• Dow Jones Industrial Average futures finished Monday virtually unchanged from Friday's close despite a weekend of sharply escalating US-Iran tensions.
• President Trump confirmed the US had fired on and seized an Iranian-flagged cargo ship in the Gulf of Oman, while Iran walked away from US-brokered peace talks in Pakistan.
• West Texas Intermediate (WTI) crude jumped 5% above $88 per barrel as Strait of Hormuz shipping traffic remained restricted and the ceasefire neared expiry.
• Oil, not equities, did the work of pricing weekend developments, with the blue-chip index holding its ground even as the list of near-term risks lengthened.

Dow Jones Industrial Average (DJIA) futures gapped lower at Sunday's reopen toward the 49,100 area but ground steadily higher through the US session to settle only marginally below Friday's closing handle near 49,400. The benchmark ended effectively flat on the day, with the S&P 500 down 0.4% and the Nasdaq Composite off 0.5%. Given the scale of weekend developments, a boarded tanker in the Gulf of Oman, collapsed peace talks, and a ceasefire expiring this week, the refusal to discount any meaningful risk premium stood out.

A weekend of deterioration, barely a flinch

The backdrop worsened on several fronts at once. Trump on Sunday said the US had fired on and seized an Iranian-flagged cargo vessel in the Gulf of Oman, citing prior US Treasury sanctions for "illegal activity" as grounds. Iran then declined another round of US-brokered talks in Pakistan, and Trump threatened to destroy Iranian power plants and bridges if Tehran does not come to terms before the current ceasefire lapses later this week. Yet DJIA futures opened roughly three-quarters of a percent lower and spent the session retracing almost all of that gap, closing about where they started Friday. For an index that fell hard just weeks ago on thinner provocations, the stability was hard to pin on geopolitics alone.

Oil does the pricing work

If equities would not move, Oil did. WTI popped 5% above $88 per barrel, with Brent up a similar amount above $94. The bid followed confirmation that vessel traffic through the Strait of Hormuz was restricted again by Saturday, with Iranian state media arguing the US "did not fulfill their obligations" after Iran had briefly declared the chokepoint reopened following the Iran-Lebanon ceasefire. Trump has reiterated that the US naval blockade of the strait will remain in place until Iran accepts Washington's terms. Crude traders, exposed directly to physical supply risk, moved first and moved hard.

The "rearview mirror" call keeps holding

"The war with Iran is now in the rearview mirror for the market," David Wagner, head of equities and portfolio manager at Aptus Capital Advisors, told CNBC. The confidence is striking given the news mix. Wall Street is coming off a week in which the S&P 500 gained 4.5% and the Nasdaq Composite popped around 7%, with the Nasdaq notching its 13th consecutive winning session on Friday, matching a streak last seen in 1992. Traders who bought every dip through recent weeks have been rewarded, and that conditioning was on full display again on Monday.

Software leads, defensive bid absent

Inside the tape, software was the standout factor on the long side, with the iShares Expanded Tech-Software Sector ETF (IGV) last up 0.6%. What was conspicuously missing was any meaningful rotation into defensives on a day featuring a seized foreign vessel, a cancelled round of peace talks, and a Presidential threat to strike national infrastructure. With no tier-one US economic data on today's docket, direction into Tuesday will likely be dictated by incremental US-Iran headlines, any shift in the ceasefire posture, and whether Oil holds above the $88 handle into the overnight session.
