Brent Drops Below $106 on Strike Pause; Iran Threatens Mines

Osomon Consultancy LLC-FZ | Monday, 23 March 2026 | 14:04 GMT

As flagged in the morning breaking update, Trump postponed strikes on Iranian power and energy infrastructure for five days, citing productive conversations. Since then, Iranian state media, including semi-official Mehr News Agency, has denied any dialogue and framed the pause as a retreat 'out of fear of Iran's response,' CBS News and Al Jazeera reported. No formal Iranian governmental acknowledgement of a communication channel has been issued.

Israel launched what it described as a second round of strikes on infrastructure targets in Tehran on Monday, hours after what the IDF called a 'wide-scale wave of strikes,' Al Jazeera reported. Al Jazeera Arabic's Tehran correspondent described explosions of 'unprecedented' size, particularly in eastern Tehran. Separately, Fars News, affiliated with the IRGC, reported a strike on a residential building in Khorramabad killed one child, and at least 6 people were killed in strikes on homes in Tabriz. → Wider war

Israeli warplanes conducted precision strikes in Gilan and Mazandaran provinces in northern Iran that appeared to target officials, Al Jazeera reported. These strikes occurred alongside continued operations in Isfahan, expanding the geographic scope of Israeli targeting beyond Tehran and known nuclear or military sites. → Wider war

US CENTCOM stated it has struck more than 7,000 targets in Iran since 28 February, Al Jazeera reported. Trump's five-day pause applies specifically to power plants and energy infrastructure; conventional military strikes are continuing. → Quagmire

Al Jazeera's cumulative casualty tracker reports approximately 1,500 dead in Iran, at least 18 in Israel, 13 US soldiers, and 21 killed in Gulf states since the war began on 28 February. These are the first consolidated cross-theatre figures available. → Quagmire

Iranian missile strikes continued overnight into Monday, with shrapnel reported across southern and central Israel. A joint Hezbollah-Iran attack targeted northern Israel, Al Jazeera reported, marking the first confirmed coordinated strike between the two forces since the war's current phase began. → Wider war

Iran's Defense Council warned that any attack on Iran's coastline would trigger mine-laying across Gulf sea lanes, NPR reported. Separately, IRGC-affiliated Mehr News released a map identifying regional power plants as potential retaliatory targets, Al Jazeera reported. → Wider war

Strait of Hormuz traffic has plunged more than 95 per cent since the war began, according to data from Windward, a maritime analytics firm, cited by Al Jazeera. This quantifies the near-total commercial shutdown previously described qualitatively. → Wider war

Omani Foreign Minister Albusaidi said Oman is 'working intensively' for safe passage arrangements through the Strait of Hormuz, CNN reported. Oman, which borders the strait's southern shore and has historically served as a back-channel between Iran and the West, is the first regional state to announce active mediation on the transit question. → Off-ramp

Saudi Foreign Minister warned that 'nonpolitical' options are on the table if Iran continues attacks on the Kingdom, Al Jazeera reported. This follows Saturday's interception of ballistic missiles targeting Riyadh, covered in the previous daily edition. → Wider war

Israel struck a critical bridge over the Litani River in southern Lebanon on Sunday, CNN reported. Lebanese President Aoun condemned strikes on infrastructure and offered direct negotiations with Israel, CBS News reported. → Quagmire

NATO Secretary General Rutte said he is 'absolutely convinced' the alliance will be able to reopen the Strait of Hormuz, CNN reported. Trump separately branded NATO allies 'cowards' for refusing military assistance, Al Jazeera reported. → Quagmire

UK Prime Minister Starmer said he does 'not believe in regime change from the skies,' though the UK has continued allowing US use of military bases for strikes on Iranian missile sites, Al Jazeera and the House of Commons Library reported. → Quagmire

Republican Senator Lisa Murkowski said she is considering pushing for a congressional vote to authorise the war if Trump deploys ground troops to Iran, CNN reported, the first Republican senator to break with the administration on authorisation since the War Powers resolutions were defeated last week. → Quagmire

The five-day pause announced on Trump's Truth Social account is doing exactly what the breaking update predicted: buying time without changing any underlying condition. Brent's 6 per cent drop is the market pricing the deferred trigger, not a resolution. The selective Hormuz blockade remains operational, traffic through the strait is down 95 per cent, and the IRGC has not loosened a single transit restriction. What the market is actually pricing is five days without strikes on Iranian power plants, a bet that the narrowest possible interpretation of the pause will hold while 7,000-plus conventional strikes continue across Iranian territory.



Iran's framing of the pause matters more than the pause itself. Tehran's decision to claim Trump retreated 'out of fear' while simultaneously denying any dialogue exists creates a domestic political trap: Iranian leaders who have told their public they forced America to back down cannot then make concessions on Hormuz without appearing to have lied. This is the inverse of the problem Trump created for himself with the ultimatum. Both leaders are now boxed in by their own public narratives, which is precisely how five-day pauses become permanent stalemates or collapse into escalation.



