Marc Faber on US TIPS bonds
"I have always been skeptical about buying inflation adjusted bonds (TIPS), simply because the yield on inflation adjusted fixed income securities is pegged to the CPI. Since the government will always understate the true rate of inflation the buyer of the TIPS will eternally be shorthanded. Moreover, I think that one day in future, the bond market will finally wake up to the fact that inflation has been understated and sell-off very badly. In fact, you would have to be the world’s greatest optimist (a la Abby Cohen or Larry Kudlow) to buy a US 30-years government bond in US dollars and with a yield of just 4.5% with the view to hold these bonds to maturity. You would have to assume that US inflation will never rise above 4.5% within the next 30 years and that the US dollar’s purchasing power will be maintained. Not a likely scenario, in my opinion (short term, however, bonds could rally somewhat more as the economy weakens)."
