US Dollar Index (DXY) news & analysis

The US Dollar Index (DXY) measures the value of the US dollar against a basket of major world currencies.

Why is the US Dollar Index up or down today?

The US Dollar Index is hovering above 99.50, supported by safe-haven demand from Middle East tensions, while a pause in the post-NFP selloff adds to the consolidation. Softer labour data has shifted the Fed outlook, prompting some experts to suggest the dollar's rally may have run its course, leaving the index at a crossroads ahead of CPI data.
