Beyond the duration of the shock, we also need to monitor the impact on central banks and on the macroeconomy. Societe Generale’s Manish Kabra lays out the criteria as follows: An exogenous shock lasts beyond a week, but oil spikes usually peak in three months.

Large and sustained oil price spike: An oil price spike of at least +50-100% that is sustained over several months. 2. Hawkish policy response: The shock forces a sharp, hawkish pivot from central banks to fight the resulting inflation (e.g. 1979, 2022). 3. Broader macro damage: The shock is big enough to tip an already-slowing economy into recession. Iran Oil Panic: Enough Cool Heads Are Pulling Back From the Brink - Bloomberg
