LONDON, April 15 (Reuters) - The euro fell nearly one percent against the dollar and yen on Thursday as the cost of insuring against a Greek default rose, highlighting persistent concerns about how Greece will service its debt.
The dollar rose broadly, a day after stronger-than-expected corporate results and strong data pushed U.S. stocks up for a fifth straight day of gains on Wednesday.
The euro was on track for its biggest one-day fall in three weeks against the dollar as the Greek/German government bond yield spread also widened to near record levels hit before euro zone members agreed a standby aid package for Greece.
Ministers agreed to make available 30 billion euros in loans with a further 15 billion coming from the International Monetary Fund but markets remain concerned about uncertainty over how the financial assistance would be implemented.
"We see yields on Greek government bonds edging higher and certainly that issue is still very much in the market even though we have the package from the EU/IMF," said Svere Holvek, currency strategist at Danske Bank.
"There is still a concern whether Greece could finance debt in the longer term. The outlook for growth is not optimistic either."
By 1140 GMT, the euro <EUR=> was down nearly a full percent on the day to $1.3520, its lowest of the week. It traded more than a U.S. cent below the day's high of $1.3666.
The euro <EURJPY=R> fell more than 1 percent to 125.84 yen, with traders citing selling by U.S. investment banks.
Five-year Greek credit default swap prices rose to 455 basis points, exceeding a record closing high of 444 basis points hit a week ago.
Some in the market said selling by Middle Eastern names was helping push the euro lower against the dollar, and that a break through stop-loss orders around $1.3575 and below had exacerbated losses. The dollar <.DXY> rose 0.6 percent against a currency basket to 80.700, recovering from a four-week low of 80.031 hit on Wednesday. It was down slightly at 93.08 yen <JPY=>.

Key companies reporting first-quarter earnings later include Google <GOOG.O>. General Electric <GE.N> and Bank of America <BAC.N> are due on Friday.
Strong results could change the Federal Reserve's position, reiterated by Fed Chairman Ben Bernanke on Wednesday, that U.S. interest rates would stay low for an extended period.
The dollar recovered from earlier losses triggered after strong Chinese economic data ramped up speculation of a yuan revaluation, which is seen as negative for the dollar.
Data earlier on Thursday showed China's economic growth accelerated in the first quarter to 11.9 percent, the fastest annual pace in nearly three years, and consumer price inflation in March decelerated. [
]Analysts said improvement in the Chinese economy would bolster the argument for a strong yuan, and that the exchange rate may soon be freed up somewhat. Such a move is seen boosting Asian currencies to the detriment of the dollar.
"Our expectations are for a revaluation around mid-year, but now we see a risk of this happening earlier in the Q2," said Sven Schubert, currency analyst at Credit Suisse in Zurich.
