I don't think so, they will be loosing allot of money and many customers start switching to other banks, the statement doesn't forbid such transactions, it was clear that individuals has to take risks when dealing with Bitcoin which is not new. we always took risks on our own bitcoin investment.
till now Bitcoin was used as commodity more than a virtual currency and till now we didn't see any bank using Bitcoin for transactions or anything related, so I really do not understand where the panic come from.
Bitcoin wasn't in the black nor the white area in china it was in the gray area, now this issue has been addressed and bitcoin is in the white area, people can buy it sell it trade it and use it as a commodity.
I see this new really positive, though the ban for organizations from using bitcoin came a bit surprising, yet understandable, do not forgot China has a record in banning websites,firms and related technology businesses, so the statement is really positive, I was afraid that they will ban Bitcoin as the whole concept.
give it some time and it will settle, people still don't understand what is going on, or rather shocked.
