Brent crude futures settlement on 2026-08-20 exceeds the Aug 19 close by 2% or more on oilprice.com.

Elevated regional tensions from Houthi blockade and Hormuz uncertainty per packet sources create conditions for modest price upside in near term.

How this resolves

The percentage difference between the two daily settlement prices published on the Brent futures page must be +2% or higher for Hit. Data must be available by 2026-08-21 00:00 UTC.

Frozen inputs: Oilprice.com: Brent Crude Futures

Grade: Brent rose sharply on 2026-08-20 as Hormuz traffic stalled and Trump's 'economic D-Day' campaign pushed prices higher. Forbes/Fortune reported Brent futures +3.29% over the prior 24h to ~$94.57 as of Aug 20, comfortably above the +2% threshold. Minor discount for exact settlement-source/timing ambiguity across benchmarks. · Brier 0.2704

Global Health27%

WHO reports at least 500 new Ebola cases or confirms PHEIC extension with vaccination timeline in DRC update by 2026-08-20.

Emergency committee met recently with active PHEIC and high death toll, but daily case growth and rollout timing remain uncertain per available sources.

How this resolves

Official WHO situation report or Al Jazeera coverage dated 2026-08-20 must document the new case threshold or explicit vaccination schedule.

Frozen inputs: WHO: Ebola outbreak — DRC 2026 · Al Jazeera: WHO Emergency Committee DRC Ebola Aug 18

Grade: ECDC reported 5,290 cumulative confirmed DRC Ebola cases (2,516 deaths) as of data through Aug 19, up from ~4,000 on Aug 7 — an average of roughly 100-110 new cases/day, far below the 500-new-cases-in-a-day threshold. No WHO PHEIC extension with an explicit vaccination timeline was announced on 2026-08-20. · Brier 0.0361

Saudi war cabinet or military issues public authorization for expanded operations against Houthi forces following the Najran attack by 2026-08-20.

Packet explicitly notes Saudi war cabinet Tuesday authorization and military response options under active consideration amid ongoing exchanges.

How this resolves

Al Jazeera or Reuters reports an official Saudi authorization or rules of engagement update dated 2026-08-19 or 2026-08-20.

Frozen inputs: Reuters: Saudi War Cabinet Tuesday authorization · Al Jazeera: Saudi Arabia Mecca agreement military response options

Grade: Houthis struck Najran airport and Aramco facilities again on Aug 20, and Saudi Arabia issued a formal warning that repeated vessel attacks are a 'dangerous escalation' under international law, but no public Saudi war-cabinet authorization for expanded operations or rules-of-engagement update was reported by Reuters/Al Jazeera on Aug 19-20.

Middle East / US Foreign Policy15%

Iranian Foreign Minister Araghchi or Omani mediators announce a breakthrough or extension of Hormuz talks with US involvement by 2026-08-20.

Last-chance talks underway after Aug 17 expiry, but IRGC entrenched position and market skepticism at 38% for interim by month-end indicate low odds of quick public win.

How this resolves

Credible reporting from Reuters, Al Jazeera, or Times of Israel on or before 2026-08-20 confirms any public statement of progress or new deadline.

Frozen inputs: Reuters: Iran ceasefire expired; Araghchi Oman talks · Times of Israel: IRGC Mohebi Hormuz statement

Grade: The US-Iran deadline expired Aug 17 with no deal; by Aug 20-21 Trump declared an 'economic D-Day' and the Oman back-channel was paused rather than extended. Iran's lead negotiator Ghalibaf spoke of planning to overcome sanctions, signalling breakdown, not a breakthrough or a publicly announced extension with US involvement. · Brier 0.0025

Colombian finance ministry or quake relief authority publishes a detailed $10 billion reconstruction financing plan or bond issuance schedule by 2026-08-20.

The $10B bill is noted as imperiling austerity with $1.3B credit secured, but full plan details and additional instruments likely require more time to draft and approve.

