The June ceasefire is dead, the Strait of Hormuz has a live naval blockade, and yesterday the bond market confirmed exactly what kind of crisis this is: yields rose 2.4 bps while equities sold off and gold held $4,001, which is an oil-driven inflation re-acceleration signal, not a growth scare. Stagflation setup, standard flight-to-bonds playbook broken. S&P futures off 0.9%, Nasdaq off 1.7%, and the KOSPI's 6.4% overnight collapse are the opening act, with WTI at $79.86 as the number that settles today's argument.

Yesterday's US close was ugly at the index level, uglier under the hood. The S&P 500 fell 0.5% to 7,533, the Nasdaq dropped 1.5% to 25,882, and the Dow shed 0.2% to 52,553. Small caps went nowhere, closing flat at 2,974. The real story was cross-asset: gold held $4,001, the 10Y yield ticked up 2.4 basis points to 4.569%, WTI crude surged 1.2% to $79.86, and the USD index barely budged at 100.78. Bonds and gold refused to sell off while equities fell, which is the classic stress signal.

Two catalysts drove the selloff. First, the June ceasefire between the U.S. and Iran officially collapsed on July 16 when the U.S. launched airstrikes on Iranian military installations near the Strait of Hormuz and reinstated a naval blockade of Iranian ports. Iran retaliated with drone and missile strikes on U.S. bases in Jordan, Kuwait, and Bahrain, and declared the strait a red line. That is not a headline you fade. Think of the Strait of Hormuz as a one-lane bridge carrying 20% of the world's seaborne oil: any credible threat to close it is a supply shock priced in immediately. Second, Netflix dropped 9% after-hours after projecting Q3 revenue of $12.86 billion against a $13.00 billion consensus, dragging the entire consumer discretionary and ad-tech complex lower into this morning.

For your portfolio, the cross-asset read is clear. Energy ETFs (XLE, XOP) are the direct beneficiary of a genuine supply disruption threat, not a rumor. Oil at $79.86 with the Hormuz situation unresolved has a straightforward path higher. Defense names inside ITA will also attract flows if this escalates further. On the other side, technology (QQQ, SMH) is facing a double hit: the geopolitical overhang on AI capex sustainability, flagged by Nvidia and chip names rotating lower even before Netflix, plus now a high-profile earnings miss that validates the valuation concern. TLT is the interesting one: yields crept up yesterday despite the flight to safety, suggesting the market is sniffing an oil-driven inflation re-acceleration rather than a pure growth scare. Gold above $4,000 (GLD) is the cleanest hedge here.

Going into today, S&P futures are off 0.9% and Nasdaq futures are down 1.7%, pointing to a rough open. The KOSPI's 6.4% collapse, partly driven by the Bank of Korea's surprise rate hike and tech sector pressure, is the most extreme APAC signal and flags genuine regional stress. The Nikkei fell 4.0%. Europe is flat so far in early trading, which is not a vote of confidence. The key swing factor today is the 10:00 AM ET New Home Sales print, which is a secondary mover at best given what's live in the Middle East. The real pivot point is whether WTI breaks above $80 on the open, which would confirm energy longs and deepen tech pressure, or fades back, giving bulls a reason to buy the dip into the weekend.
