The euro slid for a second straight session against the US dollar on Wednesday as a Chinese interest rate hike raised global growth concerns in a market already rattled by a downgrade of Portugal's debt to junk. In midday New York trading, the euro was down 0.7 percent at $1.4328, the lowest since June 28. Risk aversion also pushed the euro lower against the safe-haven Swiss franc. It shed 0.9 percent to trade at 1.2028 francs.
The dollar sustained losses against the yen after a report showed sluggish growth in the US services sector in June. The dollar last traded down 0.2 percent at 80.82 yen.
