Is it normal that US Treasury bills(0.07%) yield smaller than interest rate(0.25%)?
Maybe someone will have more details, but a couple of things come to mind immediately: Im not sure if its normal/sensical/healthy, and that is kind of opinion based. But there is a reason for it. Certain rules and regulations passed recently are causing companies or institutions to shift to bonds from cash. Fidelity, for example, is completely converting its $100 billion dollar cash fund to short term bills. Its estimated that over $2 trillion that is now in cash may be converted to bills, and that will obviously put upward preasure on the price of them. The treasury is trying to issue more short term debt to balance out the demand. read more here: http://www.wsj.com/articles/money-funds-clamor-for-short-term-treasurys-1445300813 I have been charting the CPI reported inflation rate vs . the yeald on the 10-year T-note. Usually, the two like to keep pace with each other. Sometimes the T-note is a bit higher than the inflation rate, sometimes the inflation rate is a bit higher than the T-note yeald. One does not appear to follow the other, but (until recently) the two do not diverge from each other by much.  But all that changed recently and I am without an explanation as to why. Inflation dropped to zero (or a bit negative) yet the yeald on the 10-year T-note seemed to seek 2%.  Edit: If you give this response a downvote then please be kind enough to explain why in a comment.  Edit-2: CPI and 10-year T-note are what I have tracked, and continue to track. If you do not like my answer then provide a better one, yourself.
These are yields for the government bonds. EuroZone interest rates are much lower (10 times lower, in fact) than the UK (GBP zone) interest rates. The rates are set by the central banks. You need to read up on how QE works. Banks are not reinvesting deposits at the Fed in Equities. They are earning interest and sitting there, hence why the velocity of any money supply measure is far below where it used to be. The only reason I can think of would be if you were convinced that you couldn't hold on to your money. Treasury Bonds are often viewed as very safe investments, and often used in some situations where cash isn't appropriate.. Also, they typically have a somewhat patriotic theme, helping your country to grow. In addition, many people don't really pay attention to the rate of the bonds, but are just investing in them. The more people investing in them, the lower the yields become. But the bottom line is, I would invest in a savings account any day over a negative interest rate... And it looks like I'm in good company as well, a quick study of reports seems to indicate that these are a very bad investment... "The simple answer for the so-called 'Rule of X' would be found by: In your case: Update:  If you want an approximation closer to the nominal ""Rule of 72"" value, use this equation that incorporates a better approximation for the natural log. The ""Rule of 72"" fits this for an interest rate of 7.79% for a growth multiple of 2: The rule of 72 comes from by approximating the natural logarithms as such: The 2 is the multiple of growth. The rate r here is not in percent, so to change to percent (say, R) you have to multiply by 100: The number 72 is often used because it is easier to divide evenly than 69.3 and is a better fit approximation for the natural log and common interest rates.  If you need more, you can find all this on Wikipedia: https://en.wikipedia.org/wiki/Rule_of_72#Derivation" "All of the other answers here are accurate, but (I think) are missing the point as to the question, which rests on how Bonds work in the first place. The bond specifies a payback AMOUNT and DATE. Let's say it is $10,000 and one year from today. If you buy that today for $9900, your yield will be 1%. If you buy it today for $11,000, your yield will be less than 0% (please don't make me do the math - it's just under negative 1%). You might be willing to pay that 1% (rather than receive 1%) for the certainty that you will definitely get your money back. The combined actions of all the people who may be willing to pay a little more or a little less for the safety of a US Treasury Bond is what people call ""the Market.""  Market forces (generally, investor confidence) will drive the price up and down, which affects the yield. All the other stuff - coupons and inflation and whatnot - all of that only makes sense if you understand that you aren't buying a rate of return, you are buying a payback amount and date." yield on a Treasury bond increases This primarily happens when the government increases interest rates or there is too much money floating around and the government wants to suck out money from the economy, this is the first step not the other way around. The most recent case was Fed buying up bonds and hence releasing money in to the economy so companies and people start investing to push the economy on the growth path.  Banks normally base their interest rates on the Treasury bonds, which they use as a reference rate because of the probability of 0 default. As mortgage is a long term investment, so they follow the long duration bonds issued by the Fed. They than put a premium on the money lent out for taking that extra risk. So when the governments are trying to suck out money, there is a dearth of free flowing money and hence you pay more premium to borrow because supply is less demand is more, demand will eventually decrease but not in the short run. Why do banks increase the rates they loan money at when people sell bonds? Not people per se, but primarily the central bank in a country i.e. Fed in US. Interest is calculated daily. Doing the math: Between 6-17 and 7-25 are 38 days, 200.29 / 38 = 5.27 interest per day. Between 7-25 and 8-17 are 23 days. 120.02 / 23 = 5.22 interest per day. The minimal difference is because the principal has already gone down a little bit. So you should expect ~5.20 x number of days for the next interest number coming up; slowly decreasing as the remaining principal debt decreases. Note that this is equivalent of an annual interest rate of over 20 %, which is beyond acceptable. In the current economy, this is ridiculously high. I recommend trying to get a refinancing with another provider; you should be able to get it for a third of that. As no one has mentioned them I will...  