Abstract

This study examines the effectiveness of various liquidity proxies in distinguishing between Investment Grade (IG) and High Yield (HY) bonds within the Indonesian corporate bond market. Utilizing logistic regression models across a dataset of 30,738 observations for IG bonds and 176 observations for HY bonds, we evaluated the impact of six liquidity proxies: Range Measure (RG), Hui Heubel ratio (HH), Market Share (MS), Interquartile Range (IR), Imputed Roundtrip Cost (IRC), and Trading Volume (TV). The findings reveal that the Imputed Roundtrip Cost (IRC) is the most reliable indicator of liquidity, demonstrating a significant negative relationship with the likelihood of a bond being classified as IG. This suggests that higher IRC values, which represent higher transaction costs, are associated with lower liquidity. In contrast, the other proxies, including the Hui Heubel ratio, did not show consistent or significant impacts in line with the hypotheses. The study concludes that IRC is the best measure for assessing liquidity in the Indonesian corporate bond market.

Abstract

This study aims to compare the disclosure of Value at Risk (VaR) in market risk prediction among banks in Indonesia. By employing comparative and analytical methods, this research examines the effectiveness of VaR disclosure as a market risk prediction tool. Through the evaluation of VaR models disclosed by Indonesian banks and their comparison to a parametric model using asymmetric GARCH volatility for Variance Covariance Value at Risk, this study identifies the extent to which VaR disclosure can be relied upon to predict market risk. This research contributes to the understanding of risk management practices in the Indonesian banking sector and offers recommendations for improving market risk prediction accuracy through more effective VaR disclosures.

Abstract

Previous research has shown mixed results regarding herding behavior in Indonesia. Furthermore, this article analyzes herding behavior in the Indonesian capital market, especially in the conditions before and after the closure of the investor's domicile code as of June 27 2022, by the Indonesian Stock Exchange (IDX). This regulation concerns the closing of foreign and domestic broker codes, which are considered capable of causing herding behavior. Additionally, investor sentiment was also reviewed as a factor that might be contributed to the mixed results of herding behavior in Indonesia. A sample of 607 companies before domicile code closure and 681 companies after domicile code closure were tested using a combination of CSSD and CSAD. The two approaches used to measure show non-significant results of herding both pre and post-closure of domicile code. Investor sentiment was also not seen as a factor that contributed to herding since herding is also non-significant during low or high sentiment before and after the domicile code's closure. Different methods and influencing factors should be considered for further research.

Abstract

This study examines the effect of investor attention during the Initial Public Offering (IPO) period on the stock prices volatility after the shares are listed and traded on the Indonesia Stock Exchange (IDX). This study uses data on the shares of issuers who have conducted an IPO on the IDX after the implementation of the electronic Initial Public Offering (e-IPO) mechanism, with the aim of being able to capture the phenomenon of retail investor behavior. The method used in this study is the regression method. This study shows that the level of investor attention during the IPO period influences the stock price volatility on short-term dan medium-term investment horizon.

Abstract

This research explores how inflows of stock and bond portfolios impact the level of volatility in exchange rates, using monthly data from the United States vis a vis seven emerging Asia countries (China Mainland, China Taiwan, The Philippines, India, Indonesia, Malaysia, and Thailand) between 2010 and 2022. The study uses statistical models such as Ordinary Least Square (OLS), Generalized Autoregressive Conditional Heteroscedasticity (GARCH), and Threshold Generalized Autoregressive Conditional Heteroscedasticity (TGARCH). The findings indicate that net stock and net bond flows have a significant impact on exchange rates volatility, and net stock flows have a more significant impact on exchange rates volatility rather than net bond flows..

Abstract

This study evaluates the hedging effectiveness of Indonesia’s national electrical company, PT PLN (Persero), by comparing Ordinary Least Squares (OLS), Generalized Autoregressive Conditional Heteroskedasticity (GARCH), and Dollar Offset models. Using transaction data from 2018-2023, the analysis shows that the OLS model explains 48.8% of the variance in forward rates, indicating high effectiveness. The GARCH model, while capturing dynamic volatility with an average effectiveness of 4.32%, demonstrates the need for advanced models in volatile conditions. The Dollar Offset method, despite its simplicity, shows a moderate effectiveness of 19.03%. Combining these methods can enhance hedging strategies, providing robust risk management. Future research should expand data sources and periods to further validate findings.

Abstract

This study examines the interest rate pass-through mechanism in Indonesia by analyzing how changes in the central bank policy rate are transmitted to commercial bank lending and deposit rates. The research focuses on two monetary policy regimes implemented by Bank Indonesia, namely the BI 7-Day Reverse Repo Rate and the new BI Rate introduced after December 2023. Using monthly time-series data from August 2016 to January 2025, the study employs the Error Correction Model and Mean Adjusted Lag to evaluate both the short-term and long-term dynamics of interest rate transmission. The Johansen Cointegration Test is also applied to identify the existence of long-run equilibrium relationships between the policy rate and banking interest rates. The results show that the pass-through process is asymmetric, with lending rates responding more quickly to policy rate increases than deposit rates do to policy rate decreases. The analysis also reveals variation in the speed and completeness of pass-through across the different policy regimes. Specifically, the new BI Rate demonstrates a shorter lag in transmission, suggesting improved responsiveness of the interest rate channel under the updated framework. These findings highlight the evolving nature of monetary policy effectiveness in Indonesia’s financial system and provide a better understanding of interest rate dynamics in an emerging market context.

Abstract

Measurement of bank failure risk is still a challenging research problem. This study is aimed to measure the Indonesia banks probability of bankruptcywith Model Merton which has the better predictive power and is based on a far stronger financial theoretical frameworkcompared to the popular bankruptcy prediction model which is categorized by Sundaresan (2013) as a theoretical model such as Altman Z-score model and Ohlson 0 score more popular. The study also examine the relationship of bank efficiency and market power with its probability of default. The test results demonstrate that bank efficiency significantly affects the dynamics of bank's default risk.

Abstract

This study analyzes the effect of green innovation on the default risk of non-financial companies in Indonesia and China during the period 2018–2024. Both countries were selected because they have banking-based financial systems but face different environmental challenges. Default risk is measured using a combined accounting-based approach, namely Altman's Z”-Score, and Zmijewski's ZM-Score. The estimation results using the Fixed Effect Model show that in aggregate, green innovation has no significant relationship with default risk. However, when analyzed per country, the effect of green innovation is proven to be significant and negative on default risk in companies in China, while in Indonesia the relationship is not statistically significant. These findings indicate that the effectiveness of green innovation as a financial risk mitigation strategy is greatly influenced by institutional readiness and national policies. This study provides important insights for policymakers and market players in developing countries regarding the importance of supporting the green innovation ecosystem to strengthen financial stability.
