Yield curve can predict future growth in output

Hi Guys,

Can anyone kindly give me a dumbed down explanation as to why the yield spread between 10-year T-bonds and 3-month T-bills narrow or become negative prior to recessions?

The CFA book explain it is due to 1) future short-term rates are expected to fall.

I don’t understand the logic here. If T-bonds are 2% and T-bills are 0.05%; then if the rate on T-bills declined to 0.04%, the yield spread would increase from 1.95% to 1.96%?

if T-Bills yield declines to 0.04% like you say - do you think T-Bonds will stay at 2%? Given t-bills are shorter term instruments - T-Bonds will decline MORE …

2 - 0.05 = 1.95% prior to recession

possibly 1.9 - 0.04 = 1.86%

so the yield spread declines …

Since Treasury spread (10 year bond rate - 3month T-bill rate) is a leading indicator and calculates for a probability of a recession in US.

So for example the Treasury spread for September 2015 is 2.07% which is 207bps difference between the 10year bond and 3month t-bill: 10yr: 2.09% while 3 month t-bill: 0.02%.

So when do you expect those spreads to narrow? When you exepct short-term rates to decline (The Fed will reduce interest rates, QE1,QE2,QE3,…) So 10year bond rate falls to 1% and the yield curve get inverted and those spreads can turn to zero or negative.

In 203-2004 the spread was 3% = 300 bps (economic expansion) while 2009 was -1bps = -100 bps. (economic recession)

An inverted yield curve is a predictor of an oncoming recession.

the answer is a bit wierd, but obviously the fed normally pumps money in at the short end so you expect short rates to falll later on.

I’ll give an explanation in my own words.

Once you reach a certain interest rate on simple accounts like a savings account, people delay long term investments, because they’re earning so much without any trouble. I remember when my savings account earned me over 5% before the crisis - I was running a small business at the time, and it rose the hurdle rate for any acquisitions I was considering.

This process creates an inversion. Less investment at the longer end of the yield curve results in less supply of high duration assets (lowering interest rate there) and the short end is driven more by central bank policy than necessarily supply and demand.

This change in investment and activity is a part of what leads to a slowdown in the economy.

Very helpful everyone, thank you!
