Donald Trump's victory in the 2024 U.S. presidential election has led to a surge in stock markets and cryptocurrencies, driven by investor optimism about potential economic growth and market-friendly policies. The win has prompted expectations of significant economic shifts, including protectionist trade policies such as high tariffs on Chinese and global imports, which could impact global trade and economic growth. While Trump's 'America First' agenda continues, the Republican control of the Senate could facilitate the implementation of his policies. However, potential economic consequences include increased inflation and interest rates in the U.S. and abroad, notably affecting the UK economy. Trump's return also impacts his legal battles, potentially stalling prosecutions and civil cases due to presidential immunity. The market's response reflects both the anticipation of Trump's policies and the broader implications for global economic stability.
