Al Rajhi did not begin as a bank, and for most of its life it was not one. It began as a boy at a market stall in Riyadh in the late 1930s, changing currency for pilgrims and for the migrant workers who needed to send wages home. That trade — unglamorous, high-volume, built entirely on trust and on knowing who was good for the money — is where the institution's real foundations were laid, and it is the part of the story that has never been recorded properly.
Saleh bin Abdulaziz Al Rajhi started it. His brothers Sulaiman, Abdullah and Mohammed joined through the 1940s, and by 1947 there was a formal exchange shop. The year the bank itself treats as its founding is 1957. In 1978 the family's separate operations were consolidated into one company. Only on 29 June 1987, by Royal Decree No. M/59, did it become a Saudi joint-stock bank; it listed on the Saudi exchange on 1 December 1988 and took the shorter name Al Rajhi Bank in 2006.
What makes it unusual is not the size, though the size is remarkable. It is that a family business built on a manual, relationship-based trade converted itself into a fully Sharia-compliant bank at national scale, then into one of the most heavily digital banks in the world — 14.8 million active digital users and roughly a billion transactions a month — without ever adopting the interest-based model that every comparable institution was built on. Nobody has explained in public how that conversion was managed.
There is also a story here that has nothing to do with banking. In 2009–2011 Sulaiman Al Rajhi divided his personal fortune in two: half to his family, half into a permanent charitable endowment, formalised by a deed issued in mid-May 2011. Forbes had estimated him at between $5.9 and $7.7 billion. The endowment funds a university, a hospital and several mosques in Qassim. He is alive, at ninety-seven.
What follows is the seventy years as they can be documented from public sources — and it says plainly where the record stops, which is earlier and more often than an institution of this size should allow.
