How Is the Gold Price Determined? What the Spot Market, COMEX and Central Banks Don't Tell You
The gold price is not set by supply and demand alone. Three mechanisms you probably have never heard of drive most of the daily price movement.
Most people think gold's price rises when inflation rises, falls when interest rates rise, and goes up in crises. All of that is partly true and profoundly incomplete. Let me explain what actually determines where gold trades at any given moment.
The London Bullion Market: Where the Price Is Set
The gold price is formally set twice daily in the LBMA Gold Price auction, administered by ICE Benchmark Administration. At 10:30 AM and 3:00 PM London time, an algorithm matches buy and sell orders from participating banks to find a clearing price. This auction sets the benchmark that flows through to every gold price you see — your jeweller, your ETF, your futures contract.
The physical gold market clears largely through London. When a central bank buys 50 tonnes, they call a bullion bank. When a mine sells its production forward, they call a bullion bank. The bullion banks intermediate almost all of this flow, and their net positioning at any moment influences intraday price direction.
COMEX Futures: Where Speculation Lives
The Chicago Mercantile Exchange's COMEX division trades gold futures contracts worth 100 troy ounces each. Daily futures volume regularly exceeds 1,000 tonnes — approximately 40% of annual global mine production trading every single day. The majority of these contracts are never delivered physically. They are financial instruments.
The speculative positioning on COMEX — tracked weekly in the CFTC Commitment of Traders report — is one of the most reliable leading indicators of gold price direction. When managed money (hedge funds, CTAs) are heavily long, gold is often due a correction. When they are heavily short, a rally is often building. I track this report every Friday.
Real Yields: The Variable That Dominates Everything
The single most important driver of gold price over 6-18 month horizons is US real interest rates — the nominal rate minus inflation. Gold pays no yield. When real yields are negative (inflation exceeds nominal rates), the opportunity cost of holding gold is zero or negative — you are not giving up real return by holding it. This is why gold surged to records in 2020 when real yields hit -1%. It is why gold fell in 2022 when the Fed raised rates aggressively. Watch the 10-year TIPS yield. When it falls below zero, gold typically rises.
Key Takeaways
- The LBMA auction sets the daily benchmark price; COMEX futures reflect speculative positioning
- Real interest rates (nominal minus inflation) are the dominant driver of gold's direction over months
- Central bank buying — particularly from China, India and Turkey — has been the structural demand story of 2022-2026
- CFTC Commitment of Traders data is a reliable leading indicator of short-term gold price reversals
