Clearing & settlement

Its role in the system

The invisible “back office” of the markets: once a trade is struck, this is where it is guaranteed that the buyer receives the securities and the seller the money. A central counterparty (CCP) becomes the buyer to every seller and the seller to every buyer, a depository records who owns what, and a custodian keeps investors' assets safe. These are private operators; the state oversight of them sits in the “Capital markets and infrastructure supervision” zone.

Functions

1. Clearing — working out mutual obligations after trades: who owes what to whom; netting collapses thousands of trades into a handful of payments.
2. Central counterparty (CCP) — steps into the middle of every trade and guarantees it will be performed even if one side goes bankrupt (🇬🇧 LCH, 🇩🇪 Eurex Clearing, 🇺🇸 CME Clearing, NSCC within DTCC). 🇨🇳 In China all of these roles sit in a single body: China Securities Depository and Clearing (CSDC) is at once the central counterparty and the depository for every mainland exchange. 🇯🇵 Japan also clears centrally but keeps the record apart: Japan Securities Clearing Corporation (JSCC) clears all of the country's exchange trades, while rights to the securities are held at the JASDEC depository.
3. Settlement — the final exchange: the securities move at the depository, the money through the central bank's payment system, simultaneously, on the principle of delivery versus payment (DvP).
4. Recording and safekeeping — central securities depositories (CSDs: 🇺🇸 DTC, 🇪🇺 Euroclear, Clearstream) record rights to securities; custodians (BNY, State Street) hold funds' assets, collect dividends and coupons and process corporate actions.
5. Prime brokerage — a package of services for hedge funds: credit against securities (margin), stock lending for short sales, clearing and reporting (Goldman Sachs, JPMorgan, Morgan Stanley).
6. Crypto custody — safekeeping private keys for institutional investors: “cold” wallets, multi-signature, MPC technology (Fireblocks, BitGo, Anchorage, Coinbase Custody).

What makes it special

• How it earns: clearing and settlement fees, safekeeping fees (a share of the value of assets), interest on client cash, securities lending. It is a business of scale and thin margins — volume and reliable technology win.
• The default waterfall and compulsory clearing: in case a member goes bankrupt, a CCP holds a queue of buffers — that member's own margin, its contribution to the default fund, part of the CCP's own capital, and the contributions of other members. The main tool is the daily demand to post more margin (a margin call): whoever does not pay on time is closed out. After the 2008 crisis the G20 agreed to clear standard over-the-counter derivatives through CCPs (🇪🇺 EMIR, 🇺🇸 Dodd-Frank), and in 2023 🇺🇸 the SEC adopted a phased move to central clearing of US government bond trades — as a result several CCPs have become “too important to fail”.
• A shorter cycle means less risk and more pressure: 🇺🇸 the United States moved from T+2 to T+1 (settlement on the next business day) on 28 May 2024; 🇪🇺 the EU (Regulation 2025/2075), 🇬🇧 Britain and 🇨🇭 Switzerland move on 11 October 2027. Fewer days means less open risk, but less time to fix a mistake, especially for foreign investors who also have to buy the currency. 🇨🇳 China has long run something shorter but lopsided: CSDC credits the shares to the buyer on the trade day itself while the cash passes the next day (T+1), and a share bought today cannot be sold until the next trading day — a brake on intraday speculation. 🇯🇵 Japan stays on T+2: shares are recorded at the JASDEC depository, and the money finally moves in the Bank of Japan's BOJ-NET system.
• Settlement without a central agent: on a blockchain, delivery and payment can be folded into a single smart contract — either both tokens (the security and the money) move together or neither moves at all (“atomic” DvP). Then neither a central counterparty nor several days of waiting is needed: settlement is final within seconds and available around the clock. The price is the loss of netting: every trade has to be paid in full, so more cash and more securities have to sit on the accounts (🌍 the BIS makes exactly this point). There is no default fund and no waterfall either — nobody to reverse a mistaken transfer or to close out a bankrupt member's positions, and the collateral is priced on the same chain. So far these are pilots: 🇺🇸 DTCC has run its Project Ion ledger alongside the classic system since 2022, and it is the classic system that remains the definitive record; 🇨🇭 SDX, licensed by FINMA in September 2021, trades and safekeeps tokenised securities and, in Project Helvetia III, settles digital bonds against wholesale digital francs issued by the Swiss National Bank; 🇧🇪 Euroclear issued the World Bank's first digitally native notes on its DLT platform in October 2023; 🇬🇧 Fnality has settled sterling payments since December 2023 with money held in an account at the Bank of England. 🇪🇺 The EU opened a dedicated regime for such systems (the DLT pilot regime, since March 2023), but only three operators have been authorised — ESMA itself concluded that the regime's thresholds are too tight.
• Geopolitics inside a depository: it is at Belgium's Euroclear that most of the Russian central bank's reserves in the EU are frozen, and the income from investing them is being channelled into loans to Ukraine.

Why it matters

If the settlement link fails, trades hang in the air: the buyer does not get the securities, the seller does not get the money, and the bankruptcy of one participant drags others down the chain. A CCP concentrates the risk of an entire market in a single point — which is why it has to be extraordinarily reliable.
