(RECAP: In a speech Tuesday, Federal Reserve Bank of New York President William Dudley laid out three key reasons why the Fed may keep its short-term interest rate — the federal funds rate — below historic averages for the long haul. That rate is important, because it impacts rates for mortgages and loans. Since 2008, the Fed has kept the federal funds rate near zero, but in better economic times, that rate averaged 4.25%. Going forward, Fed officials have said they expect to start raising rates sometime next year, but even so, Dudley expects it to remain “well below” the 4.25% level for the long run.)
