The Philippines is grappling with the fastest inflation rate among Southeast Asia’s major economies, as the country’s acute exposure to crude volatility from the United States-Iran conflict offsets the recent cooling in consumer price growth.

While aggregate inflation across the ASEAN-6 nations held steady at 3.7 percent in May, the Philippines recorded a headline print of 6.8 percent, according to a June 24 commentary by United Overseas Bank Ltd. (UOB) economists Jester Koh and Lau Zhuo Yi Justine. This figure remains well above the Bangko Sentral ng Pilipinas’s (BSP) four percent upper target ceiling. The regional grouping comprises the Philippines, Vietnam, Indonesia, Thailand, Malaysia, and Singapore.

Both the Philippines and Vietnam are characterized as seeing a “faster pickup in inflation pressures.” UOB noted that these two economies, where price pressures are “most acute,” face the most severe price movements relative to their peers.

Vietnam holds the second-highest inflation rate in the ASEAN-6 at 5.6 percent, followed by Indonesia at 3.1 percent. Rates were significantly lower elsewhere: Thailand at 2.8 percent, Malaysia at two percent (which has benefited from domestic subsidies), and Singapore at 1.8 percent.

Notably, the Philippines’ high inflation rate also stands out against broader Asian economies. India posted a lower inflation rate of 3.9 percent during the month, while China’s inflation clocked in at a modest 1.2 percent. Japan and Hong Kong stood at 1.5 percent and two percent, respectively.

With inflation pressures hitting Filipino households, the BSP kicked off its interest rate hiking cycle, raising key borrowing costs by 25 basis points (bps) in April, followed by another quarter-point hike in June. Between these scheduled policy meetings, off-cycle meetings remained on the table to address unprecedented supply shocks head-on.

This tightening mode, while necessary to curb price pressures, risks compromising the country’s gross domestic product (GDP) growth.

Domestic economic growth sharply moderated to a five-year low of 2.8 percent in the first quarter of 2026. This marked the third consecutive quarterly slowdown since the second half of 2025, a period marred by the eruption of flood-control corruption scandals.

Both domestic and offshore headwinds contributed to this anemic economic performance, prompting UOB to slash its full-year economic growth projection to 3.2 percent from five percent. If realized, this would be the weakest growth in six years, following the contraction seen in 2020.

President Marcos’s economic team also projects the economy to grow by a muted 3.5 percent to 4.5 percent, down significantly from its original five percent to six percent target.

A major contributor to this economic anxiety is the Philippines’ vulnerability to global energy shocks. Because the country relies on imports for over 90 percent of its oil, domestic fuel prices spike every time geopolitical tensions prompt threats to close the Strait of Hormuz.

Consequently, UOB raised its full-year headline inflation forecast to 7.5 percent from 5.5 percent. If this forecast holds true, 2026 inflation could mark the highest price growth since the 8.2 percent recorded in 2008 at the height of the global financial crisis.

Additionally, UOB sees a high probability of El Niño emerging from June through the third quarter, threatening to push food prices even higher by severely weighing on agricultural output.
