Latest / Energy Economics with Fexingo: Oil Prices, Renewables, and the Cost of Power / Why Solar Stocks Are Surging While Oil Craters in May 2026
Transcript
- Lucas: So, oil is having its worst week in months. WTI crude just fell through ninety-seven dollars a barrel, down more than ten percent in five trading days. Brent is barely hanging on above one hundred. Luna: Meanwhile, solar stocks are on fire. Enphase Energy is up nearly twenty-nine percent in that exact same window. Lucas: Exactly. And that's the story today: the biggest week to week divergence we have seen this year between the old-energy barrel and the new-energy panel. It is not a small blip. The S&P Clean Energy Index is up five percent. The oil and gas ETF, XLE, is down nearly two percent. Capital is moving. Luna: What's the proximate cause for the oil crash? Because it feels like everyone is blaming geopolitics, but I want to hear the actual numbers. Lucas: Right. The headline catalyst is Trump saying on Sunday that Iran talks are proceeding in a 'constructive manner.' That alone knocked five percent off oil prices in a single session. But look deeper: Carlyle's Jeff Currie said this morning that oil markets are at 'tank bottoms' in Asia and Europe isn't far behind. That is a storage signal. Physical barrels are backing up. Luna: So it's not just a headline. The actual supply-demand balance is looser than people thought. Lucas: Correct. The five-day move in WTI — from roughly one hundred eight to ninety-six sixty — is the kind of drop you usually only see when a recession is priced in. But we are not in a recession. GDP is still positive. Jobless claims are low. So the market is saying: the risk premium that was baked into crude since the Iran escalation is being removed, and there is no physical tightness underneath to catch the fall. Luna: And on the solar side, what is driving that? Enphase specifically is up almost twenty-nine percent in five days. That is not just a sympathetic bounce. Lucas: No, that is company-specific. Enphase reported a new product line — their next-generation IQ microinverter — and analysts upgraded the stock on margin expansion potential. But the broader clean energy rally — First Solar up ten percent, the solar ETF TAN up five percent — that is rotation. Money is leaving energy commodities and energy equities and moving into renewable infrastructure. Luna: So the thesis is: oil drops, clean energy rises. But correlation is not causation. Can we trace the actual dollars? Lucas: We can approximate. The XLE, the energy sector ETF, saw outflows of about four hundred million dollars in the past week, based on flow data. Meanwhile, the clean energy ETFs — ICLN and TAN — saw net inflows of roughly one hundred fifty million combined. Not huge in absolute terms, but the direction is unmistakable. Luna: And that is happening even though natural gas is also down. Henry Hub is at three-oh-two, down three percent. So it is not a fossil fuel versus renewable story across the board. It is specifically oil. Lucas: Right. Natural gas is its own beast — storage is high, production is resilient. But the oil move is the big one because it opens up a question that a lot of portfolio managers are wrestling with: is this a tactical rotation ahead of a potential Iran deal, or is it structural? Are we finally seeing a peak in oil demand expectations? Luna: Honestly, if walking through the economy with us has made something click, that is the link — buy me a coffee dot com slash fexingo. It keeps the show ad-free and independent. Lucas: Yeah, genuinely. We don't do sponsors, we don't do ads, and that is because some listeners choose to support the show. It is a small thing that makes a big difference. Luna: Exactly. So back to the divergence — Lucas, you mentioned structural versus tactical. What would make this more than a one-week anomaly? Lucas: The key is the forward curve. When we look at WTI futures, the backwardation — that premium for immediate delivery over future delivery — has collapsed. It was over five dollars a month ago. Now it is barely a dollar. That tells you the market expects oil to stay weak. If the curve flattens further or goes into contango, that is a signal that storage is filling and prices could stay suppressed. Luna: And on the solar side, the forward picture looks different. The IRA subsidies are locked in, module prices are falling, and installation rates are accelerating. So even if oil stabilizes, solar might still have momentum. Lucas: That is the bull case. But I want to be careful: solar stocks are notoriously volatile. Enphase is still down more than fifty percent from its 2022 high. So this week's rally is a bounce, not a breakout — unless the macro backdrop shifts permanently. Luna: What would that shift look like? Lower inflation? Lower interest rates? Because higher rates hurt solar more than oil. Lucas: Exactly. Solar is a capital-intensive, long-duration asset. The ten-year breakeven inflation rate ticked up to two point four percent this week. That is not a dramatic move, but if inflation stays sticky, the Fed stays on hold, and that keeps financing costs high for solar projects. Oil, on the other hand, benefits from inflation because it is a shorter-cycle commodity. Luna: So the divergence this week might be more about geopolitics and storage than about a fundamental shift in the cost of capital. Lucas: I think that is right for now. But watch the flows. If we see another week of clean energy inflows while oil continues to slide, that becomes a trend. And trends in capital allocation tend to persist. Luna: One more data point: core PCE came in at one hundred twenty-nine point three for March, up slightly. So the inflation picture is not giving the Fed room to cut. That argues against a sustained clean energy rally. Lucas: Agreed. But the market is forward-looking. If the inflation data softens over the summer, solar could rip higher. If it doesn't, this week could be a head fake. Luna: So what is the one thing a listener should take away from this episode? Lucas: That the energy market is pricing two different worlds right now: one where oil loses its risk premium and falls, and another where clean energy gains momentum on policy and cost declines. We are living in the overlap, and it is creating unusual opportunities — and unusual risks.
