UBS has begun marketing its Sfr15bn (€9.4bn) rights issue weeks ahead of the annual general meeting where it will seek shareholder approval for the deal in a sign of the speed with which the Swiss bank wants to raise the money.

Bankers working on the UBS’s rights issue, as well as executives from the bank, have begun the international investor roadshow for the deal, meeting with shareholders across the world, said sources at the bank.
