Gold Mine Hedging
Also: Producer hedging, Forward selling, Mine hedging
Gold mine hedging is the practice by gold producers of selling future output through forward contracts at a fixed price in order to protect themselves against falling gold prices.
Gold mine hedging is a risk management tool used by gold producers to stabilise their revenues. In it, the mine commits to delivering a certain amount of output at a price agreed today – the so-called forward price – at a later date. This mechanism partially decouples the mine's revenue from the current gold price and protects against price falls between production and sale.
How it works
The classic hedge is set up using gold forwards or futures on the COMEX or in the OTC (over-the-counter) market:
- The mine sells future gold deliveries (e.g. 50,000 troy ounces in 12 months) via a forward contract.
- The agreed forward price is typically above the current spot price, because interest rates and storage costs (contango) are priced in.
- If the market price falls before delivery, the mine delivers at the contractually fixed price – the loss is borne by the counterparty (the bank).
- If the price rises, the mine forgoes the gains above the agreed rate.
Forward price = spot price × (1 + interest rate − gold lease rate) ^ t
Hedge book – the sum of all open positions
The totality of all a mine's open forward sales is called its hedge book. In the 1990s, many producers built up massive hedge books – Barrick Gold, for example, hedged millions of ounces. When the gold price surged strongly after 2001, these books became enormous burdens: the mines had to deliver far below the market price. The result was an industry-wide de-hedging wave (buying back open positions), which drove the gold price even higher.
Advantages and disadvantages at a glance
| Aspect | Advantage | Disadvantage |
|---|---|---|
| Planning certainty | Fixed revenues for investors | No upside when the price rises |
| Creditworthiness | Banks finance mines more easily | Mark-to-market losses when the price rises |
| Industry impact | Stable business model | Large hedge book weighs on the spot price |
Significance for investors in mining shares
Anyone investing in mining shares needs to know the mine's hedge book: a high degree of hedging dampens the price leverage (the so-called leverage) relative to the gold price. Unhedged mines react more strongly to price movements – both upwards and downwards. You can follow the current gold price at gold price; historical price developments help to put hedging decisions into context.

In brief
Gold mine hedging protects producers against price falls, but at the same time limits their participation in gains when prices rise. For investors in mining shares, the hedge book is a key valuation criterion.
