This is the third instance when outsourcing of key oversight jobs by global banks (British giants HSBC and Standard Chartered being the other two) to India has come under the regulatory scanner abroad for ineffective controls against suspicious financial transactions.

UK's Financial Services Authority (FSA) fined UBS 29.7 million British pounds (about Rs 265 crore) for failing to prevent large-scale unauthorised trading in this case, while Swiss regulator FINMA (Financial Market Supervisory Authority) also said it has found serious risk management deficiencies and major control failures at the bank.

In its probe report, FINMA said that UBS' back office operations team was responsible for ensuring timely confirmation of deferred-settlement trades, identified through "a specific report maintained by an outsourcing provider based in India (the 'T+14 report')".

The probe found that the bank's online trade supervision system SCP (Supervisory Control Portal) and the 'T+14' report "were key controls for the detection of suspicious trading activity, but both proved to be ineffective.

"The failures of these controls serve to illustrate poor organisation and risk management within UBS," FINMA said.

FSA and FINMA jointly initiated a probe in September 2011 after it came to the light that a London-based trader of Swiss banking major had caused substantial losses totalling USD 2.3 billion (about Rs 13,000 crore) due to unauthorised trading on the bank's Exchange Traded Fund (ETF) desk.

Listing out the activities that led to the loss, FINMA said that "fictitious ETF trades with deferred settlement dates" was one of the main concealment mechanisms used by the rogue trader.

"These trades, which were cancelled before reaching settlement, generated fictitious risk exposure and P&L (profit and loss for the ETF desk). Deferred settlement trades should have been identified on the T+14 report (maintained by India based outsourcing provider).

"However, this report was non-operational between May and November 2009, and from November 2010 to September 2011 (shortly before discovery of the loss)," the regulator said.

The FINMA said that "the purpose of the 'T+14' report was to identify deferred settlement trades, as these posed a greater risk to the bank than trades settling within the usual T+3 cycle.

"The importance of this report was not understood. The report failed twice, for extended periods of time, and the second failure of the report went unnoticed by UBS for approximately 10 months," it added.

"Consequently, there was no working control in place to identify the large, deferred settlement trades booked by the ETF Desk," the regulator said.

Outsourcing of financial market oversight jobs by global banks to India has come under the scanner for the third time in last few months.

Earlier, a probe by the US Senate's Permanent Committee on Investigations had found major lapses in the work of HSBC's India staff, while another UK-based banking giant Standard Chartered's outsourcing of key banking jobs to Indian shores also came under the US regulatory scanner in August this year.

A probe by the New York State's key banking regulator, the Department of Financial Services (DFS), found deficient money laundering controls in outsourcing of work by StanChart to India, thus exposing the US financial system to terror financing and other risks.

The DFS had accused StanChart of hiding secret transactions involving USD 250 billion with Iran – leaving the US financial system vulnerable to terrorists, weapons dealers, drug kingpins and corrupt regimes. However, StanChart later settled the case after payment of certain charges.

In the case of UBS also, FSA said that it lowered the fine to 29.7 million pounds (about Rs 270 crore) from 42.4 million pounds (about Rs 380 crore) as the Swiss bank agreed for an early settlement.
