High-risk Mortgage Loans and Lending Practices

Lenders began to offer more and more loans to higher-risk borrowers, including illegal immigrants. Subprime mortgages amounted to $35 billion (5% of total originations) in 1994, 9% in 1996, $160 billion (13%) in 1999, and $600 billion (20%) in 2006. A study by the Federal Reserve found that the average difference between subprime and prime mortgage interest rates (the "subprime markup") declined from 280 basis points in 2001, to 130 basis points in 2007. In other words, the risk premium required by lenders to offer a subprime loan declined. This occurred even though the credit ratings of subprime borrowers, and the characteristics of subprime loans, both declined during the 2001–2006 period, which should have had the opposite effect. The combination of declining risk premia and credit standards is common to classic boom and bust credit cycles.

In addition to considering higher-risk borrowers, lenders have offered increasingly risky loan options and borrowing incentives. In 2005, the median down payment for first-time home buyers was 2%, with 43% of those buyers making no down payment whatsoever.

One high-risk option was the "No Income, No Job and no Assets" loans, sometimes referred to as Ninja loans. Another example is the interest-only adjustable-rate mortgage (ARM), which allows the homeowner to pay just the interest (not principal) during an initial period. Still another is a "payment option" loan, in which the homeowner can pay a variable amount, but any interest not paid is added to the principal. An estimated one-third of ARMs originated between 2004 and 2006 had "teaser" rates below 4%, which then increased significantly after some initial period, as much as doubling the monthly payment.

Mortgage underwriting practices have also been criticized, including automated loan approvals that critics argued were not subjected to appropriate review and documentation. In 2007, 40% of all subprime loans resulted from automated underwriting. The chairman of the Mortgage Bankers Association claimed that mortgage brokers, while profiting from the home loan boom, did not do enough to examine whether borrowers could repay. Outright fraud has also increased.

Speculation in Residential Real Estate

Speculation in residential real estate has been a contributing factor. During 2006, 22% of homes purchased (1.65 million units) were for investment purposes, with an additional 14% (1.07 million units) purchased as vacation homes. During 2005, these figures were 28% and 12%, respectively. In other words, a record level of nearly 40% of homes purchases were not intended as primary residences. David Lereah, NAR's chief economist at the time, stated that the 2006 decline in investment buying was expected: "Speculators left the market in 2006, which caused investment sales to fall much faster than the primary market."

While homes had not traditionally been treated as investments, this behavior changed during the housing boom. For example, one company estimated that as many as 85% of condominium properties purchased in Miami were for investment purposes. Media widely reported condominiums being purchased while under construction, then being "flipped" (sold) for a profit without the seller ever having lived in them. Some mortgage companies identified risks inherent in this activity as early as 2005, after identifying investors assuming highly leveraged positions in multiple properties.

Economist Robert Shiller argues that speculative bubbles are fueled by "contagious optimism, seemingly impervious to facts, that often takes hold when prices are rising. Bubbles are primarily social phenomena; until we understand and address the psychology that fuels them, they're going to keep forming." Keynesian economist Hyman Minsky described three types of speculative borrowing that contribute to rising debt and an eventual collapse of asset values:

* The "hedge borrower," who expects to make debt payments from cash flows from other investments;
* The "speculative borrower," who borrows believing that he can service the interest on his loan, but who must continually roll over the principal into new investments;
* The "Ponzi borrower," who relies on the appreciation of the value of his assets to refinance or pay off his debt, while being unable to repay the original loan.

Speculative borrowing has been cited as a contributing factor to the subprime mortgage crisis.

Boom and Bust in the Housing Market

A culture of consumerism is a factor "in an economy based on immediate gratification." Starting in 2005, American households have spent more than 99.5% of their disposable personal income on consumption or interest payments. If imputations mostly pertaining to owner-occupied housing are removed from these calculations, American households have spent more than their disposable personal income in every year starting in 1999.

Low interest rates and large inflows of foreign funds created easy credit conditions for a number of years prior to the crisis. The USA home ownership rate increased from 64% in 1994 (about where it had been since 1980) to an all-time high of 69.2% in 2004. Subprime lending was a major contributor to this increase in home ownership rates and in the overall demand for housing.

This rise in demand fueled rising house prices and consumer spending. Between 1997 and 2006, the price of the typical American house increased by 124%. During the two decades ending in 2001, the national median home price ranged from 2.9 to 3.1 times median household income. This ratio rose to 4.0 in 2004, and 4.6 in 2006. This housing bubble resulted in quite a few homeowners refinancing their homes at lower interest rates, or financing consumer spending by taking out second mortgages secured by the price appreciation. USA household debt as a percentage of annual disposable personal income was 142% at the end of 2007, versus 101% in 1999.

