Randy Kroszner argues that Alan Greenspan was both highly consequential and deeply mixed as a Fed chair: he helped support a long expansion and recognized the productivity boom, but also helped foster excess risk-taking and leverage that later fed the housing and global financial crises. The conversation centers on Greenspan’s legacy, Fed communication, and what lessons today’s Fed should take from his preference for big-picture judgment over reacting to every data print.

This is a short Bloomberg interview in which Randy Kroszner reflects on Alan Greenspan’s legacy and what it means for the modern Fed. Kroszner’s core view is balanced rather than celebratory or condemnatory: Greenspan “contributed enormously to economic growth in The US,” got “many calls right,” and helped support the late-1990s expansion, but he also bears some responsibility for the risk-taking and leverage that contributed to the housing bubble and global financial crisis. Kroszner highlights Greenspan’s decision not to hike aggressively during the productivity boom as a key positive. In his telling, Greenspan recognized that the late-1990s productivity surge justified allowing the economy to run hotter, which helped employment grow more than it otherwise would have. …
Tactically, the only actionable message is to expect Fed commentary to matter less as a string of reactions to each release and more as a signal of communication style. Near-term risk is over-interpreting every data print through a Greenspan-style lens.
Over the next few weeks/months, the Fed may move toward cleaner, less cluttered messaging that emphasizes broader trends rather than noisy datapoints. That would validate the speaker’s view; a more guidance-heavy Fed would push against it.
The structural takeaway is that central banks face an enduring tradeoff between supporting growth and containing excess. Greenspan’s legacy, in Kroszner’s framing, is that policy regimes can prolong expansions while also sowing fragility.
Greenspan's belief that the Fed could easily clean up after a crisis led him to accept excess risk-taking, which contributed to the global financial crisis.
The speaker explains Greenspan's trade-off: prioritize long growth and accept downside risk because he thought the Fed could easily clean up later, which proved costly.
Alan Greenspan contributed enormously to US economic growth.
The speaker opens with this as a positive assessment of Greenspan's legacy.
Greenspan's view that people with their own money at stake would always do full due diligence turned out to be wrong, contributing to bubbles and the financial crisis.
The speaker recounts Greenspan's post-crisis admission that his assumption about market participants' due diligence was flawed, allowing bubbles to form.
How should we view Alan Greenspan's legacy?
Greenspan contributed enormously to US economic growth, making many right calls like seeing the productivity boom in the late 1990s and holding back on raising rates, which helped employment grow. However, he also contributed to risk-taking that led to the global financial crisis, particularly by helping build leverage in the housing system.
Is it a fair characterization that Greenspan helped build leverage that ended up in the great financial crisis?
Randy explains Greenspan's view was that the Fed could clean up after a crisis fairly easily, and if the Fed tightened too much early on it would strangle growth and innovation. Greenspan made a trade-off to have many years of growth at the risk of some downside, believing the Fed could clean it up. When Randy was at the Fed they tried to clean it up, but it probably had a bigger cost than Greenspan anticipated.
How much has Fed communication evolved and how much do you expect it to evolve going forward under Walsh?
It was amazing that the Fed didn't talk before — you knew nothing about what they were doing. Greenspan introduced the first statements. Kevin Morris, who served on the Fed with Randy, wants to move back to simpler communication with less forward guidance, something more plain vanilla, to help the Fed think in big picture terms rather than responding to every data point — focusing on what AI means, what supply shocks mean, and conveying that big picture to the market.
