Understanding how spot bullion is priced requires peering behind retail charts into the interplay between mining economics, interbank liquidity pools, and derivatives positioning.
1. Mining Economics & The AISC Floor
The All-In Sustaining Cost (AISC) represents the total cost required for mining companies to extract, process, and sustain gold production per ounce. When spot prices approach aggregate industry AISC levels ($1,350 to $1,450/oz in modern mining operations), production halts and supply contractions establish an unbreakable cyclical floor.
2. The Interbank Physical Arbitrage
Physical arbitrageurs continuously monitor the spread between COMEX futures contracts in New York and LBMA physical spot in London. When physical demand exceeds available vault inventory, physical premiums surge, forcing futures prices higher to restore equilibrium.
