- PwC Says Ghana’s Banks Need New Growth Engines as Interest Margins Come Under Pressure
Ghana’s banking industry is approaching a potentially defining shift in its profitability model as declining interest rates threaten to compress margins and force lenders to look beyond traditional interest income for sustainable growth, according to PwC.
In its latest Ghana Banking Survey, the professional services firm argues that the next phase of competition will be determined less by banks’ ability to benefit from wide interest margins and high-yielding financial assets and more by their capacity to reinvent business models, develop alternative revenue streams and make deliberate choices about where they can compete most effectively.
The warning follows a period in which Ghanaian banks benefited from elevated yields across parts of the financial system. High interest rates and substantial holdings of government and other debt securities supported earnings even as institutions navigated the effects of the Domestic Debt Exchange Programme, exchange-rate volatility and wider macroeconomic instability.
That operating environment is now changing as inflationary pressures ease and interest rates move lower. For banks, the strategic challenge is therefore shifting from protecting existing earnings to identifying how they can generate sustainable returns when the unusually favourable yields of the previous cycle are no longer available.
“Whether as factories, distributors, advisors, enablers, funders, segment specialists, or scaled conglomerates, banks will need to make clear choices about where they can win, invest in the capabilities that support those choices, and build business models capable of generating value beyond the interest-rate cycle,” PwC said.
The assessment goes to the heart of a structural question facing Ghana’s financial sector. Falling rates can be broadly supportive of the economy because they reduce borrowing costs, stimulate credit demand and encourage investment, but the same process can weaken bank profitability where lenders have depended heavily on interest-bearing assets and government securities.
The composition of earnings may therefore become increasingly important. Institutions capable of expanding fee and commission income, transaction banking, payments, wealth management, advisory services and other non-interest businesses could be better positioned to absorb pressure on net interest margins.
Digitalisation is likely to become central to that transition because Ghana’s rapid adoption of electronic payments and mobile financial services has intensified competition for customer transactions. Banks are no longer competing only with one another, but with fintech companies and technology-led financial platforms capable of delivering payments and other services at relatively low marginal cost.
That creates a dual challenge. Banks must invest sufficiently in technology to remain relevant, but those investments will only strengthen profitability if they translate into higher transaction volumes, deeper customer relationships, lower operating costs or commercially viable new products.
PwC argues that the strategic choices institutions make should also reflect the purposes for which individual banks were established and their underlying corporate values. “Banks that move earliest and most decisively may be best placed to shape the industry’s next chapter,” the firm said.
The need for repositioning comes despite a stronger operating backdrop. Ghana’s banks benefited in 2025 from easing inflation, greater exchange-rate stability, stronger economic growth and an improved fiscal environment, helping to support asset growth, liquidity and overall earnings.
Balance sheets expanded as deposit mobilisation strengthened, with part of the additional liquidity directed towards debt securities and part towards lending. Core banking revenues remained resilient, while trading income and fees and commissions also supported profitability.
Yet the same macroeconomic stabilisation that is strengthening bank balance sheets could gradually weaken some of the earnings streams that proved particularly lucrative during the high-rate cycle.
Lower inflation and declining market rates typically reduce nominal yields across financial assets, meaning banks may have to generate substantially greater volumes of business or diversify revenue if they want to maintain previous profitability levels.
That shift could encourage lenders to compete more aggressively for quality private-sector borrowers. For Ghana’s economy, that would be significant because businesses, particularly SMEs, have long complained about expensive credit and limited access to long-term financing.
If government securities become relatively less attractive as yields decline, private-sector lending could become more compelling. Banks with strong deposit franchises, effective risk-management systems and reliable borrower data may be able to increase lending while still preserving acceptable risk-adjusted returns.
The danger is that institutions respond to falling investment income by pursuing loan growth too aggressively. Rapid credit expansion can weaken asset quality if underwriting standards deteriorate, particularly in an economy where businesses remain exposed to exchange-rate movements, energy costs, taxation and fluctuations in domestic demand.
That makes data and customer segmentation increasingly important. Banks capable of using transaction histories and other digital information to assess borrowers more accurately could expand credit without proportionately increasing bad-loan risk, turning better risk pricing into a major competitive advantage.
Scale will remain important, particularly because larger institutions can spread technology and regulatory costs across broader customer bases. But PwC’s reference to “segment specialists” suggests smaller banks do not necessarily need to compete across every part of the market and may instead find sustainable positions in SMEs, trade finance, affluent banking, corporate advisory or other targeted niches.
The emerging environment could therefore produce greater differentiation within Ghanaian banking. Some institutions may pursue mass-market digital scale, others could deepen corporate and transaction banking, while more specialised lenders may focus on selected sectors or customer groups where they can price risk and deliver services more effectively than larger rivals.
What appears increasingly difficult is relying on the interest-rate cycle itself as a long-term strategy. Ghana’s banks have emerged from several years of severe macroeconomic disruption with stronger liquidity and renewed profitability, but the next test will be whether those gains survive a more normalised economic environment.
For bank executives and investors, the key question is therefore shifting from how much profit institutions are making today to how those profits are generated and whether those earnings can withstand lower rates. PwC’s message is not that a profitability crisis is inevitable, but that business-model adaptation has become increasingly urgent.
As Ghana moves towards a potentially more stable and lower-rate environment, the banks best able to convert deposits, technology, customer relationships and data into diversified and recurring income streams are likely to emerge stronger.
The era in which high interest margins could do much of the heavy lifting may be fading, and what replaces it could reshape the competitive hierarchy of Ghanaian banking for years to come.
