Crisis of Credit Visualized

Really, you should have already seen this. If you're unsure on the whole global credit crisis thing and the root causes of it, this is pretty much the best primer on it I've ever seen.

How Banks Work

Another week, another amazing This American Life episode. This week they tackle the economic crisis for a third time, and they explain things in plain English for everybody to understand in easy terms. They have a great explanation involving how exactly the banks got into trouble. You should listen, but here's a quick and dirty explanation.

Let's make up a bank. We call it "Bank A", and Bank A starts with $10 capital. That means that initially, the bank has ten dollars to loan out, to invest, to do what have you with. Of course, just sitting there, the bank makes no profit. Right now, their balance sheet looks like this:


Since the bank has $10 in capital, the bank is worth about $10 all in all on the market; the liabilities and assets minus the capital. Now, to make money, banks take deposits and make loans. Let's say that Andrew deposits $90 into the bank, and is promised a 3% interest rate. Now the balance sheet looks like this:


For now, we'll ignore that interest rate; let's say this all happens on the same day, as the interest rate is largely unimportant for the purpose of this explanation. Now, the bank has $100 total in its vault, but if it just sat there, the bank would of course lose money. In a year, the bank would owe back that $90 plus the 3% rate if Andrew returned to withdraw his money. But then, someone else comes along, Scott, who wants to purchase a house. He needs $100 in order to do this. Bank A gives him a loan with a 6% interest rate:


So now, in a year, Scott will owe $106, and the bank owes Andrew $92.70. They would make a profit of about $3.30 after this timespan. This is how banks make money - loan out money at a high interest rate, and take depositor money and give it a lower interest rate.

Anyway, the housing crisis comes along. Suddenly Scott's house's value plummets 25%, down to only $75. Scott, falling on hard times himself, loses his job because of layoffs. He defaults on his loan, and the bank must foreclose and take the asset for itself. This creates a significant problem. Here's the balance sheet:


Now the bank owns a house that is worth only $75. If Andrew came back and wanted his money back from the bank, the bank would be unable to pay it, even after selling Scott's old house. The bank could thus be said to be worth about $75 + $10 - $90, or -$5.

This is obviously a bad thing. The bank is no longer solvent. It no longer has enough capital and assets to pay back the people who put money into it. This is exactly the situation that the banks have been battling; struggling to keep their capital and assets combined above their liabilities.

Obviously, the problem arises when Andrew comes to withdraw his money. The money is not actually all there; if the bank went out of business (and the FDIC did not exist), then Andrew would only be returned $85 of that $90 he initially put in, and the bank is now worth nothing and goes into bankruptcy.

The solution so far has been to give money to those banks in order to ensure that they can pay off the people who want to withdraw their own money from the banks. What the banks have been advocating is that the government uses tax money in order to purchase those homes from the bank, essentially. The homes have a market price, but clearly even if the government paid $75 to Bank A, Bank A still would not have enough to repay Andrew. So the banks have wanted essentially the highest possible price the government could pay. The problem is, though, that banks wish to avoid nationalization at all costs; this essentially means that the bank's "life" as a corporate citizen comes to an end.

Herein lies the problem. If the government gobbles up the assets of the bank, and takes over 50%, it effectively has the majority say in the direction of the company. It can veto things the company tries to do or propose and hammer through its own opinions and methods. Of course, this would probably be temporary; the government would almost certainly sell the company back to private hands once the coast is clear, so to speak.

Anyway, listen to the podcast here for plenty more great talk about what's actually going on.

Zero

Treasury bill interest rate dropped to or below zero. This is on the four-week treasury bill.

Essentially what this means is that investors are "lending" their money to the government and not expecting any kind of return on it. They give $1,000 and four weeks later they are given $1,000. Or maybe $999 if you believe the Wall Street Journal. Essentially the four week t-bill system is a giant mattress where occasionally a dollar bill falls out.

EDIT: Whoa, apparently YouTube is no longer blocked, so I can listen to whatever the hell I want to. Sweet.

Recession?

Yep, it's official. The United States economy, as of yesterday, was declared to be in a recession. Party, anyone?

At least we aren't Zimbabwe. As of two weeks ago, the inflation rate of the Zimbabwe dollar has breached sextillion percent (1,000,000,000,000,000,000,000) and the exchange rate with the US Dollar was thirteen quadrillion (13,000,000,000,000,000). Essentially this means if you wanted to buy a $0.25 USD gumball with Zimbabwe money, you would need 3,250,000,000,000,000 ZWR. Yup. So essentially what this does is drive people to immediately exchange their money for something that holds more value (USD or something more local), since the inflation rate causes the ZWR to lose 50% of its value daily. If you're paid $10 for something today, then it's worth $5 tomorrow. In a week it's worth less than eight cents.

So maybe that party is due after all... at least for the Zimbabweans. Better to spend the money right now rather than wait for it to melt in your pocket!

What is Money?

This week on Planet Money, Alex Blumberg and company investigate exactly that question: What is money? Monday's podcast was especially illuminating, featuring economist, author, and Harvard professor Niall Ferguson explaining what money is.

The crux of his argument isn't that money is paper and coins, bank notes and IOUs. Money is a symbol, whether tangible or intangible, that crystallizes a relationship between loaner and debtor. Money is confidence in other people and society as a whole. It has exactly the value that society assigns to it and no more or no less. If tomorrow everyone in the world decided that all money was worthless, it would be worth exactly zero.

One of Ferguson's anecdotes was of an epiphany he had while studying the past of money. He found a clay tablet that had written on it a promise to pay a certain amount of wheat to whomever possessed it. He realized that this was one of the first instances of money; an otherwise worthless object that, because of what could be considered a "confidence trick," was worth so many kilos of a commodity.
