Quote from mtzianos:
What people need to understand, when trying to explain bond yields, is that today's markets are dominated by players who DO NOT have "profit maximizing" objective. Normal investors want to maximize their profits and get compensated for taking risk.
On the other hand in case of Foreign Central Banks, they don't care if the bonds make any money! Bank of Japan has over 100bn losses from their practice of buying US bonds last 3yr. They buy them to support a mercantilistic policy or to subsidize employment etc
Also dominant are players of the "carry trade" who are "arb'ing" between various instruments, simply because the US Fed has been so predictable for so many years that they can be sure they'll have time to abandon the ship on time. At least they seem to think so and afterall, it's other people's money they're playing with.
To folks who insist in bringing up the subject of "low inflation", citing the manipulated CPI numbers, I can only suggest that they ask themselves if the 4% offered last few years, would help them maintain their purchasing power, or heaven-forbid, increase it a bit. i.e. view things from the perspective of an INVESTOR / retired person etc.
It helps to just look what value investors, like Buffet, do. He's sitting on cash and no single long-term bond. Even the largest bond fund managers, PIMCO, won't touch the US long bonds.
