The US dollar weakened against its Canadian counterpart on Thursday, touching its lowest level in four weeks, as a pullback in Treasury yields and a surge in oil prices combined to weigh on the greenback.
The 10-year Treasury yield fell to 4.965%, slipping back below the psychologically important 5% threshold. That move took some shine off the dollar's yield advantage, which had been a key support for the currency in recent months. The dollar was last trading near CA$1.4006, its weakest since September 21.
At the same time, oil prices jumped on rising Middle East tensions. US benchmark West Texas Intermediate (WTI) crude climbed to about $99.49 a barrel, while Brent crude rose to roughly $112.60. Because Canada is a major oil exporter, higher crude prices tend to boost the Canadian dollar, as they improve the country's terms of trade and bring more revenue into its energy sector.
Why yields matter for the dollar
Currencies often track where investors think interest rates are headed. When US yields rise relative to those in other countries, the dollar tends to attract more capital, as investors seek higher returns. Conversely, when yields fall, that advantage narrows, and the dollar can lose some of its appeal.
Thursday's move in the 10-year Treasury yield was notable because it came after a period of rising yields that had pushed the benchmark above 5% earlier in the week. The dip below that level signaled that some investors were stepping back from their bets on higher US rates, perhaps due to concerns about economic growth or a shift in risk sentiment.
This dynamic is not unique to the dollar. As AI stock jitters drive investors into Treasuries, yields can fall, and that can ripple through currency markets. In this case, the softer yield helped the Canadian dollar gain ground.
Oil's role in the loonie's strength
Canada is one of the world's largest oil producers, and its currency, often called the loonie, is closely tied to crude prices. When oil prices rise, the Canadian dollar typically strengthens because higher energy prices mean more demand for Canadian exports and a more favorable balance of trade.
The jump in oil prices on Thursday was driven by escalating tensions in the Middle East, a region that accounts for a significant share of global oil supply. Any threat to that supply can push prices higher, and markets were reacting to the latest headlines.
For investors, the combination of lower Treasury yields and higher oil prices created a one-two punch for the dollar. The greenback lost ground not just against the Canadian dollar but also showed weakness in other currency pairs, as the dollar split against major currencies ahead of a busy day of US economic data.
What it means for investors
For everyday investors, the dollar's decline against the loonie is more than just a currency market curiosity. It can affect the value of international investments, the cost of imported goods, and the returns on foreign assets.
If you hold US dollar-denominated assets, a weaker dollar means those investments are worth less when converted into Canadian dollars. Conversely, if you have exposure to Canadian stocks or bonds, a stronger loonie can boost your returns when you bring the money back into US dollars.
The drop in Treasury yields also has implications for bond investors. When yields fall, bond prices rise, which can be good news for those holding fixed-income securities. However, the move below 5% may also signal that investors are becoming more cautious about the economic outlook, which could weigh on stocks.
As high Treasury yields cool the IPO market, the broader impact of yield movements is being felt across asset classes. For now, the key question is whether the dip below 5% is a temporary blip or the start of a sustained decline.
What to watch next
Investors will be keeping an eye on several factors in the coming days. First, any further escalation in Middle East tensions could push oil prices even higher, which would likely strengthen the Canadian dollar further and put more pressure on the US dollar.
Second, the path of Treasury yields will be crucial. If yields continue to fall, the dollar could weaken further against other currencies as well. On the other hand, if yields rebound above 5%, the dollar may regain some of its lost ground.
Finally, upcoming US economic data, including inflation and jobs reports, could influence the Federal Reserve's policy outlook. As traders await Fed, ECB, and BOJ rate calls, any surprises in the data could shift expectations and move both yields and currencies.
For now, the dollar's slide against the loonie is a reminder that currency markets are driven by a complex mix of interest rates, commodity prices, and geopolitical risk. For investors, staying informed about these drivers can help you understand the forces shaping your portfolio.
