A Canadian dollar or loonJonathan Hayward/The Canadian Press
The Canadian dollar ended essentially flat Friday, as the conflict in Iraq intensified and triggered fears that oil supplies from the Middle Eastern country may be at risk.
The loonie closed down 0.01 of a cent at 92.11 cents (U.S.).
In Iraq, Islamic militants vowed to march on Baghdad after pushing deep into parts of the country's Sunni heartland that was previously controlled by U.S. forces.
U.S. officials have ruled out putting troops back on the ground, despite this being the biggest threat to the country's stability since the Americans withdrew at the end of 2011.
On Friday, a representative for Iraq's top Shiite cleric urged citizens to take up arms and defend their country from the militants.
Mosul, one of the two captured cities, lies in an area that is a major gateway for Iraqi oil. While the loss of the city has no immediate effect on oil exports, now at over three million barrels a day, it adds to concerns over security and the country's plans to expand oil production.
The upheaval comes after the Organization for the Petroleum Exporting Countries met in Vienna this week and said it will maintain its current output of 30 million barrels a day. Iraq is OPEC's No. 2 oil producer.
The July crude contract advanced 38 cents to $106.91 a barrel.
"Today, the focus is on oil markets, where prices have risen on the back of rising supply risk from developments in Iraq," wrote Camilla Sutton, chief foreign exchange strategist at Bank of Nova Scotia.
"However, the impact of high oil prices on [the loonie] are typically more powerful when they are high on the back of demand versus supply issues," Sutton said in a research note.
Meanwhile, investors were still digesting the latest announcement from the Bank of Canada.
In a semi-annual financial review Thursday, bank governor Stephen Poloz signalled that the central bank would likely keep interest rates on hold for the near future. Some analysts expect that date to be closer to the second half of 2015.
"[Poloz] has a fine balancing act between recognizing the shift in the fundamentals but highlighting that the underlying strength of the economy is still vulnerable and unbalanced," Sutton said. "For the [Canadian dollar], the core message is a zone of stability as the fundamentals have improved but interest rates are likely to remain on hold for an extended period of time."
In other commodities, August gold bullion added 10 cents to $1,274.10 an ounce, while July copper rose a penny to $3.03 a pound.
