The bank has suffered major losses since last year following massive deposit withdrawals linked to a bitter feud between Erdogan and his former ally, US-exiled Fethullah Gulen.
The state-run Savings Deposit Insurance Fund (TMSF) seized 63 per cent of Bank Asya shortly after the banking watchdog (BDDK) ruled in favour of its seizure, state-run Anatolia news agency said yesterday.
The BDDK said in a statement on its website that it seized the bank "because the institution has not presented a partnership structure that is transparent and open enough to allow for effective regulation..."
The bank, founded by followers of Gulen in 1996, has come under pressure from regulatory restrictions, withdrawals by government-run companies and attacks from pro-government newspapers.

The pressure on Bank Asya resulted in a crash of its share price and a massive downscaling of its operation.
The bank said in November that it lost 301 million liras (USD 133 million) in the third quarter -- its first unprofitable quarter since it went public in 2006.
The seizure of the bank is the latest crackdown against Gulen's powerful movement known as "Hizmet", which brings together interests ranging from finance to schools to media.
