Gold
Gold is the world's oldest financial asset — a non-yielding store of value that humans have used as money for roughly five thousand years. In modern markets it competes with US Treasuries for the role of 'risk-free reserve asset,' rises when real interest rates fall, and serves as an inflation hedge and dollar-debasement insurance. Central banks have been net buyers of gold every year since 2010.
It's the oldest financial asset in continuous use. Roughly 5,000 years of human history have featured gold as a store of value, a medium of exchange, and a hedge against political risk. The properties that made it valuable in 3,000 BC — durable, divisible, fungible, scarce, recognizable — still apply. Modern markets price gold against the real interest rate, against the dollar, against political risk, and against the willingness of central banks to maintain unilateral control of their reserves. When any of those factors shift meaningfully, gold reprices — sometimes by hundreds of dollars per ounce in a single month.
What it measures
Gold trades in two main markets: the spot physical market (centered in London via the LBMA — London Bullion Market Association) and the futures market (centered in New York via COMEX, part of CME):
We track via Yahoo's GC=F ticker — front-month COMEX gold futures. The headline price moves with the futures contract; the physical spot price (LBMA fix) typically tracks within a small basis. Gold trades 24 hours a day in spot markets (the LBMA fixing is twice daily at 10:30 and 15:00 London time, but actual trading is continuous), and roughly $200 billion of paper gold notional changes hands daily.
The "troy ounce" is the standard pricing unit — slightly heavier than the regular ounce most Americans imagine (1 troy oz = 31.1 grams; 1 regular ounce = 28.35 grams).
Why it matters
Two angles.
The portfolio-insurance angle. Gold has historically had low correlation with stocks and bonds — meaningfully negative correlation during equity bear markets. The classic "Permanent Portfolio" (Harry Browne, 1981) and modern risk-parity allocations both include 5-25% gold for diversification benefits. During the 2008 financial crisis, gold rose from $700 to $1,000+ as equities collapsed. During the 2022 inflation shock, gold held up well as both stocks and bonds fell. The diversification benefit isn't perfect (gold can also fall in stressed markets when investors need cash, as briefly happened in March 2020), but the long-run correlation profile is genuinely attractive.
The reserve-asset diversification angle. Central banks hold roughly 36,000 tonnes of gold as official reserves — about 17% of all gold ever mined. They have been net buyers every year since 2010, and the pace accelerated dramatically after 2022 (when US sanctions on Russia froze its dollar reserves). Annual official gold purchases now run 1,000+ tonnes — about 25-30% of total mine production. This is large enough to be a major price driver: a 1,000-tonne annual demand source on a market with ~4,500 tonnes of total annual supply (mine + scrap) is meaningful. The trend toward reserve diversification away from dollars is structural and ongoing — and gold is the primary beneficiary.
What moves it, and what it moves
Moves gold:
- Real interest rates (negatively correlated). When 10-year TIPS yields fall, gold rises; when they rise, gold falls. This is the strongest single relationship in gold pricing.
- The US dollar (inverse correlation). A stronger DXY makes gold more expensive for non-dollar buyers and reduces demand.
- Central bank purchases. Persistent, structural, currently elevated.
- Inflation expectations (positive correlation). Gold is widely held as an inflation hedge; rising inflation expectations support gold.
- Geopolitical risk. Wars, sanctions, currency crises, political uncertainty — all drive flight-to-safety flows into gold.
- Indian and Chinese physical demand. Jewelry and investment demand from these two countries is a substantial fraction of global demand (~30-40%); their economic and cultural cycles matter.
Gold moves:
- Mining-stock equity prices (gold miner ETFs like GDX track physical gold with a roughly 2x beta).
- Jewelry market pricing globally.
- Central bank reserve composition (slowly — the dollar share of reserves has fallen from ~70% in 2000 to ~58% in 2024, with gold and yuan picking up the difference).
- Inflation expectations (slightly — gold's price level is one input into market-implied inflation forecasts).
- Bitcoin pricing (intermittent correlation; both compete for "store of value" capital).
A worked example: the 2020-2024 bull market
Gold entered 2020 around $1,520/oz. The COVID crisis produced an immediate flight-to-safety rally — gold reached $2,067 in August 2020, an all-time high at the time. The drivers were synchronized: real rates falling to deeply negative levels as the Fed cut to zero, the dollar weakening (DXY fell from 102 in March to 90 by December), and pandemic-era uncertainty driving investment demand.
Gold then traded in a $1,700-$1,950 range through 2021-2022 — the war in Ukraine produced spikes but they reversed as risk appetite returned.
The next leg of the bull market began in late 2023. Central bank purchasing accelerated; the dollar weakened modestly from its 2022 highs; the Israeli-Palestinian conflict added geopolitical premium. Gold crossed $2,000 sustainably for the first time in early 2024, then $2,500 by mid-2024, and $3,000 in early 2025. The peak as of mid-2025 was approximately $3,150 in April-May 2025, coinciding with the Moody's US downgrade and renewed tariff-policy uncertainty.
The 2020-2025 move — from $1,500 to $3,150 — was a roughly 2.1x in five years, an annualized return of approximately 16%. This outperformed the S&P 500 over the same period in price terms (the S&P 500 was up roughly 80% over those five years, vs. gold's 110%).
The current cycle, and the open question
The structural question for gold:
- Continued debasement / diversification rally — central bank gold purchases continue at 1,000+ tonnes/year; the dollar's reserve share continues to slowly erode; gold trades $3,500-4,000 over the next 2-3 years. This is the "structural shift" view.
- Mean reversion to real-rate-driven framework — once central bank buying normalizes and the dollar stabilizes, gold returns to trading primarily on real-rate dynamics. If TIPS yields stay 1.5-2% real, gold settles in the $2,000-2,500 range — meaningfully below current levels.
- Spike on acute stress — gold remains the cleanest portfolio insurance asset for systemic financial events. A US debt-ceiling crisis, a major sovereign-credit episode, or a serious geopolitical escalation could push gold to $4,000-5,000 briefly.
Watch points: World Gold Council quarterly demand reports; central bank gold purchases (monthly IMF data, with ~3-month lag); 10-year TIPS yield (the closest single proxy for gold's opportunity cost); the spread between gold and Bitcoin (when gold outperforms Bitcoin meaningfully, suggests institutional rather than retail flow); and Indian and Chinese gold imports (monthly customs data is a high-frequency proxy for physical demand).
