CHASE CUTS PRIME RATE TO 18 1 2%
The Chase Manhattan Bank cut its prime lending rate yesterday for the second time this week, lowering it one-half percentage point, to 18 1/2 percent, but no other major banks followed its lead. Last Monday, when Chase reduced its rate to 19 percent, most of the nation's banks followed. ''Banks are uncertain about the big fluctuations in interest rates and also over near-term Federal Reserve Board monetary policy,'' said David M. Jones, an economist with Aubrey G. Lanston & Company.
