Sterling Bank’s H1 2026 Gamble: Bigger, Richer,and Riskier

Banking is maturity transformation. You borrow short from depositors and lend long to borrowers. It is profitable, but invariably risky. The job of Asset and Liability Management, or ALM, is to acquire funds cheaply, allocate them wisely, and stay liquid, solvent, and within regulatory rules while maximizing profit. Sterling Financial Holdings Company Plc’s unaudited results for the six months ended 30 June 2026 show a bank that chose growth in a storm. In a period of punishing interest rates, currency volatility, and rising loan defaults across Nigeria, Sterling went big. It pulled in more deposits, expanded its loan book, raised fresh capital, and delivered higher profits. But that expansion came with a cost, and the bill is now sitting on its balance sheet. The numbers force a hard question: in chasing growth, did Sterling do enough to protect the five people who matter most to any bank — depositors, borrowers, shareholders, regulators, and employees?

The verdict from the results is mixed, and it starts with size. Sterling grew total assets by 19.3% to ₦4.67 trillion, and customer deposits by 21.1% to ₦3.62 trillion. That tells you the public still trusts the bank with their money. Management put those deposits to work. Net interest income jumped 41% to ₦137.4bn because the bank was able to lend at higher rates faster than it had to pay for deposits. Profit before tax rose 22% to ₦55.5bn. To fund this and stay ahead of regulators, Sterling also raised capital, pushing total equity up 27.7% to ₦547.7bn. On paper, this is a bank that mastered the first half of ALM: get the money in, and make it earn.

But the second half of ALM — managing the risk — is where the cracks appeared. The very act of “lending long” bit back. While loans grew 13.8%, the bank’s credit loss expense exploded by 357% to ₦23.85bn. That is not a small uptick. It means a growing number of borrowers are struggling to pay, likely under pressure from inflation and FX volatility. At the same time, rising interest rates punished the bank’s investment portfolio. Sterling recorded a ₦25.1bn fair value loss on debt instruments, which wiped out much of its other comprehensive income and cut total comprehensive income almost in half year-on-year. Shareholders felt it too. Even though profit rose, earnings per share fell from 89k to 77k because the new capital diluted existing shares. Growth was delivered, but it was costly and it diluted returns.

The operating environment made these problems worse and created new threats. High interest rates, while good for lending margins, also made funding more expensive and destroyed the value of bonds the bank held. Inflation pushed operating costs up 23.8%, with staff costs alone rising 40.4%. Regulators watching these numbers will be pleased with the stronger capital and liquidity — Sterling also parked more money in “Due from Banks,” up 81.8%, as a buffer — but they will be deeply concerned about the speed of asset quality deterioration. For borrowers, the immediate impact is more access to credit, but the next impact will be tougher terms and higher prices as the bank tries to protect itself. For employees, the 40% jump in personnel expenses signals investment and job security, at least for now.

So how did Sterling try to balance these trade-offs? It used three strengths. First, it won the liability side. Deposit growth shows customers still believe in the franchise, and that cheap funding is the lifeblood of ALM. Second, it raised equity early, before losses forced it to. That capital cushion is what will keep regulators comfortable and depositors safe if impairments rise further. Third, it diversified income. Other operating income more than doubled, which means the bank is reducing its reliance on risky lending and building fee-based revenue that doesn’t depend on the credit cycle.

In the end, Sterling Bank satisfied depositors and regulators in the short term, gave borrowers more access, and invested in employees. But it asked shareholders to accept dilution and lower comprehensive income in exchange for future growth. The bank proved it can grow in a tough environment. The open question is whether it can now control the risks that came with that growth. If Sterling reins in credit losses and stabilizes its investment book, this period will be remembered as a bold expansion. If not, the very strategy that created profit in H1 2026 will become the reason the bank struggles in H2. In banking, that is always the deal: profit today, or risk tomorrow.
