From Bretton Woods to central bank vaults, gold has maintained a singular presence in global finance.

Gold has served as a store of value and medium of exchange across more than five thousand years of recorded history. Ancient monetary systems on nearly every continent were built around it. The Bretton Woods international monetary order, which shaped the post-World War II global economy, was explicitly tethered to it until 1971, when the United States suspended the dollar’s convertibility and ushered in the modern era of fiat currency.
Yet gold did not retreat from financial markets when the gold standard ended. If anything, its role as an investable asset deepened. The infrastructure supporting global gold trading has grown substantially in the decades since: from physical bullion markets in London and Zurich, to futures and options on the COMEX, to physically backed exchange-traded products that democratized access beginning in the early 2000s.
Today, gold’s average daily trading volume sits at approximately $424 billion, placing it among the most liquid assets globally, more liquid by some measures than most individual sovereign bond markets outside of US Treasuries and select European government bonds. This liquidity comes from a genuinely global, multi-institutional market: central banks and sovereign wealth funds, commercial banks, institutional asset managers, commodity trading houses, physically backed ETF trusts, jewelry manufacturers, and retail investors all participate.
Understanding gold’s role in a portfolio begins with understanding this breadth of demand, and the structural reasons that demand has proven persistent across widely varying economic environments.
Gold’s Modern Journey
| 2000 ~$270 Near 20-year secular low. Dot-com euphoria drowns out gold interest. Real yields positive. | 2003–04 ~$400 Dollar weakness, low rates. First major physically backed ETF (GLD) launches in 2004. | 2008 ~$750 GFC: brief selloff during liquidity crisis, then strong recovery as real rates collapse. | 2011 ~$1,900 Peak. QE, eurozone debt crisis, inflation fears. Gold reaches nominal all-time high. |
| 2015 ~$1,050 Multi-year correction. Fed taper tantrum. Dollar strengthens. Real rates rise. | 2020 $2,000+ Pandemic: brief selloff, then surge to new nominal highs on unprecedented monetary stimulus. | 2024–25 Record Central bank buying >1,000T/yr. Geopolitical fragmentation. Dollar diversification accelerates. |

Correlation & Portfolio Construction
Gold and US equities have maintained a near-zero long-run correlation over 25 years, meaning their price movements have historically had little consistent directional relationship. This characteristic is the mathematical foundation of the portfolio diversification argument for gold.
Why Near-Zero Matters. Correlation is a measure of whether two assets tend to move together or apart, on a scale from +1 (perfect co-movement) to −1 (opposite movement). Gold’s long-run correlation to the S&P 500 has averaged close to zero over the past 25 years.
This draws from the foundational principles of Modern Portfolio Theory. Harry Markowitz demonstrated mathematically in 1952 that combining assets whose returns are not perfectly correlated can reduce the overall volatility of a portfolio without necessarily sacrificing expected return. Gold’s correlation to equities is not fixed, however. It can fluctuate and shift during periods of acute stress. Rolling estimates have varied considerably, sometimes turning briefly positive, sometimes modestly negative, reflecting the changing weight of macro drivers versus liquidity dynamics in any given period.
Gold’s Average Annual Price Correlation to Major Asset Classes
| US Bonds (AGG) | 0.24 |
| Inflation (CPI) | 0.21 |
| Crude Oil | 0.14 |
| Real Estate (REITs) | 0.05 |
| S&P 500 | 0.02 |
| US Dollar Index | -0.33 |
Unlike a US Treasury bond, physical gold carries no counterparty risk.
| 1944 | Bretton Woods pegged the US dollar to gold at $35/oz, making gold the anchor of the post-war international monetary order. |
| 1971 | Nixon suspended dollar-gold convertibility. Western central banks became net sellers, viewing gold as a relic in the era of fiat currency. |
| 2000s | The tide turned. Emerging-market central banks began accumulating reserves in earnest, seeking to diversify away from dollar-denominated assets. |
| 2022 | Freezing of Russian central bank assets highlighted counterparty risk in sovereign bond holdings, accelerating diversification into gold. |
| Today | Gold represents approximately a quarter of global official reserve assets, recently surpassing the euro as the second-largest reserve asset behind the US dollar. |
Five Key Takeaways
- Gold’s 25-year return (~11% annualized) has been broadly comparable to large-cap equities.
- Long-run correlation to the S&P 500 has averaged near zero, the basis of the diversification case.
- Central banks have been structural net buyers, exceeding 1,000 tonnes per year recently.
- Gold produces no income; opportunity cost vs. fixed income is real and should be modeled.
- Correlation benefits can break down in acute liquidity crises, the most critical limitation to understand.
