Credit Crunch - Nov 05, 2007
It’s all over the news, we see investment banks
all around the world losing billions because of subprime and credit crunch and
the sporadic use of the word “CDO” in between. For the finance illiterate this
is the most cryptic any news headline can get. In fact, few finance experts
actually know what it means.
How is possible to lose $8 billion and notice it
last minute?
Common agreement is to blame a real estate bubble
that provoked billions in loses, and although true, this is only part of the
story. The real problem is the use of derivatives (alias weapons of mass
destruction as Warren Buffet called them) and how investment banks, rating
agencies and hedge funds manipulated them to gain quick profit.
To my friends I’m talking geek speak, so let me
explain how this all works using human language.
Let’s suppose you are an online used cars seller
“CARS A FULL”. You want to sell 100 Mercedes D this month. This will be a
simulated scenario for the sell:
-
You go to ebay and search for
the model you are trying to sell. See similar sales and come up with an average
sell price of $25000 (I have no idea about cars so bare with me). You also see a
lot of people asking for a Mercedes D and willing to buy at that price.
-
Knowing the average sell
price, you call up your dealer and ask for 100 Mercedes. If the dealer gives you
a price of $25000 or more, you know it’s not worth the effort to even try this
whole sell, they either lower the price or you don’t want the deal.
Pretty simple, this is more or less how you trade
stocks. You have an index where you see the average bid/ask price (sell price)
of shares, so you know you can buy or sell Microsoft at certain amount. There is
no doubt about it, if you were to execute the sell at this moment you know how
much money you’ll be getting. It’s an open market and very liquid: you can sell
almost instantaneously and everybody sees the price you are willing to buy or
sell for.
Now, let’s go back to the online used cars seller
example. Imagine now that ebay doesn’t exist. No online site where you can
actually see what’s the average price or how many people is willing to buy a
Mercedes D. Things get a little interesting. You know for sure people want a
Mercedes D, there is definitely market for it but you need to figure out a fair
value. You neither want to sell cars at a lost nor set a price too high for
anyone to buy them.
What do you do? Well, you hire 5 people that all
they do is randomly call customers, potential buyers and recent buyers to try to
figure out the current cars' value.
This is the situation with banks and CDOs. There
is no common place where they can all look and see a price. Most of the time,
this actually works to their advantage because customers can’t see others banks
prices and they can rip customers off easily.
Business is good and several years later your
monthly sells has grown from 100 to 2000 cars. But competition is fierce against
200 other car dealers around your area. Not only that, sometimes a couple of
cars come defectious and you lose money because you can’t sell those for a
profit. Other times the car comes with 0 miles of usage, completely like new but
you already agreed to sell them at certain price and you could had made more
profit. You need an edge in the business.
You think about it and come up with a great idea.
You call up your dealer and put a condition on him: He has to hire an
independent rating company that will check the cars and notify of their
conditions. Depending on their usage, scratches, miles, defects and so on they
can get ratings ranging from AAA to DDD. This will help you to know beforehand
which cars are in what conditions.
Now you hire a team of experts that write the
“cars model book”. In this book, given the year of manufacture, miles and rating
(AAA-DDD) of the car, you can come up quickly with an estimated sale price.
CARS A FULL is rocking, every first of the month
you order a couple hundred cars, the dealer gives you a list of car’s ratings
and prices. You look up in your cars model book what is a good sell price and
either accept or reject the dealer’s offer. Business
is good, the idea is brilliant and soon it catches up with other cars sellers.
They also start requiring a third party rating agency and create their own “cars
model book” to get an idea of what is a “good” price. They all pool customers
and other companies to try to see how well their models actually match the
market (practice known as mark to market in finance).
And this is how most banks operate.
So what went wrong?
Back to our online car seller. As the happy owner
of CARS A FULL you wake up a common morning just to see the news: “Manufacturer
of Mercedes D mixed engines and a half of them were sent out to dealers with a
Honda engine”.
You think, this is going to suck for the dealers.
CARS A FULL should be in good standing because the cars pass through the third
party rating company and they are all AAA. Good to go, we are safe.
This couldn’t be further from the truth. You
arrive to the office to find the phone ringing non-stop, your employees going
crazy and a long list of complains. It seems half of your last month sales had
Honda engines. But this is impossible! Pissed at the madness you decide to open
the hood of one of the cars that you were about to ship today. You’ve never
bothered to check any car, you fully trusted your dealer and rating agency, but
to your surprise you find a Honda inside the Mercedes.
Things get worse. One employee comes running to
you with a printed page from the New York Times. It appears that some Mercedes D
were shipped with the right engine but they got a defectuous steering wheel that
might get stuck during driving if not exchanged. In addition, the only way to
detect the steering problem is with special equipment and expertise which you
don’t have and can’t get at the time. So not only you have Hondas in your garage
but you might have defected steering wheels with no way to tell them apart.
More news come in: “Rating agencies purposely
‘failed’ to detect the issues because of shared commissions with dealers.” Now
you know what happened. The dealer wanted to sell the cars, they hired rating
agencies to inspect the cars. Dealers wanted to get the better prices with
better ratings so they offered commission to the rating agencies for the amount
of sales. It was convenient for the agencies to fail to detect these car issues.
You are fuming. You call up your dealer who
doesn’t pick up the phone. You call the rating agency to find busy signal. You
are just starting to realize the consequences, you got more than 1000 cars in
your garage to sell and you can’t price them correctly. Your “cars model book”
is useless without the correct input data. You need to first find out the
situation of every single car in your garage. This is going to be expensive but
it’s the only way to get out of the hole, or so you believe. After spending an
extraordinary amount of money to figure the cars’ condition, you find out you
can’t sell them at the price your book is suggesting. The word has spread on the
market and all other online car sellers are in the same situation, all your
competitors are in trouble too and nobody wants to buy Mercedes D because they
are afraid to get a Honda or a defected steering wheel. Your book is clearly
useless at this moment and you can’t figure out a good sell price.
You only have an option, try to sell a couple cars
and see what they sell for. (Mark to market). You put some cars out for sale and
you don’t see any bids coming in. You know your cars are not worthless but there
is no offers at the moment so you have no clue what a decent sale price is.
There is no liquidity, you are trying to sell completely blind.
This is the current situation at banks. They got
into the business of selling and buying derivatives without checking under the
hood. The business was doing great and earnings skyrocketed but they based their
models in incorrect input. When the news about mortgages defaults broke, they
found that their supposedly safe AAA investments were in reality BBB or CCC and
they tried to get rid of them as fast as possible just to realize that the whole
finance industry was under the same umbrella. Every investment bank wanted a way
out but nobody wanted to buy. The federal reserve tried to add billions to add
liquidity but it hasn’t help much. Nobody wants to buy unknown instruments with
high risk and the people selling are selling way undervalued, losing billions in
the process.
Whose fault is it? The rating agencies who ignored
the warnings? The dealers who looked left while this happened just to get a nice
paycheck? Or the seller that didn’t bother to open the hood and sold cars
without having some basic knowledge?
They all had their part on it and they are all
trying to recover their losses, praying for the fed to come to their rescue. If things get worse politicians will try to regulate this
largely unregulated business, but for now, these are interesting times to be in the
financial industry.
