Yair Hamburger has been Chairman of Harel Insurance Investments & Financial Services from the day it was incorporated in 1982 — more than forty years in the same chair. The company is now one of Israel's big-four insurers. He built it.

The Business Story

The Hamburger family business in Israel began in 1935, when Ernst and Margot Hamburger — German-Jewish émigrés — founded the Hamishmar Insurance Agency in Mandatory Palestine. The business operated under British rule, survived the founding of the State of Israel, and built a multi-decade book of life and non-life insurance policies across the Israeli middle class.

Yair Hamburger was born in 1946 — two years before Israeli statehood. He studied economics and political science at the Hebrew University of Jerusalem. He joined the family business and entered into the operational structure his parents had built.

In 1975, the family established Harel Insurance Company as the operating insurance carrier, with Yair as CEO. Seven years later, in 1982, both Harel Insurance Company and the original Hamishmar Insurance Agency were brought under a new holding company — Harel Hamishmar Investments Ltd, later renamed Harel Insurance Investments & Financial Services Ltd. Yair was named Chairman of the holding company at its incorporation. He has held the position continuously since.

Over the following four decades, Harel expanded by both organic growth and a series of disciplined acquisitions. Health insurance became the largest single-category position in the group — anchored by the 2015 merger of Dikla Insurance Company (health insurance and long-term care) into Harel. The combined platform built Harel into Israel's largest health insurer with approximately 40 percent market share.

By 2017 the group reported NIS 185 billion in assets under management across insurance, pension funds, provident funds, mutual funds, and financial services. By 2024, group revenue had grown to approximately $7.4 billion. The group employs thousands of insurance professionals and runs separate subsidiaries for credit insurance (ICIC, joint with Euler Hermes), mortgage insurance (EMI), and Turkish operations (Turk Nippon Sigorta).

In 1999, under Israeli corporate governance rules separating chairman and CEO roles at large public companies, Yair Hamburger stepped down as CEO of the insurance company while retaining the chairmanship of the holding company. The day-to-day insurance company CEO role has been held by professional managers in the period since.

Why He Matters in Israel

Three reasons.

First, the size of the underwriting book. Roughly two in five Israelis are insured by a Harel product. Insurance is unglamorous, but the cash-flow position of an insurer in a national market the size of Israel is structurally very strong. Hamburger has been the controlling family figure inside that flow for forty years.

Second, the multigenerational arc. The family has been continuously in Israeli insurance since 1935 — almost a decade before the State of Israel existed. Across nine decades and four generations, the Harel platform has compounded steadily without the rise-and-fall arcs that have characterized many other Israeli family dynasties. The succession to the next generation — through Ben Hamburger at Harel Finance — is being executed inside the existing operational architecture rather than through asset transfers and litigation.

Third, the industry-association role. As Chairman of the Israel Insurance Association since 2016 and the Association of Life Insurance Companies, Hamburger has been the senior public-facing voice of the Israeli insurance industry across the recent decade of regulatory tightening — Solvency II adoption, IFRS 17 transition, the unwinding of cross-financial-and-non-financial holdings under the Concentration Law.

What the Company Does Today

Harel Insurance Investments & Financial Services is publicly traded on the TASE (HARL). The Hamburger family and Manor family — through G.Y.N. Financial Consulting and Investment Management 2017 LP — hold approximately 48.86 percent of the company. The public holds the remainder.

Harel operates across health, non-life, and life insurance; pension and provident fund management; mutual fund management; and investment portfolio management through Harel Finance Holdings (the wholly owned financial services arm). Subsidiaries include Veritas, Harel Yedidim Insurance Agency, Career Army Savings Fund, Harel 60+ retirement products, Turk Nippon Sigorta (Turkey), and others.

The group is an anchor investor in Ace Capital Partners, the Israeli defense-tech venture capital fund established in August 2024 by a former Israeli Air Force commander.

Legacy and Influence

Yair Hamburger sits in a small group of Israeli founders who have run a single major financial institution continuously for forty years. Few comparable continuity records exist anywhere in the Israeli economy. Even fewer involve a multi-generational family business that crossed the pre-state, founding, and modern eras of the country intact.

The Harel platform is also one of the cleanest examples of disciplined, retained-earnings-funded, conservative-leverage capital compounding in Israeli financial services. There were no high-leverage acquisitions of cross-sector pyramids. There were no currency speculations. There were no prison sentences. There was insurance underwriting, executed steadily, for ninety years.

Why He Matters Now

The next decade of Israeli savings, pensions, and long-term insurance is being shaped by IFRS 17, by ongoing solvency tightening, by demographic aging, and by digital distribution. Harel is one of three or four firms that will set the institutional response. Hamburger remains the family voice in those decisions.

The succession architecture — Ben Hamburger at Harel Finance, professional managers running Harel Insurance Company, the family bloc at the top of the holding company — is one of the more deliberate next-generation handoffs in Israeli family-controlled finance. How it executes over the next decade will be a case study in itself.
