The clients of the US broker dealer MF Global’s British unit are to face further delays in having their positions confirmed and transferred after it emerged that a data flow problem within the failed company has slowed the process. Industry sources claim that a problem with London Metal Exchange (LME) data slowed the migration process.

The clients of the company have become increasingly frustrated in recent times as the company fail to provide a speedy resolution to the problem a week after they filed for bankruptcy.

Metals traders said on Monday that clearing house LCH.Clearnet, which is handling all of the data transfers, had promised to have the operation completed by Friday, however they have failed to do this and many people are still waiting.

A source claimed “A whole batch of data was lost last Monday. That’s one of the issues that has been holding everything up. The LME is working very hard on it, and the FOA (Futures and Options Association) is aware of it.”
