The US Dollar Index (USDX) is an index (or measure) of the value of the United States dollar relative to a basket of foreign currencies. These currencies are the Euro (constituting 57.6% of the weighting), Japanese Yen (13.6%), British Pound (11.9%), Canadian Dollar (9.1%), Swedish Krona (4.2%) and Swiss Franc (3.6%). The index started in 1973 -with the absolution of Bretton Woods- with a base of 100.000, and values since then are relative to this base. For example, if the current reading says 99.800, this means that the dollar has fallen 0.2% since the start of the index (99.800 - 100.000DXY trades with negative bias for the second straight day, though the downside seems limited. The Fed’s hawkish shift remains supportive of elevated US bond yields and favors the USD bulls. Geopolitical risks and trade war fears might contribute to limiting losses for the safe-haven buck.
