The euro extended its biggest quarterly slide versus the dollar since its inception as Greece struggled to avert a default.

The 19-nation currency’s share of global reserve holdings fell to the least in 12 years amid the European Central Bank’s unprecedented monetary stimulus. That contrasts with the U.S. Federal Reserve, which is on track to raise interest rates this year for the first time since 2006.

The euro fell 0.8 percent to $1.0747 as of 3:50 p.m. in New York, after sliding 0.5 percent on Monday and losing 11 percent the past three months, the biggest quarterly drop since the shared currency began trading on Jan. 1, 1999. It declined 0.9 percent to 128.91 yen, pushing its drop since Dec. 31 to 11 percent, its biggest quarterly loss since September 2011.

The Bloomberg Dollar Spot Index, which measures the greenback against 10 major peers, added 0.1 percent to 1,201.01. That extended a ninth successive month of gains, the longest winning streak in data going back to 2004.