The US  Treasury issues at least two forms of bonds that tend to always pay some interest even when prevailing rates are zero or negative.  The two that I know of are TIPS and I series bonds. Below are links to the descriptions of these bonds: http://www.treasurydirect.gov/indiv/research/indepth/tips/res_tips.htm http://www.treasurydirect.gov/indiv/research/indepth/ibonds/res_ibonds.htm "You may be thinking about this the wrong way. The yield (Return) on your investment is effectively the market price paid to the investor for the amount of risk assumed for participating. Looking at the last few years, many including myself would have given their left arm for a so-called ""meager return"" instead of the devastation visited on our portfolios.  In essence, higher return almost always (arguably always) comes at the cost of increased risk.  You just have to decide your risk profile and investment goals.  For example, which of the following scenarios would you prefer? Investment Option A  Treasuries, CD's Worst Case: 1% gain Best Case 5% gain   Investment option B  Equities/Commodities Worst Case: 25% loss Best Case: 40% gain" "1.65% is the annualized interest rate. If it is pail semi-annually, you'd get 8.23 every 6 months.   And yes, if the YC is upward sloping, it means that 30 years t-bills pay higher interest. Thats a premium they pay for having your money locked in for a long time. It makes sense if you consider that they'd pay you that rate (say 2%) for the next 30 years. If for some reason interest rates in 25 years from now are like 15-20% (like they were 25 years ago) and inflation around the same rate, you'd still only be making 2%, on top of bleeding purchasing power of your initial investment. That's why long-term bonds require a premium.   That being said, sometimes you get an ""inverted yield curve"", where yield's fall with the longer maturities. Look that up." It depends how much risk you're prepared to accept. The short-term risk-free rate of return at present is something in the vicinity of 0.1% (three month US treasuries are currently yielding 0.08%), so anything paying a higher rate on money that's accessible quickly will involve some degree of risk -- the higher the rate then the higher the risk. weird holdover from the bad old days when you had to do arithmetic by hand I would guess.  Stocks used to trade in 1/8ths, so bonds trading in even smaller increments makes sense.  Also (and I am unsure if this is still true) U.S. bonds trade on a 360 day year (or used to anyway) for the same reason... 360 divides well into months and quarters (for easier math) whereas 365 is considerably harder.  Most of the world now trades in decimals and 365/365 years so I am unsure why the U.S. doesn't.  Institutional inertia I would guess. Generically, interest rates being charged are driven in large part by the central bank's rate and competition tends to keep similar loans priced fairly close to each other. Interest rates being paid are driven by what's needed to get folks to lend you their money (deposit in bank, purchase bonds) so it's again related. There certainly isn't very direct coupling, but in general interest rates of all sorts do tend to swing (very) roughly in the same direction at (very) roughly the same time... so the concept that interest rates of all types are rising or falling at any given moment is a simplification but not wholly unreasonable. If you want to know which interest rates a particular person is citing to back up their claim you really need to ask them. There are a few other factors possible here: Taxes - Something you don't mention is what are the tax rates on each of those choices.  If the 4% gain is taxed at 33% while the 3% government bond is taxed at 0% then it may well make more sense to have the government bond that makes more money after taxes. Potential changes in rates - Could that 4% rate change at any time?  Yield curves are an idea here to consider where at times they can become inverted where short-term bonds yield more than long-term bonds due to expectations about rates.  Some banks may advertise a special rate for a limited time to try to get more deposits and then change the rate later.  Beware the fine print. Could the bond have some kind of extra feature on it?  For example, in the US there are bonds known as TIPS that while the interest rate may be low, there is a principal adjustment that comes as part of the inflation adjustment that is part how the security is structured. I concur with the answers above - the difference is about the risk. But in this particular case I find the interest level implausible. 11% interest on deposits in USD seems very speculative and unsustainable. You can't guarantee such return on investment unless you engage in drug trade or some other illegal activity. Or it is a Ponzi scheme. So I would suspect that the bank is having liquidity problems. Which bank is it, by the way? We had a similar case in Bulgaria with one bank offering abnormal interest on deposits in EUR and USD. It went bust - the small depositors were rescued by the local version of FDIC but the large ones were destroyed.
