Volcker vs. Greenspan: Two Very Different Fed Chairs
The Problems They Inherited
Paul Volcker took office in August 1979 with consumer price inflation in double digits, a currency under pressure, and a public that had stopped believing the Fed would ever bring prices under control. His task was to destroy an entrenched expectation. Alan Greenspan took office in August 1987 with inflation already broken and expectations re-anchored — Volcker's bequest — and with an immediate crisis of a different kind two months later, when the stock market fell more than twenty percent in a single October day. Greenspan's task for the next eighteen years was not to re-establish credibility but to spend it wisely: keeping an expansion going without letting inflation return.
Method: Shock Treatment vs. Fine-Tuning
Volcker's signature move was procedural. In October 1979 the FOMC shifted from steering the federal funds rate directly to targeting the quantity of bank reserves, which let short-term rates go wherever the market took them — at times above nineteen percent — and gave the committee political cover for outcomes no one would have voted for as a headline number. Greenspan worked in the opposite register: small, incremental, well-telegraphed changes, usually a quarter point at a time, guided by close reading of incoming data and by his own judgment about productivity trends. Volcker changed the regime; Greenspan optimized within one. Both approaches assumed something the other did not — Volcker that credibility had to be bought, Greenspan that it could be spent.
Communication and Transparency
Volcker's Fed operated in an era when the committee did not announce its decisions at all; markets inferred policy from the New York desk's open market operations. Greenspan presided over the first real steps toward openness, including the decision in February 1994 to announce policy changes on the day they were made — a genuine break with a century of deliberate opacity. Even so, Greenspan cultivated a famously indirect style, once remarking that if he seemed unusually clear his listeners must have misunderstood him. The full move to plain-language transparency, with an explicit inflation target, published projections, and regular press conferences, came only under his successors.
Records and Legacies
Volcker's record is stark and largely settled: inflation fell from roughly fourteen percent in early 1980 to about four percent by 1983, at the cost of two recessions and unemployment above ten percent. Economists across the spectrum credit that episode with re-anchoring expectations for a generation. Greenspan's record is more contested. His supporters point to the length and stability of the 1990s expansion and to the swift responses to the 1987 crash and the 1998 market turmoil. His critics argue that policy was left too accommodative in the early 2000s and that his confidence in market self-regulation contributed to the conditions behind the 2008 crisis — a criticism he partly acknowledged in congressional testimony in 2008.
What Students Should Take From the Contrast
The pair illustrates the central trade-off in monetary policy: rules and credibility versus discretion and flexibility. Volcker demonstrated that a central bank can defeat inflation if it is willing to accept the real output cost and if the public comes to believe it will not back down. Greenspan demonstrated how much easier policy becomes once that belief exists — and, in the eyes of critics, how quietly the resulting freedom can be over-used. Modern central banking tries to keep both lessons: an explicit numerical target and transparent communication to protect credibility, plus enough operational flexibility to respond to shocks that no rule anticipated.
