Trump refuses to confirm whether the U.S.-Iran ceasefire is still in effect
On May 4 (local time), U.S. President Donald Trump declined to clearly state whether the ceasefire agreement between the United States and Iran remains in force during an interview. Earlier that day, he warned that any Iranian attempt to attack U.S. vessels in the Strait of Hormuz or the Persian Gulf would result in them being “completely destroyed.” However, he later added that, from a military standpoint, the conflict with Iran is “basically over.”
Recent conflict has not significantly slowed Iran’s nuclear program
U.S. intelligence agencies stated that recent hostilities have not meaningfully delayed Iran’s nuclear program. U.S. officials continue to assess that if Iran decides to develop nuclear weapons, it would still take approximately 9 to 12 months—largely unchanged from last year’s estimate. Iran’s stockpile of highly enriched uranium remains largely intact, and its whereabouts are unclear. Experts say this stockpile is a key factor in assessing Iran’s nuclear timeline.
Iranian officials say no nuclear negotiations are currently underway
On May 4, Rezaei, spokesperson for Iran’s parliamentary National Security Committee, stated that during a meeting with Foreign Minister Araghchi, the latter confirmed that Iran is not currently engaged in any nuclear negotiations and is fully prepared for all scenarios. Rezaei added that Iran is developing a new control mechanism for the Strait of Hormuz and will bar hostile vessels from passing through. He also stressed the need to support the “axis of resistance,” including Lebanon, and to closely coordinate diplomatic and operational efforts.
U.S. crude oil prices surge again
During early Tuesday trading in Asia, U.S. crude oil hovered around $104.90 per barrel after rising more than 2% on Monday as U.S.-Iran tensions escalated again. Iran significantly intensified military operations on Monday, launching drone attacks that set fire to oil facilities in the UAE and targeting multiple vessels in the Strait of Hormuz.
The UAE confirmed its air defense systems were responding to missile and drone threats, while firefighters battled blazes at facilities linked to the Abu Dhabi National Oil Company (ADNOC). This marks the most severe escalation since the early-April ceasefire. Iran’s Revolutionary Guard Navy even released a map claiming its control zone has expanded to include the UAE’s Fujairah and Khor Fakkan ports. Iran stated that the Strait of Hormuz is now fully under its control and that hostile vessels will be denied passage.
RBA expected to deliver a third consecutive rate hike amid inflation and labor market pressures
The Reserve Bank of Australia is expected to raise its cash rate by 25 basis points on Tuesday, marking its third consecutive hike in 2026, driven by persistent inflation. Of 33 economists surveyed, 30 expect a rate increase, citing stubborn inflation and a tight labor market as key obstacles to disinflation.
Since the outbreak of the U.S.-Iran conflict, elevated global oil prices have further intensified inflationary pressures in Australia. Meanwhile, the domestic labor market has shown resilience.
RBA Governor Michele Bullock and other board members have maintained a hawkish stance in recent remarks. The post-decision press conference is unlikely to deliver major surprises, but strong language is expected to reinforce the central bank’s commitment to anchoring inflation expectations.
Trump’s “Freedom Plan” meets Iranian military retaliation in the Strait of Hormuz
On Monday, President Trump launched a new initiative called the “Freedom Plan,” aiming to reopen the Strait of Hormuz using naval forces. The move triggered a strong Iranian response, marking the most significant escalation since the ceasefire four weeks ago. The U.S. military claimed it destroyed six Iranian boats, a claim Iran denied.
Conflicting reports emerged: the U.S. stated that two American commercial vessels successfully transited the strait, while Iran’s Revolutionary Guard said no commercial ships had passed in recent hours and claimed it fired on a U.S. warship, forcing it to retreat.
Multiple commercial vessels were reportedly attacked: a South Korean ship caught fire after an explosion in the strait; ADNOC said one of its empty tankers was struck by an Iranian drone; and a major oil port experienced a fire. The UAE described the attacks as a serious escalation and reserved the right to respond.
There are currently no signs of a large-scale resumption of commercial shipping, with major shipping companies indicating they may wait until the conflict formally ends. U.S. Central Command said some missile destroyers have entered the Gulf to provide support but did not disclose further details.
Iranian authorities released a map showing an expanded area of control extending to the UAE coastline. Trump has struggled to resolve Iran’s blockade of the strait and its disruption to global energy supplies—prior to the conflict, the waterway handled roughly one-fifth of global oil and LNG shipments.
