Trump's Solo Powers: Tariffs, Deregulation, and Market Moves Without Congress

President-elect Donald Trump will have significant authority to influence markets and policy without needing approval from a Democratic-led Congress. Key tools include executive orders, tariff adjustments, and deregulation, which can be enacted swiftly. For instance, Trump can impose tariffs on imports under existing trade laws, affecting industries like steel and autos, and can roll back environmental and financial regulations through agency directives. These actions could impact major companies such as Apple, General Motors, and banks, as well as sectors like energy and healthcare. The 'why it matters' is that investors and businesses must navigate a landscape where presidential action can rapidly alter market conditions, supply chains, and compliance costs. With Democrats controlling the House, legislative gridlock is likely, shifting the focus to executive power. Markets may see volatility as policies shift without congressional checks. The takeaway: Trump's pen and phone will be the primary drivers of economic change, for better or worse.
