GROWTH in developing Asia and the Pacific is expected to slow this year as the conflict in the Middle East disrupts trade and energy markets, the Asian Development Bank said on Friday (April 10), with the extent of the slowdown dependent on how long the crisis persists.
Regional growth could ease to 4.7% in 2026 from 5.4% last year, while inflation could rise to 5.6% from 3.0% in 2025, if hostilities persist through the third quarter of this year, the ADB said in its Asian Development Outlook.
If the fighting drags on for a year, the region could lose about 1.3 percentage points of growth over 2026 and 2027, the ADB said.
Developing Asia and the Pacific consists of 43 economies ranging from China and India to Georgia and Samoa, but excluding Australia, Japan, New Zealand, Singapore, and South Korea.
The estimates contrast with the report's baseline assumptions, which were finalised on March 10 and were based on a shorter one-month conflict. Under that scenario, growth is expected to slow only modestly to 5.1% in 2026 and 2027, with inflation projected to rise to 3.6% this year, before easing to 3.4% in 2027.
What U.S. President Donald Trump had described as a brief, four‑week campaign following U.S. and Israeli strikes on Iran on February 28 instead dragged on, as the conflict intensified into a sixth week of fighting.
The escalation continued until Trump agreed on Wednesday (April 8) to a two‑week ceasefire with Tehran, just hours before a self‑imposed deadline for Iran to reopen the Strait of Hormuz or face sweeping attacks on its civilian infrastructure.
A temporary halt in fighting and the reopening of Hormuz, the narrow waterway that typically handles about one-fifth of global oil trade, would allow Middle Eastern exporters to ship significant volumes of oil that have been trapped inside the Gulf since hostilities began.
"The ceasefire seems fairly fragile, and prediction markets are not putting a high probability that it is going to last," Park said, making it difficult to forecast whether it would materially improve the growth outlook.
