This is an email from a FNMA account executive to clients on why the mortgage market is such a mess right now. It’s worth the read. <br /><br />The Capital Markets Sales Desk has fielded a large number of calls from customers simply asking, what’s going on? Why is the mortgage market trading lower every day? The following are reasons that could help explain why mortgages are struggling and why current market conditions are so volatile.<br /><br />The question is, why are mortgages widening or losing value vs other benchmarks like treasuries? Mortgages are widening for a number of reasons. First, there are no buyers. The dealer community is quite full and has no more balance sheet to hold mortgages. In addition, with the market so volatile, dealers don’t want to own mortgages at this time. Another reason why dealers do not have an appetite for risk is quarter end. Most dealers are experiencing a quarter end in March and have become even more conservative.<br /><br />Banks are not buying either. They are more concerned with retaining capital to cover potential losses in other sectors. Banks and other securities firms have written down an astonishing amount of losses since the subprime mortgage market fell apart last summer. According to Bloomberg, as of February 8th, write-downs by banks and securities firms around the world had reached $120 billion. Therefore, banks remain defensive and prefer to either retain capital or put it to work in other AAA rated sectors.<br /><br />Asia has been noticeably absent as well. Asian banks generally buy on strength and its obvious there hasn’t been any strength exhibited in the mortgage market recently. Also, Asia is generally more active at the end of the month so their absence this week is not a complete surprise.<br /><br />Money managers and hedge funds aren’t buying for the long term either. What they are doing is called momentum trading. They are buying at the wides (cheap) and selling at the tights (less cheap). Since they are buying and selling, they are not taking any production out of the market leaving the market to trade in a volatile fashion. The market is also trading very thin so exaggerated price movements occur when larger blocks are brought to market.<br /><br />Okay, we know that dealers, domestic banks, Asia, money managers and hedge funds are not buying. But, who is selling? Well, we know servicers have been selling. When the market sells off, the current coupon increases and servicers attempt to keep their hedges in the current coupon. Therefore, servicers need to sell lower coupons (longer duration coupons) and purchase higher coupons (shorter duration coupons). This is called moving up in coupon and is a form of shedding duration. However, in large market moves, servicers may need to sell without the corresponding purchase of the higher coupon. This is called outright selling. The outright selling and duration shedding from servicers has put extra downward pressure on mortgages.<br /><br />Originators are also selling. Although, with higher mortgage rates, originators aren’t selling as much as they were a month ago, the amount they are selling remains significant.<br /><br />Okay, servicers and originators were the two expected suspects, but are there any other sellers? Unfortunately there are, and this group of sellers is what brings fears to the market. Thornburg Mortgage, a mortgage REIT that specializes in Jumbo and Super Jumbo mortgages received a margin call from JP Morgan in late February. A margin call is a demand for cash on an under-collateralized loan. Thornburg was unable to meet a $28 million margin call and may be forced to liquidate its holdings. We are hearing talk of a $4.4 bln list of Non-Agency ARMs and pass-throughs out for the bid from Thornburg today.<br /><br />Another seller may be Carlyle Capital Corp, which is an investment bond fund located in Guernsey, UK. CCC missed four of seven margin calls totaling $37mln and another margin call notice is expected. According to Bloomberg, the fund raised $300mln in July and levered the money to purchase approximately $22bln in various forms of MBS. A portion of this $22bln is expected to be sold, and some market participants venture that a portion is being marketed today.<br /><br />Although this is only two of the many accounts that participate in the MBS markets, their forced sales could have major repercussions. For example, let’s say the bonds that are sold are sold at very low dollar prices. That may cause other market participants to mark their own portfolio down to current market levels. This may cause further write downs. The fear of further write-downs has banks on the defensive to a point where they want to preserve capital. If banks are preserving capital, then they are obviously not investing in MBS.<br /><br />The few investors who do have available capital are putting their money to work in more profitable sectors. Municipal Bonds and certain classes of CMBS are yielding more than Agency MBS and have a AAA rating. Despite the inherent “cheapness” in the mortgage market, there are still other safe investment options that are more preferable at the moment.<br /><br />In summation, we have more sellers than buyers. The selling bias puts pressure on mortgages, forcing mortgage prices lower and wider. The usual buyers of mortgages aren’t buying or are buying other investments at cheaper prices.<br /><br />Another trend we’ve noticed is a flight to quality within the mortgage market. Generally, when the market experiences a flight to quality, money is moving into US Treasuries. However, with treasury yields so low, market participants are buying the next best thing, GNMA MBS. GNMA MBS has the explicit guarantee of the US Government. Purchasing GNMAs allows an investor to enjoy the explicit guarantee while yielding considerably more than US Treasuries. In times like these, banks prefer to own GNMA MBS vs conventional MBS for a reason other than the explicit government guarantee. The reason is capital. Banks have to hold a certain amount of capital against their investments. However, they are required to hold significantly less capital against their GNMA holdings vs. their conventional MBS holdings. With the flight to quality within the mortgage market, and a preference by banks for GNMA MBS, it is no wonder why the GN/FN swap spreads have gapped out to astonishing levels. The current GN/FN 5.5% swap has gapped out from 18/32s from January 22nd, to its current level of 59/32s.<br /><br />Another thing to keep an eye on is ARM issuance. The yield curve has steepened in recent weeks (current difference in yield between the 2yr treasury and 10yr treasury is 208 bps). Generally, when the curve steepens, the difference in ARM rates and 30yr mortgage rates increases. Therefore, one may assume ARM issuance is likely to increase now that the curve has steepened. However, due to the lack of liquidity in the market, ARM MBS is trading extremely cheap. In other words, the correlation between a steep yield curve and lower ARM rates has decreased. Because lenders can’t sell their current ARM production in the secondary market at respectable levels, they can’t lower their offered rates. When liquidity improves, look for ARM issuance to increase.
