That can&#x27;t happen without crashing the entire system.  Interest rates are effectively zero because everyone (governments, businesses, citizens...) is carrying all the debt they can handle.  If they try to raise the interest rates the entire world will go bankrupt.  As usual, Bloomberg points the finger at bank regulation.  The banks should never have survived the 2008 crash, but $2.5Trillion buys you a lot of time.  Remember, all that QE went to pay down financial sector losses from the crash.  It didn&#x27;t do anything to ease the debt logjam.
