I woke up this morning wanting to answer one question more than any other. Why is the yield on a 2-year bond (4.37%) higher than the 10-year yield of 4.35%? 
After some research, I have to admit I’m still a little lost. Understanding how our economy runs is not my strong suit (you’d be better off reading Chris’s posts). But I’ll take a stab at this.
Economists call what’s happening in the bond market an inverted yield curve2. The fact that we are seeing one now is cause for concern. From Investopedia:
Historically, inversions of the yield curve have preceded many of the U.S. recessions. Due to this historical correlation, the yield curve is often seen as an accurate forecast of the turning points of the business cycle. A recent example is when the U.S. Treasury yield curve inverted in 2000 just before the U.S. equity markets collapsed. An inverse yield curve predicts lower interest rates in the future as longer-term bonds are being demanded, sending the yields down.
That’s pretty scary stuff. If you’re looking for a reason to remain bullish, a Morning Star Bond Report3 had this to say:
Some economists continue to eye the yield curve as a daily economic indicator. Others question its utility, saying special factors, such as the government shifting issuance to shorter maturities, have distorted the curve’s telling powers.
So I’m not sure if I should be scared or not, but we still don’t know WHY the curve got inverted in the first place. The “why” in all of this would seem to be important. John Rutledge tries to sum things up this way (emphasis mine)4:
1. An inverted yield curve is not the end of the world. The last 4 recessions have all been preceded by inverted yield curves, but that does not mean that an inverted yield curve always implies a recession.
2. The important thing is why the yield curve is inverted. If the yield curve is inverted because the Fed has just forced a sharp increase in short rates (like 1980-81) you may have a problem. If it inverted because long rates have been easing lower to reflect moderating inflation worries (like today) it might be fine.
3. The anchor on inflation today is Chinese and Indian wage and prices. It makes sense for investors to expect low inflation in future years.
4. Either way, the condition is likely to be temporary because inflation is not likely to fall forever. It could be resolved next year by the Fed backing away from tightening short rates to keep bank reserves growing. Or it could be resolved by a major bankruptcy (GM? Ford?) which would push the Fed away from tightening.
5. Implication: in a world where the Fed is targeting prices, it is not appropriate to view them as an exogenous driver of the economy. Their behavior will adapt to outside influences on prices, e.g., oil prices, price and wage differentials, and technology changes.
6. The economy is growing, inflation is low, and profits are increasing at double digit rates. This is a great time to buy stocks. If people get spooked by the inverted yield curve and prices fall, buy more equities.
Ok, so our yield curve is inverted because long-term rates have been dropping (or in reality lagging behind short-term rates as the Fed hikes interest rates) “to reflect moderating inflation worries”. We’d only have to worry if the inversion was due to short-term rates increasing. Ahhhh.
I liked Katie Benner’s take over at CNN Money. Benner writes that a gradually flattening curve isn’t worrisome in itself, which is what we have now with the difference between 2-year and 10-year rates tightening by 10-15 basis points per month. Benner quotes Anthony Crescenzi who says, “It is when the pace becomes much faster than 15 basis points a month that investors should start to worry.” 
Hopefully this will help you understand what those folks on the TV are talking about. I’m interested in hear your thoughts.
