Gulf economies are expected to grow significantly in 2027 after suffering an economic slowdown in recent months caused by the Iran-US conflict.
The GCC (Gulf Cooperation Council) economies are expected to grow by 8.1% next year, with energy flows, tourism and investor sentiment to gradually normalise as war disruptions subside, the Institute of Chartered Accountants in England and Wales (ICAEW) and Oxford Economics said in a new report.
Regional economies incurred substantial economic damage as the conflict's shockwaves, whether through missile strikes on critical energy and oil architecture, disrupted shipping lanes, or upended trade and aviation networks, swept through markets, industries and countries.
Saudi Arabia’s national output for the first quarter slowed to 3% year on year and non-oil activities expanded at its slowest pace since the Covid-19 pandemic. The kingdom’s seasonally adjusted GDP contracted 1.2% quarter-on-quarter driven by a 6.8% fall in oil activities as the Strait of Hormuz disruption hit late in the quarter, the Middle East's economic update revealed.
Barring Oman, all GCC producers alongside Iran and Iraq, have suffered extensive energy production losses, with overall production having dipped to half of pre-war levels. Decoupling efforts, including Saudi Arabia's East-West Pipeline and the UAE's Habshan-Fujairah pipeline, have helped prevent an even larger plunge in output.

Meanwhile, economies such as Kuwait, Iran, Iraq and Qatar, bore the brunt of the conflict, for their inability to avoid the disruption to regional shipping, war-driven infrastructure damage and tourism losses.
“We forecast GCC oil sector output to contract by 14.5% this year, which will mark the steepest decline in several decades. We then expect a 23.5% rebound next year, driven largely by normalisation from a severely depressed base,” the report added.
Non-oil activity in Saudi Arabia and the UAE, however, appears on a rebound with May PMI surveys reporting the strongest output levels in three months, driven by improved domestic demand.
“Overall, we expect a 1.1% contraction in GCC non-energy sectors this year - compared to 4.2% growth pre-war - and a gradual recovery over the rest of the decade,” the study stated.
The Middle East is expected to contract 4.1% this year, surpassing the downturn witnessed during the first year of the Covid-19 pandemic, according to the study. Iran’s GDP is likely to shrink by 10.8% this year, while Iraq’s economy is estimated to contract further by around 22% in 2026, with a sharp 33% rebound in 2027 as oil exports normalise. Lebanon faces a 6.5% contraction in 2026 amid ongoing Israeli strikes, occupation in the south of the country and forced displacement of 20-25% of the population, the report added.
“By contrast, Syria continues to reintegrate into the global economy after more than a decade of civil war. We anticipate GDP growth to average 9.6% over 2026-2027, supported by renewed investment,” the study said.
Oil prices have risen around 10-12% since the conflict began on February 28, hitting a year-high peak of $115 in late March before easing to around $86 on June 12. Brent prices stood at $78.5 at 11.27pm GMT time on June 18.
“In our baseline forecast, we expect oil prices to remain above pre-war levels as exports gradually normalise, with Brent oil price averaging around $90 per barrel this year. In the medium term, we expect oil prices to be slightly lower than our pre-war baseline, as the UAE’s departure from OPEC+ allows for a gradual increase in its output towards the 5mn barrel per day production target once trade normalises,” the study adds.
