The Philippines passes the classic reserves test best in Asia — at 18.3%
On the Guidotti–Greenspan benchmark the Philippines has the strongest reading of the nine Asian markets compared here. But reserves are only 22.8% of GDP and fell 5.4% in the first eight months of 2026, which is why one ratio is not an answer.
Can Philippine reserves cover the short-term external debt?
Several times over, and by the widest margin in this comparison. At the end of December 2025 short-term external debt was US$20,233 million against gross international reserves of US$110,833 million, so the debt was 18.3% of reserves (BSP; World Bank QEDS).
The Guidotti–Greenspan benchmark asks that reserves cover all external debt falling due within a year — a ratio of 100% or less.

Read as pass-or-fail, this table says the Philippines is the safest economy in the group and Singapore the most exposed. Nobody believes that. The ratio measures a different thing in each place, and understanding the difference is more useful than the ranking.
Each authority publishes reserves on its own definition and these are not interchangeable. The Philippines and Thailand report gross international reserves; Japan, Singapore, Malaysia and Indonesia report official reserve assets; Hong Kong reports official foreign currency reserve assets; Taiwan reports foreign exchange reserves, which exclude gold, SDRs and the IMF reserve position. No figure here has been converted from one definition into another. GDP for 2025 is an IMF World Economic Outlook estimate.
On the other measure the Philippines is near the bottom
Reserves relative to the size of the economy give a different ranking. At the end of December 2025 gross international reserves were 22.8% of 2025 GDP, seventh of the nine markets, ahead only of Indonesia.
| Market | Reserves, end-2025 (US$ m) | GDP 2025 (US$ bn) | Reserves ÷ GDP |
|---|---|---|---|
| Hong Kong | 427,934 | 427 | 100.1% |
| Singapore | 409,276 | 604 | 67.8% |
| Taiwan | 602,550 | 920 | 65.5% |
| Thailand | 281,872 | 577 | 48.9% |
| Japan | 1,369,775 | 4,435 | 30.9% |
| Malaysia | 125,532 | 472 | 26.6% |
| Philippines | 110,833 | 487 | 22.8% |
| Indonesia | 156,471 | 1,446 | 10.8% |
Reserves also fell in 2026. At the end of August they were US$104,813 million, down 5.4% from the end of 2025, a figure BSP flags as preliminary. Over the same period Japan fell 11.8% and Indonesia 6.4%, while Singapore rose 5.8% and Malaysia 5.2%.
The reading for someone here is that the two tables answer different questions. The debt ratio asks whether the next year’s obligations are covered; the GDP ratio asks how much buffer exists relative to the economy that has to be defended. The Philippines is first on one and seventh on the other, and both are true.
Why the same ratio means different things
In Singapore, Hong Kong and Japan the numerator is dominated by the cross-border liabilities of an international banking centre: non-resident deposits and interbank funding raised abroad, matched by external assets the ratio does not show. Their readings scale with the size of the financial sector.
In the Philippines the same line is closer to what the benchmark was built for — external borrowing that has to be refinanced or repaid. That is why the number is low and why it is meaningful when it moves.
The Philippines operates a floating exchange rate within an inflation-targeting framework, so reserves absorb swings in capital flows rather than defending a set level of the peso. Gross international reserves are also a gross concept: they do not net off the central bank's own short-term foreign liabilities, which is why BSP publishes a separate net figure. This paragraph interprets the framework; the figures in the tables are observations from the published statistics.
What to check when reading these numbers
Start with the definition. Four different reserve concepts appear in the tables above and they are labelled for that reason. Two figures are only comparable when they carry the same label.
Then check the maturity concept. The short-term external debt used here is measured by original maturity of one year or less, which is what the Quarterly External Debt Statistics publish. The Guidotti–Greenspan benchmark was framed around remaining maturity, which is a different and usually larger number. The two should not be swapped.
Finally check the reference date and its status. Reserves here are end-December 2025 so they line up with the debt figure for the same quarter; the August 2026 figure quoted in the text is later, preliminary, and is not mixed into the ratio tables.
Questions & answers
How large are Philippine gross international reserves?
US$110,833 million at the end of December 2025 and US$104,813 million at the end of August 2026, a fall of 5.4%. BSP flags the August 2026 figure as preliminary. The end-2025 figure equals 22.8% of 2025 GDP.
Does the Philippines pass the Guidotti–Greenspan benchmark?
Yes, by the widest margin in this comparison. The benchmark asks that reserves cover all external debt due within a year, meaning a ratio of 100% or less. Philippine short-term external debt was 18.3% of reserves at the end of 2025, against Thailand at 25.2%, Indonesia at 29.9% and Singapore at 372.7%.
If the debt test is the strongest in Asia, is the position strong overall?
Not on every measure. Reserves were 22.8% of 2025 GDP, seventh among the nine markets here, and they fell 5.4% in the first eight months of 2026. The debt ratio and the size ratio answer different questions, and a single ratio is not a verdict.
Are the reserve figures in this note comparable across markets?
Only with care. The Philippines and Thailand report gross international reserves, Japan, Singapore, Malaysia and Indonesia report official reserve assets, Hong Kong reports official foreign currency reserve assets, and Taiwan reports foreign exchange reserves excluding gold. The definitions are named in the tables and are not converted into one another.
