The Monetary Authority of Singapore has lifted the ban on the sale of structured notes on six brokerage firms.

With immediate effect, CIMB Securities, Kim Eng Securities, OCBC Securities, Phillip Securities, DMG & Partners Securities and UOB Kay Hian are allowed to again sell structured notes. The regulator said in a statement that the six firms had already corrected all identified flaws related to the issue and that the external parties assigned to monitor them had expressed satisfaction over the companies' compliance. The six have also pledged to continue implementing enhancements to their reporting and delivery systems.

The MAS had issued the prohibition at the height of the global crisis with the view to reining in potential problems identified after the collapse of Lehman Brothers.

As part of the MAS' action, companies were given six-month to one-year bans. The regulator lifted a similar ban on Maybank, the Royal Bank of Scotland, and DBS Bank early this year.
