Yesterday the 10 year TIPS closed at an all time low of -0.33%. The flight to safety due to the Greek crisis pushes TIPS down because 10 year exceptions of inflation are not really being affected by Greece. ( TIPS + inflation expectation = Nominal treasury yield ). Fixed income investors are going to have to tolerate an “extended period” of low returns. If you want to see this data in a nice convenient form look under the fixed income > historic yields tab and select TIPS.
