Geopolitical tensions around Iran and the Strait of Hormuz are the dominant market driver on Thursday, August 13, 2026, with implications for energy prices, global supply chains, and risk sentiment. Oil has slipped below $90 despite supply disruptions, while US refiners are posting strong profits. Treasury yields dipped ahead of wholesale inflation data as markets weigh stagflation risks from energy shocks against cooling demand signals.
Iran, US make competing claims over control of Strait of Hormuz – Reuters
Source: Reuters · Read original →
Direct assertions by Iran and the US over control of the critical Strait of Hormuz—through which roughly one-third of global seaborne oil passes—signal escalating geopolitical brinkmanship that threatens to disrupt crude supply at any moment. This dispute represents the core flashpoint of the broader US-Iran conflict and creates binary tail risk for energy markets. Control of the Strait determines both physical supply flows and the premium investors demand for crude.
Market implication: Equity volatility likely to spike on any Strait closure headlines; oil supply shock could drive rapid repricing across energy, financials, and defensives.
Are global oil stocks big enough to weather another six months of US-Iran war? – Reuters

Global strategic petroleum reserves and commercial stocks are being tested by the prospect of a prolonged conflict; the question of whether these buffers can absorb six months of additional supply losses is now a critical market focal point. Unlike short-term disruptions, extended conflict would deplete reserves and force demand destruction or shift supply from other sources. This is a duration-and-magnitude question that directly determines whether the current $90/barrel oil level holds or shatters higher.
Market implication: If reserve adequacy is questioned, oil could spike 15–25% within days; refined products margins (tracked by refiners like PSX, VLO, MPC) would expand sharply.
Top US refiners see profits soar, step up investor rewards – Reuters

US refiners are capturing exceptional margins as the refining spread widens—a direct result of crude supply anxiety and Middle East premium building into the crude curve. Refiner profitability is now a leading indicator of sustained energy market stress; expanding cash flows are enabling record shareholder returns and signaling confidence in high margins persisting. This is a direct beneficiary trade from the Iran conflict.
Market implication: Refiner equities (PSX, VLO, MPC) are outperformers in a conflict scenario; energy sector relative strength versus broad market likely to persist if Strait tensions escalate.
Oil slips on weaker demand outlook and higher US stocks amid supply disruptions – Reuters
Source: Reuters · Read original →
Oil’s retreat below $90 despite supply disruption risks reflects a battle between supply-shock dynamics and demand-destruction fears; weaker demand outlook and building US inventory cushion are offsetting geopolitical premium. This bifurcation—supply risk versus demand weakness—suggests the market is pricing in either a brief, limited conflict or that growth fears are overriding energy anxiety. The balance between these forces is fragile.
Market implication: Oil volatility likely to remain extreme; break of $90 support could signal demand-destruction dominance, pressuring energy stocks and supporting defensive equities and bonds.
Treasury yields dip as Wall Street awaits wholesale inflation data
Source: CNBC · Read original →
The 10-year Treasury yield fell to 4.674% as markets await wholesale (PPI) inflation data—a key test of whether energy shocks are translating into persistent core inflation or being contained by demand softness. This yield dip signals flight-to-safety positioning and suggests traders are hedging both stagflation risk (energy shock) and growth risk (Iran conflict impacts global demand). The data print today will be critical for rate expectations.
Market implication: If PPI comes in hot, yields spike and equities sell off; if tame, yields stay anchored and risk assets stabilize—10-year movements will likely exceed 5 bps intraday.
The Iran war risks bringing the G7’s fastest-growing economy to a halt
Source: CNBC · Read original →
The UK, recently the fastest-growing G7 economy, faces acute downside risk from prolonged Iran conflict and elevated energy prices, which threaten to reverse recent momentum and stall growth. High energy costs would hit UK consumers and businesses hard, especially given limited domestic energy production and prior inflation trauma; this creates a policy bind for the BoE between supporting growth and fighting inflation. UK economic exceptionalism is now contingent on swift de-escalation.
Market implication: GBP weakness likely if Iran conflict extends; FTSE underperformance versus US equities probable; BoE rate cut odds could rise if growth concerns mount.
US budget deficit widens in July on higher outlays, negative tariff receipts – Reuters
Source: Reuters · Read original →
The US budget deficit expanded in July due to higher outlays and negative tariff receipts—signaling that recent tariff policy is not delivering expected revenue and may instead be creating fiscal drag as import collections fall short. This structural widening of the deficit, now occurring against a backdrop of elevated debt levels and rate pressure, limits fiscal flexibility for policymakers if growth stalls from Iran conflict. Higher deficits also put upward pressure on longer-term rates.
Market implication: Longer-duration Treasuries face persistent supply pressure; deficit concerns could prevent yields from falling even if recession fears mount, creating a stagflation-biased policy environment.
