Global regulation of banking institutions has been a hot topic across the world since the fallout from 2008's crash. Regulation in the U.S and Europe has focused on solving the issue of "too big to fail" banking, whereas Chinese officials have made moves to try to cool a recent credit binge.
The European Central Bank (ECB) has embarked upon an asset quality review of the euro zone's banks, looking at stress testing each institution with a view of forming a banking union at a later date.

Elke Koenig, president of Germany's regulator BaFin, told CNBC that it was essential for the stress tests not to single out a particular country for any risk that it may hold. Shipping is seen as being an acute problem for German banks, with its heavy exposure to the sector, but Koenig said that the tests should be the same for every sovereign, or else there's a risk of there being multiple stress tests for each country.
"My argument is not to consider special scenarios for each country...shipping should be the same for everyone," she said. Koenig added that results of the tests should be available from early to mid-October, and would be in time for the ECB taking over responsibility of the banks.
