MANILA -- The Philippines' annual inflation rate shot up to its highest in more than 5 years in June, opening the door for a third rate hike this year as the central bank vowed to get the pace of price increases back inside its target as soon as it can.

Inflation quickened to 5.2 percent in June from May's 4.6 percent, exceeding the central bank's 4.3-5.1 percent estimate amid costlier food, alcoholic beverages and tobacco as higher taxes took effect this year.

"The higher-than-expected June inflation outcome is a setback," Bangko Sentral ng Pilipinas Governor Nestor Espenilla told reporters in a text message.

The central bank "reaffirms its strong commitment to ensure that inflation returns to within the 2-4 percent target range as soon as possible," he said.

"We will review and update our situational assessment and forecast inflation path."

The BSP raised interest rates last month for the second time in 6 weeks mainly to tame inflation, becoming the region's second central bank to deliver 2 hikes in a short time, along with Indonesia.

The central bank next meets to review policy on Aug. 9. Asked if policymakers would wait for that meeting to take action or act immediately, Espenilla declined to respond, saying "enough said for now".

Economists at Nomura expect a third 25 basis point hike on Aug. 9, and did not rule out further increases later this year.

"We believe inflation expectations are also likely to rise further, as evident in rising demand for wage increases," they said in a note.

The June inflation reading also surpassed the 4.8 percent forecast in a Reuters poll of economists, and brought the average inflation rate to 4.3 percent in the first half of 2018.

It also marked the fourth straight month that the pace of price increase was faster than the central bank's 2 to 4 percent goal for this year and next.

"Honestly even if BSP hiked (by) 100 bps 2 years ago, inflation would still have exceeded the unrealistically low and narrow 2 percent to 4 percent target," Bank of the Philippine Islands economist Jun Neri tweeted.

While the rise in consumer prices is largely supply-driven, the central bank has said a tighter monetary policy is needed to keep inflation expectations from spiking.

Higher interest rates should also provide support for the peso, which has lost 6.5 percent against the dollar this year, making it one of Asia's worst performing currencies.

Following the inflation data, the peso dropped to as low as 53.44 versus the dollar, near a 12-year trough. Manila's key stock index fell 1.4 percent.
