Which of the following problems played the most important role in the creation of a boom and bust economy in the 1970s and the collapse of Penn Square Bank in 1982?

Changing oil prices drove the boom-and-bust cycle. When oil prices rose, energy businesses expanded and banks such as Penn Square made many loans tied to oil and gas; when prices fell, borrowers struggled to repay those loans, contributing to the bank’s collapse in 1982. The best answer is “changing oil prices.”
