Clearing is the process that confirms, records and prepares a financial transaction for settlement after the buyer and seller have agreed to it. It checks that both sides submitted matching details and that the buyer has the funds, works out what each party owes, and makes sure the securities reach the buyer and the cash reaches the seller. Clearing happens between the trade and the final exchange of money or assets. Settlement is the moment that exchange actually takes place.

The term applies across finance. It describes how stock and derivatives trades pass through clearing firms and clearinghouses, and it also describes how banks process checks and electronic payments drawn on one another.

How clearing works in securities and derivatives

The steps vary by market, but a trade on an exchange generally moves through the same stages.

1. Trade capture. The exchange matches a buy order with a sell order and reports the executed trade, including price, quantity, instrument and the parties’ clearing members.
2. Comparison and validation. The trade details from both sides are compared. If they agree, the trade is accepted for clearing. The clearing firm also confirms that the buyer has enough cash or broker-provided margin to pay for the position.
3. Novation. In centrally cleared markets, the clearinghouse replaces the original contract between buyer and seller with two new contracts. It becomes the buyer to every seller and the seller to every buyer, acting as the counterparty to both sides.
4. Netting. The clearinghouse offsets each member’s purchases and sales in the same security, so the member delivers or receives only the net quantity and net cash.
5. Margin. For derivatives, and to a degree for securities, the clearinghouse collects collateral and marks positions to market, calling for more collateral when positions lose value.
6. Settlement instructions. The netted obligations are passed on for settlement, when cash moves to sellers and securities move to buyers’ accounts.

When trades fail to clear

A trade that cannot be cleared because the two sides reported conflicting information, such as a different price or quantity, is called an out trade. The counterparties are first given the chance to resolve the discrepancy on their own and resubmit the corrected trade. If they cannot agree, the dispute goes to the relevant exchange committee for arbitration.

A trade that is never cleared carries settlement risk: one party could deliver its side and not receive the other. Unresolved breaks can also cause accounting errors and real losses.

Exchange vs. clearinghouse

An exchange is where orders meet and trades are executed. The clearinghouse handles everything after execution: confirming, guaranteeing, netting and preparing settlement. Sometimes both sit inside the same group; the Chicago Mercantile Exchange, for example, operates CME Clearing. In U.S. equities, trades from many exchanges clear through the National Securities Clearing Corporation (NSCC), a subsidiary of the Depository Trust & Clearing Corporation (DTCC). LCH is one of the largest derivatives clearinghouses, alongside CME.

Who participates

Only clearing members deal directly with a clearinghouse. These are typically large banks and broker-dealers that meet capital and operational standards and contribute to the clearinghouse’s default fund. A retail broker that is not a clearing member uses a clearing firm to clear its customers’ trades. The clearing firm holds customer funds and positions, checks buying power and stands behind the trades toward the clearinghouse. The broker the customer sees is often called the introducing broker.

Clearinghouses charge a clearing fee for their services. In many brokerage accounts this fee is already folded into the commission or into the broker’s pricing, so investors rarely see it as a separate line.

The default waterfall in central clearing

A central counterparty (CCP) guarantees cleared trades, so it needs a plan for when a clearing member cannot meet its obligations. That plan is the default waterfall, an ordered sequence of resources used to cover losses. Layers vary by rulebook, but the typical order is:

1. The defaulting member’s margin. The collateral the failed member posted is used first.
2. The defaulting member’s default fund contribution. Its share of the mutualized guarantee fund comes next.
3. The CCP’s own capital (“skin in the game”). A slice of the clearinghouse’s own resources, which gives it an incentive to manage risk well.
4. Non-defaulting members’ default fund contributions. The surviving members’ pooled contributions absorb losses beyond that point.
5. Further assessments and recovery tools. Many rulebooks allow the CCP to call additional funds from surviving members, up to a defined cap, and to use other recovery measures.

Before drawing on these layers, the CCP usually tries to close out or auction the defaulter’s positions, which limits the size of the loss to be covered.

Clearing in banking

In banking, clearing is the process of settling payment obligations between banks, so that money from a check or transfer moves from the payer’s bank to the payee’s bank.

Check clearing

When a bank receives a check drawn on another institution, it can present the check directly to that bank, exchange it through a local clearinghouse, use a correspondent bank, or send it through the check collection services of a Federal Reserve Bank. According to the Federal Reserve, most checks the Reserve Banks receive are collected and settled within one business day.

