Treasury Bill

  

Categories: Bonds

The U.S. government is a financial pig. It borrows money alllll the time. Snort snort.

Somebody's gotta buy vibrating back massagers for all those senators' mistresses, right? T-Bills are just one way in which the government raises cash for itself to, uh…buy things.

How does they work? Investors write a check to the U.S. government, taking their hard-earned cash and giving it to Uncle Sam, who in return gives them a piece of paper promising to pay them back in a short period of time. So yeah...Treasury Bills are typically short in duration. And they sell at a discount to par, like a zero coupon bond. Meaning that an investor might pay $982 for a thousand dollar par bond which comes due in 6 months. The investor, for loaning the government her $982 in cash for 6 months, gets paid 18 dollars in rent on that money. There are no interest payments made along the way, as there would be in a traditional bond investment, which typically pays interest twice a year. In this case, the investor is just buying a grand at a discount. Simple.

And note that, in this case, the return is 18 bucks on a grand for 6 months. That implies an annualized interest rate on the money, i.e. over 12 months of…what? Well, our investor makes 18 bucks in 6 months, which is half a year, so double that is 36 bucks for a full year. Notionally, had the government rented that grand for a year, it would have paid 36 dollars for the privilege…or 3.6% annualized interest. That's 36 over a grand. But it's not quite accurate, because the investor didn’t put in a full grand...they put in less.

In this example, they invested 982 and got back 18 bucks for 6 months of doing a whole lot of nothing, other than watching the clock and hoping the U.S. government wouldn’t go bankrupt during that time period. So the interest rate of return to the investor? You take 18 bucks and divide it by 982, and you get about 1.83%. Annualize it, and you get a skosh more than 3.6%, i.e. something more like 3.66%.

Small change, but big numbers. And now, with investor money, the government is free to do all its pork spending. Maybe a nice, new sty for the Speaker of the House. Oink.

00:28

and giving it to Uncle Sam who in return gives them a piece of paper promising to

00:34

pay them back in a short ish period of time .while tea bills are like that

00:38

they're typically short in duration and they sell at a discount to par like a

00:43

zero coupon bond .meaning that an investor might pay nine hundred eighty [zero coupon bonds explained]

00:49

two dollars for a thousand dollar par bond which comes due in six months. the

00:54

investor for loaning the government her nine hundred eighty two dollars in cash

00:58

for six months gets paid eighteen dollars in rent on that money. there are

01:03

no interest payments made along the way as there would be in a traditional bond

01:07

investment which typically pays interest twice a year. in this case the investor

01:12

is just buying a grand at a discount. simple .and note that in this case the

01:16

investment return is eighteen bucks on a grand for six months. that implies an

01:21

annualized interest rate on the money ie over twelve months of what? mm-hmm we're [equation]

01:29

testing you here a little bit just seeing if you're awake. well if an

01:32

investor makes eighteen bucks in six months which is half a year if you

01:35

doubled the six months to be twelve months or a full year well you could

01:39

also double the eighteen bucks to be thirty-six bucks and yeah that's it.

01:43

notionally had the government rented that grand for a year it would have paid

01:48

thirty-six dollars for the privilege or three point six percent interest

01:52

annualized. thirty-six bucks over a grand. that's how we got there but it's not

01:58

quite accurate why? because the investor didn't put in a full grand ,they will

02:02

have put in less. well in this example they invested nine hundred eighty two

02:07

dollars and they got back eighteen bucks for six months of doing a whole lot of [piggy bank called "U.S gov."]

02:12

nothing. watching the clock and hoping the US

02:14

government wouldn't go bankrupt during that time period. so the interest rate of

02:18

return to the investor? well you take 18 bucks and divide it by 982 and you get

02:24

about 1.8 3% annualize it and you get a skosh more than 3.6 percent ie something

02:31

more like three point six six percent or so .small change but on big numbers that

02:36

adds up and now with investor money the government is free to do all its pork

02:40

spending. maybe a nice new sty for the Speaker of the House. what do you think? [pig walks on back legs through a store carrying a basket]
