Jim Grant on AI, Deflation, and the Risks of Financial Leverage

The veteran publisher of Grant's Interest Rate Observer draws historical parallels between today's AI excitement and past manias while highlighting the dangers of excessive debt and the misunderstood nature of falling prices.

In a wide-ranging conversation on the Meb Faber Show, legendary financial historian and publisher of Grant’s Interest Rate Observer, Jim Grant, offered a characteristically clear-eyed and contrarian view of today’s markets. His comments on artificial intelligence, the nature of deflation, Federal Reserve policy, and excessive financial leverage carry important implications for investors in gold, silver, and mining stocks.

AI: The Biggest Bubble of Our Time?

Grant sees the current excitement around artificial intelligence as one of the largest speculative episodes in modern history — potentially exceeding even the late-1990s internet bubble. He draws a direct parallel to the railroad boom of the 19th century, noting that both periods featured massive capital misallocation, overbuilding, and double-ordering of capacity. Just as the railroads led to a long period of falling prices (deflation) through productivity gains and creative destruction, Grant suggests AI could produce similar effects — though the scale of capital being deployed today is far larger.

“I think that today is one of the greatest bubbles of all time.”

He is particularly skeptical that better technology will prevent the classic mistakes of previous manias. Human nature, he argues, remains prone to over-optimism when large sums of money are involved.

Deflation Is Not Always a Disaster

One of Grant’s most important points is his reframing of deflation. While central bankers and many economists treat falling prices as inherently dangerous, Grant argues that what the Fed often labels “deflation” is frequently just progress. Technological advances — whether railroads, steam power, the telegraph, or air conditioning — have historically driven down the cost of goods and services while raising real wages. The long deflationary period after 1873 in the United States, for example, coincided with significant improvements in living standards. Grant criticizes former Fed Chair Ben Bernanke for overemphasizing the risks of 1930s-style deflation during the 2008–2012 period. He believes this mindset contributed to excessively loose monetary policy that helped inflate today’s high levels of debt and asset prices.

The Fed’s Constraints: Too Much Leverage

Grant is highly critical of the current level of financial leverage in the system — particularly in private equity, private credit, and among lower-rated corporate borrowers. He notes that much of this debt was taken on when interest rates were near zero. This creates a major constraint for the Federal Reserve. Even if inflation remains above target, the Fed may be reluctant to raise rates aggressively because doing so could trigger widespread distress among over-leveraged borrowers.

“There’s a real issue for lower-rated corporate borrowers of rolling over their debt incurred at very low rates of interest at today’s rates.”

He also highlights problems in the life insurance industry, where a significant portion of assets has moved into private credit — a sector he views as somewhat opaque and potentially vulnerable.

On Gold and Monetary Disorder

Grant has been a long-term holder of gold, viewing it primarily as a hedge against currency debasement rather than a short-term trading vehicle. He notes that gold can underperform for extended periods (as it did after its 1980 peak), but he sees its long-term role as a store of value in an era of persistent monetary expansion. He points out that gold has lost none of its monetary characteristics, even as paper currencies have continued their long-term decline in purchasing power.

Implications for Canadian Mining Investors

Grant’s worldview has several direct takeaways for investors in the Canadian resource sector:

• Gold and silver remain relevant: In an environment of high debt, monetary uncertainty, and potential financial instability, precious metals and the companies that produce them retain strategic importance.

• Beware of leverage-driven volatility: Mining stocks are inherently cyclical and sensitive to interest rates and economic conditions. High levels of systemic leverage increase the risk of sharp moves in either direction.

• Productivity and deflation can be positive: Not all price declines are bad. Technological progress that lowers input costs (energy, materials, equipment) can ultimately benefit well-run mining operations.

• AI-related capital spending is a double-edged sword: While AI-driven demand could support certain metals (particularly copper and uranium), the current level of enthusiasm and capital deployment carries classic bubble characteristics. Overbuilding in data centers and related infrastructure could eventually lead to a correction.

• Focus on quality and balance sheets: In a higher-for-longer or more volatile interest rate environment, companies with strong balance sheets, low costs, and credible paths to production are likely to outperform.

Final Thoughts

Jim Grant’s perspective is grounded in history but applied rigorously to the present. He does not dismiss technological progress — he simply refuses to believe that human behavior has fundamentally changed. Bubbles still form. Leverage still creates fragility. And monetary systems still tend toward gradual (or sometimes rapid) debasement. For Canadian mining investors, his message is clear: remain disciplined, respect valuation and leverage risks, and recognize that gold and silver continue to serve as important portfolio anchors in an uncertain monetary environment. The current period may feel unique, but as Grant reminds us, markets have a way of repeating familiar patterns — often when people least expect it.
