Financial markets worldwide are experiencing volatility as trade tensions between the United States and Canada escalate. The recent imposition of tariffs by both nations has led to concerns over a potential trade war, impacting investor sentiment and causing fluctuations in currency and commodity markets. 

Global automakers are anticipating significant disruptions due to the U.S. administration's 25% tariff on imported cars and auto parts. This policy aims to boost domestic jobs and tax revenues but is expected to raise vehicle prices and potentially harm U.S. consumers. Key trading partners are considering retaliatory measures, heightening fears of a trade war.
