HKMA ring-fenced assets before Lehman collapse

At the time, the financial services watchdog moved to ring-fence the assets held by those institutions in Hong Kong where possible. It also expressed concerns to local financial institutions about the risks inherent in certain structured credit instruments, such as collateralised debt obligations (CDOs).

The revelations were made on April 14 by HKMA's chief executive Joseph Yam, who appeared before the Hong Kong legislature's subcommittee established to study issues arising from Lehman Brothers-related minibonds and structured financial products. This was the first time Yam had received a summons from the subcommittee, which has held its fifth hearing since February after many retail investors in Hong Kong lost money on structured credit instruments called minibonds. Previously, Chan Ka-keung, secretary for financial services and the treasury, had appeared before the subcommittee.

Yam said that, in a bid to maintain stability of the city's banking system and protect the interests of Hong Kong investors, the HKMA had identified 19 international banks and put them on an "intensive monitoring" list. The HKMA then ring-fenced the assets of their branches in Hong Kong to ensure they could not be repatriated by their parents.

"We have had concerns over the [knock-on effect that could be spread to Hong Kong] on a systematic scale... because in the end the victims are the investors and depositors [within our own jurisdiction]," he told law-makers in the subcommittee.

Yam said the HKMA has also increased the magnitude of coefficients it uses for stress testing and has used such tests to study the worst-case scenarios facing the Hong Kong banking system. As a result, Yam said the HKMA had devised "various back-up plans" aimed at providing liquidity funding the Hong Kong branches of foreign banks.

While Yam failed to provide further details, he said in a column on the HKMA's website last week entitled 'Supervising international banks - co-operation among banking supervisors is important' that ring-fencing generally falls into three categories.

The first has the aim of retaining adequate capital to support the normal activity of a bank in the host jurisdiction, for example, by requiring the subsidiary bank to operate with a more conservative capital adequacy ratio. The second has the objective of upgrading the quality of liquidity available to the subsidiary bank in the host jurisdiction. For example, the credit risk associated with placing liquid funds with other financial institutions - including the parent bank - would need to be closely scrutinised.

The last category involves preventing deterioration in the asset quality of a subsidiary bank that might be brought about by booking doubtful assets originating overseas in the bank's balance sheet.

During the subcommittee meeting, legislators questioned Yam about whether or not he was aware of the riskiness of the minibonds, or credit-linked notes tied to a basket of synthetic CDOs, marketed by Lehman Brothers. Yam said the HKMA began asking banks to pay special attention to risk assessment and client suitability related to CDOs due to their high-risk nature back in 2006.

But Yam said the HKMA could not issue risk alerts on individual products or financial institutions as the regulator does not have a front-line supervisory role and ethical issues are raised if the regulator is seen to make judgements regarding specific financial products.

The chief financial officer at one local bank said he was not aware of such monitoring activity conducted by the HKMA.