How this resolves

Bloomberg or Reuters article dated 2026-08-20 references the official plan release or specific financing instrument launch.

Frozen inputs: Bloomberg: Colombia $10 Billion Earthquake Bill

Grade: Damage was estimated at ~$9.6B (BTG Pactual/Bloomberg) and President de la Espriella floated a 'Plan Marshall' rhetorically on Aug 14, but no detailed finance-ministry reconstruction financing plan or specific bond-issuance schedule was published or reported by Bloomberg/Reuters by 2026-08-20. · Brier 0.0081

Russian forces conduct a follow-on drone or missile strike on Ukrainian civilian infrastructure or Chernihiv region within 48 hours of the Aug 17 attack, reported by 2026-08-20.

Recent 128-drone Chernihiv retaliation strike and NATO emergency session suggest continued escalation cycle before any diplomatic pause.

How this resolves

Kyiv Independent or Reuters confirms at least one new strike matching the pattern on or before 2026-08-20.

Frozen inputs: Kyiv Independent: Russia 128-drone Chernihiv strike · Reuters: NATO Brussels emergency session

Grade: Russia conducted a massive strike on Kyiv and other regions overnight into Thursday Aug 20, killing 17+ and hitting civilian infrastructure, with spillover into Romania and Moldova; Chernihiv was struck by jet-powered Shahed drones (reported Aug 19-20). Clearly matches the follow-on civilian-infrastructure/Chernihiv strike pattern. · Brier 0.3721

Brent crude experiences a single-day move of +1.8% or greater on 2026-08-21 tied to regional news.

Persistent Houthi activity and Hormuz uncertainty expected to sustain volatility into mid-week per the packet's escalation lineage.

WHO announces deployment of experimental vaccines or ring vaccination strategy to 10+ health zones in DRC by 2026-08-21.

Emergency committee active but full rollout details and scale of vaccination campaign rollout timeline uncertain from Aug 18 reporting.

Al Jazeera or WHO site update confirms the deployment announcement or zone count by end of 2026-08-21.

Frozen inputs: Al Jazeera: WHO Emergency Committee DRC Ebola Aug 18 · 2026 Central Africa Ebola epidemic — Wikipedia

Grade: The dominant DRC strain is Bundibugyo, for which WHO's Aug 20 outbreak page states there is no vaccine or specific treatment; an Ervebo (Zaire) Phase 3 trial was authorized but UN/WHO said results are months away. No WHO announcement of experimental-vaccine or ring-vaccination deployment to 10+ health zones was made by 2026-08-21. · Brier 0.0121

Houthi forces declare or enforce an expanded blockade affecting at least one additional category of vessel or port in the Red Sea by 2026-08-21.

Blockade already day 14 on Aug 17 with ongoing tanker strikes; momentum suggests further expansion before any Saudi counter.

How this resolves

Times of Israel or Al Jazeera reports an official Houthi declaration or verified incident expanding the blockade scope on 2026-08-20 or 2026-08-21.

Frozen inputs: Times of Israel: Houthi Bab al-Mandeb blockade

Grade: Houthi pressure continued (30+ claimed operations, additional Saudi Aramco/Jazan refinery drone strikes, ships warned off Saudi ports), but no Al Jazeera/Times of Israel report on Aug 20-21 documented an official declaration or verified incident expanding the existing Bab al-Mandeb blockade to a new vessel category or port.

US officials including Kushner or State Department issue a public statement on Iran policy or Oman talks progress by 2026-08-21.

Kushner noted as 'not showing interest' and Trump threats issued after deadline miss; further US signaling possible mid-week as Aug 22 approaches.

How this resolves

Any on-record comment or new US position reported in Fortune, Reuters, or Times of Israel by 2026-08-21 resolves the claim.

