ACM Term Premium

pyacm

Implementation of "Pricing the Term Structure with Linear Regressions" from Adrian, Crump and Moench (2013).

The NominalACM class prices the time series and cross-section of the term structure of interest rates using a three-step linear regression approach. Computations are fast, even with a large number of pricing factors. The object carries all the relevant variables as atributes:

• The yield curve itself
• The excess returns from the synthetic zero coupon bonds
• The principal components of the curve used as princing factors
• Risk premium parameter estimates
• Yields fitted by the model
• Risk-neutral yields
• Term premium
• Historical in-sample expected returns
• Expected return loadings

Instalation

pip install pyacm

Usage

from pyacm import NominalACM

acm = NominalACM(
    curve=yield_curve,
    n_factors=5,
)

The tricky part of using this model is getting the correct data format. The yield_curve dataframe in the expression above requires:

• Annualized log-yields for zero-coupon bonds
• Observations (index) must be in either monthly or daily frequency
• Maturities (columns) must be equally spaced in monthly frequency and start at month 1. This means that you need to construct a bootstraped curve for every date and interpolate it at fixed monthly maturities

Examples

Updated estimates for the US are available on the NY FED website. The file example_us reproduces the original outputs using the same dataset as the authors.

The jupyter notebook example_br contains an example application to the Brazilian DI futures curve that showcases all the available methods and attributes.

I would like to thank Emanuel Moench for sharing his original MATLAB code in order to perfectly replicate these results.
