The Canadian dollar was off slightly following a sharp runup after the U.S. Federal Reserve unveiled a third round of economic stimulus to help a weak economy.
The loonie was down 0.07 of a cent (U.S.) to 103.2 cents after the U.S. central bank said it will spend $40 billion a month on a new round of bond purchases and will continue to do so until the job market shows substantial improvement.
The money will be spent on mortgage backed securities to keep interest rates low, encourage lending and support the slow recovery of the housing sector.
The currency had been up more than half a cent earlier Friday morning but moved lower amid soft manufacturing data while traders took some profits from a substantial gain.
The loonie had surged well over 2 1/2 cents over the last week as the European Central Bank announced a plan to purchase government bonds in order to keep euro zone borrowing costs under control and speculation mounted the Fed would act to support a slowing economy.
"Central bank policy, namely by the ECB and Fed, have put significant downward pressure on the U.S. dollar," said Scotia Capital chief currency strategist Camilla Sutton.
"The looming threat of (further stimulus moves), without substantial improvement in the labour force, is likely to put additional downward pressure on the U.S. dollar and has made employment releases a key component of USD valuation."
On the economic front, there was data showing slowing Canadian manufacturing shipments and U.S. retail sales.
Statistics Canada said that manufacturing sales fell 1.5 per cent to $48.3-billion (Canadian) in July, the third decrease in five months. The agency said that declines in transportation equipment were largely responsible for the overall drop.
And in the U.S., the Commerce Department said retail sales increased a seasonally adjusted 0.9 per cent. Gas station sales jumped 5.5 per cent, the most in nearly three years and a reflection of sharp price increases. Demand for autos increased 1.7 per cent.
Outside those categories, sales rose only 0.1 per cent.
Commodities rose sharply as the Fed program raised demand prospects for oil and metals.
Geopolitical worries also drove oil prices higher as a wave of anti-American protests in the Mideast raised supply concerns.
Protesters stormed the U.S. Embassy compound in Yemen's capital Thursday. Ongoing clashes have been taking place around the U.S. mission in Cairo, and the U.S. ambassador to Libya was killed Tuesday.
The October crude contract on the New York Mercantile Exchange gained $1.11 (U.S.) to $99.42.
The rally in copper prices continued with the December contract up 12 cents (U.S.) to $3.83 a pound. Copper, viewed as an economic barometer because it is used in so many industries, has surged about 18 cents this past week.
Bullion gained $3.70 (U.S.) to $1,775.80 an ounce following a jump of almost $40 on Thursday as the Fed program raised inflation concerns.
