Subprime Mortgage: The Cause of 2008 Financial Crisis Explained

It’s been more than a decade since 2008 financial crisis – originated in USA. Since then, there has been several publications pointing at the causes of the crisis. The most common cause is assigned to ‘subprime mortgage‘.

Subprime mortgage refers to Mortgage Backed Securities (MBS), but of a very special category. We will read more why I’m referring it as ‘very special’.

It was “Lew Ranieri” who first coined the theory of securitisation of mortgages. This eventually let to the formation of our modern day ‘mortgage backed securities’. So first blame of the crisis must be on him. 🙂

In theory, Lew Ranieri can be blamed. But practically there were series of mistakes, ignorances, and malpractices which eventually led to the global crisis.

In this article we will try to discuss the chain of activities which gave birth to subprime mortgages, which in turn caused the 2008 financial crisis.

Allow me to explain the events in a sequential manner.

Subprime Mortgage

To understand what is subprime mortgage, it is essential to know the scheme of things about how the mortgage business operates in US. Once we are clear about this flow – we can pin point & understand the root cause of crisis.

Subprime mortgage is the root cause. But it is also important to appreciate the ripple effect caused by the subprime mortgage, which eventually led to the 2008 financial crisis.

Here are few terms (concepts) explained in brief, which is necessary to remember to understand the enormity of subprime mortgage.

  • Mortgage: It is a loan taken from bank to buy a house. It is an agreement between homebuyers and banks. The homebuyer agrees to payback money to the bank over time. The payback will be the principal amount plus interest. Till such time, the ‘house’ remains as lien with the borrower.
  • Bank’s: There are two types of banks which are involved. First, are the retail banks which lends money to the borrowers. Second, type is the investment banks to whom, the retail banks eventually sell the loans. We’ll read more about this in this article.
  • Bonds: These are fixed income, risk free investment options. They can generate very predictable returns. Why? Because they are backed by US Treasury Department. But on downside, their yields are low. Few examples of it are, treasury bonds etc.
  • Mortgage Backed Security (MBS): These are like bonds. Their shares are also traded in secondary market. But the only difference is that, they pose a bigger risk of loss (compared to government bonds). Hence, to compensate this risk, they offer higher returns.
    • What is MBS: All mortgages bought by investment banks are clubbed together, and a MBS is formed. What is MBS? It is a financial instrument whose assets are ‘loan agreements’. Why it is called an asset? Because loans generate income inform of ‘monthly payments’ – which the borrowers regularly pays to bank.
    • Types of MBS: The way mortgages are clubbed, gives birth to different types of MBS’s. Example: one type of MBS will include those mortgages whose borrowers profile has credit score above 720 (prime borrowers). Another MBS may be formed whose credit profile is below 700.
    • Investment in MBS: MBS shares are traded in secondary market. Interested people can buy and sell shares of MBS (like stocks). There will be some investors who will buy only MBS>720. There will be some investors who are willing to take more risks, will even buy MBS<700. Why? Because in normal times, riskier investment can fetch higher returns.
    • Subprime mortgage: Those Mortgage Backed Securities whose borrower’s risk profile is too low (example MBS < 650) is classified as subprime mortgage.
  • Loan for everyone: In a MBS backed mortgage market, anyone can get a loan. Suppose there is an MBS whose borrowers risk profile is below 650. In traditional banking, people with score below 650 will not get a loan. But in MBS market, even these people can get loan – till this MBS’s shares has buyers in the Wall Street.

Now with these concepts known to us, we are ready to listen to the story about the cause of 2008 financial crisis. This story will explain in simple language the sequence of reasons which led the U.S. economy to 2008 financial crisis

1. Mortgages

subprime mortgage - 2008 Financial Crisis cause - Mortgage

People seeking to buy homes, approach retail banks and ask for a loan. The loan application is filled and submitted to the bank.

These banks in turn checks the credentials of the borrower. If the borrower pass their minimum criteria, the loan will be issued.

A person who has a steady job/business, high income, and good credit score (like above FICO 720) will get loan easily and at a lower interest rate compared to others.

People with lower FICO score may not get a loan. They also might get a loan, but for them the criteria will be stringent – like larger downpayment, higher interest rates, shorter loan duration etc.

But here also the banks will have a bare minimum criteria. If a person is not falling in this criteria, he/she can forget about the loan.

2. Involvement of Investment Banks

subprime mortgage - 2008 Financial Crisis cause - Investment Bank

In traditional banking, there are only two agencies dealing with loans – borrower and lender (homebuyer and retail bank). But since year 2000’s, a third party got involved – investment banks.

These investment banks started buying the “mortgage agreements” from the retail banks. This way, they became entitled to receive the monthly payments from the borrowers.

The role of retail banks became substantially marginalised. Their responsibility was limited to issuance of loan only. After this step, their job was to sell the loans to investment banks. Period.

Henceforth, it was investment banks who became the holder of the mortgage agreements.

Why retail banks sold the loans? Because this way, their balance sheet had zero liability, and only cash asset (received from investment bank).

