When Sterling Bank closed its books for the first nine months of 2026, the headline looked like a celebration. Operating income had jumped by 38.13 percent to N307.06 billion, net interest income had surged by 43.94 percent to N205.90 billion, and profit after tax had risen by 20.99 percent. Yet beneath that celebration sat a quieter, more uncomfortable figure: earnings per share had fallen by 11.47 percent. How can a bank make more profit and yet give each shareholder less? That single contradiction captures the entire story of Sterling in 9M 2026. It is a bank that is growing fast, funding itself cheaply, lending aggressively, and earning well, but it is also a bank that is paying a heavy price for that growth in provisions, dilution, and over-dependence on one source of income. The real question for the months ahead is not whether Sterling can grow, but whether it can grow in a way that lasts.
The engine of the performance was net interest income, and it is impossible to understand Sterling without understanding how powerful and how dangerous that engine has become. Net interest income now accounts for 67.05 percent of total operating income, which means that more than two-thirds of everything the bank earns comes from the difference between what it charges borrowers and what it pays depositors. In 9M 2026 that engine worked brilliantly because Sterling sits on a customer deposit base of N3,842.65 billion, a vast pool of cheap funding, including a large share of non-interest-bearing deposits that cost the bank almost nothing. With that funding advantage, the bank could expand its loan book aggressively and still earn a wide margin, and it did. But the same engine that produced the 43.94 percent rise in net interest income also produced the most troubling number in the results: credit loss expense rose by 398.22 percent to N40.28 billion. That is not a rounding error, it is a warning. It tells us that a significant portion of the new lending is already showing stress, that management’s earlier judgment about who would repay has had to be revised sharply upward, and that a large part of the impressive interest income was not true profit at all but income that had to be handed straight back as provisions. In banking, interest income is only as good as the quality of the loan that produces it, and Sterling’s 9M results show a bank that is still learning that discipline.
The challenge of net interest income goes beyond credit risk. It also carries interest-rate risk, which arises from the gap between the maturity of loans and the maturity of deposits. If Sterling lends long and funds short, a rise in rates will squeeze its margin because it must pay depositors more while its loans are still locked at old rates. If it lends short and funds long, a fall in rates will squeeze it in the opposite direction. In a low-rate environment, the squeeze is even worse, because deposit rates cannot be pushed much below zero while loan rates keep falling. This is why a bank that depends on net interest income for 67.05 percent of its earnings is inherently fragile. It is hostage to the central bank, to inflation, to market sentiment, and to the behaviour of its borrowers. Sterling’s strength here is real: its cheap deposit base gives it a cushion that investment banks and fintechs do not enjoy, and its ability to raise capital gives it room to absorb shocks. But that strength will only become lasting value if it is used to be selective rather than aggressive, to price loans for quality rather than for volume, to diversify across retail, secured corporate and SME lending rather than concentrating in risky unsecured exposures, and to build early-warning and recovery systems that use digital data to spot trouble before it becomes a provision. With abundant cheap funding, Sterling does not need to chase high-risk loans to make margin. It can afford to say no, and learning to say no is the next stage of its maturity.
If net interest income is the story of strength that became exposure, fees and commissions are the story of opportunity that is being missed. Net fees and commissions grew by only 10.44 percent to N39.63 billion, a mere 12.90 percent of operating income. For a bank with millions of deposit customers, that is strikingly low. Fee income is the most desirable income in banking for a simple reason: it is stable, it is paid up front, it carries no direct credit or market risk, and it uses very little capital. It is earned from the everyday services customers actually need: transfers, cards, account services, trade finance, foreign exchange services, agency banking, custody and advisory work. When a bank earns well from fees, it does not need to gamble on rates or on risky loans to survive. It has a cushion. Sterling does not yet have that cushion. Its fee growth is lagging its loan growth by more than thirty percentage points, which means that as the bank gets bigger, it is becoming more, not less, dependent on interest income. The challenge of building fees is real: it requires heavy investment in technology, branches, agents, controls and people, it carries operational risk from system failure, fraud and process error, and it faces fierce competition from fintechs and pressure from regulators who cap charges. But Sterling already owns the hardest part of the fee business, which is trust and distribution. It has the licence, the balance sheet, the brand, and above all, the customers. Every deposit account it holds is a potential source of card fees, transfer fees and trade fees, and every SME customer it lends to is a potential user of payments, collections and advisory services. If Sterling can convert its deposit base into a service base, by deepening digital channels, expanding agency banking, and cross-selling to existing customers rather than chasing new ones at high cost, it can lift fees from 12.90 percent to a level where they genuinely balance the income mix. That single shift would do more to stabilize Sterling’s profit than any amount of loan growth, because it would give the bank an income line that does not disappear when rates move or when borrowers default.
