Understand investment basics - bonds yield, bonds investment and bonds price. Know China influence on bond demand
Although bonds investment is characterized by its face value, coupon rate, maturity and issuer, one very important investment basics that savvy investors know is called bonds yield. Yield is the rate of return you get on bonds. When price goes up, yield goes down, and vice versa. When interest rates rise, the price of bonds in the market falls; and vice versa.
Bonds yield or interest is stable but bonds prices can fluctuate a lot... bonds investment can be a risky instrument
We need to elaborate a bit about the bonds prices. The bonds prices are merely affected by demand and supply. Please do not think that bonds prices will change after FOMC meeting. Federal Reserve can only change fed fund interest rate (short yield).
Theoretically bond price is the net present value of the bond interest rate (yield). In reality, the bond sales are a bidding operation. The lower interest rate that completes the bond sales lot.
Bonds are generally viewed as safer investments than equities, but this perception is only partially correct. Treasury bonds do suffer from less day-to-day volatility than stocks, and bonds interest payments are generally higher than dividend payments. Treasury bonds are liquid, though not nearly as easy as it is to sell stocks. The bonds prices can be very volatile on short term trading. Why?
Bonds, a general understanding, will decrease in value when prevailing interest rate rises. When the market's interest rates rise, then the market price for bonds will fall, reflecting investors' improved ability to get a good interest rate for their money elsewhere. This is predominantly an opportunity costs concept of holding bonds.
It is because you can always purchase a newly issued bond that features the newly higher interest rate. This drop in the bond's market price does not affect the interest payments to the bondholder at all. Therefore long-term investors need not worry about price swings in their bonds if they hold to maturities. However, price changes in a bond immediately impacts your current holding particularly if there is any chance you need to sell your bonds and "cash out" for some reasons.
On the other hand, bonds' market prices would increase if the prevailing interest rate were to drop, as it did in 2008. You can cash in a big profit on selling your on hand holding bonds not to wait for their maturities. You can think of this in the following way: If you own an asset worth $100 that gives you a 6.0% interest annually for 10 years, will you ask for a HIGHER price if someone wants to exchange you with an asset worth $100 but gives you only 4.5% interest annually? Definitely yes!
In other words, your current bond holding bearing 6% interest worth more than the new issue bearing only 4.5% interest. This means you have a good investment having a capital appreciation because you correctly predict the interest rate to drop when you buy the 6% interest debt in the first place!
Real demand & supply determine the bonds yield
The next question is: what are the factors that drives down the yield from, say from 6.0% to 4.5% and hence raise the bonds price? Remember that bond sales are bidding operations?
You may think about this way: There are many investors in bonds. These investors are preparing for their own bids. That is, investors are figuring out the lowest yield or return that they are prepared to accept bonds in exchange for his US dollar cash on hand...
Look at bonds price from an opportunity costs concept
In making this decision to come up with 4.5%, they will compare investment opportunities for risks and returns. For instance,
- Equities are trading at price earning ratio of 20. This means that the yield or return is 4% (1/25) if the growth and dividend yield is not considered. The equities are currently choppy not having an obvious uptrend, the investment risks is much higher because the company may suddenly go bankrupt like Lehman Brothers. The future earnings will be deteriorating. Money is flight from quality and move investing bonds.
- Residential properties are having a 4% rental yield (net of tax and expenses) but tenants may move out being unemployed. The mortgage interest is as high as 5% and the vacancy rate is more than 7%, the property price is expected to drop further. Property investment is not a good choice.
- Saving interest is shamefully negligible. Inflation will eat up purchasing power of cash. Yet we must maintain enough cash as safety net since unemployment can be as high as 9%. We cannot invest all cash into bonds...
- Gold price is already $900, can we get a 4.5% increase for 10 years. Gold bears no interest, is capital gain likely to surpass bonds yield?
We see that all these assets are competing with each other on the limited cash – opportunity costs concept.
Demand and supply are driven by different considerations of investors.
On the supply side, we all know that US government is the sole supplier of new issue of US treasury. Yet all the existing bonds holders can also supply by selling in the open market. On the demand side, there are different types of investors:
- China and Japan, the biggest exporter to US, has been the biggest buyer of US Treasury Bonds. China seems to reduce its purchase of new bonds issue since 2005 (due to many reasons politically and economically).
Below are the bonds yield extracted from Yahoo Finance for Feb 2, 2009.
| Maturity | Yield | Last Week | Last Month |
| 3 Month | 0.22 | 0.07 | 0.05 |
| 6 Month | 0.33 | 0.30 | 0.26 |
| 2 Year | 0.88 | 0.83 | 0.83 |
| 3 Year | 1.25 | 1.20 | 1.08 |
| 5 Year | 1.75 | 1.65 | 1.66 |
| 10 Year | 2.72 | 2.64 | 2.38 |
| 30 Year | 3.47 | 3.37 | 2.80 |
- The low bonds yield at 2008 year end was mostly due to repatriations of fund by US corporations from oversea affiliates at year end (that is, sell foreign assets to cope with credit crunch); and, flight from quality in equity investing. The corporations temporarily parked fund in the bonds market. The 3-month T-bills were having virtually zero interest and 10-year T-notes yielded only 2.38%.
- Remember Fed can only change the short yield, the long yield is determined by demand (fund inflow into or outflow from the bonds market) and supply (incremental supply from US government on new issue and sales from bondholders).
One last point to note is that China can drag up the US treasury yield a lot if China disposes of its holdings on hand. It seems that this is not happening as this is lose-lose scenario. The huge amount of bonds on hand with China would suffer at a revaluation loss (or actual loss). US would expect bonds demand to reduce, bonds price to drop, long yield to rise and mortgage rate to raise deterring consumer spending; and subsequently US government obliged to pay a higher interest to attract potential investors.
