Overview
Markets reopened after the long holiday weekend to volatile headlines and rapid policy reactions. A two-week ceasefire, announced late on Tuesday and brokered in Pakistan, initially produced a significant market rally. The announcement knocked Brent and West Texas Intermediate (WTI) crude prices down from more than $110 a barrel to under $100, and allowed global equities and sovereign bonds to climb as investors welcomed the temporary respite.
U.S. equity indexes rallied sharply on Wednesday, Asian markets posted strong gains and Europe’s STOXX 600 recorded its best trading day in over four years. Government bonds rallied and the dollar eased versus other developed-market currencies on hopes that the conflict had been paused for a meaningful period.
Ceasefire strains and energy market repercussions
That initial optimism proved short lived. Cracks began to appear in the ceasefire when, according to reports, Israel carried out its largest strike against Hezbollah since the outbreak of hostilities. Washington and Tehran publicly disagreed over whether the attacks on the Lebanese militant group were meant to be covered by the ceasefire, adding ambiguity to the agreement’s scope.
Shortly after the ceasefire announcement, Iran struck Saudi Arabia’s East-West Pipeline - described in reports as Riyadh’s only crude export route since the conflict began - further underscoring how fragile the pause in fighting had become. Those developments pushed crude prices back toward the $100 a barrel mark on Thursday and stalled the global equity relief move.
At the centre of market concern is the status of the Strait of Hormuz, a choke point for the global energy system. U.S. political comment suggested reopening the strait was a condition of the truce, but the waterway remained effectively closed. Reports indicated that Tehran is seeking to impose transit payments for ships passing through the strait, a demand that, if implemented, would be expected to keep energy prices elevated for an extended period. The dispute prompted a public rebuke from the U.S. executive who wrote: "That is not the agreement we have!" on a social media platform.
Diplomatic efforts are due to continue, with additional talks planned in Islamabad despite Iran calling such sessions "unreasonable" in light of new strikes in Lebanon and further military threats from the U.S. Israel has also announced plans to open separate discussions with the Lebanese government focused on ending the war there and disarming Hezbollah.
Market moves after the ceasefire - a mixed picture
Even with the fragility of the truce, markets have shown tentative signs of improving risk appetite. U.S. stock indexes advanced on Thursday and Asian equities rose on Friday, positioning them for their best weekly performance in more than three years. Ahead of further data releases, U.S. equities were flat before the opening bell on Friday.
However, any sustained pickup in risk assets may be constrained by the continuing disruption to oil production and shipments across the Middle East. Oil prices remain markedly higher than before the conflict erupted: Brent and WTI are reported to be up about 34% and 48% respectively since the war began on February 28. That persistent premium over pre-conflict levels suggests that a ceasefire alone would not immediately erase the energy shock.
Physical supply constraints and regional output losses
Beyond questions over transit rights, actual production capacity in the region has been reduced. Government figures cited show Saudi Arabia’s oil output down by roughly 600,000 barrels per day. In parallel, throughput on the kingdom’s East-West Pipeline has been reduced by about 700,000 barrels per day. These cuts to output and export capacity mean that even if exporters could resume shipments from the Gulf, a swift return to pre-conflict flows appears unlikely.
That prospect is particularly concerning for Asian markets, where physical energy availability is expected to be under strain for months even under optimistic assumptions about the diplomatic outcome. As a consequence, the reprieve for oil markets may be only partial, with persistent tightness in supply sustaining higher prices and related volatility.
Implications for inflation and monetary policy
Higher global energy prices add a difficult wrinkle for central banks, especially the Federal Reserve. Elevated fuel costs risk pushing consumer prices higher and could complicate efforts to keep inflation expectations anchored. Recent macro releases provide early signals that inflation pressures may be re-emerging. U.S. services purchasing managers’ indexes showed rising input costs, which can be an early indicator of renewed price pressure along supply chains. In addition, personal consumption expenditures (PCE) inflation figures documented an expected uptick in U.S. price increases in February, before the war began.
At the global policy level, warnings have been issued that the combined effect of higher prices and slower growth is a real risk. One international finance official is reported as saying that "all roads" now point toward higher prices and slower growth, a cautionary note for authorities concerned about the spectre of stagflation.
Minutes from the Federal Reserve released midweek signalled that more Fed officials are leaning toward a near-term rate hike in response to the renewed inflation risk. Nevertheless, most participants are said to retain rate cuts later in the year as the baseline path, with scope for larger easing if the conflict begins to weigh on employment. Policymakers and investors will therefore be closely watching the next release of U.S. consumer price index data for March as they assess whether the recent energy shock will feed through to broader inflation readings.
Outlook and investor considerations
The ceasefire produced a momentary easing in market stress, but subsequent events underscored how quickly that calm can evaporate. With production capacity impaired, the Strait of Hormuz effectively closed pending resolution of transit disputes, and the potential for further strikes or escalations, the environment looks set to remain unsettled.
For investors, this means continued attention to energy price trends and to policy responses from central banks. The interplay between persistent energy-driven inflationary pressure and monetary policy choices will be a key determinant of equity and bond market direction over the coming weeks. At the same time, regional developments - including whether the ceasefire holds and whether pipeline and shipping routes are secured - will materially influence the pace at which energy market stress eases.
Practical note
Given these dynamics, market participants may want to monitor oil price developments, regional production and transit reports, and forthcoming U.S. inflation releases closely. Those data points are likely to shape expectations of central bank moves and, by extension, the broader outlook for risk assets.