Why investment banks bought loans? To use them as Mortgage Backed Security (MBS).

3. Need for Mortgage Backed Security (MBS)

In year 2000’s, the yield of government back securities (like treasury bonds) very low. All risk free, fixed income instruments were yielding very low yield. Hence bankers were busy inventing a low risk – high return investment option. This gave rise to mortgage backed security (MBS).

As MBS had ‘mortgage loans’ as their assets, it was considered safe. At a time when treasury bills were yielding less than 3.5% returns, MBS could promise 5-6% fixed returns.

4. How investment banks made money?

subprime mortgage - 2008 Financial Crisis cause - Investment Bank Made Money

Investment banks bought loans from retail banks. Several such mortgages were clubbed together to form a Mortgage Backed Security (MBS). This MBS was valued based on its future income potential.

What is the future income of MBS? Monthly payments received from the homebuyers.

Suppose there is a MBS whose net worth is $1Billion. This MBS is divided into equal one billion number shares. It means, each share of MBS is valued at $1 (net worth / no of shares). These shares of MBS were then traded in secondary market (Wall Street).

Suppose, each shares of MBS were sold at an average price of $1.2. It means, the MBS could generate a funds of $1.2 Billion ($1.2 x 1 billion number shares).

The investment bank paid a total of $1 billion to buy mortgages from retail banks. Through shares issue, they earned $1.2 Billion. Gross earnings of the investment bank is $0.2 Billion.

5. How investors of MBS made money?

subprime mortgage - 2008 Financial Crisis cause - Investors Made Money

Suppose there is a MBS which was worth $1 billion. It was capable of earning $57.2 million p.a. for next 30 years.

From where this earning was coming? From the monthly payments made by the borrowers again their mortgages.

These monthly payments received by the investment bank (MBS), will be proportionately distributed among the investors in proportion to their shareholdings. If there are one billion number shares, then income per share of this MBS will be $0.0572.

  • What will be the yield per share for the investors?
    • Share Price: $1.2 per share.
    • Income: $0.0572.
    • Yield: 4.77% (0.0572 / 1.2).

It means, by buying a share of MBS, the investor will earn a return of 4.77% upon his/her investment.

6. Over demand for MBS

Till loans were issued to credit worthy borrowers, mortgage backed security market flourished. It was a perfect investment vehicle for matured economies (like USA, UK, Australia etc). The demand for MBS skyrocketed.

To feed the rising demand, MBS needed more mortgages. But the problem was, credit worthy borrowers in America are only limited.

In this scenario, the retail banks tweaked their lending criteria. They started issuing loans to even not so credit worthy borrowers.

But they charged higher interest rates on such loans.

Then a stage came when demand of MBS further grew. Retail and commercial banks, wanted to match the pace. Hence, they started issuing loans without even verifying the credentials of the borrowers.

This way, list of borrowers were rising at a desired pace.

7. Collateralised Debt Obligations (CDO’s)

subprime mortgage - 2008 Financial Crisis cause - Mortgage Backed Security MBS

When retail banks started issuing loans to less credit worthy borrowers, investment banks knew the risk. They could gauge that these borrowers have high chance of defaulting. The overall credit ratings of MBS’s were dangerously low (like B+, CCC and below).

Hence, what they did was to create another investment vehicle called CDO’s. These CDO’s had a mix of mortgage backed securities:

  • Prime mortgages (Credit Rating A to AAA)
  • Subprime mortgages (Credit Rating A- and below).

This helped them to hide the so called “subprime mortgages” under the blanket of prime mortgages.

Moreover, the buyers of CDO’s were not common men. They were purchased mainly by hedge funds, investment banks themselves, pension funds etc.

Hence the public audit of subprime mortgages could be prevented. Investment banks could keep it hidden for extended period of time.

Nevertheless, investment banks were not so bothered. Why? Because there was a market for such MBS’s and CDO’s. People were buying its shares with open arms.

8. Booming Real Estate Market

subprime mortgage - 2008 Financial Crisis cause - Property Price Growth

As more people were becoming eligible for the mortgage, the demand for homes started increasing. More people had money (borrowed) to buy a new home.

This created a price bubble in the real estate sector. The price of residential properties only went up. In such a booming market, a pretence was building that nothing can go wrong with MBS’s. How?

What was the income source for MBS? Monthly payments made by the borrowers against mortgage loan. The risk of loss here was only when the borrowers fail to make payments (loan default).

For the MBS market, this was not a problem, why? Because the property which was used as a collateral – could be sold to make up for the loss.

This assumption was not wrong – but it remained true only till the property prices was only moving upward.

9. Role of Other Agencies

There were two agencies whose contribution could not be underestimated in the rise of subprime mortgage. Involvement of these two agencies only added to the false euphoria related to subprime mortgages.

  1. Credit Rating Agencies

    The credit rating agencies (Moody, S&P, Fitch etc) gave AAA ratings to most of MBS’s – even when loans were issued to subprime borrowers. They gave high ratings based on the past historical data. But what they missed was that in recent times, the mortgages were issued to any and everyone.

