Explanation:

A crisis in the national bank led the country to a very strong economic imbalance, generating an economic crisis and a low circulation of money, leaving the country "in the red". This affected industrial and agricultural production, which had to increase product prices more and more rapidly, as the crisis extended, causing the purchasing power of citizens to decrease dramatically. This occurs when inflation is very high within the country.

Accordingly, we can say that a long-term effect of the National Bank crisis was that the economy was weakened by high inflation.
