PPP exchange rates #

This category group contains information states of purchasing power parity (PPP) exchange rates and related concepts. A PPP exchange rate here is the spot price of a local currency per USD in the spot foreign exchange market that would equalize local and foreign prices. Information states are derived from vintages of (annual) official estimates and subsequent estimations based on relative consumer price index changes.

PPP USD exchange rates #

Ticker : PPPFXRATE_NSA

Label : PPP exchange rate, local currency per USD

Definition : PPP exchange rate, local currency per USD, estimate.

Notes :

  • PPP exchange rates are local currency prices in USD that equate the value of price baskets across currency areas. They are sometimes used as reference for long-term equilibrium exchange rates, following the “law of one price”. Technically, they are ratios of prices in the local currency area to prices in the United States.

  • JPMaQS information states of PPP exchange rates combine annual “official” PPP releases and CPI-based estimates of monthly changes up to the latest month for which CPIs have been released for both the local economy and the United States.

  • There are two official sources of estimation of annual PPP exchange rates: the OECD, for its member states, and the World Bank, for non-OECD countries. The OECD follows the the “Eurostat-OECD” method based on rolling annual special price surveys. The World Bank’s method for non-OECD countries uses irregular price surveys intermittently every few years and estimates other years based on annual GDP deflators. As of October 2023, the last price survey year used for the non-OECD calculations was 2017 and the preceding survey year was 2011. For the exact calculation of annualised PPP conversion factors see Appendix 1 .

  • The methodological differences between OECD and non-OECD explain the more drastic revisions of data vintages for the non-OECD countries. For instance, from 2005, until the next base year, the PPP figures for non-OECD countries were calculated using the extrapolation methodology. Then, in April 2014, the annual observation periods from 2005 were recalculated using the rolling PPP Fisher-type index. In some cases this triggered huge revisions of the originally extrapolated series, because estimation errors that had accumulated over many years were revealed. For further information please see ICP 2011 results were released in April 2014 [worldbank.org] .

  • To estimate at a monthly frequency, we use CPI vintages for the involved currency areas. Then we use a “double price ratio” to estimate and interpolate PPP exchange rates from the latest base year, i.e. the latest year for which official PPP exchange rates have been published. This is the ratio of (1) the local CPI in month m divided by the average CPI of the base year and (2) the local CPI in month m divided by the average CPI of the base year . The calculations are rebased after each new release of annual PPP exchange rates. For details, see the bottom of Appendix 2 .

  • The PPPs under the International Comparison Programme, ICP, have a broad coverage of goods and services, as PPPs are designed to convert the nominal value aggregates in national accounts into real value aggregates. Therefore, the consumption basket used in headline CPI is reasonably well aligned to that of ICP.

  • The Euro series, EUR_PPPFXRATE, will comprise a weighted average of the PPP conversion factors for Italy, France, Germany, Netherlands and Spain. The weights involved in the arithmetic mean will be the nominal GDP. Further, the series will commence from 1999 onwards to reflect the establishment of the Euro. However, for the first three annual observation periods, up until 2003, the PPP calculations for the Euro constituents still used the national currencies in the price relatives. Thus, the PPP figures for the aforementioned years will be multiplied by the fixed nominal exchange to ensure the indicator starts when the currency union was formed.

  • PPP exchange rate series for Romania, Russia and Turkey are adjusted for currency re-denominations in the late 1990s and 2000s.

PPP overvaluation ratio #

Ticker : PPPFXOVERVALUE_NSA

Label : Ratio of market price of currency and PPP-based price (overvaluation ratio)

Definition : Ratio of current market price of currency, based on spot exchange rate, and the estimated PPP-based price.

Notes :

  • A ratio above one indicates local-currency overvaluation versus the USD, based on the PPP exchange rate estimate. A ratio below one indicates undervaluation. A ratio of 1.2, for example, suggests that the local currency is 20% overvalued versus the USD based on the law of one price for comparable baskets.

  • The calculation tracks daily movements in the spot exchange rate relative to the concurrently estimated PPP exchange rate.

PPP excess overvaluation ratios #

Ticker : PPPFXOVERVALUE_NSA_P1MvLTXL1 / _P1DvLTXL1

Label : Excess ratio of market price of currency and PPP: % latest month / % latest day versus expanding long-term median.

Definition : Excess ratio of market price of currency and PPP-based price: % latest month over expanding long-term median since vintage inception lagged by one month / % latest day over expanding long-term median since vintage inception lagged by one day.

Notes :

  • See notes on “PPP overvaluation ratio”.

  • Long-term trends are also calculated based on the latest available full vintage of estimated overvaluation ratios. Latest month means latest 21 days.

  • To differentiate long-term trends from conventional trends, the percentage change will be calculated over an expanding median, as opposed to a moving average of varying time horizons. The expanding median will be lagged by one period (day or month).

