LONDON—The euro sank to a two-decade low versus the dollar on Tuesday as another surge in natural gas prices reignited worries about the health of the eurozone economy and data showed eurozone business growth slowed sharply in June.
The euro tumbled 0.9 percent against the dollar to $1.0325, its weakest since December 2002. Versus the Swiss franc, it dropped 0.7 percent to 0.9941 francs, its lowest since 2015.
