Players in the Challenger tier are considered to be among the best in the world, while those in the Master tier are still highly skilled but have not yet reached the top 200.

The ECB can contain inflation through a restrictive monetary policy by increasing interest rates. Higher interest rates make borrowing more expensive, which can reduce consumer spending and investment, ultimately slowing down economic growth and inflation.

By implementing these measures, the ECB can effectively control inflation and maintain price stability in the economy. **
