The relationship isn't perfect, but the correlation is very high. Based on this historical data, a Ten Year yield at 3.84% suggests a 30 year mortgage rate of around 5.75%.”

Although this is a limited amount of data - and the blue triangles are within the normal spread - this suggests the Fed's buying of MBS is reducing mortgage rates by about 35 bps.”
Pimco's Bill Gross Sees 2010 as Year of Reckoning
What does this say about the Federal Reserve's hopes to start pulling its added liquidity out of the markets, either by raising short-term rates or just getting out of buying bonds, which has been keeping long rates low?
I think the Fed's statements suggest that they really want to exit in some fashion from the buying program. The first step in that direction, logically, would be to stop buying, and our sense is that they're at least going to try that. But based on our forecasts for the second half of the year, they may have to reinitiate it, and that will be difficult to do once they stop because it then becomes a political hot potato.
All that said, I think they'll stop buying mortgage-agency securities, and the trillion-and-a-half-dollar check that's been written over the past nine to 12 months basically disappears. It's significant from the standpoint of interest rates and interest-rate spreads in certain sectors. And I would even go so far as to say it might be a mistake.Won't that put upward pressure on interest rates?I think it will. I mean, the mortgage market would be your first place to look, in terms of something that's overvalued that would become normalized. Nobody knows what the Fed's buying is worth — we think about half a percentage point on rates, but we don't know.

Fed's Kohn says impact from end of Fed MBS purchases matter of uncertainity Says:
- predicting Fed policy impact on rates especially hard
- especially important for banks to limit rate risk
- impact from ending MBS purchases likely to be modest- ‘volatilities’ unlikely to return to ‘quiescent state’- foreign capital may decline for US in coming years
Comments From Dan:
On the one hand we have comments from Calculated Risk blog (35 bps rise), Bill Gross of Pimco (50 bps), and the Fed’s Kohn indicating a relative modest increase in rates once the Fed’s MBS purchase program is completed. Based on a 35 bps to 50 bps rise in mortgage rates, this would point to a 30 Year Fixed mortgage rate of roughly 5.250% to 5.625%, based on recent mortgage rates (4.75% on a 30 Year Fixed Rate Mortgage).
However, if we applied the average spread from the time period preceding the MBS program, and experience an average spread of 2.09%, this would imply a slightly higher rate range, from 5.750% to 6.125%.
The risk, and in my opinion it is a significant risk, is that the comparison’s being made in the pre-Nov ’08 MBS period, had a significantly lower foreclosure/default rate. It would not be surprising to see the spread between 10 Yr Treasuries and 30 Yr Mortgage rates to initially spike to the higher end of the boundaries (the Nov 20, 2008 spread was 2.739%, which would imply a 30 yr mortgage rate in the 6.375% to 6.500% range, based on the 01/29/2010 close at 3.61% on the 10 Yr Treasury), in order to account for higher foreclosure/default risk.
In my opinion, I have not seen forecasts which adequately adjust for foreclosure/default risk in the projection of rates after the purchase program ends. My personal opinion is that it would not surprise me to see spreads widen beyond the upper bounds of the spread in the pre-Purchase sample period, i.e. above a 2.739% spread. It is conceivable that we could see 30 Year Fixed Mortgage Rates approaching 7% after the end of the Fed’s MBS Purchase Plan, even with a relatively flat Treasury yield.
