Iran response
Trump: 'totally unacceptable'
Iran delivered a written response. Trump rejected it the same day.
Tehran handed its written reply to the 1-page MoU to Pakistani mediators Saturday morning. The offer accepts the framework’s structure — end the regional war, launch a 30-day window of detailed talks on Hormuz reopening, sanctions relief and nuclear restrictions — but with two material amendments. Iran demands “war compensation” and formal US recognition of Iranian “sovereignty” over the Strait of Hormuz; on the nuclear track, Iran offers to transfer a portion of its highly-enriched uranium stockpile to a third country (likely Pakistan or Oman) but explicitly refuses to dismantle its enrichment facilities. President Trump received the document Saturday afternoon and rejected it within hours, calling the proposal “totally unacceptable” on Truth Social and accusing Tehran of “playing games”.
Sun-night futures opened with the rejection priced in. Brent gapped +3.49% to $104.83 as ICE July reopened; WTI +3.94%. US equity futures all lower (~−0.3%), the dollar firmer (DXY 98.66), gold +1.1% on haven flow. Asia’s first session in the new regime was split — KOSPI tore through to a fresh ATH (+4.70%) on Korean shipbuilding capex read-through (Hanwha + HD Hyundai stand to benefit from any sustained US Naval posture in the Gulf), while Hang Seng and Nikkei traded heavy on the geopolitical re-rating. Hormuz throughput has slipped to ~5.5 mb/d as commercial traffic anticipates US escalation; the indicator remains RESTRICTED but the trajectory is the wrong direction.
Last week's scoreboard, with YTD on a switch
Each card opens with a Spotlight row driving last week’s narrative for that asset class. Friday’s prints captured a constructive close before Sunday’s rejection — Nasdaq logged its biggest weekly gain since November, Brent gave back nearly all of Monday’s spike, and the long end took the brunt of the curve move.

Where the dial sits after the weekend
A composite of six inputs — equity vol (VIX), rates vol (MOVE), oil vol, dollar range, credit spreads, and the Vault geopolitical-tension index — distilled into a single 0–100 score. Friday closed at 68 (firmly Constructive); Trump’s rejection of the Iranian response Sunday pulled the dial back to 42 (mid-Cautious).
Market Regime Gauge — composite risk score, 0 → 100
Friday's constructive 68 fell to 42 over the weekend — a 26-point slide on the Iran rejection alone.
Composite reading · Mon 11 May 2026, 06:30 GST. Inputs: VIX, MOVE, oil vol, dollar range, credit spreads, Vault geopolitical-tension index. Bands: 0–20 Risk-Off · 20–40 Cautious · 40–60 Neutral · 60–80 Constructive · 80–100 Risk-On.
How to position into a re-armed bracket
The Cappuccino’s Sunday probability map gets re-weighted on the back of Trump’s rejection: Bull falls to 20%, Base stays the dominant 50%, Bear lifts to 30%. Probabilities sum to 100. The cleanest single data print of the week is Wednesday’s April CPI; the second variable is the trajectory of the Iran-Trump exchange after the weekend rejection.
Bull · 20% probability
Trump softens — back-channel talks resume at lower ambition
Long oil exposure cut. Add equity beta on the gap. Cap-equipment chips (LRCX, KLAC, ASML) the cleanest expression. Targets: S&P 500 7,450+ · Brent <$95 · Hormuz RESTRICTED→ · US 10-Yr 4.30% · DXY −1%.
Vault Strategy Desk estimate
Base · 50% probability
Stalled — choppy range as both sides talk to their bases
Trim oil bid into rallies. Stay duration-light through Wed CPI / Thu Powell exit. GCC credit overweight maintained. Targets: S&P 500 7,250–7,400 · Brent $100–$108 · Hormuz RESTRICTED · US 10-Yr 4.40–4.55% · VIX 14–18.
Vault Strategy Desk estimate
Bear · 30% probability
Trump escalates — bombing threats become posture
Iron-condor structures on oil-linked equity. Long gold on dollar stress. Brent topside hedge sized to your portfolio's energy beta. Targets: S&P 500 −4 to −6% · Brent $115+ · Hormuz CLOSED · US 10-Yr >4.60% · VIX 22+.
