SABB folded RBS-backed Alawwal into HSBC-linked SAB, Saudi Arabia's third-largest bank

The Saudi British Bank, 40% owned by HSBC, and Alawwal Bank, 40% owned by Royal Bank of Scotland through its 2007 ABN AMRO purchase, began merger talks in April 2017. RBS had been trying to sell its stake for years as it retreated from international operations. In May 2018 the boards agreed a non-binding exchange ratio valuing the deal at SAR 18.6bn (about $5bn) and creating a bank with around $77bn of assets - the kingdom's third-largest, and its first major banking tie-up in almost two decades, part of the consolidation that came with Vision 2030.

Getting it done took three years. The boards approved the merger in October 2019, with estimated savings of 10 to 15 per cent of the two banks' combined 2017 cost base, and the statutory merger completed in March 2021: SABB absorbed Alawwal's assets and liabilities, with Alawwal shareholders receiving 0.485 SABB shares per share. The combined bank had SAR 257bn of assets, SAR 195bn of deposits, SAR 168bn of customer loans, revenues of SAR 10.9bn and more than a million retail customers, with HSBC the largest shareholder. RBS, by contrast, used the deal to leave the market cleanly.

The merged bank, rebranded Saudi Awwal Bank (SAB), went on compounding: for the first half of 2026 it reported net profit after zakat of SAR 4.42bn ($1.17bn), up 4% year on year, on operating income of SAR 7.28bn, with HSBC still in place as strategic partner and Lubna Olayan chairing the board.

Third-largest Saudi bank: SAR 257bn assets, SAR 10.9bn revenues; 10-15% cost savings targeted; 1H 2026 net profit SAR 4.42bn ($1.17bn), up 4% y/y

Both foreign parents wanted opposite things and the merger gave each one: HSBC a bigger consolidated presence in a growth market, RBS a dignified exit as it retreated from international banking.

Saudi Arabia was pushing banks to consolidate for scale under Vision 2030, and the regulator SAMA was willing to shepherd an untested merger structure through a three-year approval process.

A statutory share-swap merger let two mid-size banks build the cost base of one - 10 to 15% of combined costs - without a cash buyout that would strain capital ratios.

Scale in deposits and a corporate book gave the combined bank pricing power and the balance sheet to underwrite Vision 2030 project finance.

Cross-shareholder mergers work when each parent gets what it came for: one gains a consolidated vehicle in a growth market, the other gets a clean exit from it.

The merger became the template for Saudi banking consolidation that followed, including the 2021 creation of Saudi National Bank from NCB and Samba. Integration ran about two years as planned; the bank rebranded as Saudi Awwal Bank and kept the SAB name. Through 2026 it has kept growing deposits and loans, reported resilient margins and fee income, and positioned itself as a financier of infrastructure, healthcare and housing programmes under Vision 2030. First-half 2026 net profit of SAR 4.42bn ($1.17bn) was up 4% on the same period of 2025.
