  • Flipped at 15:05 UTC from a bear flattener
  • Previous session (19 Aug 2026) finished as a bull flattener
  • 5-session trend to Aug 19 · BULL FLATTENER · 2Y -1bp, 30Y -5bp, 2s30s -4bp
  • Biggest mover: 10Y +4.7bp
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. Full methodology.

Reading the board

The 2s10s spread is the classic recession dial; SOFR anchors the front end; term premium is what the long end charges for duration risk. Supply pressure shows up at the Treasury auctions, and the prints that move this board live on the economic data hubs.

FAQ

What is the US Treasury yield curve doing today?
As of 20 Aug 2026 19:42 UTC, the US Treasury yield curve is a bear steepener: front leg (2s5s) +2.8bp, long leg (10s30s) +4.5bp, spread change +1.7bp. 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.
Is the Treasury yield curve steepening or flattening right now?
It is steepening. 10s30s is +4.5bp and 2s5s is +2.8bp, so the spread between them has moved +1.7bp this session. See the 2s10s spread explainer.
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.
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.
