Economic stability
Economic stability refers to an absence of excessive fluctuations in the macroeconomy. An economy with fairly constant output growth and low and stable inflation would be considered economically stable. An economy with frequent large recessions, a pronounced business cycle, very high or variable inflation, or frequent financial crises would be considered economically unstable.
Theoretical Definition
A financial system is stable when it dissipates financial imbalances that arise endogenously or as a result of significant adverse and unforeseeable events. When stable, the system absorbs shocks primarily via self-corrective mechanisms, preventing the adverse events from disrupting the real economy or spread over to other financial systems. Financial stability is paramount for economic growth, as most transactions in the real economy are made through the financial system.
Without financial stability, banks are more reluctant to finance profitable projects, asset prices may deviate significantly from their intrinsic values, and the payment settlement schedule diverges from the norm. Hence, financial stability is essential for maintaining confidence in the economy. Possible consequence of excessive instability includes: bank runs, hyperinflation, or stock market crashes.
