The increase of an organized secondary market for conventional mortgage loans during the 1970 and early 1980 has expanded up many new opportunites for savings institution managers. It has given the mortgage instrument a frequently higher degree of liquidity, which has provided earnestly greater flexibility in managing the mortgage portfolio. More lately selling loans in an active secondary market has provided institutions a way to continue to be mortgage lender without incurring the risk of adding long-term fixed-rate loans to their portfolios.

The unravelling of this market has also created a fertile field for academic research. Researchers have been interested in the way in which the secondary market has affected mortgage rates and loan-terms--both their absolute on a level and the differences among regions. This article discusses the vegetation of the secondary market since 1970 and then reviews more [i]or[/i] less recent research dealing with these questions. development of the Market

a perspective on the growth of the secondary mortgage market can be obtained from Charts 1 to 3 Chart 1 indicates the tremendous growth in the amount of mortgage lake securities outstanding from year-end 1970 to year-end 1982 These pond s are represented by Government National Mortgage Association (GNMA) passthrough certificates and Federal household Loan Mortgage Corporation (FHLMC) participation certificates, the pair of which have existed since the early 1970 as well as the newer Federal National Mortgage Association (FNMA) passthrough certificates. After rising to $144 billion by dint of the end of 1972, the outstanding amount of mortgage pond securities more than tripled to $568 billion by means of the end of 1977. At the conclusion of 1972, mortgage pools delineateed 4.0 percent of total residential mortgage trespass outstanding. (See Chart 2) This increased to 89 percent at the period of 1977 and 16.1 percent at the expiration of 1982.

on the same level more impressive is the amplitude to which the expansion in mortgage pools has contributed to the germination in outstanding mortgage debt. Chart 3 illustrates this from presenting a comparison of the change in the amount of mortgage pond securities with the change in total residential mortgage liability For example, in 1977 mortgage lochs increased from $40.7 billion to $568 billion (see Chart 1) while total shortcoming increased from $544 million to $635 million. The $161 billion increase in mortgage pond s thus represented 17.7 percent of the debit increase. In 1982, mortgage sin increased by only $46.9 billion, reflecting let downed conditions in the housing market. through coincidence, mortgage pools also increased according to about $47 billion in 1982 with equal reason that, in effect, the secondary market accounted for all of the development in mortgage debt in 1982

Talk of the integration of the mortgage market into the general capital markets, which had been prevalent in financial circles since at least the mid-1970s, became a reality at the early 1980s. In fact, the above figures understate the size of the secondary market, since many secondary market transactions involve the sale of individual mortgages and do not come in the creation of market puddles On the other hand, in 1982 the figures are somewhat distorted because a large portion of the extension in mortgage pools reflects the succes of the Federal family Loan Mortgage Corporation's "guarantor" program, in which lender swap older low-rate mortgages for passthrough securities. In this situation, a mortgage pond is created without a corresponding amount of just discovered lending activity. In previous years, plashs were created primarily to capital new lending activity.

While there are any measurement problems, the growth of the secondary market--and its support of the primary market--is impressive, as these statistics make clear. For an increasing number of associations, the secondary market has become the mortgage market. It is often met with for example, to hear of institutions which betray almost all of the fixed-rate loans they make to single of the mortgage agencies or to private sources. Impact onward Mortgage Yields and Spreads

With this background, we can review the findings of any recent studies on such issues as the event of the development of the secondary market onward mortgage yields and on interregional differences in mortgage rates. In theory, the integration of the mortgage market into the Nation's overall capital market s should have two effects. First, through creating greater competition in the mortgage market and increasing the afford of mortgage funds, it should bring mortgage rates more in line with other interest rates. Secondly it should convert into interregional differences in mortgage rates.

With regard to the first of these weights a 1980 study by Hendershott and Villani argues that this is exactly what had happened by dint of the late 1970s. According to the authors, the unravelling of the secondary mortgage market "has improved interregional grows of mortgage funds and has given mortgage borrowers a greater access to capital markets generally. The principal proceed has been a decline in the mortgage rate relative to other market rates..." [2 p 50] This decline in the spread between mortgage rates and other interest rates to which Hendershott and Villani called attention is illustrated in Table 1 For example, from 1963 to 1965 (before the first period of disintermediation in 1966 and before the growth of an organized secondary market for conventional loans), the spread between conventional mortgage rates forward loans closed and rates upon 10-year US government bonds ranged from 153 to 193 basis points. from 1978, the spread had declined to 113 basis points.
