What is a sign that makes it clear thta a country's economy is in difficult?

When interest rates are lowered.

Banks do not want low interest rates because their profits will be lower as the interest paid by citizens to borrow money or open a mortgage will be lower.

Obviously there are many other indicators and data to consider, but interest rates are a tool that is used to try not to collapse the economy.

What did the FED do?

They cut the interest rates... of 50bps...
