The Federal Reserve (the central bank in the US) cut interest rates by 25 basis points overnight. That might sound like good news for people in the United States, but it actually highlights a worrying problem.
The US economy is facing rising inflation and unemployment. Inflation has increased from 2.3% in April to 2.9% in August. At the same time unemployment has hit a 4 year high of 4.3%, with the growth in new jobs slowing substantially in the last 4 months.
Increasing inflation and unemployment is called stagflation, and it is a central banks worst nightmare. Why? Because usually when inflation is high unemployment is low and when unemployment is high inflation is low.
This means that the Federal Reserve usually fights either inflation or unemployment, not both at the same time.
To combat high inflation the central bank increases interest rates. This slows price increases (inflation) by slowing the economy and increasing unemployment. Usually unemployment is already low, so this is not a problem.
When unemployment is high, the central bank does the opposite, it decreases interest rates to increase economic growth. This stimulates more employment, bringing unemployment down, but a faster growing economy can also increase prices. But again, this is not a problem because inflation is usually low.
If both unemployment and inflation are high, what should a central bank do? Increasing interest rates might make unemployment worse. Decreasing them might make inflation worse.
By cutting interest rates, the Federal Reserve has decided the threat of high unemployment is a bigger problem than the threat of inflation.
