Data on the liquid asset ratio (“total approved liquid assets” over "total deposits and other prescribed liabilities") and minimum liquid asset requirement or MLAR are available from BPNG (2007) from 1976 to 2005 and from BPNG Quarterly Economic Bulletin (QEB), Table 3.13 from 2002 onwards. We use QEB data from 2002 onwards. (There is a discrepancy in 2002). From June 1999, the liquid asset ratio excludes cash reserve requirement deposits held at BPNG, and in October 2010 the MLAR was reduced to zero (see the notes to QEB Table 3.13).
