The WSJ Dollar Index finished the week at 95.03, down 1.63% over the period, according to the Wall Street Journal’s market-data coverage.

The WSJ Dollar Index tracks the U.S. dollar against a basket of foreign currencies and is designed to reflect a broader, trade- and flow-sensitive view of dollar strength than single-pair moves (like USD/JPY) alone.

What moved the dollar this week

Currency markets often swing on a mix of interest-rate expectations, risk sentiment, and relative economic outlooks. This week’s decline comes as traders weighed shifting views on rates and a series of cross-currents in global markets.

Late in the week, the dollar also weakened sharply against the yen after market signals suggested heightened official attention to currency moves—one factor that can amplify short-term volatility across the FX complex.

Quick snapshot

Why it matters

A weaker dollar can support U.S. exporters by making American goods more price-competitive abroad, while potentially raising the cost of imports for U.S. buyers. It can also influence commodity prices and the earnings outlook for multinational companies when overseas revenues are translated back into dollars.

Investors will be watching whether the move extends into next week—or whether it was primarily a reaction to short-term positioning and late-week catalysts. For the latest level and intraday changes, WSJ’s market-data pages track the index in real time.
