Factors Affecting Banking Capital Buffer on the Indonesia Stock Exchange: A Comprehensive Analysis

The banking capital buffer is a crucial component of a bank's financial stability, serving as a reserve to mitigate adverse economic shocks. In Indonesia, the banking sector has been subject to various regulatory requirements, including the Basel Accord, which sets a minimum capital adequacy ratio (CAR) of 13%. However, banks in Indonesia have consistently exceeded this requirement, with an average CAR of 18.98% during the 2010-2013 period. This study aims to investigate the factors that affect banking capital buffer in Indonesia, using a dataset from the 2012-2015 period.

Understanding Capital Buffer

Capital buffer is the difference between a bank's capital ratio and the minimum CAR set by the central bank. It serves as a capital reserve for banks to deal with various adverse economic shocks, such as credit losses, market volatility, and liquidity crises. The Basel Committee on Banking Supervision (BCBS) has implemented the Basel Accord, which requires banks to maintain a minimum CAR of 13% to strengthen their capital position, reduce regulatory gaps, and consider various bank risks to achieve banking stability and resilience internationally.

Research Methodology

This study uses a panel data approach to analyze the factors that affect banking capital buffer in Indonesia. The dataset consists of 20 banks in Indonesia, with data from the 2012-2015 period. The study employs five variables to analyze the determining factors of capital buffer:

Return On Equity (ROE): This variable measures a bank's profitability, which is an important factor in determining capital buffer.
Non-Performing Loan (NPL): This variable measures a bank's credit quality, which is a critical factor in determining capital buffer.
Lag of Capital Buffer (Bufft-1): This variable measures the previous period's capital buffer, which is an important factor in determining the current period's capital buffer.
Loans to Total Assets (Lota): This variable measures a bank's credit risk, which is an important factor in determining capital buffer.
Bank Size (Size): This variable measures a bank's size, which is an important factor in determining capital buffer.

Results

The results of this study indicate that the capital buffer is significantly influenced by the lag of capital buffer (bufft-1). This finding shows that banks tend to maintain a level of capital buffer similar to the previous period, indicating that banks are careful in managing capital and tend to maintain a safe level of capital buffer to deal with future risks.

The study also found a positive correlation between the bank size (size) and the capital buffer, indicating that larger banks tend to have a higher capital buffer. This may be because larger banks have a wider asset base and require greater capital to cover higher risks.

Furthermore, the study found a negative correlation between ROE, NPL, and Lota on capital buffer. This indicates that banks with higher profitability rates tend to have a lower capital buffer, banks with higher bad credit ratios tend to have a lower capital buffer, and banks with higher loan ratios to total assets tend to have a lower capital buffer.

Deeper Analysis

The findings of this study provide a deeper understanding of the factors that affect banking capital buffer in Indonesia. The lag of capital buffer (bufft-1) is an important factor in determining the current period's capital buffer, indicating that banks tend to maintain a level of capital buffer similar to the previous period.

The positive correlation between bank size (size) and capital buffer indicates that larger banks tend to have a higher capital buffer, which may be due to their wider asset base and higher risks.

The negative correlation between ROE, NPL, and Lota on capital buffer indicates that banks with higher profitability rates, higher bad credit ratios, and higher loan ratios to total assets tend to have a lower capital buffer.

Implications for Banks and Regulators

This study provides some important implications for banks and regulators:

Bank: Banks need to pay attention to the factors that affect capital buffer and manage capital effectively to achieve optimal capital buffer. Banks need to consider strategies to increase profitability, reduce NPLs and Lota, and increase capital buffer.

Regulator: Regulators need to continue to monitor the capital buffer of banks and consider the factors that influence the capital buffer in formulating banking policies. Regulators also need to encourage banks to increase transparency and accountability in capital management.

Limitations and Future Research

This research has several limitations, such as limited research period and limited data. Further research with broader periods and data is needed to strengthen the findings of this research. Additionally, future research can explore other factors that affect banking capital buffer, such as macroeconomic variables, regulatory requirements, and bank-specific characteristics.

In conclusion, this study provides a comprehensive analysis of the factors that affect banking capital buffer in Indonesia. The findings of this study have important implications for banks and regulators, highlighting the need for effective capital management and transparency in capital buffer.
Frequently Asked Questions: Factors Affecting Banking Capital Buffer on the Indonesia Stock Exchange

In our previous article, we discussed the factors that affect banking capital buffer in Indonesia, using a dataset from the 2012-2015 period. In this article, we will answer some frequently asked questions related to the topic.

Q: What is the Basel Accord, and how does it relate to banking capital buffer?

A: The Basel Accord is a set of international banking regulations that aim to strengthen the capital position of banks and reduce regulatory gaps. The Basel Accord requires banks to maintain a minimum capital adequacy ratio (CAR) of 13%, which is the ratio of a bank's capital to its risk-weighted assets.

Q: What is the difference between capital buffer and capital adequacy ratio (CAR)?

A: Capital buffer is the difference between a bank's capital ratio and the minimum CAR set by the central bank. It serves as a capital reserve for banks to deal with various adverse economic shocks. CAR, on the other hand, is the minimum capital requirement set by the central bank.

Q: What are the factors that affect banking capital buffer in Indonesia?

A: The study found that the lag of capital buffer (bufft-1), bank size (size), return on equity (ROE), non-performing loan (NPL), and loans to total assets (Lota) are the factors that affect banking capital buffer in Indonesia.

Q: What is the significance of the lag of capital buffer (bufft-1) in determining the current period's capital buffer?

A: The lag of capital buffer (bufft-1) is an important factor in determining the current period's capital buffer, indicating that banks tend to maintain a level of capital buffer similar to the previous period.

Q: What is the relationship between bank size (size) and capital buffer?

A: The study found a positive correlation between bank size (size) and capital buffer, indicating that larger banks tend to have a higher capital buffer.

Q: What is the relationship between ROE, NPL, and Lota on capital buffer?

A: The study found a negative correlation between ROE, NPL, and Lota on capital buffer, indicating that banks with higher profitability rates, higher bad credit ratios, and higher loan ratios to total assets tend to have a lower capital buffer.

Q: What are the implications of this study for banks and regulators?

A: The study provides some important implications for banks and regulators. Banks need to pay attention to the factors that affect capital buffer and manage capital effectively to achieve optimal capital buffer.

Q: What are the practical implications of this study for banks and regulators?

A: The study provides practical implications for banks and regulators, highlighting the need for effective capital management and transparency in capital buffer. Banks need to consider strategies to increase profitability, reduce NPLs and Lota, and increase capital buffer.
