Oil Plunges 3.7% as Tech Selloff Deepens and Bond Yields Keep Climbing

Crude oil stole the headline in the stock market today, but it wasn't the only thing falling. WTI crude cratered -3.66% to settle at $101.56/bbl, a sharp reversal after last week's run toward $109. The drop came as traders weighed the uncertain path of the Iran conflict and what elevated energy prices mean for an already jittery bond market.

The pullback in oil didn't translate into broad relief for equities. The Nasdaq Composite dropped -0.51%, posting back-to-back losses as memory chip stocks dragged the tech sector lower. The S&P 500 slipped -0.07%, barely red but red nonetheless.

Only the Dow Jones managed to stay green, adding +0.32% on strength in energy and defensive names. It was a split-personality session: old economy up, new economy down.

Market Scorecard

The VIX actually fell -2.28% to 18.01, which tells you the selling wasn't panicked. Treasury yields continued their grind higher, with the 30-year sitting at 5.147% and the 10-year at 4.623%, each adding a couple of basis points. The bond market is still the loudest voice in the room right now.

Why Did Micron and Seagate Drag the Chip Sector Lower?

The tech damage today had a specific address: memory chips. Seagate fell 7% after its CEO said at a JPMorgan conference that new factories would "take too long." That comment hit a nerve.

It confirmed fears that the memory chip industry doesn't have the capacity to meet soaring demand, and the market punished the entire group.

Micron Technology dropped 5% in sympathy. Western Digital and Sandisk each lost 5% as well. The contagion spread to the broader AI trade, with Nvidia and Broadcom each slipping about 1%. When capacity concerns hit the supply chain, traders don't wait around to sort out the details.

This is the second straight session of tech weakness. The Nasdaq-100 dropped 1.5% on Friday, its worst single-day performance since March 27, as the global bond yield spike punished growth names. Monday's chip selloff just piled on.

Why Are Rising Treasury Yields Pushing Growth Stocks Lower?

The bond market isn't done sending messages. Friday's surge in sovereign yields around the world carried into Monday's session, even if the moves were more modest. The 30-year Treasury eclipsed 5% last week for the first time in nearly a year. U.K. 30-year Gilt yields scaled to levels not seen since the late 1990s. Japanese long-dated bonds joined the selloff too.

For growth stocks, this is a direct headwind. Higher yields raise the discount rate on future earnings, and tech companies with stretched valuations feel it first.

Ed Yardeni, the market veteran who coined the term "bond vigilantes," wrote Monday that incoming Fed Chair Kevin Warsh may need to push for a rate hike rather than cuts to establish credibility. Current market pricing implies a 42% chance of a rate increase by year-end.

Warsh has previously said he believes the Fed can lower its benchmark rate from its current 3.5%-3.75% range. But a recent surge in inflation, driven largely by the Iran conflict and other underlying factors, has forced markets to reprice expectations entirely. The bond vigilantes, it seems, aren't waiting for the Fed to catch up.

What Is Today's Sector Rotation Telling Traders?

Sector Performance

Energy (XLE, +1.87%) topped the leaderboard despite oil's sharp drop on the day, likely reflecting the sector's recent momentum from elevated crude prices and ongoing Middle East tensions. Consumer Staples (XLP, +1.50%) and Financials (XLF, +1.24%) rounded out the top three, a classic defensive rotation when growth names are under pressure.

At the bottom, Technology (XLK, -1.07%) was the clear laggard. The memory chip selloff was the main drag, but rising yields applied pressure across the entire sector. The nearly 3-percentage-point spread between the best and worst sectors tells you this was a rotation day, not a broad selloff.

Berkshire's Portfolio Shakeup Moves Individual Names

Berkshire Hathaway disclosed its latest quarterly holdings on Friday, and the market reacted Monday. The biggest surprise was a new $2.6 billion stake in Delta Air Lines, a return to the airline industry six years after Warren Buffett dumped the entire sector during the pandemic. Delta shares jumped more than 3% at one point.

Berkshire also initiated a position in Macy's, which climbed more than 1%. The conglomerate significantly increased its stake in Alphabet, making the Google parent its seventh-largest holding.

On the sell side, Berkshire trimmed its Chevron position and exited several names likely tied to former portfolio manager Todd Combs.

Looking Ahead

The stock market today closed with a clear message: the bond market is in charge. With the 30-year Treasury above 5% and the Fed's June FOMC meeting approaching under new Chair Kevin Warsh, the tension between dovish expectations and hawkish market pricing will only intensify.

Oil prices remain the wild card. Evercore's Roger Altman warned Monday that a sharp rise in crude could destabilize markets and trigger "the second big inflation shock of this decade after COVID," especially if prices climb toward $150. With Iran-U.S. tensions still unresolved, that risk isn't going away.

Traders will be watching whether the tech selloff finds a floor or whether rising yields continue to pull money out of growth and into value. Two straight days of Nasdaq losses after record highs is worth paying attention to, even if the VIX says the broader market isn't panicking yet.
