A rate hike is not a peso defense strategy

PHILIPPINES - Report 03 Nov 2026 by Diwa Guinigundo

The BSP's recent 50-basis-point policy rate increase should be understood primarily as a response to mounting inflationary pressures, not as an attempt to defend a particular peso-dollar exchange rate. Under its inflation-targeting framework, the central bank's principal responsibility is price stability. While peso depreciation contributes to imported inflation and can affect inflation expectations, exchange-rate movements are influenced by several forces, including global dollar strength, interest-rate differentials, capital flows, market sentiment and investor confidence. The peso's partial recovery in recent days, following the President's assurance that the government has the tools to address excessive weakness, further illustrates that currencies can respond to policy signals and changing market expectations, not simply to domestic interest-rate adjustments. It is therefore misleading to judge the effectiveness of monetary policy by the peso's immediate reaction to a rate hike.

More importantly, monetary policy cannot address the structural weaknesses underlying the peso's vulnerability on its own. Persistent trade deficits, dependence on imported energy and production inputs, limited export diversification and governance concerns require complementary fiscal, structural and institutional reforms. The country must strengthen its export capacity, improve productivity and competitiveness, attract productive investments, make public spending more efficient and restore investor confidence through transparency and accountability. The challenge is not merely to manage the demand for dollars, but to expand the country's capacity to earn them. Ultimately, a stronger and more resilient peso must be supported by stronger economic fundamentals, sustainable foreign-exchange earnings and credible institutions—not by higher interest rates or repeated foreign-exchange intervention alone.
