LONDON/FRANKFURT, Jan 27 (Reuters) - Rising borrowing costs are giving a long-awaited lift to Europe's beleaguered banks, but they come with a sting in the tail. Last year central banks ended a decade of rock-bottom interest rates as the U.S. Federal Reserve and then the European Central Bank moved towards tightening. But while rising rates are good news for bank profits, they herald a slowdown in an economy hit by war and runaway prices that squeeze borrowers and could prick pricing bubbles, most notably in property. "On the one hand, interest rates are going up, which is good and helps banks," said Jerome Legras of Axiom Alternative Investments. Germany's financial regulator BaFin recently warned that a rapid rise in interest rates could weigh on some banks, and that loans may sour.
