The “Greenspan Put” is a term used to describe the monetary policies enacted by former Federal Reserve Chairman Alan Greenspan, aimed at preventing significant declines in the stock market. These policies typically involved lowering interest rates or implementing measures that provided financial markets with liquidity during economic downturns.
Historical Context of the Greenspan Put
Origin and Development
The moniker “Greenspan Put” emerged during the late 1990s when markets observed Greenspan’s interventions during financial crises. It is a metaphorical reference, comparing Greenspan’s policy actions to a “put option” in financial markets, which offers investors the right to sell assets at a predetermined price, thus limiting downside risk.
Major Interventions
The 1987 Stock Market Crash
One of the first significant applications of this strategy was in response to the 1987 stock market crash, where Greenspan’s Federal Reserve swiftly increased liquidity to stabilize markets.
The Dot-com Bubble
In the late 1990s, during the Dot-com bubble, Greenspan’s policies were perceived as supportive to the markets by lowering interest rates and fostering a conducive environment for economic expansion, despite overvaluations in tech stocks.
Mechanisms of the Greenspan Put
Interest Rate Adjustments
Lowering the Federal Funds rate was a primary tool used under Greenspan’s tenure to ensure economic stability and encourage investment and spending.
Where:
- \(i\) = nominal federal funds rate
- \(r\) = real federal funds rate
- \(\pi\) = inflation rate
- \(\pi^*\) = target inflation rate
- \(y\) = logarithm of real output
- \(y^*\) = logarithm of potential output
Liquidity Provisions
The Federal Reserve would also use various mechanisms to inject liquidity into the financial system, ensuring banks and financial institutions had enough reserves to meet demand.
Examples of the Greenspan Put in Action
1998 Long-Term Capital Management Crisis

Comparison with the Fed Put
Similarities

While the specific tools and circumstances might vary, the underlying principle of market intervention for stability remains consistent.
