How do rising oil prices affect the inflation rate?
Rising oil prices tend to affect the overall consumer price index (CPI) directly by raising its energy cost component, which includes the prices of energy-related items, such as household fuels, motor fuels, gas, and electricity. Among these, gasoline and fuel oil are directly derived from crude oil, so their prices follow oil prices very closely. An increase in the price of oil may also affect energy costs through the prices of other items that are close substitutes; for example, households and businesses may switch from oil-related energy items to natural gas, thus leading to an increase in its price. The extent to which rising oil prices translate into higher overall inflation through higher energy costs depends on their persistence. If they continue to rise, they may lead to sustained increases in the overall price level, that is, to an increase in the overall inflation rate.
