Unless I am mistaken, the "twist" is not duration neutral; whereas
real bond investors tend to be duration sensitive. That is, selling $1
billion at the short end and buying $1 billion past the 10 year is
roughly equivalent to putting 7x the amount of real investor money into
the market. This is a point that has not been widely discussed — and
may explain why the bearish effects at the short end will be dwarfed by
the bullish effects at the long end.

Alston Mabry replies:

If 'duration' is the sensitivity of price to a change in 100 basis points of yield, and the Fed sells 2's and buys long bonds in equal amounts, and the Fed is effectively increasing their portfolio duration, does it follow necessarily that the Fed is putting around 7x more money into the bond market?

Doesn't it matter how the rest of the market participants decide to adjust to what the Fed is doing? What if long rates go up? I'm not saying they will, just wondering. Once QE2 was announced, the 5-year rate went up and stayed up until the end of QE2 was in sight. Now the Fed was actually printing money with QE2, and so the rise in the 5-year rate was coincident with a huge run-up in the stock and commodities markets. But it wasn't unreasonable to predict that QE2, aimed at 5-6 year maturity, would push the 5 year yield down.

For those who want to try and find quantitative relationships between Fed intervention and market moves…this operation schedule may be useful.

I still wonder how they sell off the short end and maintain ZIRP. Something will have to give, and I expect it to be the selling of short term.
