Can You Short the Mortgage Market Again
This article will explain the Big Short and the 2008 subprime mortgage plummet in simple terms.
This post is a piddling longer than usual–peradventure give yourself 20 minutes to sift through information technology. But I promise you'll leave feeling like you can tranche (that'due south a verb, right?!) the whole financial organization!
Key Players
First, I desire to introduce the players in the financial crisis, as they might not brand sense at offset blush. One of the worst parts about the financial industry is how they use deliberately obtuse language to explain relatively uncomplicated ideas. Their financial acronyms are hard to continue rails of. In guild to explain the Big Short, these players–and their roles–are fundamental.
Individuals, a.g.a. regular people who take out mortgages to buy houses; for example, you and me!
Mortgage lenders, similar a local bank or a mortgage lending specialty shop, who give out mortgages to individuals. Either fashion, they're probably local people that the individual abode-buyer would run into in person.
Largebanks, such every bit Goldman Sachs and Morgan Stanley, who buy lots of mortgages from lenders. After this transaction, the homeowner would owe coin to the big bank instead of the lender.
Collateralized debt obligations (CDOs)—deep breath!—who have mortgages from big banks and packet them all together into a bond (see beneath). And but like before, this step means that the dwelling house-buyer now owes coin to the CDO. Why is this done?! I'll explain, I hope.
Ratings agencies, whose job is to determine the gamble of a CDO—is it filled with condom mortgages, or risky mortgages?
Investors, who buy part of a CDO and get repaid equally the individual homeowners start paying back their mortgage.
Feel lost already? I'm going to be a good jungle guide and get y'all through this. Stick with me.
Quick definition: Bonds
A bond can be idea of equally a loan. When you buy a bond, you are loaning your money. The issuer of the bond is borrowing your money. In substitution for borrowing your money, the issuer promises to pay you back, plus involvement, in a certain amount of fourth dimension. Sometimes, the borrower cannot pay the investor back, and the bond defaults, or fails. Defaults are not proficient for the investor.
The CDO—which is a bond—could hold thousands of mortgages in it. Information technology's a mortgage-backed bond, and therefore a blazon of mortgage-backed security. If you bought i% of a CDO, you were loaning money equivalent to one% of all the mortgage principal, with the hope of collecting 1% of the principal plus involvement every bit the mortgages got repaid.
There'southward i more key player, but I'll wait to introduce it. Showtime…
The Whys, Explained
Why does an individual take out a mortgage? Because they desire a home. Can you arraign them?! A salubrious housing market involves people buying and selling houses.
How about the lender; why do they lend? It used to exist and so they would slowly make involvement money as the mortgage got repaid. Simply nowadays, the lender takes a fee (from the homeowner) for creating (or originating) the mortgage, and and then immediately sells to mortgage to…
A large depository financial institution. Why exercise they buy mortgages from lenders? Starting in the 1970s, Wall St. started buying upwardly groups of loans, tying them all together into ane bond—the CDO—and selling slices of that collection to investors. When people buy and sell those slices, the big banks get a cut of the activity—a commission.
Why would an investor want a slice of a mortgage CDO? Because, like any other investment, the large banks promised that the investor would brand their money back plus interest once the homeowners began repaying their mortgages.
You can about trace the flow of money and risk from player to histrion.
At the finish of the day, the investor needs to get repaid, and that money comes from homeowners.

CDOs are empty buckets
Homeowners and mortgage lenders are easy to understand. But a large question mark swirls around Wall Street's CDOs.
I like to think of the CDO as a football game field full of empty buckets—one bucket per mortgage. As an investor, you don't buy one unmarried bucket, or 1 mortgage. Instead, yous purchase a thin horizontal piece across all the buckets—say, a half-inch slice right around the 1-gallon marker.
Every bit the mortgages are repaid, it starts raining. The repayments—or rain—from Mortgage A doesn't go solely into Bucket A, but rather is distributed across all the buckets, and all the buckets slowly get re-filled.
As long as your horizontal slice of the bucket is somewhen surpassed, you become your money back plus involvement. You don't need every mortgage to be repaid. You just need enough mortgages to get to your slice.
Information technology makes sense, so, that the tippy top of the bucket—which gets filled upwardly terminal—is the highest risk. If too many of the mortgages in the CDO neglect and aren't repaid, then the tippy pinnacle of the bucket will never get filled up, and those investors won't get their coin dorsum.
