Fears of counterfeit $50 and $100 bills have disrupted foreign-exchange trade at Istanbul’s Grand Bazaar, the nation’s largest currency trading gray market.

According to the state-run Anadolu Agency, some bureaus at the bazaar, a hub for currency trading, stopped purchasing the bills, saying the counting machines they use can’t identify the fake notes.

“The number of counterfeit dollars isn’t clear,” Anadolu cited Resat Yilmaz, a tradesman at the Bazaar, as saying. “These bills have to be collected, which can take two weeks.” Money-counting machines also have to be updated, he added.

A representative for currency traders said the disruption has no basis and “there’s no fake currency” in circulation. He blamed banks for what he said was a “clogging” of trading.

“Banks should accept old dollar bills. Currently, no bank is doing that,” Mehti Seren, head of the Association of All Authorized Institutions and Foreign Exchange Offices, said in a press conference. “Clients are then returning the dollars to us. That’s what’s clogging the system.”

The central bank said it’s sent warnings and expert opinions about the fake bills to banking associations.

“The necessary guidance on precautions to be taken regarding the technological infrastructure has been made,” the bank said in a statement. Bill counters, bill checkers and teller machines are being controlled and updated, the Turkish Banks Association said in a separate statement.

The prosecutor’s office in Istanbul launched an investigation, Anadolu said. The counterfeit bills entered Turkey from abroad, Haberturk reported, citing sources it didn’t identify.
