Not shown because the BLS began these indexes after 1955: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), recreation (1993–), education & communication (1993–).
1981 was the year the inflation fever finally broke, at an extraordinary price.
Consumer prices rose 10.3%, the second year of back-to-back double-digit
inflation and the last time the U.S. would see one. To end it, Paul Volcker’s
Federal Reserve drove its policy rate above 19% and let borrowing costs go
where they may: a 30-year mortgage cost more than 18% by autumn, car loans and
business credit froze, and homebuilders mailed the Fed two-by-fours in protest.
The squeeze tipped the economy into recession in July, the deep 1981–82
downturn that would push unemployment past 10%. But it worked. Inflation fell
by nearly half within a year and to under 4% by 1983, the disinflation that
defined the following two decades. Even the price of mailing a letter told the
year’s story: postage went up twice in eight months.