These horizontal slices are called tranches , which might audio familiar if yous've read the book or watched the movie.
So far, there's cipher too wrong nearly this practice. It's but moving the risk from the mortgage lender to other investors. Sure, the middle-men (banks, lenders, CDOs) are all taking a cut out of all the buy and sell transactions. Merely that's no different than ownership lettuce at grocery store prices vs. ownership direct from the farmer. Middle-men take a cut. Information technology happens.
But now, our last thespian enters the stage…
Credit Default Swaps: The Lynchpin of the Big Brusk
Screw you, Wall Street nomenclature! A credit default swap sounds complicated, simply it's just insurance. Very unproblematic, but they have a key function to explain the Big Brusk.
Investors thought, "Well, since I'grand buying this risky tranche of a CDO, I might want to hedge my bets a chip and buy insurance in case it fails." That's what a credit default bandy did. Information technology'due south insurance confronting something failing. Simply, in that location is a vital divergence between a credit default swap and normal insurance.
I tin can't buy an insurance policy on your house, on your auto, or on your life. Only you can buy those policies. But, I could buy insurance on a CDO mortgage bond, even if I didn't own that bail!
Not only that, just I could purchase billions of dollars of insurance on a CDO that only contained millions of dollars of mortgages.
Information technology'southward like taking out a $1 million motorcar policy on a Honda Borough. No insurance visitor would let y'all to practise this, but it was happening all over Wall Street earlier 2008. This scenario essentially is "the large curt" (come across beneath)—making huge insurance bets that CDOs volition fail—and many of the big banks were on the wrong side of this bet!
Credit default swaps involved the largest amounts of money in the subprime mortgage crisis. This is where the big Wall Street bets were taking place.
Quick definition: Short
A brusk is a bet that something will fail, get worse, or become downward. When most people invest, they buy long ("I desire this stock price to go up!"). A short is the opposite of that.
Sure individuals—like main characters Steve Eisman (aka Mark Baum in the movie, played past Steve Carrell) and Michael Burry (played past Christian Bale) in the 2015 Oscar-nominated film The Big Short—realized that tons of mortgages were beingness fabricated to people who would never be able to pay them back.
If enough mortgages failed, then tranches of CDOs start to neglect—no mortgage repayment means no rain, and no pelting means the buckets stay empty. If CDOs fail, so the credit default swap insurance gets paid out. So what to exercise? Buy credit default swaps! That'southward the quick and dingy way to explain the Large Curt.
Why purchase Dog Shit?
Look a second. Why did people originally invest in these CDO bonds if they were full of "dog shit mortgages" (direct quote from the book) in the first identify? Since The Big Short protagonists knew what was happening, shouldn't the investors also have realized that the buckets would never get refilled?
For one, the prospectus—a fancy word for "owner'south manual"—of a CDO was very difficult to parse through. It was hard to sympathize exactly which mortgages were in the CDO. This is a skeevy big depository financial institution/CDO do. And fifty-fifty if you lot knew which mortgages were in a CDO, information technology was nearly impossible to realize that many of those mortgages were made fraudulently.
The mortgage lenders were knowingly creating bad mortgages . They were giving loans to people with no hopes of repaying them. Why? Because the lenders knew they could immediately sell that mortgage—that risk—to a big bank, which would and then securitize the mortgage into a CDO, and and then sell that CDO to investors. Whatsoever risk that the lender took by creating a bad mortgage was quickly transferred to the investor.
So…because you tin can't decipher the prospectus to tell which mortgages are in a CDO, it was easier to rely on the CDO's rating than to evaluate each of the underlying mortgages. Information technology's the aforementioned reason why yous don't take to sympathise how engines work when you buy a car; you lot just look at Car & Driver or Consumer Reports for their opinions, their ratings.
The Ratings Agencies
Investors often relied on ratings to determine which bonds to purchase. The ii most well-known ratings agencies from 2008 were Moody'south and Standard & Poor's (heard of the Southward&P 500?). The ratings agency's chore was to expect at a CDO that a big bank created, understand the underlying assets (in this case, the mortgages), and requite the CDO a rating to determine how rubber it was. A adept rating is "AAA"—so nice, information technology got 'A' thrice.