  2. Credit Default Swaps (Insurance)

    This was another financial instrument which compounded the negative effect of subprime mortgage. Credit default swaps are basically insurance cover for the MBS. They protected the MBS against any loss in revenue due to ‘loan defaults’ or ‘prepayments’. As the MBS’s were insured, investors had that false sense of protection.

In 2008-09, majority borrowers were defaulting on loans. The insurance companies (Like AIG) could not cover this urgency. They also declared themselves as bankrupt.

10.Why people were taking loans?

In those times, even those people who had no source of income were getting loans to buy home. These people had near zero capability to payback the mortgage, but they still took the loan. Why?

Their logic was, as the price of homes were only going up, they can use it to their advantage. Example: Take a $100,000 loan, and buy a home. After few months sell the home for $102,000. Use the sale proceeds to pay back the loan, and pocket the balance as profit.

People were taking mortgages to do trading of real estate properties. To help such borrowers, banks offered incentives. The loans had lower monthly payments for the first few months.

12. Bursting of the housing bubble

A stage was reached in the US housing market where the borrowers started defaulting on their loans. Why the default? Because it was inevitable. How?

The cause was subprime mortgages. The loans were issued to people who had little capability to payback the loan. Hence, they eventually could not afford the ‘monthly payments’ – and their property went for foreclosure.

At a point in 2007-2008, there were more houses on sale than there were buyers for it. This triggered a steady price fall. The housing bubble bursted.

13. More Bad Loans

subprime mortgage - 2008 Financial Crisis cause - Mortgage More than Property Value

When property prices started going down, people who had bought the property with the sole purpose of “buying low and selling high” stopped paying the mortgage. Why?

Because their property value started becoming smaller than the mortgage value. This led to more loan defaults, leading to more foreclosures. This further brought down the real estate prices.

14. Big Investors

When financial institutions saw this trend of falling prices, they became defensive. They stopped buying shares of ‘subprime mortgage backed security’.

Instead, they started doing the reverse. They started dumping their already held shares of those CDO’s which had subprime mortgages as their assets.

As a result, the share price of MBS’s started to fall steeply. This eventually started to reflect on the wall street.

Who were these big investors? They were investment banks like Lehman Brothers, Bear Sterns etc.

This way the earnings of investment banks (MBS’s) stopped, and eventually they had to declare themselves as bankrupt.

15. Recession

The panic first spread across common Americans, and then across the world. The stock market crashed, and the credit market froze.

Loans became almost impossible to get. The economies across the world became cash starved. In absence of sufficient liquidity, growth rates became negative.

Due to negative sentiments, public spending was also falling. This eventually led to the recession.

Conclusion

To sum up the whole story, allow me to list down the main causes which led to the formation of subprime mortgage and eventually to 2008 financial crisis:

  • Bad Loans: The root cause of the crisis was “bad loans”. Had the retail banks checked themselves from issuing bad loans, subprime mortgage backed securities based CDO’s would have never been born.
    • Why retail banks issued bad loans? Because they knew that, the responsibility of bad loans will not be on them (it will be on investment banks). Their risk of loss was almost zero. Moreover, there was demand for subprime mortgages, and they also fetched higher interest rates for the banks
  • Investment Banks: Formation of CDO with subprime mortgages was their first mistake. Their second mistake (which also amounts to crime), is hiding the true credit rating of the CDO’s and MBS’s.
  • Insurance Companies: Insurance cannot be sold to anyone. Like a cancer patient will not be able to buy a health insurance, similarly an unhealthy CDO’s should not have got the protection of Credit Default Swaps.
  • Bailout: USA’s economy is huge. It is so big that, even a small change here effects the economies around the globe. On top of this, in modern economy, banks just cannot fail. Too many people are dependent, on even basic functions of banks. Hence, at the back of the mind, the banks knew that US congress will eventually bail them out.
  • Congress & SEC: First it was US congress who restricted the powers of SEC over regulation of MBS, CDO’s and Credit Default Swaps. The Department of Justice (DOJ) also kept quite seeing the wrongdoings by congress and SEC.
  • People: It will not be wrong to say that common people also contributed to the mess of subprime mortgage. People who knew that they will not be able to pay the ‘monthly payments’ of the mortgage, should not have taken the loan in first place. Their greed for easy money made the matter worse.

Final Words

What we have learned from the subprime mortgage crisis? Probably little.

After 2008 financial crisis, subprime mortgage vanished from the US market. There were too many critical eyes, watching the next steps of the investment banks.

Even SEC was acting tough on retail banks who were the first window to issue loans to the public. But today in 2019, the may be the banks has found another loophole in the law-books.

A very similar type of loan is again being issued to Americans. Instead of calling it as ‘subprime mortgage’, it has been rebranded as ‘student loan debt‘.

Principally, student loan debt is not a bad thing. But when the size of this debt is touching a $1.5 Trillion, it raises questions.

What is more worrying about student loan debt is its ‘burden’ on students. As on 2019, it is said that 44 million students have availed student loans. On an average, each student is carrying a loan burden of $32,000.

To start a career with this kind of burden is a concern.
