Netting

What Is Netting?

Netting combines several amounts that point in opposite directions into a single figure. Instead of settling each transaction separately, the parties add up what they owe each other and exchange only the net balance. The idea appears in trade settlement, derivatives contracts, and even within a single investor's account.

The basic calculation is:

Net amount = total amounts owed to you − total amounts you owe

If the result is positive, the other party pays you. If it is negative, you pay them.

How It Works

Netting reduces the number and size of payments and deliveries. Suppose two firms trade with each other many times in one day. Without netting, each trade would need its own payment. With netting, the trades are combined, so only one payment, from the side that owes more, may be needed. A clearing house applies a similar approach by becoming the counterparty to both sides of a trade and netting the obligations of its members.

Netting also matters when a party defaults. Netting agreements in derivative contracts allow the remaining obligations to be combined into one amount owed, instead of requiring a separate claim on each contract.

Why It Matters to Investors

For individual investors, netting is often invisible, but it has a few effects. Because less cash and fewer securities must move between institutions, netting can reduce settlement risk. It can also limit how much exposure a broker or counterparty has to a single failing firm, which affects the safety of assets held on your behalf.

Netting is also familiar in your own account. Gains and losses from positions closed in the same period are often combined to produce a net result. How this is treated for capital gains tax depends on the type of asset and on local tax rules, so the specifics vary.
