The promise of better returns on savings
In June 2006, the federal funds rate, the key interest rate that the Fed controls, stood at 5.25 percent. In September 2007, central bankers began lowering the federal funds rate and continued to do so until it fell to a range of 0 percent to 0.25 percent in December 2008. It remained there until the Fed raised it a notch, to a range of 0.25 percent to 0.5 percent in December 2015.
Rates on certificates of deposit (or CDs), money market accounts and savings also have stayed low.
The result has been devastating for retirees counting on safe, fixed returns, says Michael Rubin, founder of Total Candor, a financial planning education firm based in Portsmouth, New Hampshire.
"They're earning a lot less on their savings than any other time in recent history," says Rubin, author of "Beyond Paycheck to Paycheck."
However, even getting a sad-sack 1 percent return has been preferable for retirees, says Alan Moore, a financial planner and co-founder of XY Planning Network in Bozeman, Montana.
"When the stock market takes a dive, (retirees) don't want to be in the position of having to sell stocks to fund their lifestyle,” he says.
