SAN FRANCISCO (MarketWatch) -- The euro briefly lost its grip on $1.28 Thursday, sinking to its lowest since September 2010, according to FactSet, as signs of continued stresses on Europe's banks put the shared currency and European stocks under pressure. The euro EURUSD -1.06% recently traded at $1.2807, down from $1.2939 late Wednesday. It slid as low as $1.2783, losing more ground against the dollar after two reports showing improvement in the U.S. labor market. Spain said its countries' banks will need to raise 50 billion euros ($65 billion) to deal with bad property assets. Additionally, shares of Italy's UniCredit SPA fell steeply for a second day after pricing a share sale at a 43% discount.
