There is another ekathimerini article
that discusses the issue that the total amount is reduced. A quote from that article:
"As of September 1 any recipients of money forwarded from abroad will be able to withdraw 50 percent of the amount without any restrictions."
That could be a help to anybody transferring money in from abroad, i.e. probably most of us.
There also seems to be an easing of restrictions on opening accounts but it doesn't actually say anything about foreign nationals. For newcomers, who have been struggling to open a bank account, it might be worth asking after 1 September if they can now open one:
"Companies will also be able to open an account at a credit institution by creating a new customer ID regardless of whether they already have another account there. Farmers, who have not been allowed to open bank accounts since the controls started, will finally be allowed to (provided they do not have one already). Employees will be further able to open a new salary account at a different bank to the one at which they are already a client or if their new employer pays their salary at another lender."
