Canadian dollar weakens against major currencies in the week ending September 18

The Canadian dollar's notable underperformance in the week ending September 18 was a complex interplay of global monetary policy and market sentiment, rather than a reflection of its usual commodity-driven strength. The currency, often referred to as the 'loonie,' recorded significant losses against most major counterparts, with the USD/CAD pair surging to 1.4005, marking its highest level in a month. This movement underscored a period where the Canadian dollar struggled to find its footing amidst a challenging global financial landscape.

Fed rate hike

The primary catalyst for the Canadian dollar's depreciation was the U.S. Federal Reserve's decision to raise interest rates to 4.00% on September 16. This move by the Fed intensified the yield gap between U.S. and Canadian assets, making the U.S. dollar significantly more attractive to investors seeking higher returns. The hawkish stance from the Fed created a strong tailwind for the greenback, drawing capital away from other currencies, including the CAD, and contributing to its overall weakness across the board.

This aggressive monetary tightening by the U.S. central bank signaled a diverging path compared to other global central banks, which either maintained a more cautious approach or had less impactful policy adjustments. The resulting strength of the U.S. dollar exerted considerable pressure on the Canadian dollar, making it the most significant factor in the CAD's weekly decline. The market's reaction demonstrated how powerful central bank policy can be in dictating currency movements, even for those typically influenced by commodity markets.

Oil’s limited support

Despite Brent crude oil prices trading above $107 per barrel, a level that would typically provide substantial support to the Canadian dollar, its impact was notably muted during this period. The article highlights that global risk aversion and the overwhelming strength of the U.S. dollar effectively offset any potential commodity tailwind for the CAD. This situation illustrates a scenario where fundamental economic drivers, such as high oil prices, were overshadowed by broader market dynamics and investor sentiment.

Normally, Canada's status as a major oil exporter means its currency benefits from rising crude prices, as it implies increased export revenues and a stronger economic outlook. However, the prevailing risk-off sentiment, coupled with the allure of higher U.S. yields, meant that investors prioritized safe-haven assets and yield differentials over commodity-linked currency plays. This limited support from oil underscores the complexity of currency markets, where multiple factors can converge to dictate performance, sometimes overriding traditional correlations.

Canadian inflation

Another contributing factor to the Canadian dollar's vulnerability was the state of domestic inflation. August inflation in Canada remained stubbornly at 3%, which is above the Bank of Canada's target. However, this level was not deemed sufficient to trigger an immediate monetary policy response from the Bank of Canada, such as a rate hike. The central bank's inaction left the Canadian dollar exposed to global financial flows and external pressures.

The lack of a decisive move from the Bank of Canada meant that the Canadian dollar did not receive the domestic policy support that might have helped it counter the strength of the U.S. dollar or mitigate global risk aversion. This steady-but-above-target inflation, combined with flat job numbers, provided little impetus for the Bank of Canada to act, thereby leaving the loonie susceptible to the dominant external forces at play in the currency markets.
