The US’s biggest bank is set to offload 10-15 floors of the 44 at its 111,480m2 (1.2m sq ft) Canary Wharf tower.
Citigroup’s decision is a sign that investment banks are cutting back their real estate needs as revenues shrink.
Canary Wharf’s head of leasing, Mike Hussey, said: “We’ve always said that there was a strong possibility that Citigroup would sublet because it had acquired more space than it needed.”
