  2. Motivation • Credit growth is a key driver for economy growth. • Low credit growth may hamper the economy growth, but excessive growth may fuel greater risks for macro and financial stability. • Effectiveness of monetary and macro-prudential polices to manage credit growth.

  3. Objective & Research questions What factors drive credit growth in Indonesia?  Liquidity?  Capital?  Credit risk?  Monetary interest rate policy (bank lending channel)?  Macro-prudential policy?  Interaction of banking characteristics with macro-prudential policy?  Interaction of monetary and macro-prudential policy?

  4. Literature review  Credit growth & monetary policy (bank lending channel)  Bernanke&Blinder (1992), Kashyap&Stein (1994), Morris&Sellon (1995), Gambacorta & Marques-Ibanez (2011).  Credit growth & macro-prudential policy  cross countries evidence: Claessens, et al (2011), Lim, et al (2011), Zhang&Zoli (2014), Cerutti, et al (2017),  case study of a country: Igan&Kang (2011), Wong, et al (2011), Jimenez, et al (2012), Aiyer, et al (2014).  Credit growth & banking characteristics (liquidity, credit risk, sources of financing, capital)  Bernanke & Lown (1991), Peek & Rosengreen (1995), Kashyap, et al (2002), Cornett, et al (2010), Gambacorta & Marques-Ibanez (2011), Kapan & Minoiu (2013), Klein (2013), Accornero, et al (2017).

  6. Variables (1)  MPI1: dummy variables of phase 1 macro-prudential policy (MP) Code 1 for loosening period Q1 2011-Q2 2012 , code -1 for tightening period Q3 2012-Q2 2015, and 0 otherwise.  MPI 2: dummy variables of phase II macro-prudential policy (MP) Code 1 for loosening period Q3 2015 - Q4 2016 and 0 otherwise

  7. Variables (2) Independent Variables’ description Expected variables sign LA/D The ratio of liquid assets (cash, + placement at the central bank, and high-grade securities) to deposit (%). NPL The ratio of the non-performing - loans to total loan (%). Cap_buffer Deviation of realized Capital +/- Adequacy Ratio (CAR) to minimum capital requirement ratio (%). Asset_shr The ratio of a bank asset to total +/- industry asset (%). It is adjusted to total industry asset in each period to account for possible time trend. Δlog(GDP) The quarterly change of log of gross + domestic product. Δ CB The quarterly change of monetary - interest rate policy BIrate. Δlog(CPI) The quarterly change of log of +/- Consumer Price Index

  8. Methodology  Dynamic panel model: Two-step Arellano-Bover/Blundell-Bond Generalized Method of Moments (GMM).  A consistent estimator, subject to: 𝜄 of ∆𝑚𝑝𝑕 𝑑𝑠𝑓𝑒𝑗𝑢 𝑗𝑢−1 of GMM lies between those of FELS (downward bias) and OLS (upward bias) (Bond (2002), Roodman (2006)).  Otherwise, utilize FELS with Nickel bias 1 𝑈−1  For large 𝑈 , dynamic panel bias is insignificant,  Number of instruments tend to explode with 𝑈 (Roodman, 2006).  Endogeneity : utilizing lagged of explanatory variables

  13. Indonesia case: A rise of risk-averse behaviour due to higher credit risk & liquidity pressure in the midst of economic slowdown leads to substantial lower credit growth despite the loosening policies.

  14. Conclusion  Post the GFC 2008/09, the role of monetary interest rate policy on the bank lending diminishes and affect credit growth indirectly through its stronger impact on credit risk.  The effectiveness of loosening macro-prudential policies to improve credit growth is subject to bank’s risk condition.  The ineffectiveness of both loosening monetary and macro-prudential policies to improve credit growth since 2015 is due to intensifying of banking risk-averse behavior.  Banks choose to have higher liquidity and stronger capital buffer to anticipate higher credit risk in the midst of economic slowdown, leading to substantial lower credit growth.  Policy challenges in Indonesia are to encourage banks to improve their risks management and address a sensible balance of the trade-off between banks’ risks and their role in intermediating funds.
