Some analysts concede that the traditional Fed policies have indeed left the dollar vulnerable to serious devaluation, but they think the central bank wizards can save the day by acquiring new “tools.” For example, San Francisco Fed president Janet Yellen has been arguing that the Fed should be able to issue its own debt, to give the Fed more flexibility. The idea is that when the time comes for the Fed to sop up the excess reserves it has pumped into the banking system, it would be devastating to the incipient economic recovery if the Fed has to dump a bunch of mortgage-backed securities, or Treasury bonds, back onto the market. This would ruin the banks with MBS on their balance sheets, and/or it would push up interest rates for the government. Thus, the Fed would have painted itself into a corner, and it would have to choose between massive CPI hikes or a renewed recession. To avoid that nasty tradeoff, Yellen argues that if the Fed could sell its own debt, then it could drain reserves out of the banking system without unloading its own balance sheet.
For a different idea, economists Woodward and Hall think the Fed just needs the ability to charge banks for holding reserves. The Fed already (recently) obtained the right to pay interest on reserves, and so Woodward and Hall think the Fed should also have the ability to do the opposite, i.e. to be able to pay a negative interest rate on reserves that banks hold on deposit with the Fed.
