Gold as an Inflation Hedge: What the Past 50 Years Teaches Us
And what the future of gold looks like.
And what the future of gold looks like.
On a Sunday evening 50 years ago—on Aug. 15, 1971, to be exact—then-President Nixon interrupted “Bonanza,” one of the most popular TV shows of that era, to announce that he was ending the convertibility of the U.S. dollar into gold. Many consider it to be one of the most consequential decisions he made.
Up until this “closing of the gold window,” foreign central banks had been able to convert U.S. dollars into gold bullion at the fixed price of $35 an ounce. In theory, this had imposed a strict monetary discipline on the Federal Reserve, since inflating the money supply could have caused a run on Fort Knox, where the U.S. stored its supply of gold. And inflation did indeed jump in the years following Nixon’s decision to remove that restraint. So did the price of gold, which today is 50 times as high as it was that day.
This apparent correlation between gold and inflation has led many to believe that gold is a good inflation hedge. This belief isn’t supported by the data, however. If gold were a good and consistent hedge, the ratio of its price to the consumer-price index would have been relatively steady over the years. But that hasn’t been the case, as you can see from the accompanying chart: Over the past 50 years, the ratio has fluctuated from a low of 1.0 to a high of 8.4.
Gold is only a good inflation hedge over time frames far longer than any of our investment horizons, according to research conducted by Duke University professor Campbell Harvey and Claude Erb, a former commodities portfolio manager at TCW Group. They found that it’s only when measured over very long periods—a century or more—that gold has done a relatively good job maintaining its purchasing power. Over shorter periods its real, or inflation-adjusted, price fluctuates no less than that of any other asset.
Gold’s weakness as an inflation hedge may be even more pronounced today, Prof. Harvey says, because “gold is currently very expensive compared to its history.” The current gold-to-CPI ratio stands at 6.7, for example, nearly double its 50-year average of 3.6.
Even though the price of gold is 50 times as high as in 1971, stocks have performed even better. The S&P 500 has produced an annualized return of 11.2% since August 1971, assuming dividends were reinvested along the way. That compares with 8.2% annualized for gold.
Furthermore, the only reason gold came even this close to matching stocks over the past 50 years was its huge return during the first decade following Nixon’s announcement. Take away that decade, and gold has lagged behind even intermediate-term Treasury notes. Over the past 40 years, gold has risen at a 3.6% annualized rate, compared with 12.2% for the S&P 500 and 8.2% for the Treasurys.
This doesn’t mean gold has no role to play in a diversified portfolio, however, even assuming the future will be like the past. Because the correlation of its returns with those of either equities or bonds has often been low or even negative, its presence in a portfolio can reduce volatility. Over the past 50 years, a stock-and-bond portfolio could have improved its risk-adjusted performance by adding a small allocation to gold—around 5% or so.
Still, even gold’s volatility-reducing potential isn’t guaranteed, since gold’s correlation with stocks has varied widely over the years. In fact, there have been occasions in which gold’s correlation to the stock market has been positive, which is just the opposite of what it should be to reduce a portfolio’s risk. One such recent occasion came during the stock market’s waterfall decline in February and March last year: Stocks of gold-mining shares dropped 39%, as measured by VanEck Vectors Gold Miners ETF (GDX)—even more than the 34% drop in the S&P 500. “What kind of safe haven is that?” Prof. Harvey asks.
Gold’s inconsistent correlation with both stocks and inflation makes it difficult to project how it will perform over the next 50 years. An additional wild card, according to Prof. Harvey, is that gold now faces “competition it’s never had before” because of the advent of cryptocurrencies.
It is always possible that gold will be a more consistent inflation hedge in coming years. It’s just that you will have to look elsewhere than history to find support for such a possibility. Mr. Erb is cynical whether this will pose much of an obstacle to gold’s true believers, however: “The past can always be brushed aside when dreaming about how gold and inflation might move in tandem in the future.”

Amazon, Google, Microsoft and Meta pour billions into artificial intelligence, undeterred by DeepSeek’s rise
Tech giants projected tens of billions of dollars in increased investment this year and sent a stark message about their plans for AI: We’re just getting started.
The four biggest spenders on the data centers that power artificial-intelligence systems all said in recent days that they would jack up investments further in 2025 after record outlays last year. Microsoft , Google and Meta Platforms have projected combined capital expenditures of at least $215 billion for their current fiscal years, an annual increase of more than 45%.
Amazon.com didn’t provide a full-year estimate but indicated on Thursday that total capex across its businesses is on course to grow to more than $100 billion, and said most of the increase will be for AI.
Their comments in recent quarterly earnings reports showed the AI arms race is still gaining momentum despite investor anxiety over the impact of China’s DeepSeek and whether these big U.S. companies will sufficiently profit from their unprecedented spending spree.
Investors have been especially shaken that DeepSeek replicated much of the capability of leading American AI systems despite spending less money and using fewer and less-powerful chips, according to its Chinese developer. Leaders of the U.S. companies were unbowed , touting advances in their own technology and arguing that lower costs will make AI more affordable and grow the demand for their cloud computing services, which AI needs to operate.
“We think virtually every application that we know of today is going to be reinvented with AI inside of it,” Amazon Chief Executive Andy Jassy said on Thursday’s earnings call.
Here is a breakdown of each company’s plans:
Amazon said a measure of its capex that includes leased equipment rose to a record of about $26 billion in the final quarter of 2024 , driven by spending in its cloud-computing division on equipment for data centers that host AI applications. Executives projected it would maintain the fourth-quarter spending volume in 2025, meaning an annual total of more than $100 billion by that measure.
The company—which gets most of its revenue from e-commerce and most of its profit from cloud computing—also projected overall sales for the current quarter that missed analysts’ expectations. Its shares slid about 4% in after-hours trading Thursday. The stock rose more than 40% in 2024 and was up nearly 9% this year before its earnings report.
Jassy said AI has the potential to propel historic change and that Amazon wants to be a leader of that progress.
“AI represents for sure the biggest opportunity since cloud and probably the biggest technology shift and opportunity in business since the internet,” Jassy said.
Google shares are down about 7% since its earnings report Tuesday, which showed disappointing growth in its cloud-computing business. Still, parent-company Alphabet said it is accelerating investments in AI data centers as part of a surge in capital expenditures this year to about $75 billion, from $52.5 billion in 2024. The spending will go to infrastructure both for Google’s own use and for cloud-computing clients.
“I think part of the reason we are so excited about the AI opportunity is we know we can drive extraordinary use cases because the cost of actually using it is going to keep coming down,” said CEO Sundar Pichai .
AI is “as big as it comes, and that’s why you’re seeing us invest to meet that moment,” he said.
Microsoft has said it plans to spend $80 billion on AI data centers in the fiscal year ending in June, and that spending would grow further next year , albeit at a slower pace.
Chief Executive Satya Nadella said AI will become much more extensively used , which he said is good news. “As AI becomes more efficient and accessible, we will see exponentially more demand,” Nadella said.
Growth for Microsoft’s cloud-computing business in the latest quarter also disappointed investors, leaving its stock down about 6% since its earnings report last week.
Meta, too, outlined a sizable increase in its investments driven by AI, including $60 billion to $65 billion in planned capital expenditures this year, roughly 70% higher than analysts had projected. Shares in Meta are up about 5% since its earnings report last week.
CEO Mark Zuckerberg said investing vast sums will enable it to adjust the technology as AI advances.
“That’s generally an advantage that we’re now going to be able to provide a higher quality of service than others who don’t necessarily have the business model to support it on a sustainable basis,” he said.
