The CPI-U inflation rate was 2.7% for 2009, 1.5% for 2010, and 3.0% for 2011. So the 10-year TIPS I bought at the end of 2008 that paid CPI-U inflation rate plus 2.125% look pretty good. Even the new 10-year TIPS I bought in 2011 at virtually zero % plus inflation now look pretty good. And 100% downside protection if deflation since no accumulated inflation to chew through first like with bonds held in TIP. So why buy any more TIP at these prices?
