Currency and Exchange Rates
Which currency anchors assessments, and which are tracked?
The US dollar (USD) is the anchor currency: every assessment is expressed in USD. A single set of reference USD-to-currency exchange rates is applied consistently across all documents, data, and reports. 25 currencies are tracked against the USD, listed below with their currency codes. Each also carries a shortened display name, used wherever the full name will not fit — chart axes, legends, and narrow table headers. The current reference rates for every tracked currency are tabulated later on this page.
At publication, monetary figures are converted from this US dollar basis to the currency conventions commonly used in each country, so readers see values in familiar local terms.
Over what periods are reference exchange rates published?
Reference rates are published across three history bands, each pairing a reporting frequency with a look-back span so short-term comparison and longer-term trend analysis are both supported directly from the same dataset.
The Recent band's monthly frequency mirrors the monthly cadence on which every assessment is produced, so exchange-rate history stays aligned to the same production cycle as the prices and costs it converts. A preview of the latest rates for a few major currencies appears directly below; the full history for each band opens in its own panel underneath.
Full monthly, quarterly, and annual history for every tracked currency is available in the panels below.
These rates are refreshed with each monthly release, so a figure read here may differ from one saved earlier. Assessments always use the rate for their own reporting period, not the latest rate.
