Canadian Dollar Falls to One-Month Low as Fed Rate Hike Boosts Greenback

The Canadian dollar posted a notable weekly loss against its U.S. counterpart, with the USD/CAD exchange rate climbing to 1.4005, its highest level in a month. The move was primarily driven by diverging central bank policies after the U.S. Federal Reserve implemented another interest rate hike, increasing the allure of the greenback.

Policy Divergence Drives Weakness

The primary catalyst for the Canadian dollar's underperformance was the U.S. Federal Reserve's decision on September 16 to raise its benchmark interest rate to 4.00%. According to a report from Investing.com, this move widened the interest rate differential between the U.S. and Canada, making U.S. dollar-denominated assets more attractive to investors.

In contrast, Canadian economic data gave the Bank of Canada little incentive to tighten its own policy. While August inflation remained above target at 3%, it was not sufficient to prompt a more hawkish stance, leaving the loonie vulnerable to capital flows favoring the higher-yielding U.S. dollar.

Performance Across Major Pairs

The Canadian dollar's weakness was most pronounced against the greenback, but it also lost ground against other major currencies. The loonie's performance for the week ending September 18 highlights the impact of global macroeconomic forces.

• USD/CAD: The pair rose from a close of 1.3865 on September 11 to 1.4005, representing a 1.0% weekly decline for the Canadian dollar.
• CAD/JPY: While the CAD/JPY pair rose 1.6%, this reflected significant weakness in the Japanese yen rather than strength in the loonie.
• Other Currencies: The Canadian dollar also weakened against the Swiss franc and British pound, while holding relatively steady against the euro and the Australian dollar.

Commodity Support Overwhelmed

Typically, the commodity-linked Canadian dollar finds support from rising energy prices. However, despite Brent crude oil trading above $107 per barrel, this tailwind was negated by broader market dynamics.

Overwhelming U.S. dollar strength, combined with a general risk-averse sentiment among investors, offset the positive influence of high oil prices. This demonstrates how central bank policy and global risk appetite can overpower fundamental commodity relationships in foreign exchange markets.
