Latest / Energy Economics with Fexingo: Oil Prices, Renewables, and the Cost of Power / Why Oil Is Surging While Solar Stocks Crash in July 2026
Transcript
- Lucas: Crude oil just had its best week in months, and solar stocks just had their worst. That's not unusual in itself — energy markets rotate all the time. But the scale of the move is worth talking about. Luna: Yeah, WTI is up seven percent in five days. That's a real spike. And the Invesco Solar ETF, TAN, is down more than seven percent over the same stretch. Lucas: Right. So let's anchor this. July 8th, 2026 — WTI crude at $73.53, Brent at nearly $78. That's an eight-and-a-half percent weekly gain for Brent. Meanwhile, Enphase Energy — ticker e n p h — lost ten percent this week alone. First Solar, f s l r, down three percent. The divergence is as wide as we've seen all year. Luna: And the obvious question is: what changed? Because a week ago, oil was drifting around $68. Then suddenly it's spiking. Lucas: The trigger is pretty clearly geopolitical. There's a headline from this morning: President Trump said he's 'not sure' he wants an Iran deal, as tensions in the Strait of Hormuz keep escalating. That's a significant shift in tone. Markets had been pricing in some kind of diplomatic resolution that would bring Iranian barrels back into the market. Now that's uncertain again. Luna: And the Strait of Hormuz is where about a fifth of global oil passes through. Just the risk of disruption there can move prices. Lucas: Exactly. You don't even need an actual blockade. The threat premium alone is enough to push Brent from $68 to $78. But here's the thing — while oil is rallying on a supply scare, solar stocks are getting crushed by something completely different: interest rates. Luna: Because the Fed minutes came out today from the June meeting, and they showed a split. Some officials wanted to cut rates, others wanted to hold. Lucas: Right. The market read that as: rates are staying higher for longer. And higher rates are terrible for renewable energy stocks. These are capital-intensive businesses — they borrow money to build solar farms and wind projects. When the cost of borrowing goes up, the net present value of future cash flows goes down. Simple math. Luna: So oil is spiking on a supply shock risk, and solar is dropping on a rate shock. Two completely different narratives in the same week. Lucas: And yet, not every clean energy stock is getting hit. Look at NextEra Energy — ticker n e e — the big utility-scale renewable operator. It's actually up one and a half percent this week. So the selloff is concentrated in the pure-play solar manufacturers and installers. Luna: That's interesting. Why would NextEra hold up when Enphase is down double digits? Lucas: Part of it is diversification. NextEra has a regulated utility business that generates stable cash flow, regardless of what rates do. Enphase is purely residential solar and battery storage — more discretionary, more sensitive to financing costs. When mortgage rates are up, people are less likely to put solar panels on their roof. Luna: And we've also got inflation data still running a bit hot. CPI came in at 334 for May, up from 332. Core CPI is 336. So the Fed doesn't have a lot of room to cut. Lucas: The ten-year breakeven inflation rate ticked up to 2.25 percent. That's still within the Fed's comfort zone, but it's not falling. The bond market is basically saying inflation is sticky. And sticky inflation means sticky rates. Luna: So for oil, the question is: does this rally have legs? Or is it just a geopolitical premium that fades if tensions ease? Lucas: I think it depends on whether there's an actual supply disruption. Right now, no barrels have been taken off the market. Iran is still exporting — in fact, earlier this year they were selling at a premium because of the risk. But if something happens in the Strait, you could see Brent spike above $85 quickly. If diplomacy resumes, we could be back at $68 just as fast. Luna: And on the solar side, it's really all about the rate path. If the next CPI print comes in cool, you'd expect a relief rally. Lucas: Absolutely. But until then, we're in this two-speed energy market. Oil is trading on geopolitics, solar is trading on macro. And they're pulling in opposite directions. Luna: It also means that if you're an investor trying to hedge energy exposure, you can't just buy 'energy' and call it a day. The sector is not monolithic. Lucas: Which brings up a broader point. If you follow this show regularly, you've probably noticed we spend a lot of time disentangling these cross-currents. And that kind of analysis takes time and resources. Quick honest thing — a handful of listeners chip in monthly through buy me a coffee dot com slash fexingo, and that's literally what funds making this many of these episodes possible. Luna: Yeah, we keep the show ad-free because of that support. It's a small group, but it makes a real difference. If walking through the economy with us has made something click, that's the way to keep it going. Lucas: Anyway, back to the divergence. The other thing worth watching is the oil equities themselves. Exxon is up three and a half percent this week, Chevron up six. So the stocks are following crude higher, which isn't always the case. Sometimes refiners get squeezed when crude spikes, but right now the whole sector is rallying. Luna: And the broader energy ETF XLE is up almost five percent. So investors are betting that this oil rally sticks, at least for now. Lucas: I'd be cautious about extrapolating too far. The oil market has a history of pricing in a crisis premium and then giving it back when nothing happens. But the clean energy selloff feels more structural — it's about the rate regime, not a headline. Luna: So if you're a long-term investor in renewables, you're basically waiting for the Fed to pivot. And that could be months away. Lucas: Right. In the meantime, the two stories — oil and solar — are telling us very different things about where the economy is headed. One is about scarcity and geopolitics. The other is about the cost of capital. And for now, both are moving fast. Luna: It's a fascinating moment. We'll keep watching how these stories evolve. Lucas: Absolutely. Next week we'll look at whether the natural gas market is about to decouple from oil again. Henry Hub is flat at $3.21, but summer cooling demand could change that. Luna: Sounds like a plan. Thanks for listening.