The JPMaQS indicators we consider are downloaded using the J.P. Morgan Dataquery API interface within the macrosynergy package. This is done by specifying ticker strings , formed by appending an indicator category code <category> to a currency area code <cross_section> . These constitute the main part of a full quantamental indicator ticker, taking the form DB(JPMAQS,<cross_section>_<category>,<info>) , where <info> denotes the time series of information for the given cross-section and category. The following types of information are available:

  • value giving the latest available values for the indicator

  • eop_lag referring to days elapsed since the end of the observation period

  • mop_lag referring to the number of days elapsed since the mean observation period

  • grade denoting a grade of the observation, giving a metric of real time information quality.

After instantiating the JPMaQSDownload class within the macrosynergy.download module, one can use the download(tickers,start_date,metrics) method to easily download the necessary data, where tickers is an array of ticker strings, start_date is the first collection date to be considered and metrics is an array comprising the times series information to be downloaded.

History #

PPP exchange rate series #

PPP exchange rates of developed or emerging countries countries with similar inflation rates to the U.S. have been fairly stationary. Emerging countries with higher inflation rates have naturally seen an upward drift in the USD price in local currency. Low inflation or deflation countries, such as Switzerland and Japan have experienced a downward drift.

The data also show the effect of the World Bank’s revision cycle, with a number of sharp upward and downward shifts in EM PPP exchange rates on the days of publication.

PPP overvaluation ratio #

Overvaluation ratios have been stationary in the long-term. This suggests that PPP exchange rates have exerted some long-term “gravity” on spot exchange rates: price differences may have remained but they did not drift apart on a sustained basis. Exceptions were Japan and Singapore, but even in these countries the residual drift was gentle.

Excess overvaluation ratios, as opposed to simple overvaluation ratios, are particularly important as predictors of emerging markets FX returns. Unlike simple overvaluation ratios they do not imply structural long or short positions across currencies.

Appendix 1: How official annual purchasing power parity exchange rates are calculated #

Conceptually, PPP exchange rates are ratios of prices for comparable goods and services in local and foreign currency areas. They are exchange rates for which comparable goods and services would cost the same in both places.

PPP exchange rates are based on a Fisher-type index whereby the aggregate PPP exchange rate level is a weighted average of elementary PPP exchange rate levels. Each elementary PPP exchange rate represents a basic heading, covering similar goods and services across areas. An example of a basic heading would be wine which is disaggregated into the three groups: red wine, white wine and sparkling wine. At the elementary level, basket indices do not use weights and a geometric mean is calculated. The prices used for the elementary PPP exchange rates are annual averages. Index number formulae beyond the elementary level are derived using systems of weights. Thus, to produce the aggreate PPP exchange rate, the procedure is broken into three steps: i) a matrix of Laspeyres-type PPP exchange rates; ii) a matrix of Paasche-type PPP exchange rates; iii) a geometric mean of the two, a matrix of Fisher-type PPP exchange rates.

For detailed methodological notes, please see here .

Appendix 2: How JPMaQS monthly purchasing power parity indices are calculated #

Higher-frequency PPP indices are estimated based on price index ratios, which is principally a standard procedure in the literature:

  • https://en.wikipedia.org/wiki/Purchasing_power_parity

  • https://ec.europa.eu/eurostat/web/products-manuals-and-guidelines/-/ks-ra-12-023

Here the estimate of monthly PPP exchange rates based on annual releases uses point-in-time estimates of CPI ratios. The last release of PPP will be multiplied by a ratio of CPIs between the local currency area and the U.S. with the average of the CPI ratio set to 1 for the last available official annual PPP survey. Thus, the calculation takes three steps:

First, for monthly estimation we use CPI “double ratios”: Those are the ratios of (1) local currency CPI at a given month to the average CPI for the last reported PPP year relative to (2) U.S. CPI for the same month to the average CPI for the last reported PPP year. Average here means the arithmetic mean of CPI over the 12 months of the last reported PPP year (T).

This choice of CPI base reflects that PPP exchange rates of the OECD and World Bank are based on annual averages of the surveyed prices.

The double CPI ratio applied for PPP exchange rate estimation for month m is first calculated as the ratio of change in the CPI index for the local currency to the 12-month base year mean. As a measure of change in the PPP exchange rate, we take the ratio of this local currency change in index to the USD change in the CPI index relative to the base year. Lastly, we multiply this double ratio with the latest official annual PPP exchange rate to obtain the month PPP exchange rate estimate.

The above calculation will be completed for each new monthly release up until the next annual release for PPP exchange rate at \((T + 1)\) . This applies to both forward estimation and (backward) interpolation for monthly PPP exchange rates.

Following \((T + 1)\) ’s release, the described sequence of calculations will be applied to the new base year to give a new vintage; the monthly PPP exchange rates will use \((T + 1)\) as the base year.
