Looking at the evidence here it doesnt seem that the fed can hike while using the 'exceptionaly low for extended period language'
1st - The Greenspan era 'In these circumstances, the Committee believes that policy accommodation can be maintained for a considerable period.' meant 1% were not going to be changed and the fed kept its word
2nd - The idea of putting a statement like that is to affect long-term interest rates expectations and bring down yields, you promise rates wont change, keep your word and the market prices that in, providing an interest rate stimulus. That would be inconsistent with putting a few hikes to 'adjust' things. Bernanke wrote
"One approach, similar to an action taken in the past couple of years by the Bank of Japan, would be for the Fed to commit to holding the overnight rate at zero for some specified period. Because long-term interest rates represent averages of current and expected future short-term rates, plus a term premium, a commitment to keep short-term rates at zero for some time--if it were credible--would induce a decline in longer-term rates."
3rd Up to this point the FOMC nor any ex-Fed member that I know of has mentioned some kind of financial stress that is generated by 13bps FF that doesnt exist at 50bps. Yes, savers get screwed but helping savers are not part of the Fed's mandate. Maybe there is money market fund issues with this?I havent heard anything about this, if there was issues I'm sure Hoenig would use as yet another reason to hike rates
