Abstract

This study was conducted to assess the vulnerability of Islamic banking credit portfolios under macroeconomic shocks and their impact on NPFs, using the linear regression analysis. From the three proposed models, namely OLS, ARIMAX and Error Correction Model (ECM), the ECM model was selected as the best. By using the Montecarlo simulation, an estimate was made of the possible future value of the NPF in Islamic banking. The study established that exchange rates, economic disparities, inflation, economic growth and interest rates showed positive and significant effects on bank credit risk whereas inflation produced negative effects. The non-performing finance (NPF) was also estimated using the Montecarlo simulation using one million trials. The results were subsequently used to conduct a stress test for the projected NPF. With 99% confidence, the maximum potential value of bad credit was 21%. The maximum NPF bad credit was attained under confidence level of 95%.

使用蒙特卡罗模拟的信用风险历史压力测试:印度尼西亚伊斯兰银行
本研究使用线性回归分析来评估伊斯兰银行信贷组合在宏观经济冲击下的脆弱性及其对npf的影响。从OLS、ARIMAX和误差修正模型(Error Correction Model, ECM)三个模型中,选择ECM模型为最佳模型。通过使用蒙特卡洛模拟,对伊斯兰银行NPF的可能未来价值进行了估计。研究发现,汇率、经济差异、通货膨胀、经济增长和利率对银行信贷风险的影响为正且显著,而通货膨胀对银行信贷风险的影响为负。不良财务(NPF)也估计使用蒙特卡罗模拟使用一百万次试验。结果随后被用于对预计的国家爱国力量进行压力测试。在99%的信心下,不良信贷的最大潜在价值为21%。在95%的置信水平下,NPF不良信用达到了最大值。
