What are Shadow Interest Rates and Why Should You Care?

In a nutshell, shadow interest rates are theoretical rates that exist below zero. Traditional interest rates can't go below zero because people would simply hold cash instead of lending it out at a loss. However, economic models suggest that the impact of monetary policy can sometimes be equivalent to having rates far below zero. These are the shadow rates.
- More Accurate Assessment: They provide a more realistic view of monetary policy's effectiveness, particularly when standard rates are near zero.
