This paper analyses five drivers of bank profitability and their combined impact on banks and the overall economy.
The low profitability of many European banks has become a constant feature since the financial crisis. Low profitability among European banks reflects a range of factors that vary across countries and across banks, including the weak economic environment in Europe, stubbornly low net interest margins, high levels of non‑performing loans, high cost to income ratios, the impact of regulatory reform, and – for some banks – a business model that relied too heavily on the good times continuing without serious interruption.
This paper analyses the key drivers of bank profitability both theoretically and empirically, using the same data set as the KPMG Peer Bank metrics.
The profitability of many European banks is low, and is expected to remain so. The average return on equity of all banks in the EU stands at around 3 percent, and at around 5 percent for larger banks. This is well below the cost of capital – which is generally reckoned to be in the region of 10‑12 percent. Metrics based on equity prices suggest that investors remain wary of the true value of banks’ assets and pessimistic about future profitability.
Low profitability has real consequences, some of which we highlight in this paper – most importantly, low profitability weakens the ability and willingness of banks to finance the wider economy, which may in turn weaken the overall economy and place further downward pressure on both profitability and the value of bank assets.
We focus here on five key drivers of bank profitability, and the difficulties facing banks in attempting to turn these around into positive drivers of profitability.
Net interest margin – Downward pressure on interest margins has a particularly marked impact on banks that rely relatively heavily on interest rather than non‑interest income.
Non-performing loans (NPLs) – The increase in NPLs has a negative impact on profitability through a variety of channels, including unpaid interest on loans, raising provisions against impaired assets, and realising losses when assets are sold or restructured.
Cost to income ratios – Cost to income ratios have remained stubbornly high across EU banks since the financial crisis. Financial innovation and technological progress may offer opportunities to reduce costs over the longer term, but for many EU banks this appears to be a distant and uncertain horizon.
Business model – Business models could be an important driver of profitability, especially during a period when there have been major divergences in the performance of different types of banking activity.
Regulatory reform – Regulatory reform has had a major impact on banks’ funding costs through higher capital requirements, with additional cost and income pressures through liquidity requirements. The price of the greater resilience and resolvability achieved through these reforms is a large deadweight impact on banks’ return on regulatory capital.
Our analyses suggest that a bank seeking to improve its return on regulatory capital by one percentage point would need to:
It will not be easy for banks to achieve these improvements, not least at a time when net interest margins are under increasing downward pressure from lower interest rates; the weak economic environment may lead to a higher rate of non‑performing loans; regulatory requirements continue to push up banks’ funding costs; and competitive pressures from existing banks, new entrant banks and non‑banks remain strong.
