Bank Asya’s problems – withdrawal of deposits by individual and corporate investors, the wiping out of profits, the dramatic fall in share price – have apparently nothing to do with the way the bank is run. They have everything to do with a politically-motivated vendetta against the bank by Turkey’s president, Recep Tayyip Erdogan. A year on, Bank Asya continues to operate under the leadership of a former senior member of Turkey’s respected banking supervisor, the BDDK, which has tried to remain impartial to Erdogan’s machinations. But the battle for Bank Asya remains a cloud over the Turkish banking sector. Banks that do business in Turkey should tread with caution.
