As the ongoing Israel-Iran conflict intensifies geopolitical risks, London’s FTSE 100 posted modest gains while Brent crude oil prices steadied near $75 a barrel. Rising insurance costs for vessels navigating the Strait of Hormuz reflect mounting maritime concerns, even as key oil export routes remain operational and central banks weigh inflation and interest rates.
London’s FTSE 100 saw modest gains amid heightened Middle East tensions, with investors closely eyeing inflation data and upcoming central bank rate decisions. The index closed slightly up at 8,843.47 points as markets remained cautious but resilient amid the sixth day of conflict between Israel and Iran. Brent crude oil prices fluctuated, dipping to just above $75 a barrel after earlier trading above $77, reflecting concerns over potential disruptions in the critical Strait of Hormuz, a passage for around one fifth of global oil shipments.
Iran’s Supreme Leader, Ayatollah Ali Khamenei, firmly rejected calls from US President Donald Trump for an “unconditional surrender,” warning of “irreparable damage” if the US initiates military action. Mr Trump indicated indecision on involvement, stating he was “considering” joining Israeli strikes but also mentioning that Iran sought negotiations to end hostilities. This standoff has intensified regional risks, with shipping markets signalling increased anxiety. Very Large Crude Carrier (VLCC) rates for oil transport from the Middle East to China surged by around 40% since mid-June, mirroring a heightened risk premium as buyers diversify supplies away from Gulf waters. Moreover, Qatar has imposed restrictions on tanker movements near the Strait, and several shipping companies have advised vessels to reroute closer to Oman’s coast to mitigate risks amid rising incidents of electronic navigation interference and a recent collision between oil tankers in the area.
Despite the tension, key infrastructures such as the Strait of Hormuz and Kharg Island remain operational. Market participants have shown a muted reaction compared to past geopolitical crises like Russia’s invasion of Ukraine. Analysts attribute this to the United States’ position as a leading oil and gas producer, reducing dependence on Middle Eastern supply, and continued Iranian oil exports. However, markets are watchful of “tail risks,” including possible attacks on export terminals or shut-downs of the Strait that could sharply escalate oil prices. The relatively stable price of Brent crude at around $75-$76 per barrel suggests the oil market currently does not anticipate a severe supply shock. The CEO of Italy’s Eni emphasised that while Iran has historically threatened to close the Strait, such a move would backfire economically and provoke a swift response, making an actual closure unlikely.
Meanwhile, insurance premiums for vessels navigating the Strait of Hormuz have soared by over 60%, reflecting escalating conflict risks. Coverage costs for hull and machinery insurance on high-value ships have risen substantially due to threats from Iranian-backed Houthi rebel attacks, electronic signal interference, and the potential for military escalation. Some insurers are reconsidering coverage, while others are capitalising on increased premiums, signalling heightened caution in maritime operations through this strategic oil route.
Parallel to these geopolitical strains, economic data has provided further context for market movements. UK inflation numbers aligned with expectations, with Consumer Prices Index rising 3.4% annually in May, a slight slowdown from April. Core inflation also eased modestly, driven by slowing services inflation, despite persistent food price pressures. Barclays notes the Bank of England’s Monetary Policy Committee may feel reassured by these underlying trends but remains cautious due to ongoing commodity price volatility. The Bank of England is widely expected to maintain interest rates at 4.25%, mirroring anticipated Federal Reserve decisions later in the day to hold rates steady at 4.25%-4.50%. Employment data in the US indicates some softening in the labour market, yet inflation risks persist, suggesting central banks are unlikely to pivot to rate cuts imminently.
European markets showed mixed responses, with Paris and Frankfurt indices dipping slightly, while US stocks closed higher. Currency markets were relatively stable but showed minor fluctuations in the pound, euro, and yen against the dollar. Meanwhile, gold prices edged upwards, signalling investors’ continued appetite for safe-haven assets amid geopolitical uncertainties.
Corporate news on London’s stock exchanges brought some bright spots amid the cautious sentiment. Melrose Industries surged following positive outlooks linked to defence sector opportunities highlighted at the Paris Air Show, while Rathbones Group received an upgraded “buy” rating buoyed by strategic acquisitions. Conversely, stocks such as Howden Joinery faced downward pressure due to anticipated underwhelming financial performance.
As the global spotlight remains on the unfolding Middle East conflict, its ripple effects on inflation, central bank policies, energy markets, and maritime safety continue to present a complex landscape for investors and policymakers alike.

- https://www.reuters.com/markets/commodities/oil-tanker-market-signals-more-middle-east-energy-disruption-ahead-2025-06-18/ – The oil tanker market is signalling increased risk and potential energy disruptions in the Middle East amidst escalating tensions between Israel and Iran. Following Israel’s recent bombardment of Iran and Tehran’s retaliatory missile strikes, Brent crude oil prices surged around 8% to $75 per barrel. Although the broader market appears cautiously stable, oil shipping data suggests rising anxiety. Daily rates for Very Large Crude Carriers (VLCCs) transporting oil from the Middle East to China have jumped 40% since June 13, signalling a higher risk premium. Similar rate increases are seen on West Africa-China routes, reflecting efforts by buyers to diversify away from the Middle East. Qatar has also imposed shipping restrictions near the Strait of Hormuz. Although no physical attacks have occurred there, a tanker collision and increased electronic interference with ship navigation systems are raising operational concerns. Over 260 ships recently reported GPS spoofing near Iran’s South Pars Power Plant. These developments hint at potentially severe implications for global energy supply routes, despite the absence of direct hostilities in Hormuz. The oil tanker market, therefore, serves as a crucial barometer for assessing real-time geopolitical risk in the region.
