CSCS is Nigeria's central securities depository, responsible for clearing, settling, and safekeeping all securities traded on the NGX. Every investor in the Nigerian stock market needs a CSCS account, identified by a unique Clearing House Number (CHN). CSCS handles the back end of every trade, moving shares from seller to buyer and coordinating cash settlement.
Think of CSCS as the plumbing of the Nigerian stock market. When you buy shares through your broker, CSCS is the entity that actually moves those shares into your account and confirms the transaction. Without it, there is no settlement. Your broker handles the order, the exchange matches it, but CSCS makes it real.
CSCS operates as the central securities depository (CSD) for the Nigerian capital market. All securities traded on the NGX are held electronically in CSCS. Physical share certificates still exist for some older holdings, but new transactions are entirely dematerialised. CSCS also handles the deduction of withholding tax on dividends before they're credited to investor accounts.
The company itself is publicly listed on the NGX. It earns revenue from settlement fees, transaction charges, and various market infrastructure services. It's one of those businesses that benefits directly from market activity: more trades mean more fees.
You can't open a CSCS account directly. You need to go through a SEC-licensed stockbroker. The process works like this: you choose a broker, complete their account opening forms (identity documents, proof of address, passport photographs, BVN), and the broker initiates your CSCS account. You'll receive a Clearing House Number (CHN), which is your unique identifier across the entire Nigerian capital market.
Your CHN is permanent. If you switch brokers, your CHN stays the same. You can have accounts with multiple brokers but they'll all be linked to the same CHN. This is similar to how your BVN follows you across banks. Fintech investment platforms handle the CSCS account opening as part of their onboarding, which has made the process much faster than the traditional route of visiting a broker's office.
In April 2026, CSCS announced enhancements to its Account Opening System (AOS) aimed at faster account creation and better data processing. The goal is to reduce friction for new investors, particularly those coming through digital platforms.
CSCS manages the settlement cycle for all NGX trades. For years, Nigeria operated on T+3, meaning it took three business days after a trade for shares and cash to settle. In November 2025, the market moved to T+2, bringing it in line with most developed markets.
The next step is T+1, which CSCS plans to launch on 29 May 2026. This would mean trades settle the next business day. If it happens on schedule, Nigeria will be ahead of most European markets on settlement speed. The US only achieved T+1 in May 2024, and it was treated as a major industry effort.
Faster settlement reduces counterparty risk (the chance that the other side of your trade fails to deliver) and frees up capital more quickly. For retail investors, the practical effect is that you'll be able to sell newly purchased shares sooner. For the market as a whole, it should improve liquidity and reduce the capital that brokers need to keep in reserve.
Every trade on the NGX involves several layers of fees. Brokerage commission typically runs 0.5% to 1.75% of the trade value. NGX and SEC fees add 0.3% to 0.45%. CSCS settlement fees are 0.06% to 0.3% (inclusive of VAT). There's also a stamp duty of 0.075% on purchases. Add these up and a round trip (buy and sell) can cost 2% to 4% of the trade value.
These fees are higher than what investors in developed markets pay. Discount brokerages in the US charge zero commission. Even in South Africa, total transaction costs are lower. For long-term investors who trade infrequently, the impact is manageable. For active traders, it's a meaningful drag on returns.
Dividend payments also attract CSCS processing charges, though these are small relative to the dividend amount. The bigger deduction is the 10% withholding tax, which CSCS withholds before crediting dividends to investor accounts.
A CSCS number (also called a CHN, or Clearing House Number) is your unique identifier in the Nigerian securities market. It's assigned when you open a CSCS account through a stockbroker or fintech investment platform. You only have one CHN, even if you use multiple brokers. To get one, sign up with any SEC-licensed broker or platform (most SEC-licensed brokers and fintech platforms handle this). You'll need your BVN, a valid ID, proof of address, and passport photos. Most fintech platforms complete the process digitally within 24 to 48 hours.
As of November 2025, Nigeria operates on T+2 settlement, meaning trades settle two business days after execution. Buy shares on Monday, they're in your CSCS account by Wednesday. CSCS is preparing to move to T+1 (next business day settlement) on 29 May 2026. Before the recent changes, Nigeria operated on T+3 for years, and before that, settlement could take weeks. The shift to faster settlement is a significant infrastructure improvement that reduces risk and improves capital efficiency for all market participants.
Total transaction costs typically range from 1% to 2.5% per trade, broken down as follows: brokerage commission (0.5% to 1.75%), NGX and SEC fees (0.3% to 0.45%), CSCS settlement fees (0.06% to 0.3%), and stamp duty (0.075% on purchases). A round trip (buying and selling) can cost 2% to 4% in total. These costs are higher than in developed markets and should be factored into investment decisions, particularly for short-term trading. Some fintech platforms offer lower commission rates than traditional brokers, but the regulatory fees are fixed regardless of which platform you use.
Yes. Because your shares are held centrally at CSCS under your CHN, you can transfer them between brokers. The process involves submitting a transfer request to your current broker, who then instructs CSCS to reassign the shares to your account with the new broker. Your CHN doesn't change. The timeline can vary; some transfers complete in a few days, others take longer depending on the brokers involved. Both brokers may charge a transfer fee. If you're unhappy with your broker's service or fees, transferring is straightforward in principle, though the execution can sometimes involve bureaucratic delays.
