Strait of Hormuz standoff lifts Brent past $107 as Federal Reserve, ECB, BOJ decisions loom

Brent crude futures climbed more than 2% to a three-week high of $107.97 a barrel in early Asia trade on Monday, while United States stock futures slipped and the dollar firmed marginally, after a second round of United States-Iran peace talks collapsed over the weekend without producing an agreement to reopen the Strait of Hormuz. The setback unfolds as global markets brace for one of the most consequential weeks of the monetary policy calendar, with the Bank of Japan, the United States Federal Reserve, the Bank of Canada, the European Central Bank, and the Bank of England all scheduled to deliver rate decisions over the next four sessions.

S&P 500 futures eased by 0.3% in the early Singapore session, slipping back from the record closing high reached by United States equities at the end of last week. The euro weakened by 0.15% to $1.1706 against the dollar, while the Japanese yen drifted to 159.53 per dollar, both reflecting a modestly defensive bid for the United States currency amid renewed geopolitical uncertainty. The price action signals that a market which had begun to price in a measured ceasefire de-escalation is now being forced to reprice persistent supply risk through the world’s most strategically important energy chokepoint.

How did the cancellation of the Witkoff and Kushner mission to Islamabad alter the diplomatic trajectory?

United States President Donald Trump cancelled the planned visit by special envoy Steve Witkoff and senior adviser Jared Kushner to Islamabad on Saturday, after concluding that conditions did not warrant a second round of direct engagement with Iranian negotiators. The mission had been billed by the White House as a follow-up to the historic face-to-face talks held earlier in April, and its abandonment marks the first significant rupture in the diplomatic cadence since United States President Donald Trump indefinitely extended the April 7 ceasefire last week.

Speaking on Fox News programme The Sunday Briefing, United States President Donald Trump said the United States was no longer willing to dispatch personnel to the region and indicated that any further engagement would have to be initiated by Tehran. United States President Donald Trump emphasised that the contours of any agreement remained, in his framing, narrow and non-negotiable, centred on Iran foregoing the development of nuclear weapons. The president also defended the maritime pressure campaign, characterising the United States blockade of Iranian ports as highly effective in constraining Iran’s economic options.

The Islamic Republic of Iran rejected direct talks, reiterating that any negotiation must proceed through mediators. The Pakistani Government has continued to function as the primary intermediary, with Iranian Foreign Minister Abbas Araghchi making two visits to Islamabad inside forty-eight hours and meeting Pakistan Prime Minister Shehbaz Sharif, Foreign Minister Mohammad Ishaq Dar, and Pakistan Army Chief Field Marshal Asim Munir. Iranian Foreign Minister Abbas Araghchi also met Sultan Haitham bin Tariq of Oman in Muscat on Sunday before flying onward to Moscow for talks with senior Russian officials, with President Vladimir Putin expected to host him on Monday.

Why is the closure of the Strait of Hormuz now driving structural risk premia rather than tactical price moves?

The Strait of Hormuz, the narrow maritime corridor connecting the Persian Gulf to the Gulf of Oman, has remained substantially closed to commercial traffic since the war between the United States, Israel, and the Islamic Republic of Iran began on February 28 with joint United States-Israeli strikes on Iranian targets. Approximately one fifth of global crude oil and a comparable share of liquefied natural gas pass through the strait under normal conditions, alongside significant volumes of fertiliser feedstock, refined products, and chemical cargoes from Saudi Arabia, the United Arab Emirates, Kuwait, Qatar, Bahrain, and Iraq.

Ship-tracking data from maritime intelligence provider MarineTraffic indicates that only a handful of vessels have transited the waterway in recent days, a fraction of pre-war throughput. The Islamic Republic of Iran has restricted passage and is seeking, according to regional officials, to establish a toll mechanism for vessels transiting the strait, with Oman approached as a possible administrative partner. The United States has imposed a counter-blockade on Iranian ports, and United States President Donald Trump confirmed last week that the United States Navy is conducting mine-clearance operations in the waterway. The president also authorised United States naval forces to engage small craft suspected of laying additional mines.

Iran’s joint military command warned over the weekend that continued United States naval activity, which the Iranian command characterised as aggression, would draw a strong response. The exchange of threats, even within a formal ceasefire framework, has prevented the resumption of normal shipping insurance underwriting for Gulf transits, with war-risk premiums on tankers operating in the region remaining at multiples of pre-war levels. Industry data circulated last week showed total United States crude and petroleum product exports rising to a record 12.88 million barrels per day, as Asian and European buyers shifted procurement away from disrupted Gulf supply lines.

What does the stalled diplomacy mean for the central bank decisions arriving this week?

