Frequently Asked Questions (FAQs)

Q:What is the 10Y-2Y Treasury yield curve spread (T10Y2Y)?

The 10Y-2Y spread (T10Y2Y) calculates the yield difference between 10-Year and 2-Year US Treasuries. It is the premier bond market barometer for the US macroeconomic cycle.

Q:Why is yield curve un-inversion (steepening) historically a critical recession signal?

While an initial yield curve inversion warns of future economic strain, the actual economic downturn and stock market volatility historically coincide with the un-inversion phase (when the curve re-steepens above 0%), often driven by emergency Fed rate cuts.
