The U.S. sells Treasury bills (less than a year long holding), Treasury notes (mature in fewer than ten years), and Treasury bonds (mature at 20 or 30 years). Through these different debt vehicles, the U.S. controls the money supply, which affects the economy...inflation, specifically. In addition to taxes, these securities generate some income for the U.S. Treasury.
All of these U.S. Treasury securities are tracked on the Treasury index: an index based on what those securities are being auctioned off for. That means it’s basically an index summarizing the daily yield curve, which is what you can expect to get back in returns on U.S. Government debt securities. Long-term Treasuries with high yields indicate that investors have a good feeling about the economic future.
Banks use the Treasury index all of the time as a baseline for writing mortgage notes (the document you sign that makes you officially obligated to pay your mortgage when you buy a house) and interest rates for other types of loans. Interest rates and the U.S. debt securities are tied together. When Treasury yields rise, interest rates usually rise as well.

Finance: What are Treasury Bills?15 Views
finance a la shmoop. what are Treasury bills? well the US government is a
financial pig. it borrows money all the time [pig crosses screen]
snort snort. well somebody's gotta buy vibrating back massagers for all those
senators. tea bills are just one way in which the government raises cash for
itself to you know buy things. the deal works like this.
investors write a check to the US 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 ish period of time .while tea bills are like that
they're typically short in duration and they sell at a discount to par like a
zero coupon bond .meaning that an investor might pay nine hundred eighty [zero coupon bonds explained]
two dollars for a thousand dollar par bond which comes due in six months. the
investor for loaning the government her nine hundred eighty two dollars in cash
for six months gets paid eighteen 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
investment return is eighteen bucks on a grand for six months. that implies an
annualized interest rate on the money ie over twelve months of what? mm-hmm we're [equation]
testing you here a little bit just seeing if you're awake. well if an
investor makes eighteen bucks in six months which is half a year if you
doubled the six months to be twelve months or a full year well you could
also double the eighteen bucks to be thirty-six bucks and yeah that's it.
notionally had the government rented that grand for a year it would have paid
thirty-six dollars for the privilege or three point six percent interest
annualized. thirty-six bucks over a grand. that's how we got there but it's not
quite accurate why? because the investor didn't put in a full grand ,they will
have put in less. well in this example they invested nine hundred eighty two
dollars and they got back eighteen bucks for six months of doing a whole lot of [piggy bank called "U.S gov."]
nothing. watching the clock and hoping the US
government wouldn't go bankrupt during that time period. so the interest rate of
return to the investor? well you take 18 bucks and divide it by 982 and you get
about 1.8 3% annualize it and you get a skosh more than 3.6 percent ie something
more like three point six six percent or so .small change but on big numbers that
adds up 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. what do you think? [pig walks on back legs through a store carrying a basket]
