Negative interest rates really aren't scary, they're just unusual in an era (since early 1980's) where inflation targeting (which is closely coupled with interest rates) of ~2% is the norm for the world's most important central banks. Here's a good overview from Bernanke (pre chairman of Fed years). [1]<p>In the short run, nothing will change from a day-to-day consumer perspective. Your 0.05% interest-rate saving account might drop to a 0.01% interest-rate account. If you have <i>a lot</i> (tens of millions) of money that you'd like to put in a liquid savings account, you might be charged a slightly negative interest rate. Some banks are already doing this with institutional investors, but I doubt it will trickle down into commercial consumer banking. [2]<p>Kocherlakota, an ex-fed economist whose views I respect, called for negative rates yesterday: "The FOMC needs to go negative - and that's a gigantic <i>fiscal</i> policy failure." I have to agree.<p>As he points out, low real interest rates present "an incredible opportunity" for US gov to make huge, necessary infrastructure investments.

So they continue to lose control over once-powerful monetary policy tools. This is only scary if you put a lot of stock into a central bank's altruism, benevolence, and ability to effectively guide an extremely complex and intertwined economic/financial system.<p>[1] <a href="http://www.federalreserve.gov/Boarddocs/speeches/2003/20030325/default.htm" rel="nofollow">http://www.federalreserve.gov/Boarddocs/speeches/2003/200303...</a><p>[2] <a href="http://www.bloomberg.com/news/articles/2015-02-26/julius-baer-charges-institutional-clients-for-snb-negative-rate" rel="nofollow">http://www.bloomberg.com/news/articles/2015-02-26/julius-bae...</a>
