What does a fraudulent bank have to do with the fact that the FR is the ultimate backstop to loans (IOUs) created by a bank...a "power" you claim is the same as a non-bank created IOU or a an individual IOU? Further not sure how your example refutes my previous reply's accuracy, regardless, if a bank makes a bunch of fraudulent loans adding up to a Trillion dollars and it isn't discovered until those loans are cross-collateralized sufficiently to cause systemic risk, you can bet the FR will back those loans. Finally, given a bit of time a single Trillion dollar loan may not seem as large as it does now. :)