- https://www.ft.com/content/06c545ca-c3a3-4014-a358-f57136187617 – In this episode of the Unhedged podcast, Katie Martin and Robert Armstrong discuss the market implications of the escalating conflict between Israel and Iran. Despite rockets exchanged and rising tensions, oil prices have seen only modest fluctuations, currently trading around $73 per barrel. This is notably lower than spikes witnessed during past geopolitical crises, like Russia’s invasion of Ukraine. The relatively muted reaction is attributed to the U.S. becoming the top global oil and natural gas producer, reducing reliance on Middle Eastern supply. Additionally, Iran continues to export oil, and key infrastructure like Kharg Island and the Strait of Hormuz remains operational, indicating the conflict hasn’t yet reached a critical economic disruption point. However, markets remain vigilant for potential “tail risks,” where scenarios like attacks on export facilities or Strait closures could significantly spike oil prices. Other indicators, such as gold nearing record highs and shifts away from the U.S. dollar, signal some market unrest. The discussion highlights investor uncertainty and challenges central banks, especially the U.S. Federal Reserve, may face if the conflict intensifies and impacts inflation. Despite the gravity of the geopolitical situation, the markets so far remain resilient.
- https://www.reuters.com/world/middle-east/ships-advised-keep-their-distance-iran-around-hormuz-strait-2025-06-18/ – Commercial shipping vessels are being advised to avoid Iranian waters near the Strait of Hormuz due to escalating conflict between Iran and Israel. Ships are rerouting closer to the coast of Oman to reduce risks. The Strait of Hormuz is a strategic chokepoint for global oil shipments, and any disruption could impact global oil trade and prices. Iran previously threatened to close the strait in retaliation for Western actions, raising concerns over maritime safety. Incidents of navigation interference have increased, and Greek authorities have warned their vessels to steer clear of Iranian territorial waters. Iran’s Supreme Leader Ayatollah Ali Khamenei has rejected U.S. calls for surrender amidst ongoing hostilities. The rising conflict and electronic interference have heightened regional maritime threats, prompting companies like QatarEnergy to delay tanker entries into the Gulf until immediately prior to cargo loading. Supertanker earnings have also surged, reflecting the increasing risks associated with navigating this vital region.
- https://www.reuters.com/world/middle-east/iran-israel-trade-accusations-un-shipping-agency-over-sea-lanes-2025-06-18/ – At a session of the International Maritime Organization (IMO) on June 18, 2025, Iran and Israel exchanged sharp accusations over maritime security in the Gulf and Red Sea amid escalating military tensions. Iran charged Israel with attacking petrochemical and gas infrastructure in Asalouyeh, endangering global maritime security and international energy supplies. Iran warned of potential sea conflict if the global community failed to act and reiterated threats to close the critical Strait of Hormuz. Maritime agencies are advising vessels to avoid Iranian waters as a precaution. Meanwhile, Israel accused Iran of endangering international sea lanes by supporting Yemen’s Houthi rebels, who have disrupted Red Sea and Suez Canal shipping. Israel alleged Iran turned the region into a conflict zone, enabling maritime terrorism. The IMO, which governs global shipping safety, noted the statements but faces criticism for becoming politicized, as shown by past rejections of Iranian maritime event proposals and previous political tensions involving Russia.
- https://www.ft.com/content/fa7dac93-8b4b-45d3-80f5-5ddd527a0d70 – Insurance premiums for ships navigating the Strait of Hormuz have surged over 60% due to escalating conflict between Israel and Iran, raising fears about shipping safety in this strategic oil transit route. The cost of hull and machinery insurance—covering damage to the ship itself—has increased from 0.125% to 0.2% of a vessel’s value, elevating coverage for a $100 million vessel from $125,000 to $200,000. The heightened risk is attributed to potential threats from Iranian-backed Houthi rebel attacks, electronic interference, and broader military escalation. A recent collision between oil tankers near the strait involving irregular navigational signals has further stoked insurer concerns. Marsh McLennan’s global head of marine and cargo, Marcus Baker, noted that although no direct missile attacks have occurred, market anxiety remains high. Some insurers may withdraw coverage due to the risks, while others might capitalize on the higher premiums. Cargo insurance rates are also expected to increase, albeit more gradually.
- https://www.reuters.com/business/energy/oil-markets-see-closure-hormuz-strait-unlikely-eni-ceo-says-2025-06-18/ – Eni CEO Claudio Descalzi stated that oil markets do not anticipate the closure of the Strait of Hormuz, despite escalating tensions between Israel and Iran. The continued stability of crude oil prices, remaining below $80–$90 per barrel, suggests the market does not foresee extreme disruptions. The Strait of Hormuz is critical to global oil flows, with about 20% of global oil passing through it. Israel recently launched strikes on June 13 targeting Iranian military and nuclear facilities, although Iran denies it aims to develop atomic weapons. Historically, Iran has threatened to close the Strait in response to Western actions, but Descalzi noted such a move would harm Iran’s own oil exports and prompt U.S. intervention. He believes global leaders will strive to avoid such escalation. Separately, Eni continues to shift its business focus toward renewables, expecting to raise €2 billion from the planned sale of a 20% stake in its renewable unit Plenitude, with exclusive talks underway with Ares Alternative Credit Management. As of Wednesday, oil prices held steady, with Brent crude at approximately $76.6 per barrel.
