Three private banks operating in Turkish lire have fallen foul - albeit temporarily - of the BDDK, Turkey's bank regulator. It imposed a trading ban on them on Friday for 'failing to meet their lire liabilities' but has now lifted the ban.

At the same time that the BDDK imposed its ban,  the state-owned broadcaster Anadolu accused financial institutions in London of "manipulative attacks" on the lira. The news agency Haberler says that the three banks were engaged in such attacks in order to depreciate the lire.

The regulatory ban, according to Reuters, was on transactions in the lire and affected movements of money between affiliates in each banking group. Reuters believes that this was an attempt to shore up the Turkish lire - which has dropped in value in recent months.

Haberler says that the BDDK lifted its sanction because the three financial institutions had "fulfilled their obligations in a reasonable time," although some kind of investigation is still in progress.