Household debt grew from $705 billion at yearend 1974, 60% of disposable personal income, to $7.4 trillion at yearend 2000, and finally to $14.5 trillion in midyear 2008, 134% of disposable personal income. During 2008, the typical USA household owned 13 credit cards, with 40% of households carrying a balance, up from 6% in 1970.

This credit and house price explosion led to a building boom and a surplus of unsold homes. Easy credit, and a belief that house prices would continue to appreciate, encouraged many subprime borrowers to obtain adjustable-rate mortgages. These mortgages enticed borrowers with a below market interest rate for some predetermined period, followed by market interest rates for the remainder of the mortgage's term. Borrowers who could not make the higher payments once the initial grace period ended would try to refinance their mortgages. Refinancing became more difficult, once house prices began to decline in many parts of the USA. Borrowers who found themselves unable to escape higher monthly payments by refinancing began to default.

By September 2008, average U.S. housing prices had declined by over 20% from their mid-2006 peak. This major and unexpected decline in house prices means that many borrowers have zero or negative equity in their homes, meaning their homes were worth less than their mortgages. As of March 2008, an estimated 8.8 million borrowers — 10.8% of all homeowners — had negative equity in their homes, a number that is believed to have risen to 12 million by November 2008. Borrowers in this situation have an incentive to "walk away" from their mortgages and abandon their homes, even though doing so will damage their credit rating for a number of years. The reason is that unlike what is the case in most other countries, American residential mortgages are non-recourse loans; once the creditor has regained the property purchased with a mortgage in default, he has no further claim against the defaulting borrower's income or assets. As more borrowers stop paying their mortgage payments, foreclosures and the supply of homes for sale increase. This places downward pressure on housing prices, which further lowers homeowners' equity. The decline in mortgage payments also reduces the value of mortgage-backed securities, which erodes the net worth and financial health of banks. This vicious cycle is at the heart of the crisis.

Increasing foreclosure rates increases the inventory of houses offered for sale. The number of new homes sold in 2007 was 26.4% less than in the preceding year. By January 2008, the inventory of unsold new homes was 9.8 times the December 2007 sales volume, the highest value of this ratio since 1981. Furthermore, nearly four million existing homes were for sale, of which almost 2.9 million were vacant. This overhang of unsold homes lowered house prices. As prices declined, more homeowners were at risk of default or foreclosure. House prices are expected to continue declining until this inventory of unsold homes (an instance of excess supply) declines to normal levels.

Subprime Mortgage Crisis: Credit Risk

Credit risk arises because a borrower has the option of defaulting on the loan he owes. Traditionally, lenders (who were primarily thrifts) bore the credit risk on the mortgages they issued. Over the past 60 years, a variety of financial innovations have gradually made it possible for lenders to sell the right to receive the payments on the mortgages they issue, through a process called securitization. The resulting securities are called mortgage backed securities (MBS) and collateralized debt obligations (CDO). Most American mortgages are now held by mortgage pools, the generic term for MBS and CDOs. Of the $10.6 trillion of USA residential mortgages outstanding as of midyear 2008, $6.6 trillion were held by mortgage pools, and $3.4 trillion by traditional depository institutions.

This "originate to distribute" model means that investors holding MBS and CDOs also bear several types of risks, and this has a variety of consequences. There are four primary types of risk:

1. Credit risk - the risk that the homeowner or borrower will be unable or unwilling to pay back the loan;
2. Asset price risk - the risk that assets (MBS in this case) will depreciate in value, resulting in financial losses, markdowns and possibly margin calls;
3. Liquidity risk - the risk that a business entity will be unable to obtain financing, such as from the commercial paper market; and
4. Counterparty risk - the risk that a party to a contract will be unable or unwilling to uphold their obligations.

The aggregate effect of these and other risks has recently been called systemic risk, which refers to when formerly uncorrelated risks shift and become highly correlated, damaging the entire financial system.

When homeowners default, the payments received by MBS and CDO investors decline and the perceived credit risk rises. This has had a significant adverse effect on investors and the entire mortgage industry. The effect is magnified by the high debt levels (financial leverage) households and businesses have incurred in recent years. Finally, the risks associated with American mortgage lending have global impacts, because a major consequence of MBS and CDOs is a closer integration of the USA housing and mortgage markets with global financial markets.

Investors in MBS and CDOs can insure against credit risk by buying credit defaults swaps (CDS). As mortgage defaults rose, the likelihood that the issuers of CDS would have to pay their counterparties increased. This created uncertainty across the system, as investors wondered if CDS issuers would honor their commitments.