Frozen inputs: Fortune: Emerging deal to reopen Strait of Hormuz · Al Jazeera: Iran Oman US close to Hormuz deal

Grade: US officials made prominent on-record statements on Iran policy by Aug 21: President Trump declared an 'economic D-Day' threatening secondary sanctions on any country trading with Iran, and Treasury Secretary Bessent publicly warned that the US would put 'its full might and force' against violators.

The pledging conference for Colombia earthquake relief secures at least $3 billion in new commitments from international donors by 2026-08-21.

Active pledging conference underway with $1.3B already confirmed; momentum from $10B bill suggests additional large pledges likely within days.

Bloomberg or Reuters summary of the conference or donor pledges dated 2026-08-21 shows aggregate new pledges meeting or exceeding $3B.

Frozen inputs: Reuters: Colombia $1.3B CAF World Bank credit confirmed · Bloomberg: Colombia $10 Billion Earthquake Bill

Grade: The World Bank and partners pledged to help channel financing (Aug 14 statement) and multilateral/US support was flowing, but no formal international pledging conference securing at least $3B in new commitments was reported by Bloomberg/Reuters by 2026-08-21.

Brussels emergency session just concluded with outcomes published; follow-through actions or aid decisions typically follow within 48-72 hours.

How this resolves

Reuters or Kyiv Independent reports a new NATO commitment, session date, or aid figure tied to the Aug 17 events by 2026-08-21.

Frozen inputs: Reuters: NATO Brussels emergency session

Grade: After the Aug 20 strikes spilled into Romania and Moldova, NATO condemned Russia and scrambled fighters (Spanish F-18s from Poland/Romania), but no follow-up NATO emergency session date or new military aid package tied to the Romanian airspace incident was reported by Reuters/Kyiv Independent by 2026-08-21.

Brent crude futures show a net decline of 3% or more across the D+1 to D+3 window due to positive Hormuz developments by close on 2026-08-22.

If any interim framework emerges by the Aug 22 deadline, markets may price in reduced risk premium despite entrenched positions.

Frozen inputs: Oilprice.com: Brent Crude Futures · Trading Economics: Brent Crude

Grade: Brent rose net over the D+1 to D+3 window rather than falling. The Aug 19 close was ~$91.5 (Brent settled +3.29% to ~$94.57 on Aug 20 per the f001 sourcing); by 2026-08-22 Brent was ~$93.78 (Eastern Herald daily quote) and ~$92.20 on Aug 24 (TradingEconomics).

Saudi Arabia executes at least one airstrike or naval engagement against Houthi targets in Najran or Yemen in authorized response by 2026-08-22.

War cabinet authorization and response options documented; with blockade ongoing into weekend, military action becomes more probable by D+3.

How this resolves

In the window the Houthis struck Najran airport and Aramco facilities (Aug 20) and Saudi Arabia issued warnings; Saudi-led coalition airstrikes on Hodeidah are documented earlier (late July), not clearly within or attributable to this window.

An interim ceasefire arrangement for the Strait of Hormuz is announced or takes effect by the Aug 22 hard deadline as referenced in market notes.

Market prices 38% for interim by Aug 31 but notes Aug 22 hard deadline and sharp collapse risk; our assessment lower due to IRGC entrenchment and recent deadline failure.

Grade: No interim Strait of Hormuz ceasefire involving the US, Iran and Oman was signed or made operational by 2026-08-22. The Aug 17 deadline lapsed; the US-Iran track collapsed into Trump's 'economic D-Day' secondary-sanctions threat (Aug 20-21).

The World Bank's relevant disbursement was US$200M on Aug 13 (below $1B and pre-dating the forecast window); it launched a GRADE damage assessment but announced no >$1B new package by the deadline.

A Russia-Ukraine ceasefire agreement or mutual de-escalation framework is signed or publicly endorsed by both parties by 2026-08-22.

Market-implied probabilities for any 2026 ceasefire are 10-16%; near-term agreement by weekend deadline is assessed even lower given recent drone escalation and NATO session without immediate Kremlin reply.
