MBS: Shorter Empirical Durations Under QE<br />
• QE3 is likely to bring in lower empirical<br />
durations akin to QE1, due to stability in rates<br />
and mortgage prices.<br />
• The 15bp to 30bp state-based upfront g-fee<br />
amounts to a small 3bp to 6bp rate increase,<br />
based on the IO multiple of 5 used by the FHFA.<br />
With the Fed bringing an element of stability to rates<br />
and particularly mortgage prices, empirical durations<br />
have begun to decline. Chart 1 shows the ratio of<br />
empirical-to-trader hedge ratios for 3.5s and 5s; we<br />
chose just those two coupons as representatives to<br />
provide a clearer picture of the contrast between lower<br />
and higher coupons. While the ratios for all coupons<br />
are declining, the declines seem to be of a greater<br />
magnitude in higher coupons. Plus, the ratios are<br />
greater than one in 4.0s and lower coupons, but lower<br />
in 4.5s and higher coupons.<br />
A similar trend was observed during QE1, when<br />
empirical hedge were ratios shorter than trading ratios,<br />
particularly for higher coupons (Chart 2). We show 4.5s<br />
and 6s as representatives since the current coupon<br />
was much higher during QE1 than at present. Lower<br />
empirical durations would improve the hedge carry of<br />
MBS. The decline post-QE3 announcement has also<br />
helped to improve hedge adjusted carry across the<br />
coupon stack (Chart 3).<br />
We continue to expect MBS to outperform<br />
Treasuries, despite the richening, given steep<br />
demand from the Fed against a negative net supply.<br />
Clearly, carry is already attractive and should<br />
improve further with lower durations and volatility.<br />
However, as we discuss in an accompanying article,<br />
”QE3 Impacts on US Spread Products”, riskier asset<br />
classes, such as corporates, may perform even<br />
better than MBS.<br />
State-Based G-fee<br />
FHFA announced that it would potentially implement<br />
an additional state-level g-fee (guarantee fee), starting<br />
in 2013, for five states: Connecticut (20bp), Florida<br />
(20bp), Illinois (15bp), New Jersey (20bp) and New<br />
York (30bp). This g-fee proposal is under comment<br />
period for 60 days. Lenders may pass the upfront fee<br />
as an adjustment to the interest rate on the borrower’s<br />
loan. The FHFA used the suitable IO multiple of 5 in<br />
their example to make the adjustment to the annual<br />
rate from upfront fee. This amounts to a small 3bp to<br />
6bp rate increase, depending on the state.<br />

The g-fee estimation is based on three factors. The<br />
first is the expected number of days that it takes an<br />
Enterprise to foreclose and obtain a marketable title to<br />
the collateral backing a mortgage in a particular state.<br />
The second is the average per-day carrying cost that<br />
the Enterprises incur in that state. The third is the<br />
expected, national average default rate on singlefamily<br />
mortgages acquired by the Enterprises. To<br />
estimate the magnitude of the state-level differences<br />
in the average total carrying cost, the estimation<br />
assumes that loans originated in each state will default<br />
at the national average default rate.<br />
