An Outsized Rate Hike That Did Not Stop the Slide: Policy Limits for the Philippine Peso

Key takeaways

1. The Bangko Sentral ng Pilipinas raised its policy rate by 50 basis points to 5.50% on Thursday 22 October, a move only one of 25 economists in a Bloomberg survey expected.

2. The peso still closed at a record low of 63.52 per dollar, as oil above $110 and steady demand for dollars outweighed the higher rate (Philstar citing the Bankers Association of the Philippines).

3. A rate hike supports a currency only when the main pressure is about rates; when the pressure comes from the trade balance, expect the effect to be smaller.

The development

The Bangko Sentral ng Pilipinas (BSP) raised its target reverse repurchase rate by 50 basis points to 5.50% on Thursday 22 October. Only one of 25 economists in a Bloomberg survey expected a move of that size; the rest expected 25 basis points (Bloomberg via The Straits Times). Inflation reached 7.2% in September, against a 3% target. The BSP kept its 2026 forecast at 6.1% and raised its 2027 forecast to 6.0% from 5.4%, and it has raised rates by 125 basis points since the Iran war began (Bloomberg via The Straits Times).

The peso did not recover. It closed at a record low of 63.52 per dollar, 15.9 centavos weaker than Wednesday's close of 63.361, after touching 63.545 intraday (Philstar citing the Bankers Association of the Philippines). Trading volume rose to $1.72 billion from $1.34 billion.

Market transmission

A higher policy rate usually supports a currency by raising the return on local assets. The Philippines relies heavily on imported fuel and food (Bloomberg), so a higher oil price increases the demand for dollars to pay for imports. Brent crude settled at $113.17 on Thursday after Houthi attacks on Saudi Arabia (CNBC). MUFG Research noted that oil-sensitive currencies such as the Indonesian rupiah, the peso and the Thai baht stayed under pressure even as US Treasury yields fell. When the trade channel is this strong, a rate hike cannot fully offset it.

Governor Eli Remolona expressed concern about the peso's effect on imported inflation, but said the BSP would not use up reserves to defend a specific level (Bloomberg via The Straits Times). In effect, the central bank is aiming to slow the pace of the move rather than to fix a level.

What to monitor next

• Brent crude and shipping news from the Red Sea, the main external driver.

• Whether the peso approaches 64 per dollar, which one local economist called a realistic near-term risk (Philstar).

• BSP comments on market intervention and any change in the pace of reserve use.

• The next BSP meeting in December, which Pantheon Macroeconomics does not view as a certain hike.

Reusable lesson

Before relying on a rate decision to support a currency, identify the source of pressure. If it comes from interest-rate differentials, a hike can work. If it comes from the trade balance, such as an oil import bill, the hike treats only part of the problem. Size positions in such currencies for the larger, external risk, not for the central bank's response.

Invalidation and risk

A sharp fall in oil, or a ceasefire in the region, would ease the pressure quickly. A broadly weaker dollar would also help. In the other direction, onshore peso trading takes place during Manila hours, and quoted prices outside those hours can be thin and wide.
