and wind it up by the middle of next year.
Investors feared Bernanke's comments meant the Fed was ready to let rates rise sooner and faster than they’d expected.
Since then, the Fed has tried to soothe nerves by stressing that the Fed won’t pull back on its stimulus unless there's clear evidence that the economy and the job market are improving as much as the Fed has forecast.
But the dollar has weakened and bond yields have risen ever since Bernanke mentioned the possibility of tapering. The benchmark U.S. 10-year Treasury has risen from about 1.6 per cent at the beginning of May to around 2.5 per cent.
Commodity prices were mixed with the August crude contract on the New York Mercantile Exchange up 48 cents to US$106.48 a barrel.
September copper on the Nymex dipped six cents to US$3.13 a pound. August gold bullion declined $12.90 to US$1,277.50 an ounce.
On the economic front, the Fed said in its latest regional survey that it sees the overall economy growing at a modest to moderate pace, although there is some reluctance to hire full-time workers. The Fed also said six districts reported faster growth in multi-family construction.
Other data showed U.S. builders started work on fewer homes and apartments in June. However, the slowdown wasn’t enough to suggest the housing recovery is faltering.
Developers began construction at a seasonally adjusted annual rate of 836,000 homes in June, nearly 10 per cent below May’s total of 928,000, which was revised higher.Suggest a correction
