Narrow Interest Spread: Implications for Banking Profitability in Nepal

As of Saun End, 2082 (Mid-August 2025), Nepal’s banking sector is operating with a weighted average deposit rate of 4.02% and a weighted average credit rate of 7.76%, leaving an interest spread of about 3.74%. This spread—the difference between what banks earn on loans and what they pay on deposits—is the primary source of profitability for banks. While a margin close to 4% appears sustainable, it also raises questions about the future of banking profitability in Nepal amid rising risks and changing market dynamics.

From a positive perspective, the current spread allows banks to maintain stable earnings. With deposits growing to 118% of GDP and credit at 91.31% of GDP, the sector is deeply integrated into the economy. A near 4% spread provides sufficient room for banks to cover operating costs, absorb provisions, and deliver returns to shareholders. For commercial banks in particular, the large deposit base and diversified loan portfolios ensure that profitability remains intact even under moderate pressure.

However, the spread is narrowing compared to previous years when double-digit lending rates and lower deposit costs created wider margins. The growing dominance of fixed deposits (48.14% of total deposits) means banks are paying more for funds, squeezing net interest margins. At the same time, rising Non-Performing Loans (NPLs at 4.62%)increase provisioning requirements, directly eating into profits. Smaller institutions such as development banks and finance companies, which already have thinner customer bases and higher risk exposures, are particularly vulnerable to margin compression.

Looking forward, banks face a dilemma. To retain depositors in a competitive environment, they must keep offering attractive rates, but this drives up funding costs. Lowering lending rates to stimulate credit demand, especially for SMEs and households, could further reduce spreads. Conversely, keeping lending rates higher risks slowing down borrowing and dampening growth.

In the broader picture, a narrowing interest spread reflects the maturing of Nepal’s banking sector. Profitability will increasingly depend on fee-based income, digital banking services, and operational efficiency, rather than just traditional interest margins. This transition may reshape how banks operate in the coming years.
