If Trump is elected again and continues to pursue this protectionist policy, there will be increased pressure on the supply chain, further pushing up prices. In the future, this could cause inflation to rise again, forcing the Fed to take drastic interest rate hikes. Looking back in history, the Federal Reserve raised interest rates to 20 percent in the 1980s to counter inflationary pressures at the time. If the economic situation worsens, the market may again experience a sharp change in interest rates, which will have a profound impact on investors and the economy as a whole.
