Short Term Spreads

Putting the Spring 2023 Spike In Perspective

Short Term Yields

Why are spreads blowing out?

A couple of possible reasons:

  1. Debt Ceiling: Fears of missing payments on X-date increase demand for short term bills, thereby depressing yields.

  2. SVB: Small and mid sized banks may be scrambling for high quality collateral, increasing demand for short term bills, thereby depressing yields.

Histogram

The max spread was 1.69% on 21Apr2023, which had a z stat = 10.94

Relative Spread

Adjusting for the level of the yields, today’s spread is not as dramatic as that which we experienced during the Great Recession when yields were only half as high.
