proprietary account
Proprietary Account is a bank's own trading account, holding money that belongs to the bank itself, not to any customer.
In plain English
Whose money is actually sitting in that account? That is the question a proprietary account answers, and it is not a trick question at all.
Every bank holds thousands of accounts for customers like you and me, but it also keeps its own accounts, funded with the bank's own capital, used to trade shares, bonds, currencies or other instruments for the bank's own profit. That is a proprietary account. No customer's ₦50,000 or ₦5,000,000 sits in there. It is the bank's money, doing the bank's business, carrying the bank's risk.
Think of a Nigerian bank like Zenith or GTBank. Alongside serving millions of customers, it may also buy government treasury bills or foreign currency positions using funds set aside as its own capital, hoping to make a gain when prices move favourably. If that trade goes well, the profit belongs entirely to the bank, not to depositors. If it goes badly, the loss is the bank's problem too, not something calmly passed on to your savings account.
In the United Kingdom, this kind of activity used to be called proprietary trading, and it became famous after the 2008 financial crisis, when regulators asked hard questions about banks gambling with money while also holding ordinary people's deposits. Rules like the Volcker Rule in America, and similar restrictions elsewhere, were built to separate this risky, self interested trading from the safer business of looking after customer funds.
For the everyday Nigerian reading this, the point is reassurance mixed with awareness. Your salary account, your savings, your fixed deposit, these are customer accounts, protected and separate. The proprietary account is the bank playing with its own chips at its own table, and understanding that difference helps you read banking news with a clearer head.
A bank sets aside ₦2,000,000,000 of its own capital in a proprietary account and uses it to buy dollar denominated bonds, hoping the naira weakens and the bond value rises in naira terms. Any profit or loss stays with the bank, never touching customer deposits.
Questions people ask
Can my personal savings ever be moved into a proprietary account?
No, that would be a serious breach of banking rules. Customer funds and the bank's own trading funds are kept legally and operationally separate, and any mixing of the two is exactly what regulators watch for.
Do Nigerian banks still do proprietary trading?
Yes, within limits set by the Central Bank of Nigeria, banks can trade instruments like treasury bills, bonds and foreign exchange using their own capital, though heavy restrictions exist to stop this risk taking from threatening customer deposits.
Why should an ordinary person even care about proprietary accounts?
Because it helps you understand banking headlines. When you read that a bank lost money on a trading position, it usually means its proprietary account took a hit, not that customer savings were touched.
