☕ Good Morning

The Ledger — 67 resolved today, 13 hit · OONI Brier 0.058 over 263, -2% vs base rate · FX Brier 0.252 over 2822, -5% vs base rate · 940 open, next resolves 2026-10-19

Happy Sunday. A quiet week on the macro front, but the details tell the story: new sanctions on Iran's financial network, coordinated network blocking continuing in Russia and Iran, and oil up nearly 3% while the dollar slipped. Here's what mattered this week — and what we're watching heading into Monday.

🎯 This Week's Calls

469 calls settled against external ground truth: 112 hit, 357 miss.

We missed cheaply on Colombia — we said 33% (base rate 26%) for currency depreciation and it didn't move. We hit on Uganda at 32% (base rate 25%) twice this week. Morocco went both ways: two hits, two misses, all at 34% against a 26% base rate. The misses cluster around FX calls where we're slightly above base — low-conviction, low-cost.

Our most divergent open call: Morocco at 38% for ≥1.5% depreciation by 2026-10-30 — +12pts vs its base rate of 25%. Resolves in twelve days.

📍 The Week That Was

1. OFAC targets Iran's overseas banking infrastructure Twelve new designations on October 15th, including Chabahar International Bank Overseas Company, Jazireh International Bank, and four individuals tied to financial facilitation under EO13902. This is the Treasury's most coordinated move against Iran's external banking channels since August. No corresponding UN action yet.

2. Russia and Iran lead weekly network blocking OONI recorded 46,905 confirmed blocks in Russia and 36,247 in Iran over seven days — the highest dual-country totals we've logged this quarter. Turkey (3,452), India (3,323), and Saudi Arabia (531) round out the top five. No new policy announcements from Moscow or Tehran; the blocking is ongoing infrastructure enforcement, not event-driven.

3. Oil rises as Hormuz and Bab el-Mandeb adjacencies hold elevated CII Crude oil ETF (USO) up 2.83% for the week. Iran at CII 85 sits on the Strait of Hormuz (~20% of global oil transits); Yemen at CII 92 flanks Bab el-Mandeb. No new incidents reported, but structural risk remains priced. Energy sector ETF (XLE) rose 2.52%.

4. U.S. deviation drops 5 points in 24h United States moved from deviation 14 to 9 on a structural level of 13. Driver not identified in this week's data.

5. Bellingcat investigation documents Gaza satellite imagery Viral Google Maps imagery showing Gaza destruction circulated widely this week. Bellingcat obtained more recent satellite imagery confirming extensive structural damage. We have no reliable displacement data past March — treat casualty estimates as low confidence.

6. Crisis Group flags Ethiopia-Eritrea escalation risk New report asks "How Close Are Ethiopia and Eritrea to All-out War?" Ethiopia sits at CII 64 (deviation +0). We're watching for troop movement reports or border incident escalation — neither confirmed yet.

7. Sudan holds steady at CII 90 with +6 deviation Sudan's deviation rose 6 points but held its 90 structural level all week. No new conflict events identified; the deviation appears noise rather than signal.

🌍 The Board: Weekly View

Movers Iran 85 (▼-3) — network blocking intensity sustained at 36,247 confirmed measurements; sanctions expansion on financial entities Sudan 90 (▲+6) — driver not identified in this week's data Somalia 85 (▼-5.6) — deviation fell from 5.6 to 0 by week's end after brief spike United States 13 (▼-5) — driver not identified in this week's data Pakistan 61 (▼-4) — deviation returned to baseline Venezuela 67 (▼-3) — deviation returned to baseline

Markets Crude oil ETF (USO) +2.83% — structural chokepoint risk unchanged, no new incidents Energy sector ETF (XLE) +2.52% — tracks with oil move S&P 500 ETF (SPY) -1.11% — broad risk-off posture Dollar index ETF (UUP) -0.28% — modest weakening Gold ETF (GLD) -0.18% — flat week Natural gas ETF (UNG) -3.88% — weather-driven, no geopolitical driver

What would change our mind: A sharp drop in OONI blocking measurements in Iran or Russia (sub-20,000 weekly in either) would suggest policy shift or technical circumvention — neither visible yet.

🙊 What We're Not Saying

• U.S. deviation drop: We logged a -5 point move in 24h. No driver in the data. Not explaining it.
• Sudan's +6 deviation: Rose from 0 to 6 over the week with no new conflict, governance, or market events identified. Treating as statistical noise until confirmation.
• Ethiopia-Eritrea war framing: Crisis Group's headline asks if they're close to all-out war. We see the report but no troop movements, border incidents, or OONI signal to corroborate escalation imminence.
• Seismic cluster near Panama: Three M4.0+ earthquakes flagged as elevated aftershock risk. No population displacement or infrastructure damage reported. Monitoring only.

🔭 The Week Ahead

Monday-Tuesday: Watch for Iran sanctions implementation — whether European or Asian banks adjust correspondent relationships. FX volatility in Morocco (our 38% call resolves Oct 30).

Wednesday: IMF releases quarterly outlook — watch for sovereign debt commentary on Pakistan, Ethiopia, and Morocco.

Thursday-Friday: OONI weekly data refresh. If Russian or Iranian blocking totals drop below 30,000 combined, that's a signal worth explaining. If they rise above 50,000 combined, we're calling it pre-positioning.

All week: Ethiopia border monitoring. Crisis Group flagged escalation risk; we need open-source troop movement confirmation or cross-border incident reports before calling it live. ACLED would be the first to publish if it happens.

Saturday wrap: 27 countries above CII 50 — watch for any unexpected deviation spikes in the tier-two risk band (CII 60-70). Venezuela, Pakistan, and Ethiopia all sit there with recent volatility.
