InterContinental Hotels Group's room revenue growth slowed in the second quarter as a sharp decline in the Middle East offset continued gains in the United States and China. The Holiday Inn owner reported global revenue per available room (RevPAR) growth of 3.5% in the three months to June, down from 4.4% in the first quarter. However, the Iran war, now in its sixth month, has weighed on hotels and travel companies in the Middle East. Both companies also reported weaker revenue from the Middle East. The Middle East, part of IHG's second-largest EMEAA region and accounting for about 5% of global revenue, recorded a 19% drop in RevPAR in the second quarter.
