Canada's currency came under renewed pressure Monday as investors weighed U.S. tariff threats, falling oil prices and the global interest-rate outlook.

The Canadian dollar was trading about 0.1% lower at C$1.4095 per U.S. dollar, or roughly 70.95 U.S. cents, after reaching its weakest intraday level since July 14. The loonie also recorded a weekly decline of about 0.5%.

The latest movement comes as Canadian businesses continue to navigate uncertainty surrounding U.S. trade policy. Washington has threatened tariffs of up to 50% on a broad range of Canadian goods, creating additional risks for exporters, manufacturers and companies operating across North American supply chains.

Oil prices are another important factor for Canada's economy and currency. Crude prices recently pulled back after a sharp rise, while investors continued to monitor disruptions to global energy supplies and geopolitical developments. Because energy exports are a major part of Canada's economy, fluctuations in oil markets can have an important influence on the Canadian dollar.

The currency move also comes as investors prepare for important central-bank decisions and economic data. Markets are watching interest-rate expectations closely because changes in borrowing costs can affect consumer spending, business investment and the broader Canadian economy.

For Canadian companies, the weaker loonie creates both challenges and opportunities. Importers may face higher costs for goods priced in U.S. dollars, while exporters can benefit from more favourable currency conversion.

The latest market movement highlights how trade policy, energy prices and interest rates are increasingly interconnected with Canadian business conditions.
