Understanding the National Debt and Budget Deficit

Good morning Hank, it's Tuesday. So, one of the biggest issues in global politics these days

is government debt and deficits, which is a particularly big deal in the United States

because of the Presidential campaign and also because of the looming fiscal cliff.

And Hank, as you'll no doubt remember, I received a bronze medal in economics

at the 1994 Alabama State Academic Decathlon, meaning that in 1994,

I was the third best seventeen-year-old economist among all C students in the state of Alabama,

so not to brag or anything, but I'm pretty qualified to explain this stuff.

Okay, so first we have to separate the ideas of debt and deficit.

Debt is the total amount of our outstanding liabilities.

Deficit , or occasionally surplus, is the difference between what the government spends and what it takes in.

Right, so in the United States, our current national debt is around 16 trillion dollars,

which sounds like a lot of money, and it is.

But let's break this down.

The largest single holder of U.S. government debt is actually the Federal Government itself

because trust funds like Social Security buy government bons and so the interest goes from the U.S. government to a different part of the U.S.government,

which is not borrowing as we usually imagine it.

So if you take away that money, you're left with about 11 trillion dollars, which is still a fair bit of cash.

Who owns that debt?

China, you probably guessed, but in fact, no. The plurality of that debt is actually owned by us.

Us being American individuals and institutions.

China owns about 8% of our debt, Japan 7% and the UK, 1%.

But it's important to note that the US also owns foreign debt, including about 235 billion dollars

of sovereign debt in China and Hong Kong.

Altogether, for every one dollar of US debt that's owned by a foreign country,

we own about 89 cents of foreign debt.

So you can't really think of government debt the same way you'd think about, like, a family

owing money to a credit card company because in that situation, the family owes money to someone else.

But in the case of US government debt, we mostly, indirectly or directly, owe money to ourselves.

So our national debt is a very large number, but at least at the moment, it is not a very large problem.

Like in 2011, we paid about 3% total interest on our debt. In 2012, it will be even less because our debt

is incredibly cheap right now.

I mean, Hank, in some ways, it is literally cheaper than free. Right now, the yield on a one year treasury bon

is 0.17%. Okay, two very important things to note about the debt:

First, China can't, like, call in our debt on a day of its choosing.

If I buy a $100, one year treasury bon today, I'm going to get that $100 back, along with my 17 cents in interest

in one year. I can't call after a month and be like, "Give me my money back!"

So despite what you hear from a lot of political commentators, that is not really a risk

to the US economy. Secondly, you may have heard people say, "The government should be run

like a business. It should never spend more than it takes in."

Yeah, no, that is not how businesses are run. Like, say that tomorrow, I invent a Marty McFly

hovercraft skateboard. In that situation, I wouldn't wait twenty years until I've sold enough DFTBA posters

to build my Marty McFly hoverboard factory. I would just borrow the money and build the factory immediately

so I could start selling hoverboards and swim in a sea of hundred dollar bills.

Actually, I would not swim in a sea of hundred dollar bills. I would hoverboard over that sea.

Businesses spend more than they bring in all the time, as well they should

and almost all economists agree that governments are similar. There are times when they need

to run deficits. For instance, during a recession, government revenue goes down

because wages stagnate and unemployment goes up. But government expenditures have to go up,

like on unemployment benefits, for instance. So just to be clear, deficits are not inherently evil

and our current debt, while it is very large, does not pose a threat to the American economy because we can

pay it back with relative ease. I mean, it's not going to be free, but it's going to be like 2% of GDP.

We've done it before!

However, there is a huge future risk to us, because what if our debt stopped being cheap?

What if people stopped believing that the US is the safest place to put their money and they start to

buy bonds in, I don't know, like Brazil or China or Germany?

Well, that would be very bad because most years, we run a budget deficit and so we would need to keep

borrowing money at these higher interest rates, which would necessitate more deficits,

and therefore more borrowing at progressively higher interest rates.

And then we'd have to cut spending, which would slow growth and raise taxes,

which would slow growth more, and then Greece.

Except this might actually be much worse for us than it's been for Greece because the US enjoys all kinds of

benefits from having the world's most trusted currency.

Like, Hank, believe it or not, most US paper currency actually circulates outside the US

and that's very helpful for us in terms of exchange rates and keeping our debt cheap

and if we lost that, it would be devastating because we would just be a regular country again.

Okay, so the federal deficit in 2011 was about 1.3 trillion. It'll be down a little bit this year to about a trillion.

It'll be down further in 2013, no matter who is president, to about 900 billion.

But most people think that number needs to continue to come down, or at some point, we are going to risk

the spiraling higher interest rates.

So there are two ways of doing this. This first is to print more money, like, oh, we need a hundred billion dollars

to close the deficit? Look, I just made a hundred billion dollars using a printing press!

That sounds like a fine idea, except that it will lead to inflation. Now a lot of people in comments will be saying

that we should just return to the gold standard, which I think is a very bad idea, for the reasons I explain

in the dooblydoo. However:

In the broadest sense, our currency is already pegged to goods and services

because if the amount of money in the world doubled tomorrow, the amount of stuff wouldn't,

so you can imagine what would happen to the cost of everything: It would double.

The second, and better, way to cut the deficit is to close the gap between what we take in

and what we spend, and in times of economic expansion, this is actually quite easy

because the tax base grows and the amount of money people make goes up, so they pay more taxes,

so we can just have surpluses, as we did in the 1990s.

But during slow recoveries, like the one we have right now, it is much more complicated.

So, like, both President Obama and Governor Romney favored unspecified spending cuts,

Governor Romney also favors a tax cut of 20% across the board,

whereas President Obama thinks that we should increase taxes by rolling back the Bush era tax cut

on income over $250,000. Neither of these plans is likely to eliminate the deficit,

although, again, the deficit doesn't necessarily need to be eliminated.

And no matter what political rhetoric you hear, neither of these plans is terribly radical either.

President Obama wants to put the top marginal income tax rate at 39%.

It was over 50% every year from 1945 until 1986.

Mitt Romney wants to cut that tax rate to 28.5%, which is where it was in 1989.

We can argue thoughtfully about what our policy position should be, but amid all the rhetoric and

decontextualized statistics, I just want to underscore that while deficit reduction is important,

it is not a crisis. The whole idea here is to keep it from becoming a crisis and one of the best ways to do that

is to understand the problem without yelling about it, discuss things honestly without assuming

that the people who disagree with you hate America.

Hank, I'll see you on Friday.

I'm still working on my punishment, sorry.
