History

Historical Context

In 1980, Fed Chair Paul Volcker lifted the federal funds rate from 11.5% to 17.6% by April, confronting inflation that peaked at 13.5% and triggering a recession that began in January. The oil-price shock that prompted OPEC’s output cuts reappeared in 2023-24, sending Brent above $109 and the 10-year Treasury yield past 4.5%, reviving Volcker-era market concerns.
