Answer:
OPEC was protesting US support of the Israeli military during the Yom Kippur War when it imposed its embargo.
Step-by-step explanation:
In response to US aid to Israel, OPEC raised its oil price from 70% on October 16, 1973 to $ 5.11 a barrel. Saudi Arabia and the other Arab oil-producing states joined the embargo on October 20, 1973.
Price increases were also imposed. As short-term demand for oil is inelastic, immediate demand falls little as the price rises. As a result, market prices rose from $ 3 a barrel to $ 12 a barrel to adjust demand to lower new supply. The world financial system, which was already under pressure from the Breton Woods collapse, was set on a recessionary path and inflation, which persisted until the early 1980s, with oil prices remaining high until 1986.
