As investors pour into artificial intelligence and keep paying up for towering valuations, the late Alan Greenspan’s long-running case for gold as a hedge against inflation and monetary excess is being debated again—alongside reminders that his record on marke
When Alan Greenspan warned the U.S. about “irrational exuberance” in 1996, many investors shrugged. The stock market kept climbing for years, and the eventual bust reshaped how people viewed his influence.
Three decades later, Greenspan’s death at age 100 has put his ideas back in the spotlight—especially a question many now ask in real time as money flows toward artificial intelligence and trillion-dollar valuations become routine. Was he also right about gold?
Greenspan believed gold was more than a shiny asset. In a 1966 essay titled “Gold and Economic Freedom. ” first published in Ayn Rand’s financial newsletter. The Objectivist. he argued gold was a safeguard against excessive government spending. inflation. and “easy money.” He warned that abandoning a gold-backed monetary system would make it easier for governments and central banks to expand the money supply. steadily eroding the purchasing power of paper currencies.
For investors, those arguments have gained a sharper edge over the past several decades. Since the global financial crisis. central banks have relied on multiple rounds of quantitative easing. government debt has climbed to record levels. and inflation has surged well above the Federal Reserve’s long-term target. In that environment, many see the same ingredients Greenspan believed would strengthen gold’s appeal as a store of value.
“Greenspan’s philosophies around gold hold to be true to an extent in certain aspects. ” said Ryan Lee. Chief Analyst of universal exchange Bitget. “Gold may never be able to deliver the same growth profile as equities or emerging technologies in the short term. but it can act as insurance against currency debasement. inflation uncertainty. and policy volatility in the long run.”.
Greenspan’s thinking on gold didn’t begin with his time at the Federal Reserve. In the decades before he led the central bank, he laid out why gold, in his view, was uniquely suited to storing wealth: it is scarce, durable, homogeneous, and easy to split.
He also warned that alternatives to a gold standard could be dangerous. Without the ability to convert goods and services into gold, governments could print money, lend against non-tangible “assets” such as government bonds, and risk destabilizing the global economy.
Still, Greenspan’s career also exposed the limits of some convictions. Years later, he would publicly reconsider at least one of his core beliefs—an admission that complicates any attempt to read today’s gold debate as purely vindication.
In 1996, Greenspan delivered his most famous market warning when he cautioned the U.S. about “irrational exuberance” in publicly-traded company valuations. He argued it would lead to a bubble. and that the bursting of that bubble could bring an economic depression comparable to what Japan had faced in the preceding decade. The country ignored those warnings. and the recession that followed the dot-com bubble burst ended what was then the longest stretch of economic growth and expansion the United States had ever seen.
Now. almost 30 years after the phrase “irrational exuberance” entered the mainstream. investors are again channeling capital toward a transformative technology—artificial intelligence. The surge in valuations. the rise of trillion-dollar companies. and the optimism surrounding the AI boom have led some economists to draw echoes to the late 1990s dot-com period.
If Greenspan had been sitting in the chairperson seat of the Federal Reserve today, Lee said, he might have leaned toward letting markets correct themselves. He would likely have cautioned investors to keep gold in mind as a safe haven.
“He would’ve likely argued that gold still has a place as a stabilizing asset and would’ve embraced digital assets and other innovations,” Lee said.
Yet Greenspan’s legacy is not tidy. He acknowledged being wrong about a laissez-faire economy when that theory was tested and failed. And he also admitted flaws in how banks acted under conditions meant to allow self-correction.
In the aftermath of the bubble bursting, Greenspan maintained a hands-off approach and kept interest rates low, a stance critics link to the next major boom: the United States housing bubble.
Then, in a congressional hearing in 2008, he famously said he had found a flaw. He told lawmakers: “I have found a flaw. I don’t know how significant or permanent it is. But I have been very distressed by that fact…I have been going for 40 years or more with very considerable evidence that it was working exceptionally well.”.
That admission matters for the question at the center of the renewed debate. Greenspan maintained that gold’s scarcity and inherent value made it a strong investment in a chaotic market. In his framework, a free market stretched by excessive credit would eventually see rising interest rates. Those rates would steer investors toward safer long-term investments like gold—offering a tangible hedge against inflation.
Over the last 15 years, some investors have pointed to developments that, in their view, strengthen that argument. Since the global financial crisis, central banks have carried out multiple rounds of quantitative easing. Government debt has climbed sharply. Inflation surged to multi-decade highs following the COVID-19 pandemic. Over the same period, gold prices have risen substantially, helping preserve purchasing power during economic stress.
But not everyone sees gold as the inflation answer. Jeremy Siegel—Professor Emeritus of Finance at the Wharton School of the University of Pennsylvania—has voiced concerns about gold’s ability to buffer inflation. In his view. gold holds value reasonably well. but it barely appreciates in the long term compared with index funds or REITs. He has also pointed out that gold doesn’t provide ongoing income, unlike stocks.
Siegel has additionally warned against using fears of market excess to abandon equities altogether.
So what happened to investors who followed Greenspan’s advice?. The uncomfortable reality is that both sides can claim something. Gold did benefit from forces Greenspan warned about—rising government debt, aggressive monetary policy, and inflation. But stocks still outperformed over the long run, including even after the dot-com crash and the financial crisis.
Had an investor exited the stock market after Greenspan’s 1996 “irrational exuberance” warning. they would have missed several years of substantial gains before the dot-com bubble eventually burst. In hindsight, Greenspan may have been better at identifying economic risks than predicting what investors would actually do with them.
The debate over whether Greenspan’s case for gold is “still golden” comes down to which parts of his economic worldview investors think still apply. He spent decades arguing that gold served as a safeguard against inflation, government overspending, and excessive monetary intervention. With the U.S. facing persistent inflation. massive government debt. and years of quantitative easing. the case for gold arguably looks stronger today than it did when he first made it.
But critics can point to a simple counterweight: stocks still won.
Whether Greenspan’s thesis ultimately holds up remains contested. What is clear is why investors are returning to it now. The push and pull between monetary excess. market optimism. and the search for safety explains why Greenspan’s gold arguments have resurfaced as investors chase AI growth and grapple with valuations that feel hard to ignore.
