SocGen's 2029 cost-income target leans more on 3% revenue growth than on its €500M AI saving

A 2029 target below €16.3bn that sits roughly 2 percent under the estimated 2026 figure implies a 2026 base of about €16.6bn ^[1][3][15]. At a cost-to-income ratio of roughly 60 percent, that base implies income of about €27.7bn ^[7][16]. Compound that at the 3 percent growth rate the bank is guiding to and 2029 income is about €30.3bn ^[8][17]. Costs of €16.3bn against income of €30.3bn is a ratio of 53.8 percent ^[18].

Hold income flat and the cost programme on its own takes the ratio to 58.8 percent ^[19]. Of the six points between roughly 60 today and the 53.8 the targets imply, about one comes from spending less and five come from earning more ^[20]. If revenue compounds at 1 percent instead of 3, income is about €28.5bn and the ratio lands at 57.1 percent, above target, with every euro of the cost plan delivered ^[21].

The AI line item is the largest single piece of the gross number and considerably larger than what reaches the bottom line. Roughly €500m of IT savings is about 26 percent of the €1.9bn gross ^[25] and about 1.7 times the €300m net reduction the bank expects after reinvestment and other adjustments ^[22]. Cryptobriefing reads the gap between the two as roughly €1.6bn of reinvestment and transition costs ^[6]. On those figures 84 percent of the gross savings is spent back into the business ^[23].

SocGen's record on AI procurement is a year old. The bank built its own tool, SoGPT, then decommissioned it earlier in 2026 in favour of Microsoft's Copilot after performance gaps appeared ^[11], and has since signed a strategic partnership with Anthropic aimed at accelerating AI integration across its operations, with a focus on productivity and client services ^[12]. A €500m savings figure dated 2029 therefore rests on a supplier mix that has already been reset once. Read IT intensity as IT spend against income and the 12 percent target ^[13] is about €3.6bn on €30.3bn of 2029 income ^[24], so the AI saving is roughly a seventh of that line.

There is a reading in which the €500m understates the case. If Copilot and Claude raise output per employee, the gain arrives as income, and the 3 percent revenue assumption is where it would show up ^[8][12]. Against that, the 1,800 French roles are coming out primarily through natural attrition ^[10]. Attrition sets the pace of the personnel saving, and a bank deploying new tools while waiting for leavers is carrying both costs at once.

Krupa has been running this turnaround since 2023 on cost discipline, profitability and simplification ^[14]. The 2029 plan gives shareholders two checkable numbers: a cost-to-income ratio below 55 percent and return on tangible equity of 13 to 14 percent, with an ambition above 15 percent after that ^[7][9].
