The oil shock just broke mortgage costs. Equities haven’t noticed.
Transcript
Tom Hey, real quick—oil's up over a hundred percent this year, mortgage costs are spiking, and the bond market is screaming. But the S&P's just vibing at highs. Something's got to snap. We're breaking it down right now.
Marie Welcome to Investment Flash, London Edition, Monday May eighteenth. I'm Marie, with Gerald and Tom. And Tom, you are way too caffeinated for a Monday morning.
Tom You're not wrong, but look—when the oil ETF is near its fifty-two-week high and the long-term Treasury bond ETF is pinned to its fifty-two-week low, it's hard not to be. Gerald, remember our buy oil call from yesterday's weekend show?
Gerald Yeah, I was just going to say—the oil fund ticked up again in Friday's session, so your call's looking solid. But let's not get carried away—oil's up a hundred and fifteen percent year to date. At some point it runs out of steam.
Tom Buddy, runs out of steam? With Iran war keeping supply tight and Europe scrambling for jet fuel? I don't think so.
Marie Hold on—Tom, the FT reports European refiners are ramping up and importing from the US and Africa to avoid shortages. Lufthansa is confident. The supply panic is already being managed.
Gerald To be fair, Marie, the oil move is now hitting the housing market. Mortgage costs are jumping. Both the FT and Bloomberg flagged it—the homebuilder ETF slid three point eight percent last session. That's real economic friction.
Tom So you're saying oil and bonds are doing the Fed's job for them? Tighter financial conditions without a rate hike?
Gerald Exactly. And Yardeni is screaming at the Fed to drop its easing bias. If they don't, the bond rout could accelerate. Ten-year yield is climbing, JGBs are leading, and Indian equities—INDA—are down twelve percent year to date as capital flees.
Marie But here's the thing—the S&P 500 ETF is still within a hair of its high. That divergence is massive. Either bonds are wrong, or equities haven't caught up.
Tom No but that's exactly my point! Japan equities are a perfect example. Companies are on track for another record profit year—sixth in a row—AI semis, bank margins. The hedged Japan ETF is up seventeen point six percent year to date. The real economy is humming.
Gerald Right, but Tom—the ten-year JGB yield just surpassed the Topix dividend yield for the first time since two thousand seven. That's a two-decade signal. If investors can get a higher yield from bonds without equity risk, that rotation could hit the unhedged Japan fund hard.
Tom Come on Gerald, the hedged trade—the WisdomTree Japan Hedged Equity ETF—sidesteps that. Weak yen, profit momentum. That's the play.
Marie Wait, wait a second. We're also talking about crypto trusts in Japan? SBI and Rakuten are launching them, Nomura looking in. That's institutional adoption. But Bitcoin slumped below seventy-seven thousand on the same oil shock. Which narrative wins?
Gerald Yeah, look—crypto right now is a tug of war. On one side, you've got regulatory green lights in Japan. On the other, macro headwinds. I'd rather buy SBI Holdings directly—they're the ones set to benefit from the trust launch regardless.
Tom SBI is a clever pick, I'll give you that. But I'm more focused on the energy trade. Exxon gained four percent last session. European jet fuel demand is underpinning it. That's a pure oil play with a refiner tailwind.
Marie Alright, but let's not forget the housing angle. If mortgage costs are hurting homebuilders—the homebuilder ETF down five percent in the past week—that's a direct hit from oil inflation. So are we short the Treasury bond ETF or short homebuilders?
Gerald Why not both? The Treasury bond ETF is already at its fifty-two-week low, and rising yields aren't done. And the homebuilder ETF is twenty-two percent off its high. I'd actually say short UK equities too—the UK ETF slid two point three percent last session on the Burnham political risk. Sterling bearish bets are piling in.
Tom Oh, the Burnham story! Hedge funds are suddenly scared a Manchester mayor becomes PM and loosens the purse strings? That's—that's quite the bet.
Gerald Alright, Tom, don't laugh—Bloomberg reported actual option flow last week. When asset managers short sterling structurally, it can get ugly for UK assets. The UK ETF's down seven percent from its high.
Marie So between Japan crypto, oil shock, bond rout, and now UK political risk—we're swimming in macro uncertainty. And no one's talking about credit spreads? With yields surging, investment grade and high yield spreads should be widening. They're not.
Tom That's—that's actually a really good point. If credit isn't stressed, maybe the bond selloff isn't systemic yet. It's just an inflation repricing.
Gerald For now, sure. But Yardeni's entire argument is that the Fed loses control if they don't act. Honestly, his columns are starting to read like a breakfast warning from your central-banker uncle—every meal, same warning.
Tom Ha—brutal. But look, EM contagion is real. India's INDA near its fifty-two-week low. I get it.
Marie Speaking of risks, what about Samsung? There's a strike set for Thursday demanding fifteen percent of operating profit as bonuses. Tom, you're the tech guy—is that a short?
Tom Short Samsung? Yeah, I hate to say it, but a production halt of any kind would hit profit estimates. Though honestly, the broader AI semis story is still intact.
Marie Tom, shorting Samsung now? That's calling the top on memory chips—what is this, the sixth time this cycle?
Tom Hey, the strike is real—this time it's different!
Gerald Right, so that's another layer—tech supply risk in Asia. And we haven't even touched the China property distress. Evergrande liquidators are going after PwC for eight point four billion dollars in court today.
Marie The audit industry fallout from that is huge. But the KraneShares China Healthcare ETF is down six percent year to date—it's a decent proxy for China risk. Honestly, the property overhang is still there, and it's not priced into global equities.
Tom Alright, Gerald—between bonds, UK, China, and sterling, you're like the grim reaper of the show today.
Gerald Yeah, well, someone's got to keep an eye on the downside while you're chasing oil highs.
Marie Okay, let's pivot to the most original take. The FT has a piece that the fate of OpenAI's trillion-dollar I P O is going to be decided in an Oakland jury room. Elon Musk's lawsuit could derail the whole thing.
Tom For real? That's wild. I thought the biggest risk to OpenAI was competition or regulation, not a courtroom drama over non-profit governance.
Marie That's it—the whole valuation hinges on whether jurors think the company acted properly. It's one of the most massive IPOs in history, and it could come down to a layperson's verdict.
Gerald That's absurdly unpredictable. But it also highlights how much tech valuations depend on story, not just cash flow. If the I P O gets delayed or priced lower, the whole AI tech basket could wobble.
Tom But buddy, the AI demand is real. Japan's record profits are built on it. A courtroom squabble doesn't change that.
Marie I'm going to push back here, Tom. The market often conflates narrative and fundamentals. If OpenAI's I P O stumbles, it could deflate the AI premium globally. That hits the hedged Japan ETF too, even if profits are real.
Tom Fair, but—that's a big 'if'. Lawsuits can settle. I'd rather bet on the hedged Japan trade than short AI.
Gerald Alright, let's bring it all together. Our view this morning: The equity-bond disconnect is razor-sharp. The Treasury bond ETF at lows, the S&P 500 ETF near highs. Something gives. The cleanest expression is a pair trade—long the hedged Japan ETF, short the homebuilder ETF and UK equities.
Tom That's it.
Marie Nailed it.
Tom And I'd add—keep riding oil. The oil fund isn't done.
Marie But watch for a ceasefire rumor. That would flip the script fast. CTAs would dump oil and rotate into bonds. The Treasury bond ETF would rip.
Gerald Right, so while we're all piling on the short duration trade, a reversal is crowded. That's the risk. But for now, follow the flows.
Tom Exactly. And as always, none of this is investment advice. Just our fast-and-furious take on the morning's signals.
