SPAIN QUALIFIES RESERVE REQUIREMENTS STATEMENT A Bank of Spain spokesman qualified a bank statement announcing an extension of reserve requirements to convertible peseta funds held by banks, saying the move applied only to future rises above current balances. "The 19 pct reserve requirement will only be applied to further increases in bank's convertible peseta funds," the spokesman said. Convertible peseta funds previously were exempt from reserve requirements. The spokesman said the measure was intended to curb an influx of short-term foreign speculative capital which threatened the government's money supply growth target.
