The peso shock: exchange rate versus local prices
BSP exchange-rate tables show the external price of the peso. Philippine CPI shows how the prices paid by households changed. Imported goods can transmit an exchange-rate shock, but not every consumer purchase is imported and the percentages are not interchangeable.
If the historical question is ‘what could ₱1,000 buy in the Philippines?’, start with CPI. If it is ‘how many US dollars did ₱1,000 buy?’, use the dated BSP exchange rate instead.
| Measure | Answers | Does not answer |
|---|---|---|
| Philippine CPI | Broad domestic consumer-price change | Historical USD/PHP |
| USD/PHP rate | External currency conversion | Whole household cost of living |
| Wage figures | Pay for a defined worker group | National price level |
What Philippine CPI says about household prices
An annual CPI comparison follows the average price path across consumer categories. It smooths the sharp differences between months and between food, fuel, housing and services.
The 1997 amount should therefore be described as a broad national estimate. A crisis-month receipt or a particular imported product needs monthly and item-level evidence.
How to read a 1997-to-today estimate
Start with what a similar general basket would cost today. Then check local prices, wages or the old exchange rate if that is what your question is really about.
Do not treat today’s peso result as an investment return, a legal damages figure or the resale value of a 1997 banknote.
