The yield curve is one of the most and best used instruments in the global macro investors arsenal. The yield curve is usually thought of as a bond traders tool but good global macro trader know better. You can use the yield curve to trade bonds, stocks, currencies, and really just about anything that affects the economy, heck you can even use to for refinancing your home.
While there are may types of yield curves the most commonly used and most applicable is that of the Treasury yield curve. All you need to do to make a yield curve is to obtain the yield on different Treasury maturities. Get the ninety day, two year, five year, ten year, and the thirty year yields and you will be able to plot them out and see the shape and levels of the yield curve.
So how do you apply the yield curve to your trading? Well there are a few main rules of thumb. An upwards sloping yield curve is typically bullish for the economy and stocks, whereas a downwards sloping or inverted yield curve is typically bullish for bonds.
You may be asking yourself why this is. The reasons are actually fairly simple and straightforward. If the curve is steep, meaning the short term rates are low and the long term rates are high it means that banks are lending as they are able to borrow short term from the Fed and charge long term rates to their customers. Obviously when business is good for the banks, they will be lending as much as they can. This in turn spurs new business spending as money is available.
If the curve is inverted however business is usually about to slow down, rates will be lowered, and bonds will climb. This is because with the incentive of the banks to lend now gone they will throttle back and the spigots of available money run dry. In turn this forces the Fed to lower short term rates, the Fed Fund rate, in order to spur business growth once again. When they lower rates bonds inevitably go up.
Think of bonds and interest rates as a teeter totter where yields are on one side and bonds are on the other. If bonds go down, rates go up. If rates go down, bonds are going up. In a regular inflationary environment this is always the case unless there is a severe credit quality issue.
So anytime that you see either of these events happen the global macro investor can start to look for an entry point to either buy or to sell bonds and stocks. If the curve is inverted then you will likely want to start buying bonds and selling stocks as the act of lowering rates will cause bonds to go up. After bonds have gone up and it looks like the Fed is done lowering rates it is worthwhile to look at stocks as the next beneficiary of the rate cuts as businesses can now borrow cheaper and therefore expand faster.
Of course as with all things in the market nothing works every time. In fact the quote history never repeats itself, but it often rhymes is a very appropriate statement. Used along with proper risk controls the yield curve can become one of the global macro investors best timing tools and economic gauges.
