Also bank accounts were being frozen due to the new ruling that a non resident had to prove his status and declare and funds held in an overseas bank account.
(I think the above means non-residents declare the funds held in a Spanish account and only those resident in Spain have to declare funds held in an overseas bank account).
Banks must report the tax residence of account holders
They will have the obligation to do so between January 1 and May 31, 2017
The account will be blocked if the holder does not provide such information within 90 days
The above from an article in El Mundo. The full article is here and you can use Google translate for it
El Mundo Non-residence accounts
This worked the other way as we had to provide proof of Spanish residency to our UK bank and they wanted certified copies. They did say "a copy of the passport of the country you claim to be resident in" which is a bit silly. We sent copies of our Residency card and our NIE numbers and haven't heard anything since.
