The euro plunged to 15-week low against the green currency and 11-year low versus the Japanese yen after the rise in 10-year bond yield at a bond auction today.

France sold 7.96 billion euros of long-term debt, namely 2012, 2023, 2035 and 2041 bills. Yet, the main focus was on the yield on the benchmark 10-year bonds which saw a rise in the yield to 3.29% compared with 3.18% in the previous auction. The rises in the yield add to concerns amid speculations rating agencies will cut the country's top credit rating.

Worries increase as the euro area's second largest economy is under threat of downgrade to its top credit rating by rating agencies.

Concerning the EUR/JPY pair, it remained near 11-year low the daily charts to trade around 98.62 after recording a high of 99.33 and a low of 98.54.

The trading range for the day is expected among the key support at 97.40 and the key resistance at 101.80.

For the dollar index, which tracks the dollar movements versus a basket of major currencies, it rose sharply, as the concerns enhanced demand on the dollar as a refuge, to touch a high of 80.60 compared with the day's starting level of 80.10.

Later in the day, the U.S. economy will release ADP employment change, initial jobless claims for the week ending Nov. 26 and ISM non-manufacturing for December.

Moving to the GBP/USD pair, it showed a drop despite the improvement in services; British services sector showed widening expansion in December as the PMI reading rose to 54.0 from the prior 52.1, exceeding forecasts of 51.5.

The pair is currently hovering around 1.5545 while recording a high of 1.5628 and a low of 1.5535.

The trading range for today is among key support at 1.5360 and key resistance at 1.5820.