Vault Strategy Desk estimate
CPI Wednesday, Powell's last day Thursday, Warsh's first day Friday
CPI Wednesday is the print of the week — and it arrives 24 hours before Powell’s last day at the desk. Warsh’s full-Senate confirmation vote slots into Tuesday; Walmart and Applied Materials Thursday are the consumer + cap-equipment read-throughs.
MON 11 May
Asia open · Sun-night futures gap · Bostic 10:00 ET
Asia first to price the rejection: KOSPI to ATH, Hang Seng heavy. Watch the Pakistan back-channel for any weekend response read-out.
TUE 12 May
Warsh full-Senate vote · US PPI 08:30 ET · HD, ONON AH
Senate floor vote on the new Fed chair. PPI sets the table for Wednesday's CPI. Iran follow-on statement window stays open through the session.
WED 13 May
US CPI April 08:30 ET — the print of the week · CSCO, JNJ AH
Williams and Daly speak. Hormuz transit count is the geopolitical read alongside the inflation number. Curve positioned for continuity; print decides duration.
THU 14 May
Powell's final day as chair · US retail sales · WMT, AMAT pre-mkt
Retail sales 08:30 ET. Walmart the consumer read, Applied Materials the cap-equipment read — AMAT is the cleanest read-through into the AI-capex cohort.
FRI 15 May
Warsh's first day as Fed chair · U-Mich sentiment · 30-day MoU window expires
Sentiment lands into the chair handover. If the MoU had been signed Saturday, today is when the 30-day window expires. GCC weekend-risk into Saturday is the close-out trade.
GCC credit had it right; now the equity gap has to widen back open
Last week’s GCC credit rally — UAE eurobond spreads tightening 15 bps, Saudi 5-yr CDS through the war-trigger level — was effectively pricing a deal that didn’t arrive Sunday. Sun-night repricing was mild but real: UAE 10-yr eurobond spreads back +4 bps overnight, Saudi 5-yr CDS +6 bps. DFM and ADX both expected to open down 0.8–1.2% reflecting the Sun-night gap; Aramco the cleanest read-through given the +3.5% Brent move. Doha 5-yr +3 bps. The credit gap that opened last week against equity will likely close back the other way today and tomorrow before settling.
For the rest of the week, the regional equity bid depends on whether Trump’s rejection escalates to action or remains a negotiating posture. The Vault house view at the open: GCC equity overweight maintained, but trimmed; oil-linked names (Aramco, ADNOC Distribution, energy-exposed utilities) outperform on any sustained Brent firmness; banking and developers are higher-beta and likely to give back more than they gained last week if Bear gets pricing weight. Hormuz throughput trajectory is the watch — if 5.5 mb/d slips toward 4 before Wednesday, the GCC equity print re-rates lower regardless of the Trump-Iran rhetoric.

Three things to watch this week
A bombing-bracket re-armed, a CPI print landing Wednesday, a Fed-chair handover Thursday-into-Friday, and a regional credit market that priced a deal that didn’t arrive. The Vol. 9 setup is dense on the macro side and binary on the geopolitical side.
01
01 · Breadth
Watch the breadth, not the level
Three records in a week with eight of eleven sectors green looks broad on the surface — but Tech alone contributed roughly 60% of the index move, and Energy gave back 3.8%. The S&P advance/decline and equal-weighted index are both lagging the cap-weighted print. If Energy stops fading next week, breadth confirms; if not, the Tech-only rally is at risk of a reversion bid.
02
02 · Iran
Iran's written response is the binary
The verbal walk-back from Rezaei was Thursday. Pakistani back-channels secured the written reply that arrived Saturday. With Trump's rejection now in hand, every constructive move since Tuesday afternoon is on the table for reversal. The Hormuz indicator stays RESTRICTED until it doesn't.
03
03 · Warsh
Warsh's full-Senate vote hits the curve
The Senate floor vote on the new Fed chair is keyed to Tuesday or Wednesday. Powell's measured Hoover remarks lowered the bar for a smooth handover; the curve is positioned for continuity. Asymmetric risk: a smoother-than-priced confirmation pulls the 30-year back toward 4.95%; a bumpy one pushes through 5.10%. Stay duration-light through Wednesday's print.
Vol. 9 starts at the wrong end of the regime gauge. The 26-point dial slide isn’t the risk — it’s the signal that hedges get cheaper before they get used.
