The study evaluated how well Indonesia's monetary policy affects interest rates on deposits and loans in commercial banks. Using data from 2005 to 2016, the researchers found that changes in the money market interest rate did not fully impact deposit and loan rates. The adjustment of interest rates in response to market changes was slower for consumer loans and deposits with a 24-month term. This suggests that interest rates on consumer loans and deposits in Indonesia are not very responsive to changes in interbank rates.
