A silver trader can be right about next month’s price and still run out of money this week. The reason is how futures accounts handle gains and losses along the way.
Mark-to-market is the process of revaluing an open position as prices change and settling the resulting gains or losses. In exchange-traded futures, this happens through regular clearing and settlement cycles, rather than waiting until the contract expires.
For anyone following gold or silver, it helps explain why a sharp move can force leveraged traders to act even when no physical bullion changes hands.
What Mark-to-Market Actually Means
When someone buys a gold futures contract, its value changes with the futures price. Mark-to-market turns those changes into financial adjustments between participants.
The official daily settlement price provides a common reference. It is determined under the exchange’s rules and may differ from the final trade displayed on a live chart. Trading can continue after the settlement price has been established.
For a position held from the previous session, the day’s gain or loss generally comes from the difference between two settlement prices, multiplied by the contract size. For a new trade, the entry price also matters.
In futures, this adjustment is called settlement variation. In its explanation of mark-to-market, CME Group describes how daily settlement transfers gains and losses instead of allowing unpaid obligations to build up until expiry.
The futures position remains open as cash adjustments occur.
A Two-Day Example Using Silver Futures
A trader buys one standard COMEX silver futures contract at $70.00 per ounce. It represents 5,000 ounces.
On the first day, the contract settles at $70.40. The trader gains $0.40 per ounce, or $2,000 across the contract. On the second day, settlement falls to $69.90. That day’s loss is measured from $70.40, not from the original entry price.
| Point in time | Silver price | Daily account effect |
|---|---|---|
| Entry | $70.00 | — |
| Day 1 settlement | $70.40 | +$2,000 |
| Day 2 settlement | $69.90 | −$2,500 |
| Total since entry | — | −$500 |
The net result is a $500 loss, following a gain and then a larger debit. The position need not close for those changes to matter.
The contract size is what turns a small move per ounce into a substantial dollar amount. Standard gold contracts represent 100 ounces and standard silver contracts 5,000. Percentages alone hide how much cash is at stake.
Why Daily Revaluation Matters for Margin
Futures traders normally post collateral instead of paying the full notional value of the metal represented by a contract. That saves capital but allows losses to erode collateral quickly.
Suppose a trader has $18,000 in account equity and loses $3,000 through the daily settlement process. Equity falls to $15,000. The consequences depend on the maintenance requirement and broker rules.
If the remaining equity is insufficient, the trader may receive a margin call. They may need to deposit cash, reduce exposure or face liquidation. Brokers can also demand action during the trading day rather than waiting for the next published settlement.
The important point is that a trader’s conviction about next month’s gold price cannot pay today’s collateral obligation. A position can be profitable in the end only if the account survives the moves before then.
How Long and Short Positions Are Affected
Mark-to-market does not favor buyers over sellers.
A trader holding a long gold futures position benefits when that contract rises. A short seller gains when it falls. If the price moves the other way, each suffers a loss that feeds into the settlement process.
For example, a $50 rise in a standard 100-ounce gold contract means a $5,000 gain for a long and a corresponding $5,000 loss for a short, before fees and other account effects.
A heavily leveraged short seller may then have to buy back futures to reduce exposure. During a falling market, financially stressed longs may sell to close positions. Either response can strengthen an existing market move, although the initial price change was not caused by the accounting process itself.
That distinction is useful when sudden rallies are described as short covering or sharp declines as forced selling. Neither explanation is automatic.
What Happens When Markets Turn Volatile?
The consequences become more visible when volatility increases. A $3 move in a standard silver futures contract changes its value by $15,000. For someone holding several contracts with limited spare capital, that can be an immediate funding challenge.
Some traders respond by adding money. Others hedge, reduce positions or exit entirely. If many accounts face pressure, their orders may accelerate the move.
But a sharp decline in open interest does not prove that every closing trade was forced. Outstanding contracts can fall because traders take profits, cut risks voluntarily or move out of an expiring contract month.
To judge whether deleveraging might be taking place, it helps to consider price, trading volume and positioning together rather than reading one indicator in isolation.
Futures Settlement vs. Owning Physical Bullion
An investor who buys a fully paid gold bar also sees its market value change every day. That is an economic gain or loss, but no exchange clearinghouse normally transfers cash out of the owner’s account because the bar is worth less than yesterday.
With futures, mark-to-market works differently. Gains and losses lead to cash adjustments within the clearing system even when the trader leaves the contract open. This reduces the build-up of unpaid obligations between market participants.
A futures liquidation is not necessarily a physical sale. A trader can close a silver position without taking delivery of any bars, while a private investor can continue holding bullion through a market decline without a futures-style collateral call, provided the metal was purchased without borrowing.
Financial pressure in futures and actual availability of physical metal are related market issues, but they are not interchangeable.
How Investors Can Use This Information
When gold or silver moves sharply, daily settlement helps explain how price action can become a funding problem. It is worth asking three questions:
- How large was the move? Consider dollars per contract, not just the percentage on a chart.
- Did outstanding positions decline? Falling open interest may show exposure being removed, without revealing why every trade closed.
- Who was positioned beforehand? Concentrated speculative exposure can make an adverse move more disruptive.
Weekly COT positioning data help answer the third question by showing how groups such as Managed Money were positioned. These figures are snapshots, not a live record of margin calls or daily cash flows.
The lesson is that mark-to-market turns a change in futures prices into an immediate financial obligation or benefit. Knowing how that happens makes leverage, account risk and the difference between futures and physical bullion much easier to understand.
Frequently Asked Questions
What Is Mark-to-Market in Futures Trading?
Mark-to-market is the regular revaluation of an open futures position using the current or official settlement price, with gains and losses credited or debited to the trader’s account.
How Often Are Futures Positions Marked to Market?
Exchange-traded futures are typically marked to market daily. The official settlement price is used to calculate the gain or loss on open positions for that settlement period.
How Is a Mark-to-Market Gain or Loss Calculated?
The price change is multiplied by the contract size. For an existing position, the daily calculation generally compares the current settlement price with the previous settlement price.
How Does Mark-to-Market Affect Margin?
Profits increase the equity supporting a futures position, while losses reduce it. If losses push account equity below the required maintenance level, the trader may need to provide additional collateral.
Can Mark-to-Market Trigger a Margin Call?
Yes. Repeated or large daily losses can reduce account equity below the applicable margin requirement, which may lead to a margin call or position reduction.
Does Mark-to-Market Affect Long and Short Positions Differently?
The mechanism is the same for both. Long positions gain when futures prices rise and lose when they fall, while short positions experience the opposite effect.
Is Mark-to-Market the Same as an Unrealized Gain or Loss?
Not exactly. With futures, daily price changes are financially settled through the mark-to-market process even while the position remains open. This differs from simply watching the market value of an unleveraged asset rise or fall without any daily cash settlement.