And so, were the ratings agencies doing their jobs? No! There are a few explanations for this:
- Even they—the experts in accuse of grading the bonds—didn't sympathize what was going on inside a CDO. The possessor's manual descriptions (prospectuses) were too complicated. In fact, ratings agencies frequently relied on big banks to teach seminars about how to charge per unit CDOs, which is like a teacher learning how to grade tests from Timmy, who still pees his pants. Timmy just wants an A.
- Ratings agencies are turn a profit-driven companies. When they requite a rating, they charge a fee. But if the agency hands out also many bad grades, then their customers—the big banks—will have their requests elsewhere in hopes of higher grades. The ratings agencies weren't objective, but instead were biased by their need for profits.
- Remember those fraudulent mortgages that the lenders were making? Unless you did some boots-on-the-ground research, it was tough to uncover this fact. It'southward difficult to blame the ratings agencies for not catching this.
Who's to blame?
Everyone? Permit'south play devil's advocate…
- Individuals: some people point the finger at homeowners, maxim, "Yous should know better than to buy a $1 one thousand thousand firm on a teacher's bacon." I notice this hard to swallow. These people, surrounded by the American domicile-ownership dream, were sold the thought that they would be fine. The mortgage lender had no incentive to sell a good mortgage, they only had an incentive to sell a mortgage. So, it's hard for me to put also much blame on the homeowners.
- Mortgage lenders: someone knew. I'1000 not proverb that all the mortgage lenders were fully aware of the implications of their actions, only some people knew that fraudulent loans were being made, and chose to ignore that fact. For example, check out whistleblower Eileen Foster.
- Large banks: Yes sir! In that location's certainly blame here. Rather than go into all of the diverse coin-grubbing, I want to call out i specific anecdote. Back in 2010, Goldman Sachs CEO Lloyd Blankfein testified in front of Congress. Here information technology is:
To explain farther, in that location are two things going on here.
First, Goldman Sachs bankers were selling CDOs to investors. They wanted to brand a committee on the sale.
At the aforementioned time, other bankers ALSO AT GOLDMAN SACHS were buying credit default swaps, a.one thousand.a. betting against the same CDOs that the outset Goldman Sachs bankers were selling.
This is similar selling someone a racehorse with cancer, and then immediately going to the track to bet confronting that horse. Blankfein's defense force in this video is, "But the horse seller and the bettor weren't the same people!" And the Congressmen responds, "But they worked for the same stable, and collected the aforementioned paychecks!"
So practice the big banks deserve blame? You tell me.
Inspecting Goldman Sachs
Ane reason Goldman Sachs survived 2008 is that they began buying credit default swaps (insurance) merely in fourth dimension before the housing market crashed. They were nonetheless on the bad side of some bets, but mostly on the adept side. They were net profitable.
Unfortunately for them, the banks that owed Goldman coin were going bankrupt from their ain debt, and then Goldman never would have been able to collect on their insurance. Goldman would've had to payout on their "bad" bets, while not collecting on their "good" bets. In their own words, they were "toast."
This is significant. Even banks in "good" positions would've gone bankrupt, considering the people who owed the nigh money weren't able to repay all their debts. Imagine a chain; Bank A owes money to Bank B, and B owes money to Bank C. If Banking company A fails, then B can't collect their debt, and B can't pay C. Bank C made "good" bets, merely aren't able to collect on them, and then they go out of business.
These failures would've rippled throughout the world. This explains why the US government felt it necessary to bond-out the banks. That federal money allowed banks in "good" positions to collect their profits and "finish the ripple" from tearing autonomously the world economy. While CDOs and credit default swap explicate the Big Brusque starting, this ripple of failure is the mechanism that affected the entire world.
Betting more than than you lot accept
But if someone made a bad bet—sold bad insurance—why didn't they have money to cover that bet? It all depends on risk. If you sell a $100 million insurance policy, and you lot think there's a ane% chance of paying out that policy, what's your exposure? It'due south the potential loss multiplied by the probability = ane% times $100 million, or $i million.
These banks sold billions of dollars of insurance nether the assumption that there was a 5%, or three%, or 1% chance of the housing market declining. So they had 20x, or 30x, or 100x less coin on hand then they needed to embrace these bets.
Turns out, there was a 100% chance that the market would fail…oops!