Trading income tells a different, quieter story, and in this case the quiet is a strength. Net trading income fell by 6.47 percent to N21.30 billion, just 6.94 percent of operating income. In a year when many banks were tempted to chase trading profits to cover rising loan losses, Sterling showed restraint. Trading is the most volatile income a bank can earn. It comes from buying and selling equities, bonds and derivatives, both as a market-maker for clients and as a proprietary trader for the bank’s own account. It carries high market risk, meaningful credit risk from counterparties, and measurement risk, because the Value-at-Risk models banks use to estimate trading losses are statistical guesses, not guarantees. A long record of trading profit is no protection against a sudden market correction or a single wrong bet, and history is full of banks that were destroyed not by bad loans but by bad trades. Sterling’s low and falling trading share therefore signals discipline. It suggests that management is not using depositors’ money to speculate, and that it understands trading as a service to customers who need foreign exchange, bonds and hedging, rather than as a casino. The opportunity for Sterling is to keep it that way: small, client-driven, tightly controlled, with clear limits, independent risk oversight, and a focus on earning a market-making spread rather than taking large directional bets. If it does, trading will remain what it should be, a useful complement to core banking, not a hidden threat that can wipe out quarters of careful lending work in a single bad week.
Other operating income, which rose by 95.36 percent to N40.23 billion, or 13.10 percent of operating income, played a crucial supporting role in 9M 2026. It helped offset the surge in impairments and allowed profit after tax to rise despite the credit shock. But this is also the most misunderstood line in the results. Other operating income is a residual category, made up of dividends, gains on disposal of assets, rental income, foreign exchange revaluation gains and other one-off items. By nature it is unpredictable, it cannot be budgeted like fees, and it can easily mask weakness in the core business. A bank that relies on it year after year is living on windfalls. The critical interpretation for Sterling is therefore not to celebrate the 95.36 percent jump as if it were recurring, but to use it wisely as a bridge. The windfall should be invested in the two things that create durable value: stronger credit systems that will prevent the next 398.22 percent jump in provisions, and stronger fee technology that will build recurring non-interest income. If the one-off gain is used to fix the core, it becomes a turning point. If it is used to pay for more aggressive lending, it becomes a wasted opportunity.
Beyond the income mix, three weaknesses need to be confronted honestly, because they will determine whether Sterling’s growth creates value or destroys it. The first is provisions. A 398.22 percent rise to N40.28 billion cannot be explained away as prudent conservatism alone. It indicates that appraisal, monitoring and recovery have not kept pace with loan growth, and that the bank must now invest urgently in credit discipline, transparency and early intervention. A bank that confronts its bad loans early recovers more value than one that hides them. The second is cost. Operating costs, from staff to information technology to premises to regulatory charges, are largely fixed in the short term. When income is volatile, costs eat profit quickly. Sterling must use its digital strength to drive efficiency, automating processes, shifting customers to low-cost digital channels, and closing inefficient manual processes, so that cost-to-income falls even when income is under pressure. The third is dilution. Profit after tax rose by 20.99 percent, but earnings per share fell by 11.47 percent because new shares were issued to raise capital. Capital raising is a strength only if the new capital earns a return above its cost. The new equity must now be put to work in quality loans, fee technology and risk systems. If it is, earnings per share will recover and shareholders will be rewarded for their patience. If it is wasted on reckless lending, dilution will become permanent value destruction, and the 9M results will be remembered as the moment the bank grew bigger but not better.
When all these threads are pulled together, the implications for stakeholders become clear, and they are not the same for everyone. For shareholders, value will not come from headline growth alone but from quality growth: fees rising, provisions falling, costs controlled, and return on new equity exceeding the cost of that equity. For depositors, value is safety and service. A bank with a strong deposit base, controlled trading, and balanced income is safer, and if Sterling invests in digital service and operational controls, depositors will get both safety and convenience. For borrowers and small businesses, value is access to credit that is priced fairly and managed responsibly, with support through difficulty rather than aggressive foreclosure at the first sign of trouble. For regulators, value is stability: a bank that manages its interest-rate gap, holds adequate provisions and keeps trading small does not need intervention. For staff, value is a bank that invests in technology and skills, creating higher-skilled jobs in digital, risk and advisory work rather than relying on manual processing. And for the wider economy, value is a bank that channels its enormous deposit base into productive lending and efficient payments rather than into speculation.
Sterling Bank’s 9M 2026 performance, read critically, is therefore both impressive and instructive. It proves the bank can mobilize deposits on a massive scale, grow net interest income faster than almost any peer, raise capital, remain profitable under credit stress, and resist the temptation to gamble in trading markets. It also proves that growth without balance is fragile. The bank now stands at a decisive point where its strengths can be deployed to solve its problems: its deposit strength can make lending selective and sustainable, its customer base can make fees a real second engine, its discipline can keep trading safe, and its one-off gains can fund the systems that prevent the next credit shock. If Sterling makes those choices, the 9M 2026 results will be remembered not as a peak but as a turning point, the moment a fast-growing bank became a well-balanced bank, and a well-balanced bank became a value-creating bank for shareholders, depositors, borrowers, staff, regulators and the economy it serves.
