The American economy performed better than anticipated, according to third quarter numbers released this morning. The annual growth rate hit 2.8 percent, not the 2 percent or less that economists had expected. Across the pond, the European Central Bank cut interest rates to a record low 0.25 percent, triggering a market rally and a euro fall. Recent data show the European economy still struggling, but euro-watchers hadn’t expected a move until at least December. There is some doubt, though, that worried banks will pass the lower rates to customers.
