The Banking Oligopoly

Five banks control roughly 98% of Israeli banking assets and posted NIS 29.5B in record 2024 profits. On May 6 2026, the Competition Authority declared them a concentration group — opposed publicly by the Bank of Israel. The defining Israeli financial-regulation conflict of 2026.
Five banks control approximately 98% of Israeli banking sector assets. The top two — Hapoalim and Leumi — hold roughly 48% of all assets and just over 50% of public deposits. The five together generated NIS 29.5 billion (~$7.8 billion) in combined net profit in 2024 — a record year. On May 6, 2026, the Israel Competition Authority formally declared the top five banks a concentration group. The Bank of Israel publicly opposed the move as "extreme and disproportionate" — the defining Israeli financial-regulation conflict of 2026.
The Concentration
The five banks — Bank Hapoalim, Bank Leumi, Israel Discount Bank, Mizrahi Tefahot Bank, and First International Bank of Israel — control approximately 98% of Israel's ~NIS 3 trillion in banking sector assets. The US top five hold roughly 45% of US banking assets. The UK top five roughly 70%. Israel is among the most concentrated banking markets among developed economies. In the mortgage market, three banks issue roughly 81% of all Israeli mortgages. Full context: The Five-Bank Market After Strum and The Shekel Mortgage Book as Macro Indicator.
The 2024 Profit Cycle
The most profitable year in modern Israeli banking history. Combined net profit: NIS 29.5 billion. Both Leumi and Hapoalim posted all-time individual records. The profits were driven by the rate environment — the BOI's 2023–2024 tightening cycle raised lending rates while deposit rates lagged. The BOI introduced a relief scheme requiring NIS 3 billion in consumer relief by 2027 — a partial response that did not address the structural conditions.
The May 6, 2026 Declaration
Israel Competition Authority Director-General Michal Cohen formally declared the top five banks a concentration group. Directives take effect May 6, 2027. Three conditions: deposit price discrimination is prohibited; customer-switching friction must be eliminated (banks must proactively contact customers near deposit renewal, enable online transfers); standalone product access must be offered without forcing customers to maintain a current account.
The Bank of Israel Dissent
The Bank of Israel described the declaration as extreme and disproportionate and argued its own prudential reforms already addressed the competitive concerns. The split — both regulators agree on the diagnosis, disagree on the tool — is the most visible Israeli inter-regulator conflict in recent memory.
The Neema Fine — April 2025
Hapoalim and Discount were each fined NIS 40 million for minority holdings in fintech startup Neema — a marker that incumbent bank equity in fintech startups would be treated as competition-restricting going forward. Context: Bit, PayBox and the Battle for Israeli Consumer Payments.
