The key global economic risks to watch in the second half of 2026
Global Economic Crossroads: What Determines the Second Half of 2026
The key global economic risks to watch - A comprehensive analysis from Oxford Economics reveals that the latter portion of 2026 hinges upon a fragile sequence of interconnected events. At the center of this economic uncertainty stands the United States-Iran peace agreement, which serves as the primary variable determining whether global markets experience stability or turbulence. According to Ryan Sweet, the consultancy's chief global economist, the longevity of this diplomatic arrangement will ultimately decide whether economies benefit from energy-driven disinflation or face renewed oil market pressures.
The Oil Market as Economic Barometer
Oxford Economics projects that global economic expansion will accelerate significantly during the second half of the year. The consultancy anticipates annualized growth reaching 3.1 percent, a substantial improvement over the estimated 1.6 percent recorded in the first six months. This optimistic outlook rests heavily on reduced oil prices flowing through to consumer purchasing power. However, Sweet characterizes the probability of achieving a lasting agreement as merely "a coin flip."
Its durability will determine whether the global economy gets an energy-driven disinflation tailwind or absorbs a second oil shock.
Should the truce endure, Brent crude is expected to stabilize in the low $70s per barrel range. This price level would provide relief to emerging market economies and support technology sector valuations worldwide. Conversely, a collapse of the agreement would generate consequences extending far beyond energy markets alone.
Recent Military Developments and Market Response
Early Wednesday witnessed renewed hostilities when the United States military launched operations against Iran following Tehran's reported strikes on three vessels navigating the Strait of Hormuz. Iranian forces responded with attacks directed at both Bahrain and Kuwait. This regional escalation heightened concerns that the interim ceasefire could unravel completely.
Despite the intensity of the exchanges, the pattern mirrored previous incidents during the agreement's uncertain implementation period. Neither nation has yet indicated intentions to withdraw from diplomatic negotiations. Financial markets reacted swiftly, with oil prices surging more than 6 percent by Wednesday morning. The Brent crude benchmark climbed above $78 per barrel amid the uncertainty.
A peace deal breakdown won't just raise oil prices, it would also increase pressure on AI supply chains in Asia, force central banks to be hawkish, tighten financial conditions, and could shift the outcome of the US midterms and Israeli elections [...] the cascade runs fast.
Divergent Forecasts on Oil Trajectory
Not all analysts align with Oxford Economics' more optimistic oil price projections. Morgan Stanley's mid-year assessment, released in May, anticipates crude prices returning to approximately $90 per barrel by year's end. This represents a $20 divergence from Oxford Economics' estimate, reflecting fundamentally different expectations regarding the peace process outcome.
The World Bank maintains an even more cautious position, projecting Brent crude to average around $94 per barrel throughout 2026. Simultaneously, the institution warns that worldwide GDP expansion will decelerate to 2.5 percent during the same period.
Key Indicators for Agreement Durability
Sweet identifies commercial traffic through the Strait of Hormuz as a critical measurement tool for assessing the truce's stability. The diplomatic arrangement specifically committed to completely restoring navigation through this strategic chokepoint within thirty days, establishing mid-July as the initial definitive deadline.
Traffic through the Strait of Hormuz is a good bellwether. The deal committed to fully restoring traffic through the chokepoint within 30 days, making mid-July the first hard deadline.
According to Sweet, maintaining 75 percent or higher of pre-conflict shipping volumes by mid-July would strengthen confidence in the agreement's survival. A secondary indicator involves whether Iran formally activates the accord's Lebanon provision concerning Israeli military actions, and whether subsequent responses manifest through armed force or diplomatic statements.
Trade Policy and AI Sector Vulnerabilities
International commerce faces additional headwinds as US Section 122 tariffs approach their July 24 expiration date. Washington has already prepared alternative levies under Section 301 legislation. Oxford Economics projects that effective tariff rates will climb beginning in late July as American policymakers work to sustain monthly tariff collections between $25 billion and $30 billion.
European nations are simultaneously adopting more aggressive trade positions. The European Commission currently conducts over 50 trade-defence investigations targeting Chinese exports, compared to just 17 twelve months prior. A comprehensive economic security framework is scheduled for September announcement.
These commercial tensions intersect directly with the artificial intelligence expansion that has driven financial markets throughout 2026. Oxford Economics highlights that American AI enterprises rely extensively on semiconductors and hardware components manufactured in Northeast and Southeast Asia. These same regions face the greatest exposure to any additional disruptions in Strait of Hormuz commodity shipments.
The Bank for International Settlements has issued warnings regarding the AI sector's financial architecture. The central bank umbrella organization notes that artificial intelligence growth increasingly depends on opaque "circular financing" arrangements connecting semiconductor producers, cloud computing providers, and AI research facilities. Additionally, lightly regulated private credit markets have expanded dramatically, with lending to the AI industry quadrupling over the past five years. This dependence on non-traditional funding sources creates vulnerability, as Sweet observes that an AI sector contraction could trigger broader financial instability.
