Exogenous shocks usually lead to economic slowdowns, as in the case of an oil shock leading to higher prices, inflation, reduced consumer spending, increased unemployment, and a slowing economy.

This would reduce the price of oil and boost the economy, potentially overheating it in which causes high inflation and increased interest rates that ultimately slow the economy down. In a financial crisis the result is usually characterized by banks becoming vulnerable and requiring action by the central bank to stabilize the banking system and economy by increasing liquidity and lowering interest rates.
