How Interest Rates and Energy Prices Interact: A Technical Map

Lately the tone around some political headlines feels a little softer. At first the narrative was that things would be resolved after a certain event, and now there's more talk about an earlier timeline. On Musafa's Time Multiple Matrix, I find myself watching less whether a deal actually happens and more how the tone itself is shifting. That shift is what the market seems to be paying attention to.

This post is for personal observation and educational purposes only and is not investment advice. All decisions are your own responsibility.

1. The center looks like oil

The news cycle is full of war and ideology, but what I've kept coming back to is crude. When WTI holds above around the $90 level, inflation data tends to respond, and when inflation moves, the Fed's path tends to shift with it. War feels like the cover story - underneath, it often comes back to energy. That lens also helps explain why a Big Tech Bellwether can hold near highs while highly volatile digital value stores have pulled back from around 58K to around 81K and bounced. Same breath, different heart rate. I see this as momentum balance tightening.

2. The yield curve question

If you zoom out from 1994 to 2026, Fed Funds and oil have moved together more often than not. Around 1998 and again around 2019, what looked like insurance cuts was followed by a period where markets actually found some momentum. Around 2001 and 2008, after pushing near top levels, the turn came with a pick-up in volatility. Right now Fed Funds around 3.63% and WTI around $86 are both sitting near resistance. It leaves me wondering whether we're looking at a brief pause or the start of a deeper corrective phase. If oil pulls back hard, I'll be watching whether it's a healthy pullback from easing supply or a softer one tied to demand. This is my own reading of the green line as a momentum balance line.

3. When the bellwether and the curve diverge

The 10Y-2Y spread is back to around 0.26%, just barely positive. History shows that around 1980, 1990, 2002, 2008 and 2020, when the spread went deeply negative and then flipped positive, the economy often started to wobble. With oil bouncing near around $95, it doesn't feel easy for rates to come down quickly. I remember 2008 - oil ran toward around $140 while the curve was normalizing, then later slipped toward around $40 as volatility expanded. How risk around Iran evolves looks like a variable that feeds into the rate story as well.

4. What high yield spreads are telling us

Since around 2022, the spread has been pinned near the floor while a Big Tech Bellwether near 26,876 keeps holding near highs. We saw a similar gap around 1999 and 2007, where the curve turned first and the index followed much later. This is what I mean when I say same breath, different heart rate. If the gap closes because the curve rises to meet the index, it can be a gentle process. If the index adjusts toward the curve, it can come with expanding volatility.

High yield spread is one of my favorite ways to read market tension. Around 8% feels tense, around 4% feels relatively calm, and around 2% feels very calm. Around 1997, 2007 and 2020, when the spread touched lows like around 2.68%, it often lined up with index tops. When everyone feels comfortable, spreads get tightest, and that's often when risk isn't fully priced in. So even if oil comes down, I want to ask what kind of pullback it is.

Putting it together

There's a shift in tone from after an event to before it. Behind that, I see sticky inflation tied to oil interacting with policy rates. A sharp pullback in oil isn't something I'd frame as a certainty, more as one possible scenario that could develop. And if it does, I think it matters whether it comes from easing supply or softening demand. The four charts are just reminders from history not to get too comfortable even in calm stretches. Same breath, different heart rate - an index holding up top while the curve tries to climb from the bottom. How that gap gets filled is probably what writes the next chapter. This is how I read the Time Multiple Matrix.
