Greenspan Put was the term coined to describe the strategies initiated by Alan Greenspan during his period as Federal Reserve (Fed) Chair. Serving from 1987 to 2006, Greenspan’s Fed was notably proactive in counteracting significant stock market declines, thereby providing a safety net against losses akin to a standard put option.

The Concept Behind Greenspan Put
As Federal Reserve Chair, Alan Greenspan used various policy tools, including adjustments to the federal funds rate, to uphold the U.S. economy. The ‘Greenspan Put’ essentially translates to an implicit assurance that the Fed would step in to prevent drastic market falls, particularly around the 20% mark signaling a bear market. This indirect insurance kept investor fears at bay, limiting concerns over prolonged, costly downdraws.
Greenspan’s interventionist approach spurred investors toward riskier stock ventures, fostering market bubbles and volatilities. Conversely, seasoned investors resorted to buying put options as hedges to protect portfolios against precipitous drops triggered by bubble bursts.
Put Protection Strategies
Puts are crucial for hedging against price risks, giving traders a way to offset unfavorable market movements. During downturns, such as the internet stock crash from 2000 to 2002, effective use of put options helped many mitigate losses. For instance, had an investor bought an internet stock rising dramatically, purchasing a put option for protection as prices slowed could preserve gains against subsequent declines.
The Greenspan Put differs from structured put strategies; it’s a broader assertion rather than a specific trading methodology. It embodies the ideology that Greenspan’s Fed wouldn’t let market collapses persist unchecked, often boosting the profitability of put options around crises.

Historical data from 1997 onwards highlight sustained higher implied volatility, affirming why investors placed continual faith in the potential for intervention following major market swings, thereby perpetuating the use of the Greenspan Put.
Greenspan’s Policies and the Fed’s Role
One notable act of Greenspan post his appointment was the response to the 1987 stock market crash. Lowering rates swiftly, he set a standard for tactical intervention during economic turmoil. His strategy for managing rates cultivated a perceived backing that implicitly encouraged stock market risk by offering rescue assurances, especially during pronounced peaks and troughs.
Unadjusted valuations and resultant rampant stock price fluctuations during the 1990s pressed even veteran investors to adopt put options as a hedge. The frequent rate cuts of the period further spurred this approach, embedding an era of risk-taking buoyed by perceived Fed support.
The sequence of Fed interventions during significant events, from crises like Long-Term Capital Management to the dotcom bust, underpins the ongoing correlation.

The incumbency of subsequent Fed Chairs like Ben Bernanke mirrored this phenomenon during the 2007-2008 period, interweaving rate cuts and similar props that some argue paved pathways to the 2008 financial turbulence. Notably, post-2008, similar Fed policies under Bernanke, Janet Yellen, and Jerome Powell have demonstrated varied outcomes on market risk dynamics, with generally lower post-crisis volatility.
