For the curious, here is the best article I have seen on the newly created global banking requirements.
After a lot of complaining from bankers, the regs are a little lighter than they might have been, though raising reserve and capital requirements will still undoubtedly cut into profits. Individual countries, including the US, will still need to codify the regulations into their own legal systems, which could take some time. However, post-financial crisis, it should not be that difficult for most legislative bodies in the developed countries to get, at the very least, close approximations passed.
UPDATE: Some further info on the new regs, including video analysis. It seems as if the markets appreciate that the rules don't go overboard and the long timelines banks have been given to implement changes.
