Most European stock markets closed lower on Friday despite efforts one day earlier by the European Central Bank to boost economic growth via interest rate cuts. The euro hit a two-year low against the U.S. dollar after Thursday\'s interest-rate cut by the ECB brought its key lending rate to 0.75% and made the currency even less appealing. The euro closed Friday at $1.226. The spread between Italian 10-year bonds and the German benchmark, a key indicator of investor faith in Italy\'s ability to weather the debt crisis, rose 10 points to end the day at 467. Italian bond yields reached 5.99%. Spain\'s 10-year government-bond yields rose past 7%, an unsustainable level and one that could push the country to seek a bailout, similar to that of Greece or Portugal. (ANSAmed).
