The Five-Bank Market After Strum
The Strum Committee reforms were supposed to break the Israeli banking duopoly. A decade on, the market is more contested at the edges but the core structure is intact.
Banking · Israel · Updated June 28, 2026
The Strum Committee, reporting in 2016, was the most consequential structural intervention into the Israeli banking system in a generation. The committee ordered the divestiture of the credit-card franchises that the two largest banks — Hapoalim and Leumi — had historically operated as captive in-house businesses, and reshaped the regulatory framework for Israeli retail banking. A decade on, the five-bank concentration that defined Israeli banking still defines it — but with a new layer of digital and credit-card competitors that did not exist in 2016. The structural shift is real but partial.
The Five Banks
The Israeli banking system is structurally dominated by five commercial banks. Bank Hapoalim and Bank Leumi are the two large universal banks, each with assets in the range of NIS 700–800 billion. Mizrahi Tefahot is the third, the mortgage-and-religious-community-oriented franchise with assets around NIS 400 billion. Israel Discount Bank is the fourth, the historically Sephardi-community bank with assets around NIS 400 billion. First International Bank of Israel (FIBI) is the fifth, smaller at around NIS 200 billion.
The five together hold approximately 95% of Israeli banking system assets. The next tier of banks — Union Bank (merged into Mizrahi in 2020), Pepper (digital), One Zero (digital), Bank Yahav, Bank Massad — together hold the remaining share. The concentration ratio is high by OECD standards and has been the subject of structural concern across multiple regulatory cycles.
The Strum Committee Mandate
The Strum Committee was established in 2015 to address the dominance of Hapoalim and Leumi in retail banking and credit cards. The structural problem was clear. The two largest banks owned the two largest credit-card companies — Isracard (Hapoalim) and Leumi Card. The credit-card businesses operated as captive distribution channels for the parent banks, with effective consumer choice limited by the concentration of issuance.
The committee's principal recommendation was forced divestiture. Hapoalim was required to sell Isracard. Leumi was required to sell Leumi Card. The divestitures were structured to be completed by 2020 with regulatory consent on the acquiring entities.
The Divestitures
Leumi Card was sold to Warburg Pincus in 2019 for approximately NIS 2.5 billion and rebranded as Max. The transaction created the first independent Israeli credit-card franchise of meaningful scale, operating outside the universal-banking architecture.
Isracard was spun out via a 2019 listing on the Tel Aviv Stock Exchange at an initial market capitalization of approximately NIS 3.5 billion. The post-IPO Isracard operates as a publicly listed independent credit-card and consumer-finance franchise.
The third major Israeli credit-card franchise, CAL (Israel Credit Cards), is owned by Israel Discount Bank and Bank Mizrahi Tefahot together. CAL was outside the Strum forced-divestiture framework but the broader regulatory environment has applied pressure toward greater operational independence.
The Digital Bank Wave
Parallel to the Strum framework, the Israeli regulator authorized digital banking licences for the first time. Pepper, launched as a digital subsidiary of Bank Leumi in 2017, was an early move. One Zero, launched as the first fully independent digital bank in Israel in 2021 under Amnon Shashua-led founding capital, was the structural breakthrough.
One Zero received its banking licence from the Bank of Israel in 2019 and entered commercial operations in 2022. The bank has built a deposit base in the single-digit billions of shekels, focused on a digital-native client experience, with no branch network. The operational economics of One Zero remain a subject of debate — digital banks globally have struggled to demonstrate sustainable profitability at sub-scale deposit bases.
Pepper remains a subsidiary of Bank Leumi. The structural question is whether Pepper has been a defensive move — preventing customer migration to fully independent digital competitors — or a genuine operational innovation that resets Leumi's retail cost structure.
The Mortgage Franchise Question
Mizrahi Tefahot's structural position as the dominant Israeli mortgage franchise has not been substantially altered by the post-Strum environment. The bank holds approximately 35% of the Israeli mortgage market, double the share of any competitor. The mortgage concentration is one of the most structural single-line dominance positions in the Israeli financial system.
The post-2022 Israeli interest-rate cycle has reshaped the mortgage economics. Israeli mortgage rates moved from historic lows below 3% to ranges above 5%. The volume of new mortgage origination has compressed. The Mizrahi position has remained dominant in the smaller market.
The Concentration Question After Strum
The structural question that motivated Strum — whether Israeli banking concentration produces consumer outcomes worse than what a more competitive system would deliver — has not been definitively resolved by the post-Strum decade. Spreads on Israeli retail banking remain elevated relative to OECD averages. The credit-card competition introduced by Max and Isracard has improved consumer pricing on some products but has not collapsed the structural rent that the five banks extract from the Israeli household sector.
Subsequent regulatory cycles — the Israeli Securities Authority's open-banking framework, the Bank of Israel's payment-system modernization, the Knesset's periodic anti-trust pressure on banking fees — have applied incremental pressure but not produced another Strum-scale structural intervention.
What 2026 Tracks
Four threads matter. First, the trajectory of One Zero and any new digital banking entrants — whether the digital layer reaches operational scale or remains structurally subscale. Second, the open-banking framework and the question of whether API-driven competition reshapes the deposit and lending markets. Third, the FX and cross-border payment competition from non-bank providers like Wise and the Israeli fintech cohort. Fourth, the broader regulatory environment and whether a post-Strum committee is constituted to address the next layer of structural concentration questions.
The Strum Committee broke the credit-card duopoly. It did not break the five-bank market. The five-bank market remains the structural reality of Israeli banking, with new competition operating at the margin rather than at the core.
