South African consumers are continuing to keep their wallets tightly shut, according to data released on Monday. The South African Reserve Bank (SARB) said on its website that private sector credit demand dropped by 0.42 percent annually for the month of October. This followed a gain of 1.49 percent in September. For the same period, growth in the broadly defined M3 measure of money supply eased to 2.67 percent compared with four percent previously, the SARB added.