The mine-laying threat from Iran's Defense Council is the most consequential signal since the selective blockade began. Mines are qualitatively different from naval patrols or IRGC vetting systems. They persist after ceasefires, they cannot be selectively applied to specific flag states, and their clearance takes months. If Iran begins laying mines, the selective blockade framework, which at least preserved the theoretical possibility of resumed transit, gives way to physical denial of the waterway. The IRGC-affiliated publication of regional power plant targeting maps serves the same function: demonstrating that Iran's retaliatory menu extends well beyond Hormuz and includes the energy infrastructure of states that have not joined the war.



Oman's entry as an active mediator on safe passage is the most constructive development of the past 48 hours. Muscat brokered the 2015 preliminary nuclear talks and maintained diplomatic relations with Iran throughout the maximum-pressure era. If any regional capital can negotiate a partial reopening of Hormuz, it is Oman. The question is whether five days is sufficient for Omani mediation to produce anything tangible, or whether the window is consumed by the same mutual posturing that has characterised every diplomatic interaction since 28 February.



The cumulative toll now visible in Al Jazeera's tracker, 1,500 dead in Iran, 13 US soldiers, 21 in Gulf states, establishes the human scale of a conflict that markets have been pricing primarily through energy futures. Thirteen American military deaths with no congressional authorisation and roughly one in four domestic approval is a political fact that has not yet found institutional expression, but Senator Murkowski's conditional break with the administration on authorisation is the first crack. The five-day window is not just about Hormuz; it is about whether the political sustainability of the campaign outlasts the military momentum.

Ceasefire, oil drops to $70-80, LNG normalises. Fed cuts resume. EUR rebounds harder than GBP. Dollar weakens. Gold retreats. Equities rally.

Today: Raised from 13 per cent. Omani mediation on Hormuz safe passage adds a credible intermediary alongside whatever US-Iran channel exists; Oman's track record as an Iran back-channel is the strongest of any regional actor.

War drags, dollar peaks Q2 then fades on US recession risk. GBP outperforms EUR (BoE can hike, ECB trapped). Oil $90-110, LNG elevated. Gold grinds higher. Equities choppy.

Today: Raised from 44 per cent. The five-day pause on energy infrastructure while conventional strikes continue at 7,000-plus targets creates the defining quagmire pattern: intense military action without political resolution or further escalation thresholds being crossed.

Regional escalation, Hormuz stays closed, $130+ oil, LNG spikes to $20-28. Dollar strong throughout. EUR collapses more than GBP. Gold surges. Equities enter bear market.

Today: Cut from 43 per cent. The immediate escalation trigger has been deferred and the Omani mediation channel offers a route to partial Hormuz reopening; however, the mine-laying threat and IRGC targeting maps of regional power plants keep the probability elevated well above baseline.

USD

DXY eased to 99.5 from 100 as the pause announcement marginally reduced the safe-haven bid. The dollar's trajectory for the next five days depends entirely on whether the pause leads to tangible concessions on Hormuz or collapses. Near-term range narrows to 98 to 101.

EUR

EUR/USD firmed modestly to approximately 1.088 from 1.085, consistent with the reduced immediate escalation premium. The structural headwind from Ras Laffan's five-year repair timeline and Hormuz near-closure remains the dominant medium-term factor; any relief rally in the euro is capped until either LNG supply or transit normalises.

GBP

GBP/USD essentially flat at 1.334. Starmer's rhetorical distancing from the campaign while maintaining base access preserves sterling's relative positioning. The BoE's optionality to hike if energy costs feed through continues to underpin GBP versus EUR.

USD earners in Europe

As flagged in the breaking update, the crisis urgency for accelerating EUR conversions has eased. Continue converting on schedule at 1.088, which remains elevated purchasing power by pre-war standards. If the five-day window produces tangible Hormuz progress, EUR will firm further and the conversion window narrows; if it collapses, the crisis premium returns and EUR weakens again. The asymmetry still favours converting now rather than waiting.

EUR earners

Unchanged from yesterday. Avoid converting to USD at these levels. The dollar's crisis premium will partially unwind under any sustained de-escalation, and the five-day window tilts the near-term odds toward that partial unwind.

GBP earners

Unchanged from yesterday. Sterling's relative resilience holds at 1.334. Cross-rate dynamics continue to favour GBP holders with euro-denominated expenses.

Any change in Hormuz transit conditions during the five-day window: loosening of IRGC vetting requirements, additional country-specific exemptions beyond Japan, or resumption of tanker traffic would be the first tangible concession and would push off-ramp probability above 20 per cent.

Iranian governmental statement confirming or denying a communication channel with the US; the current asymmetry where Trump claims talks and Tehran denies them is unstable and its resolution determines whether the off-ramp or wider war probability moves next.

IAEA assessment of Natanz enrichment facility damage and any statement on the status of enrichment operations; the nuclear dimension remains unresolved since US-Israeli strikes reported 21 March.

Any evidence of Iranian mine-laying operations in Gulf sea lanes; the Defense Council's threat converts from signalling to operational reality the moment mines are deployed, and would immediately reverse the oil decline and push wider war probability back above 45 per cent.
