Someone called their bank in Poland and asked about their limits. It is somewhere in this thread. Finding a good bank for a Bitcoin business is hard.
I guess I'll look but again I've never heard of a limit on transactions by a bank. Now their bank may be holding deposits for certain time and they can't send out withdrawals because of that. It's called a liquidity crunch but I just can't see a hold on incoming wires longer then 7-10 days.
I have a limit in my bank as well. I don't usually reach the limit.
Their limit is 120k EUR/day. I have no idea why the limit is so low. They are really sending that much, and the situation has in fact improved for SEPA. In May a SEPA withdrawal took 5 weeks, and I don't think anyone believe MtGox were in a liquidity crunch in May.
