Donald Trump has threatened new tariffs on Europe amid his plans, creating problems for leaders and businesses. The International Monetary Fund (IMF) says uncertainty from these tariffs hurts the economy. IMF Managing Director Kristalina Georgieva said in October, “uncertainty is the new normal” during Trump’s era. Businesses delay investments when policies are unclear, just like during Britain’s long Brexit talks. Trump’s plan could set 10% tariffs in February, rising to 25% in June. This risks slowing economic growth in Europe, especially in France, Germany, and the UK. UK Chancellor Rachel Reeves faces tough timing for recovery. The US also faces risks from higher prices. Tariffs over the last year are the highest since World War II, touching food imports like coffee and avocados. Trump even reduced tariffs on some food in November. But prices might still rise as stocks run out and companies face higher costs. This inflation could stop the US Federal Reserve from cutting interest rates, a key goal for Trump. Markets reacted strongly last year to Trump’s tariff threats but then seemed calmer, with investors betting on continued stock growth. Still, experts warn that using tariffs as a weapon might trigger market shocks and higher interest rates. As Kristalina Georgieva says, “buckle up” for rough times ahead.