Blame, expounded
Ratings agencies—they should be unbiased. Only they sold themselves off for profit. They invited the wolves—big banks—into their homes to teach them how to grade CDOs. Possibly they should read a blog to explicate the Big Short to them. Of grade they deserve arraign. Here's some other anecdote of terrible judgment from the ratings agencies:
Think back to my illustration of the buckets and the pelting. Sometimes, a ratings agency would look at a CDO and say, "You're never going to make full these buckets all the way. Those final tranches—the ones that won't get filled—they're actually risky. Then we're going to give them a bad course." There were "Dog Shit" tranches, and Canis familiaris Shit gets a bad class.
But and so the CDO managers would go back to their offices and cut off the height of the buckets. And they'd practise this for all their CDOs—cutting off all the saucepan-superlative rings from all the different CDO buckets. And so they'd super-gum the bucket-top rings together to create a field full of Frankenstein buckets, officially called a CDO squared. Because the Frankenstein buckets were originally function of other CDOs, the Frankenstein buckets could only start filling up once the original buckets (which now had the tops cut off) were filled. In other words, the CDO managers decided to concentrate all their Dog Shit in one place, and super mucilage it together.
A reasonable person would expect at the Frankenstein Dog Shit field of buckets and say, "That's turrible, Kenny."
BUT THE RATINGS AGENCIES GAVE CDO-SQUAREDs High GRADES!!! Oh I'm lamentable, was I yelling?!
"Information technology's diversified," they would claim, equally if Poodle shit mixed with Labrador shit is better than pure Poodle shit.
Once more, you tell me. Do the ratings agencies deserve arraign?!
Does the authorities deserve blame?
Yes and no.
For example, function of the Housing and Community Development Act of 1992 mandated that the government mortgage finance firms (Freddie Mac and Fannie Mae) purchase a certain number of sub-prime mortgages.
On its surface, this seems like a good thing: it's giving money to potential domicile-buyers who wouldn't otherwise authorize for a mortgage. It'south providing the American Dream.
Just as we've already covered today, information technology does nobody any skillful to provide a bad mortgage to someone who can't repay it. That's what caused this whole calamity. Freddie and Fannie and HUD were pumping money into the machine, helping to enable it. Good intentions, but they weren't paying attention to the unintended outcomes.
And what about the Securities & Commutation Commission (SEC), the watchdogs of Wall Street. Do they have a part to explain the Big Brusque? Shouldn't they have been enlightened of the Big Banks, the CDOs, the ratings agencies?
Yes, they deserve blame likewise. They're supposed to do things similar ensure that Big Banks have enough money on hand to cover their risky bets. This is called proper "risk direction," and it was severely lacking. The SEC besides had the power to dig into the CDOs and ferret out the fraudulent mortgages that were creating them. Why didn't they exercise that?
Perhaps the effect is that the SEC was/is only as well close to Wall Street, similar to the ratings agencies getting advice from the big banks. Watchdogs shouldn't get treats from those they're watching. Or maybe information technology's that the CDOs and credit default swaps were likewise hard for the SEC to understand.
Either way, the SEC doesn't accept a practiced excuse. If you lot're in bed with the people you're regulating, and so you're doing a bad job. If you're rubber stamping things you don't sympathise, then y'all're doing a bad job.
Explain the Big Short, soon
You're well-nigh 2500 words into my "short summary." Simply the important things to call back:
- Fiscal acronyms suck.
- Money flowed from the investors down to the mortgage lenders, and the risk flowed from the mortgage lenders up to the investors. In betwixt, the large banks and CDOs acted as middle men and intermediaries.
- When someone feels like their actions have no risk, or no consequences, they'll deport poorly (big banks, mortgage lenders)
When someone is given what seems like an amazing deal, they'll accept it (private domicile owners). - CDOs are like empty buckets. Mortgage payments are like rain, filling the buckets. Investors purchase tranches, or slices, across all the buckets. If mortgages neglect, then the buckets might not fill up upwards, and the investors won't go their coin back.
- CDOs are intentionally complex. And so complex, that not even the people grading them understood what was going on (ratings agencies).
- Buying insurance on something your practice non own is a behavior with potential for abuse (big banks)
- Buying insurance on something for more it'south worth is a behavior with potential for abuse (big banks). This is where about of the money in the financial crunch switched hands.
And with that, I'd like to denote the opening of the Best Interest CDO. Rather than invest in mortgages, I'll be investing in race horses. Don't ask my why, just the current elevation stallion is named 'Domestic dog Shit.' He'll have Wall Street by storm.
