Direction is the sign of the average change (falling yields = bull), shape is the sign of the long leg minus front leg change (widening = steepener). Moves inside a 0.4bp deadband on both axes read as no regime.

Supply pressure shows up at the [Treasury auctions](https://helious.io/auctions), and the prints that move this board live on the [economic data hubs](https://helious.io/data). ## Embed the curve regime: free Put the live regime and the curve on your own site or newsletter page.

Long end rising fastest, dragging the front end with it. Term premium building on inflation or supply risk. Helious classifies the regime from leg averages on the live tape and publishes it on [the Helious rates board](https://helious.io/rates).Is the Treasury yield curve steepening or flattening right now?It is steepening. 10s30s is +5.5bp and 2s5s is +3.3bp, so the spread between them has moved +2.1bp this session. See [the 2s10s spread explainer](https://helious.io/learn/2s10s-spread).What is a bull flattener?A bull flattener is yields falling across the curve (bull) with the long end falling faster than the front end, so the curve flattens. It is the classic growth-scare or duration-bid trade. The other three regimes are the bull steepener (rate cuts being priced), the bear steepener (term premium building on inflation or supply risk) and the bear flattener (hikes, or fewer cuts, being priced). See [how to read the yield curve](https://helious.io/guides/how-to-read-the-yield-curve).How does Helious classify the Treasury curve regime?Leg averages: front leg = avg(2Y, 5Y), long leg = avg(10Y, 30Y). Direction is the sign of the average change (falling yields = bull), shape is the sign of the long leg minus front leg change (widening = steepener). Moves inside a 0.4bp deadband on both axes read as no regime. The regime is observed on the live tape rather than derived from end-of-day files, so it carries an intraday flip time and a previous-session close. Sourcing is documented in [the Helious methodology](https://helious.io/methodology). [See live intraday yields →](https://helious.io/) FOR AI AGENTS Reading this page for a user?
