Ghana's bank profit record hides a tax story
Ghana's banks posted GH¢2.5bn in profit by February 2026. That's a record. The March Monetary Policy Report says all income lines grew, just slower than last year. If you're a shareholder, that looks good. If you're the Ghana Revenue Authority, it's a different picture.
The interest rate tailwind
The Bank of Ghana held the policy rate at 15.5% in February 2026. That rate is the engine behind those profits. Banks collect wide margins on loans to the government and to whoever can still borrow. Net interest income swells when the central bank keeps rates high. But high rates also choke private sector credit. Businesses aren't borrowing to expand. They're borrowing to survive, if they can borrow at all.
Non-performing loans (NPLs) are the hidden risk. When the economy slows and rates stay elevated, more loans go bad. The record profit today could be a provision problem tomorrow. GCB and other lenders may look profitable on paper while their loan books quietly deteriorate.
The tax collection gap
The government's tax revenue is not matching bank profits. Ghana's informal sector is massive. Traders, artisans, and small service providers pay almost nothing in income tax. The GRA has run multiple tax amnesties, but they don't fix the structural problem. VAT refund backlogs are another symptom. Businesses wait months for refunds, which destroys trust and encourages evasion. The cost of compliance, filing, audits, penalties, falls hardest on small firms that can't afford accountants.
This isn't a mystery. It's a choice. The state has not invested in simple, low-cost collection systems for the informal economy. Meanwhile, banks benefit from high government borrowing needs that push up bond yields. The same high rates that enrich banks drain the private sector.
What investors should watch
Bank profits and economic growth (GDP) are moving in opposite directions. That divergence never lasts. Expect one of two outcomes: either the central bank cuts rates, which will compress net interest margins and hit bank earnings, or the government tightens fiscal policy to reduce borrowing, which slows the economy further and raises NPLs.
Return on equity (ROE) for Ghanaian banks looks strong now. But it's fragile. The real question is not whether banks can make money in a high-rate environment. It's whether they can survive the unwind. If you hold bank stocks, watch the NPL ratio and the policy rate. If you invest in Ghanaian bonds, watch the tax-to-GDP ratio. That number is too low. The government will have to raise more revenue somewhere, higher corporate taxes, more targeting of the informal sector, or a new amnesty that won't work.
None of this means bank profits are fake. Just that they come from a specific, temporary environment. When the environment changes, and it will, the profit story will change too.
