WOCU Value Calculation
The principles behind the WOCU have been vetted, analysed and approved by a wide group of Economists and Market Participants. The apolitical WOCU basket of constituent currencies comprises those of the current top 20 countries by Gross Domestic Product (GDP), as determined by the International Monetary Fund (IMF). Each country’s individual currency (the Euro is duplicated for Germany, France, Italy, Spain & Netherlands) is elegantly weighted based upon the relative importance of its GDP.
These relative weightings are adjusted biannually, based on published IMF World Economic Outlook (WEO) figures of changing GDP values. The importance of a WOCU member country changes with its economic growth or contraction: by its weighting being adjusted or its currency being promoted into, or demoted out of, the WOCU basket.
Re-weightings occur on the third Thursday of May and November each year at 16:00 UTC (Universal Time, Co-Ordinated) on a logically elegant basis, by WOCU Limited, the owner and distributor of the WOCU. Notwithstanding the logical calculation and publicly available figures it is based upon, reweighting oversight is provided by the independent WDX Institute .
