(Please don't put the same answer of someone else unless you actually know its that answer).

C. Changes oil prices

Explanation:

The failure, which harmed the entire banking sector of the United States, occurred in 1982. Penn Square Bank has financed major oil exploration projects for potential oil fields and financed the extraction of that derivative from existing wells. The bank achieved success by lending and eventually selling its stake to other banks. The fall in the price of oil in 1981 was catastrophic for the bank's operations. The savers withdrew over $ 50 million in the spring of 1982, and the bank did not survive the summer of the same year.
