On April 17 Bitfinex announced that it is pausing USD wire deposits. In a new post from the exchange which currently accounts for over 12% of the overall Bitcoin exchange market share, they wrote that:
Beginning April 18, 2017, all incoming wires to Bitfinex will be blocked and refused by our Taiwan banks. This applies to all fiat currencies at the present time. Accordingly, we ask customers to avoid sending incoming wires to us until further notice, effective immediately.
The news came on the heels of Bitfinex stating that they were having problems with wire transfers with Wells Fargo, in which the exchange is suing the bank over the wire transfer issues.
As it appears, other major Bitcoin exchanges are also being impacted by USD banking issues.
OKCoin, which is based in China, also has posted a message to the exchange account deposit page, which reads:
Starting from today (April 18th, 2017), OKCoin would temporarily suspend USD deposit because of the issues with intermediary banks. Please do not make further deposit as your wires may be rejected by intermediary banks. We are now actively looking for alternatives to resume deposit as soon as possible. Your current account balance remains unaffected. We are sorry for any inconvenience caused.
A few days prior, another exchange BTC-e also stated in a tweet that they too were having problems with USD wire transfers, and announced they are changing banks.
Due to change banking account we don’t accept USD wire transfers till the end of month #btce

It’s unclear at this time if other Bitcoin exchanges are impacted as well, but they seem to all be operating without interruption.
