Which factor contributed most inflation in the us during the 1970s?

The primary factor contributing to inflation in the U.S. during the 1970s was the combination of oil price shocks and supply chain disruptions. The 1973 oil embargo, imposed by OPEC, led to skyrocketing fuel prices, which in turn increased transportation costs and affected the prices of goods across the economy. Additionally, accommodating monetary policies and wage-price controls further exacerbated inflationary pressures, resulting in stagflation—characterized by stagnant economic growth and high inflation.