The diplomatic stall lands at the start of an exceptionally dense week for global monetary policy. The Bank of Japan delivers its rate decision early in the week, with policymakers expected to hold the benchmark policy rate at 0.75%, but with markets watching for any guidance on the timing of further normalisation steps. Bank of Japan Governor Kazuo Ueda will hold a press conference following the decision, and any reference to imported inflation pressure linked to elevated oil prices will be closely parsed by yen markets and broader Asian risk assets.

The Bank of Canada and the United States Federal Reserve issue back-to-back decisions on Wednesday. The Bank of Canada is expected to hold its policy rate at 2.25%, while the Federal Open Market Committee is expected to leave the federal funds target range unchanged at 3.75% to 4.00%, following the September 2025 cut that took the corridor to 4.00 to 4.25% and a further reduction earlier in 2026. United States Federal Reserve Chair Jerome Powell will hold the post-decision press conference, with the dot plot and summary of economic projections not scheduled for release at this meeting.

The Bank of England and the European Central Bank deliver decisions on Thursday in a session that has been described in market preview notes as a super Thursday for global rates. The Bank of England is expected to hold its bank rate at 3.75%, while the European Central Bank is expected to leave the deposit facility rate at 2.00%, with markets assigning a high probability to a hold. United States advance gross domestic product for the first quarter and the United States core personal consumption expenditures price index, the inflation gauge most closely tracked by the Federal Reserve, will land within the same window. The convergence of central bank communication, growth data, and inflation data against the backdrop of a renewed oil price shock raises the probability of elevated volatility across foreign exchange, sovereign rates, and equity index futures throughout the week.

How are mediators and regional powers managing the risk of escalation despite the failed Islamabad mission?

Iranian Foreign Minister Abbas Araghchi has continued an intensive shuttle through capitals viewed as sympathetic or neutral to Tehran’s position. Beyond Islamabad and Muscat, Iranian Foreign Minister Abbas Araghchi spoke by telephone with French Foreign Minister Jean-Noel Barrot, the Qatari Prime Minister, and counterparts in Saudi Arabia, according to Iranian state media outlet Tasnim News and the Qatari Foreign Ministry. The Iranian Ministry of Foreign Affairs confirmed that written messages had been transmitted to the United States via Pakistan, addressing what Iranian officials described as red lines on the nuclear file and on conditions for reopening the Strait of Hormuz.

The Sultanate of Oman, which mediated indirect United States-Iran talks earlier in 2025, retains a central role given its geographic position on the southern flank of the Strait of Hormuz. The Russian Federation, which Iranian Foreign Minister Abbas Araghchi reaches on Monday, brings additional weight as a permanent member of the United Nations Security Council and a long-standing strategic partner of the Islamic Republic of Iran. The Pakistani military and civilian leadership, working in tandem, have positioned Islamabad as the operational venue for any resumption of direct talks.

The fragility of the wider regional ceasefire architecture compounds the diplomatic challenge. Lebanese state media reported fresh Israeli strikes in southern Lebanon over the weekend, and the parallel ceasefire between Israel and the Lebanese militant group Hezbollah, recently extended by three weeks under United States brokerage, has come under increasing pressure. Hezbollah has not participated in the Washington-led diplomacy, leaving a separate vector of escalation that markets and policymakers cannot rule out.

What does sustained Brent at three-week highs imply for inflation, growth, and policy paths through the second quarter?

The combination of a stalled diplomatic process, a restricted Strait of Hormuz, and a packed central bank calendar increases the probability that energy-driven inflation pass-through becomes a central theme in second-quarter macroeconomic data. European purchasing managers index data released last week, referenced in pre-meeting analyst notes, indicated that the eurozone composite and services components had slipped into contractionary territory, while manufacturing remained in expansion, with cost pressures running at the highest level recorded since 2000 outside the COVID period. The German prints showed widening inflationary pressures, while the French data displayed more contained price passthrough.

For the European Central Bank, the data complicates the narrative of waiting for clearer evidence before acting. For the Federal Reserve, the inflationary pulse from energy collides with a labour market that Federal Reserve Chair Jerome Powell has said remains a primary focus, leaving the policy committee in a delicate position. For the Bank of Japan, imported energy inflation is a more direct transmission channel given Japan’s dependence on Gulf hydrocarbons, and any indication that the Bank of Japan is willing to accelerate normalisation could trigger renewed yen strength and a reassessment of carry positioning across global markets.

The Brazilian central bank, which is also scheduled to act this week, is expected to cut its policy rate by a further 25 basis points to 14.50% from 14.75%, having begun its easing cycle at the previous meeting. Brazilian policymakers explicitly cited the depth and duration of the Middle East conflict in their prior communication, signalling that the oil shock is now a formal input into rate-setting decisions even in jurisdictions far from the conflict zone. The configuration of stalled diplomacy, restricted Gulf shipping, and divergent central bank trajectories defines the macro landscape for the week ahead.
