⚡ Lighthouse Weekly

This week's takeaway
For the first time in weeks, every tier of the credit stack widened together. CCC is still leading (+0.12 on the week, +0.37 over 30 days to 9.47%, 76th percentile of the past 3 years), but BB, Single-B, and the HY composite all moved wider on both 1-day and 5-day windows. Absolute levels are still historically calm — HY composite at the 10th percentile, IG at the 1st — but the direction has flipped from 'CCC is the only tell' to broad-based drift. Composite stress score now 41.6, up from 36.9 two weeks ago.

📊 The state of play

The dispersion story has broadened. Two weeks ago only CCC was widening; this week BB sits at the 7th percentile (up from 4th), Single-B at the 30th (up from 25th), and every tier is red on the day. Absolute levels remain calm — markets are not panicking — but the direction of travel changed. The 2Y is up 0.13 over the past month and the 10Y-2Y curve flattened 0.08 percentage points over 30 days to 0.42, so the rates backdrop is doing some of the tightening work for the Fed without the Fed having to act.

👀 Watching next week

Whether the dispersion accelerates or stalls.
BB and Single-B started widening this week but remain at calm absolute levels (7th and 30th percentile). The next step is whether they push meaningfully higher in the coming weeks. If yes, the regime has shifted. If no, this was a one-week wobble. CCC at the 76th percentile is the existing tell — watch whether it pulls the rest of the stack up with it.
