European banks saw their best first-half since 1997, but maintaining returns will be a challenge

European banks experienced a robust first half in 2024, with the Stoxx 600 Banks index surging over 28%—its strongest H1 performance since 1997—driven by improved profitability from higher interest rates, significant cost-cutting, strong investment banking returns, and a surge in M&A activity. Despite this outperformance and ongoing consolidation efforts, including Santander's acquisition of TSB and UniCredit's strategic interests, analysts caution that the sector is now "relatively fully valued," suggesting limited upside for the second half and potential risks from loan loss provisions or increased defaults.

Analysis

European banks have delivered their strongest first-half performance since 1997, with the Stoxx 600 Banks index surging over 28%, driven by a confluence of factors that have been belatedly priced in by the market. The primary catalyst has been a structural improvement in profitability following the exit from a decade of ultra-low interest rates, a shift that has proven more impactful on margins than recent rate fluctuations. This macro tailwind has been amplified by firm-specific actions, including widespread cost-cutting and restructuring programs at institutions like HSBC, UBS, and Deutsche Bank. Furthermore, a robust M&A environment is acting as a significant valuation driver; Santander's acquisition of TSB, alongside contested bids involving BBVA/Sabadell and UniCredit's interests in Banco BPM, highlights a push for scale. Standout performers such as Societe Generale and Commerzbank, both up approximately 80% year-to-date, have benefited from this dynamic, although UniCredit's CEO has now signaled that Commerzbank's sharp re-rating makes it too expensive to acquire. Despite this momentum, which is also supported by strong investment banking returns and German lenders' exposure to a booming defense sector, a note of caution has emerged. Analysts, such as those from Morningstar, now view the sector as "relatively fully valued," struggling to identify new catalysts for significant further profit growth and highlighting potential risks from deteriorating credit quality or an increase in defaults in the second half.

Key Decisions for Investors

• Given the sector's significant 28% H1 rally and analyst commentary on full valuations, investors should consider trimming exposure to top performers like Societe Generale and Commerzbank to realize profits.
• Monitor M&A developments closely, as deal activity remains a key catalyst; potential takeover targets may still offer event-driven upside, whereas acquirers such as BBVA face notable execution and regulatory risks.
• Shift focus from broad sector exposure to individual stock selection, prioritizing banks with successful restructuring execution, unique growth exposures like the defense sector, or superior balance sheet management.
• Scrutinize upcoming earnings reports for guidance on net interest margins in a stabilizing rate environment and for any signs of rising loan loss provisions or default rates, which represent the key risks for the second half.