This is why funds from a deposited check may sit on hold: your bank needs to confirm with the paying bank that the funds exist, and then it has to receive them.

ACH and electronic clearing

The Automated Clearing House (ACH) network is an electronic system for transferring funds between accounts at different institutions, used for payroll direct deposit, bill payments and transfers between individuals and businesses. An ACH payment carries the account and routing numbers of the sending and receiving accounts, essentially the same information as a paper check, and ACH payments are cleared in batches rather than one by one.

Netting between banks

Bank clearing aims to reduce the money that actually changes hands. Here is a hypothetical example: Bank A owes Bank B $2 million for checks cleared during the day, and Bank B owes Bank A $1 million. Instead of two transfers totaling $3 million, Bank A pays Bank B the $1 million difference. Across many banks and many items, this multilateral netting cuts settlement amounts sharply.

A clearing bank participates directly in interbank clearing systems, or clears payments or securities on behalf of other firms. The Bank of New York Mellon, for example, is a major clearing bank for securities and the U.S. government securities market.

Example: clearing a futures trade

Assume, as a hypothetical case, that a trader buys one stock index futures contract and the initial margin to hold it overnight is $6,160.

• At the trade: The clearing firm sets aside $6,160 of the trader’s account as a good-faith deposit. That amount cannot be used for other trades while the position is open.
• Daily mark-to-market: Suppose the contract loses $1,000 in value by the close. The clearing firm debits the trader’s account by $1,000 and the clearinghouse credits the same amount to the side that gained. If the account falls below the maintenance margin level, the trader receives a margin call to restore it.
• Counterparty protection: The trader never needs to know who sold the contract. If the seller cannot pay, the clearing firm and the clearinghouse, backed by margin and the default waterfall, honor the trade.

For a stock purchase, the mechanics are simpler but follow the same idea. The broker’s clearing firm confirms you have the cash or margin, the trade is netted with other trades through the clearinghouse, and settlement delivers the shares to your account. U.S. stock trades now settle on T+1, one business day after the trade date. Your account may show the shares immediately, but the cash from a sale is not considered settled until that settlement date.

Clearing vs. settlement and other terms people confuse

Clearing vs. settlement. Clearing covers matching, validating, netting and calculating obligations. Settlement is the final transfer that completes the deal. A trade can be cleared and still be awaiting settlement.

Clearing vs. clearance. In securities usage, “clearance” often means the delivery of securities against payment that completes settlement, while “clearing” covers the broader confirmation and netting process.

Cleared vs. available funds in banking. A bank may make part of a deposit available before the check has fully cleared. If the check later bounces, the bank can reverse the credit, so spending funds before clearing carries that risk.

Clearing account. In accounting, a clearing account is a temporary holding account used to park amounts until they are allocated to their proper accounts, such as payroll or suspense items. It should return to zero once entries are reclassified. In brokerage, the phrase can also refer to the account held at a clearing firm.

Clearing instruction. This refers to the details that tell a clearing firm or bank how to process a transaction: the accounts, the counterparty’s clearing member and the delivery or payment instructions.

Why clearing matters, and its limitations

After the 2008 financial crisis, regulators in the U.S. and Europe required many standardized over-the-counter derivatives, such as interest rate swaps, to be centrally cleared to reduce counterparty and settlement risk.

The model has trade-offs:

• Concentration risk. A CCP concentrates risk from many members in one entity, so the failure of a major clearinghouse could spread across the whole market. That is why CCPs are tightly regulated and maintain waterfalls and recovery plans.
• Liquidity demands. Margin calls can be large and sudden in volatile markets, forcing members and their clients to raise cash quickly.
• Delays for end users. Check holds and settlement cycles mean money is not always usable at the moment it appears in an account.
• Costs. Clearing fees and the expense of posted collateral add to the price of trading, even when bundled into a commission.

FAQs

The Bottom Line

Investors, traders and anyone depositing checks deal with clearing, usually without seeing it. Clearing protects each side from a counterparty that fails to pay, but it also brings check holds, margin calls and fees that are often bundled into commissions. Treat newly shown shares or deposited funds with care until settlement or clearing is complete, since a bounced check can be reversed and unsettled sale proceeds are not yet final.
