In a Crisis, Fed Says Big Banks Will Get Bigger

Neither the banks nor the Fed are entirely transparent about the models they use to get to these results, so you can't really say who's right and who's wrong, though there is an obvious and important sense in which the Fed is necessarily right and each bank is wrong in proportion to how far it differs from the Fed, which is not final because it is infallible but rather infallible because it is final. If the Fed tells you you can't buy back shares, the arguable greater accuracy of your model will be little consolation.
