Treasury Yield Spreads

in treasury •  2 years ago 

The Treasury yield spread is a useful indicator of a recession.
Usually, there is a difference between 10-year and 2-year bonds, or 3 months of 10-year bonds, but there is no exact theoretical basis yet.

Powell has a different view of the yield curve inversion than the general idea.
The yield curve that Powell takes consideration is the 3-month forward rate 18 months later, which is obtained by inversely calculating the interest rate traded in the market. (18m/3m - 3m)
The inverse calculation is based on the assumption that there is no risk-free arbitrage.

This rate is usually expressed as 18m/3m and can be obtained as follows.

Here, S1 is the 21-month interest rate as of now (spot) and S2 is the 18-month interest rate seen as of now (spot).
n1 is 21 months or 1.75 years, n2 is 18 months or 1.5 years. n1-n2=0.25.

The problem is that there is no 21-month spot rate and 18-month spot rate in the Fed data.
If you use the 1-year and 2-year rates to obtain a linear relationship, you can get more or less similar values.
If the 1-year interest rate is a and the 2-year interest rate is b, the 1.5-year interest rate uses the average (a+b)/2 of the two as S1.

The interest rate for 1.75 years is (a+3*b)/4 to find S2.
After going through this process and putting it into the above formula, you can get a value close to 18m/3m. The yield curve divergence that Powell likes is 18m/3m - 3m, so plugging it into the equation and doing the math gives us the following figure:

It is highly recommend not to take this result as a serious investment action basement.
Even with small asumption of a few variables, the result could make very theoritical data that doesn't reflect high fluctuated market and policy changes. It is required to consider other index that make this more reliable.