Subprime Mortgage Crisis: The Mortgage Market

Subprime lending is the practice of lending, mainly in the form of mortgages for the purchase of residences, to borrowers who do not meet the usual criteria for borrowing at the lowest prevailing market interest rate. These criteria pertain to the downpayment and the borrowing household's income level, both as a fraction of the amount borrowed, and to the borrowing household's employment status and credit history. If a borrower is delinquent in making timely mortgage payments to the loan servicer (a bank or other financial firm), the lender can take possession of the residence acquired using the proceeds from the mortgage, in a process called foreclosure.

The value of USA subprime mortgages was estimated at $1.3 trillion as of March 2007, with over 7.5 million first-lien subprime mortgages outstanding. In the third quarter of 2007, subprime ARMs making up only 6.8% of USA mortgages outstanding also accounted for 43% of the foreclosures begun during that quarter. By October 2007, approximately 16% of subprime adjustable rate mortgages (ARM) were either 90-days delinquent or the lender had begun foreclosure proceedings, roughly triple the rate of 2005. By January 2008, the delinquency rate had risen to 21%. and by May 2008 it was 25%.

The value of all outstanding residential mortgages, owed by USA households to purchase residences housing at most 4 families, was US$9.9 trillion as of yearend 2006, and US$10.6 trillion as of midyear 2008. During 2007, lenders had begun foreclosure proceedings on nearly 1.3 million properties, a 79% increase over 2006. As of August 2008, 9.2% of all mortgages outstanding were either delinquent or in foreclosure. 936,439 USA residences completed foreclosure between August 2007 and October 2008.

Subprime Mortgage Crisis: Background

The crisis began with the bursting of the United States housing bubble and high default rates on "subprime" and adjustable rate mortgages (ARM), beginning in approximately 2005–2006. Government policies and competitive pressures for several years prior to the crisis encouraged higher risk lending practices. Further, an increase in loan incentives such as easy initial terms and a long-term trend of rising housing prices had encouraged borrowers to assume difficult mortgages in the belief they would be able to quickly refinance at more favorable terms. However, once interest rates began to rise and housing prices started to drop moderately in 2006–2007 in many parts of the U.S., refinancing became more difficult. Defaults and foreclosure activity increased dramatically as easy initial terms expired, home prices failed to go up as anticipated, and ARM interest rates reset higher. Foreclosures accelerated in the United States in late 2006 and triggered a global financial crisis through 2007 and 2008. During 2007, nearly 1.3 million U.S. housing properties were subject to foreclosure activity, up 79% from 2006.

Financial products called mortgage-backed securities (MBS), which derive their value from mortgage payments and housing prices, had enabled financial institutions and investors around the world to invest in the U.S. housing market. Major banks and financial institutions had borrowed and invested heavily in MBS and reported losses of approximately US$435 billion as of 17 July 2008. The liquidity and solvency concerns regarding key financial institutions drove central banks to take action to provide funds to banks to encourage lending to worthy borrowers and to restore faith in the commercial paper markets, which are integral to funding business operations. Governments also bailed out key financial institutions, assuming significant additional financial commitments.

The risks to the broader economy created by the housing market downturn and subsequent financial market crisis were primary factors in several decisions by central banks around the world to cut interest rates and governments to implement economic stimulus packages. These actions were designed to stimulate economic growth and inspire confidence in the financial markets. Effects on global stock markets due to the crisis have been dramatic. Between 1 January and 11 October 2008, owners of stocks in U.S. corporations had suffered about $8 trillion in losses, as their holdings declined in value from $20 trillion to $12 trillion. Losses in other countries have averaged about 40%. Losses in the stock markets and housing value declines place further downward pressure on consumer spending, a key economic engine.[9] Leaders of the larger developed and emerging nations met in November 2008 to formulate strategies for addressing the crisis.

Subprime mortgage crisis

The subprime mortgage crisis is an ongoing financial crisis triggered by a dramatic rise in mortgage delinquencies and foreclosures in the United States, with major adverse consequences for banks and financial markets around the globe. The crisis, which has its roots in the closing years of the 20th century, became apparent in 2007 and has exposed pervasive weaknesses in financial industry regulation and the global financial system.

Many USA mortgages issued in recent years are subprime, meaning that little or no downpayment was made, and that they were issued to households with low incomes and assets, and with troubled credit histories. When USA house prices began to decline in 2006-07, mortgage delinquencies soared, and securities backed with subprime mortgages, widely held by financial firms, lost most of their value. The result has been a large decline in the capital of many banks and USA government sponsored enterprises, tightening credit around the world.
