☕ Good Morning

The Ledger — 36 resolved today, 10 hit · OONI Brier 0.077 over 67, skill withheld (2 of 3 batches) · FX Brier 0.043 over 3, skill withheld (1 of 3 batches) · 1218 open, next resolves 2026-09-05

Happy Sunday. This was a week of political crackdowns measured in thousands of network blocks, record-setting sanctions against Cuba, and volatility across the Korea peninsula. Russia and Iran just posted their highest 7-day censorship counts we've measured — 2,346 and 1,019 confirmed blocks respectively. Meanwhile, our calls closed the week 20-for-70: cheap hits on the usual suspects, expensive misses on Bangladesh and Uzbekistan where we called censorship that never materialized.

🎯 This Week's Calls

70 calls settled against external ground truth: 20 hit, 50 miss. 74 due calls remain pending under the coverage-grace rule (thin evidence, never scored as a miss).

Thailand — HIT. We said 52% (base rate 70%) for a confirmed censorship event by 2026-09-05. OONI confirmed blocking on 3 days in the window. We beat the base rate on a country that doesn't always cooperate with pattern.

Bangladesh — MISS. We said 32% (base rate 50%) for a confirmed censorship event by 2026-09-05. OONI recorded nothing. We got confident on thin signal and paid for it.

Uzbekistan — MISS. We said 52% (base rate 40%) for a confirmed censorship event by 2026-09-05. No blocks confirmed. Another confident call on a low-visibility environment where we should have stayed closer to the prior.

Most divergent open call: Sweden (SE) — 18% chance the currency depreciates ≥1.92% peak-vs-issue by 2026-09-10, 10 points under its 28% base rate. Resolves Wednesday.

📍 The Week That Was

1. Russia and Iran set 7-day censorship records

OONI recorded 2,346 confirmed blocking measurements in Russia and 1,019 in Iran over the last seven days — the highest weekly counts for both countries since we began logging in April. Turkey added 160, India 67. No major protest cycle, no election, no obvious external trigger. This looks like baseline repression infrastructure running hot.

1. US designates Cuban state oil infrastructure

OFAC added six Cuban entities to the SDN list on September 3rd under EO14404: Banco Exterior de Cuba, two petroleum import companies, a nickel supply firm, and a services entity. Fidel Ernesto Castro Calis also designated. This is the most comprehensive Cuba sanctions package since the executive order was signed, targeting the entire upstream fuel supply chain.

1. US and Iran exchange maritime strikes

BBC reports US and Iranian forces traded retaliatory attacks on ships this week. No vessel names, no casualty counts, no date precision in the wire copy. Crude oil (USO) closed the week flat at $141.96, down 0.09%. If Hormuz risk were repricing, energy majors would know.

1. Sudan hit +6 deviation with no identified driver

Sudan's live deviation jumped to +6 this week on top of an 89 structural level. We have no OONI data, no sanctions change, no wire explanation in the context. The number moved; we don't know why.

1. North Korea deviation spiked to +8 on Thursday

North Korea's live score hit 8 on 2026-09-05 before settling back to 2.4 today. No seismic event, no missile test in the context, no KCNA framing. South Korea moved +7 in the same window. Something happened on the peninsula; the data doesn't tell us what.

1. Yemen records a Palestinian-style volatility signature

Palestine's CII spiked to 6.9 on September 3rd, then zeroed out. Yemen, Syria, Somalia, South Sudan, Afghanistan, Ukraine — all flatlined at structural level with zero deviation all week. Yemen's stability at 92 is the outlier, not Palestine's twitch.

1. Egypt sentences 12 to death in drugs case, including a TV presenter

BBC reports an Egyptian court handed down death sentences to 12 defendants in a narcotics case, one of them a television presenter. No date, no court name, no defendant names beyond the occupation. Egypt's CII is 59 with zero deviation — high structural risk, no live signal.

🌍 The Board: Weekly View

Movers

South Korea 13 (▲+7) — driver not identified in this week's data. Sudan 89 (▲+6) — driver not identified in this week's data. North Korea 81 (▲+2.4) — single-day spike to +8 on 2026-09-05, cause unidentified. Iran 85 (▼-2) — network interference at 1,019 confirmed blocks over 7 days, but deviation drifted from 20 to 18. Kenya 36 (▼-6) — deviation returned to zero from +6 with no explanation in context. Japan 8 (▼-5) — deviation returned to zero from +5 with no explanation in context.

Markets

Energy flat despite Hormuz headlines. Crude oil ETF (USO) $141.96 (-0.09%), natural gas ETF (UNG) $10.56 (+0.67%), energy sector ETF (XLE) $64.06 (-0.87%). Treasury bond ETF (TLT) up 0.17% to $82.21 — modest haven bid. Gold ETF (GLD) down 0.84% to $406.77. Dollar index ETF (UUP) up 0.25% to $28.08. S&P 500 ETF (SPY) down 0.39% to $770.19.

What would change our mind: A confirmed GPS jamming event in the Korea Strait logged by commercial航空 or maritime AIS, or a currency move in KRW exceeding 2% intraday — both would confirm the North Korea spike as operational, not data noise.

🙊 What We're Not Saying

• We are NOT explaining Sudan's +6 or South Korea's +7 — no driver is identified in the data we logged.
• [BBC World] reports "US and Iran trade retaliatory attacks on ships"; nothing in the market data, OONI, or sanctions logs corroborates a material escalation. Oil is flat.
• North Korea's Thursday spike to +8 has no support in seismic logs, no KCNA statement in the feed, no OONI measurement. We logged the number; we cannot explain it.
• The Palestine CII spike to 6.9 on September 3rd came with no wire story, no OONI event, no conflict headline in the GDELT feed (which is unavailable this cycle). Single-day volatility with no cause in the context.

🔭 The Week Ahead

• Sweden currency call resolves Wednesday, September 10th — 18% chance of ≥1.92% depreciation. We're 10 points under the base rate; watch SEK for repricing.
• Russia and Iran censorship trajectories — both countries just set records. OONI updates daily. If blocking counts sustain above 1,500/week (Russia) or 800/week (Iran), we're looking at a new baseline, not a pulse.
• Cuba sanctions implementation — six Cuban entities hit the SDN list this week. Watch for secondary sanctions on non-US counterparties and any retaliatory measures from Havana.
• Korea peninsula — North Korea and South Korea both spiked this week with no identified cause. Monitor for missile tests, joint military exercises, or KCNA statements that would explain the move.
• Hormuz shipping — BBC reported US-Iran maritime exchanges. If this is real, watch for Lloyd's List reporting, AIS gaps in the Strait, or a sustained move in Brent futures. None of that has happened yet.
• Sudan — sitting at 89 structural with a +6 deviation and no explanation. Any ACLED update, sanctions change, or RSF/SAF territorial reporting would clarify.
