(Reuters) - UBS was fined 30 million pounds ($48 million) by Britain's financial watchdog and put under extra scrutiny by its Swiss counterpart over failings that allowed a rogue trader to lose $2.3 billion.
Announcing the fine on Monday, the director of enforcement at Britain's Financial Services Authority (FSA) said the Swiss bank's risk control systems were "seriously defective."
Kweku Adoboli, a trader on UBS's Exchange Traded Funds desk in London, was jailed for seven years last week after admitting trading far in excess of authorized limits in the biggest fraud in British history.
"Failures of this type in firms of the size and standing of UBS not only damage the firms concerned but also wider confidence in the integrity of the markets and the financial system," the FSA's Tracey McDermott said.
In a separate announcement, the Swiss financial regulator Finma said it was examining whether UBS should increase capital to back its operational risks. A Finma spokesman declined to elaborate.
