ABSTRACT
This study constructs a financial stability index for the Islamic financial system of Indonesia using the dynamic factor model and then links it to economic performance employing a nonlinear autoregressive distributed lag (NARDL) model.
The financial stability index constructed from a broad range of macrofinancial variables captures well the 2008-2009 global financial crisis and the 2020-2021 COVID 19 pandemic crisis The most significant results suggest that positive and negative shocks in Islamic financial stability in the long run increase and decrease economic performance.
The quantile regression results also demonstrate that Islamic financial stability is statistically significant throughout all quantiles in promoting economic performance, although it plays a greater role at lower quantiles and diminishes when the economic performance is at a high level.
Our results highlight that the stability of the Islamic financial system deepening would positively enhance economic performance.

Effect of Islamic Financial System Stability on Economic Performance in Indonesia
INTRODUCTION
The issue of financial instability of the conventional financial system from different angles and perspectives have received attention before the 2007-2009 global financial crisis.
The crisisAo immense scope and ramifications have highlighted the long-standing and difficult problem of Authe hunt for financial stabilityAy.
the financial system is unstable, are there any Aueffective solutionsAy or Augreatly moderated structural reformsAy that may be pursued? With respect to this question.
Islamic financial institutions (IFI.
and the principles that guide their operations have attracted a lot of attention throughout this contentious debate.
However, most of the pre-crisis studies, if not all of them, are theoretical and based on an Auabstract model.
Ay They note that Islamic financial system is primarily centred on equity and participatory forms of funding.
The crisisAos explosion has sparked empirical investigations to capture the actuality of these institutions in practice.
While Islamic finance and conventional finance both serve a similar purpose, there are significant variations between the two systems.
Osei and Kim .
argue that although the financial sector benefits economic growth, the impact of additional financial development on growth becomes minimal.
As a result, the nonlinear relationship exists, and achieving an ideal degree of financial development is critical for economic growth.
Social justice, inclusivity, and resource sharing between the rich and the poor are at the heart of Islamic Finance Sharia Law.
There are two ways that Islamic finance handles the issue of Aufinancial inclusionAy or Auaccess to financing.
Ay The first channel encourages risk-sharing agreements as a feasible substitute for traditional debt-based funding.
To increase financial inclusion, the risk-sharing financial instruments can provide microfinance and microinsurance that adhere to Islamic law.
The second channel is redistribution of wealth in society via Zakah.
Sadaqah, and Waqf, which are risk-sharing tools for eradicating poverty and enhancing social welfare.
Financial development is more likely to occur if everyone has access to financing, the law encourages greater risk sharing, and income is distributed equally.
Sharia Law thereby protects citizens from reckless behaviour and supports financial stability and economic growth.
According to the Islamic Finance Development Report .
, the top five countries in relation to Islamic Finance are Malaysia.
Indonesia.
Bahrain.
United Arab Emirates and Saudi Arabia.
Indonesia has displayed one of the most notable improvements in the Islamic Finance Development Indicator (IFDI) in 2020, moving into second place for the first time due to its high knowledge and awareness ranking.

had a robust resurgence as economies recovered from a challenging 2020 brought on by the worldwide pandemic and decreased oil prices.
IFIs were extremely cautious when setting aside money for financing loss in 2020.
Charges were significantly lower in 2021, and several institutions released reserves, which improved outcomes.
Islamic banksAo net profits increased by more than 50% in 2021, with banks in the Gulf recording especially impressive performance.
Customer deposits kept growing, fuelling the expansion of finance portfolios.
IFIs also recognised the value of technical and digital initiatives that reduced operating costs.
Nevertheless, the IFIs stability issue remains an important question to be addressed.

Vol.
Number 3, 2022 This study examines the effect of Islamic financial stability on economic performance in Indonesia, a country that has the highest Islamic population in the world.
Islamic financial system is getting popular and improving since the last few years.
The stability of the Islamic financial system is crucial, especially in channelling funds from surplus units to deficit units, consequently, promoting economic performance and reducing poverty.
Indonesia is an interesting case to analyse the effect of Islamic finance issue on economic development.

As such, it is important to analyse the financial stability in Indonesia.
Given the complexity of contemporary financial systems and current worldwide trends, financial stability has been linked to a variety of issues that are generally related to the smooth operation of financial The most complete conceptual framework for characterising financial stability is provided by Allen & Wood .
They contend that any policy meant to create financial stability must have the general welfare as one of its primary They also emphasise how crucial it is for financial stability to be quantifiable and how it must be governed by a certain governmental body.
This makes it possible for competent policymakers to respond quickly to the first indications of economic distress and loss of stability.
The organisation in charge of preserving financial stability must have sufficient power to address problems related to it.

Effect of Islamic Financial System Stability on Economic Performance in Indonesia In the case of Indonesia, the share of Islamic finance is increasing based on the Fitch Rating .
With a growth rate of 7.
5% in September 2021.
Islamic banksAo gross financing increased faster than that of their conventional counterparts .
onventional banks: 1.
8 percen.
The proposed conversion of three regional Indonesian lenders to Sharia banks in 2022 is expected to boost the market share of Sharia banks.
According to Fitch Rating projections, these conversions will increase the proportion of Sharia financing in the banking sector from 7.
1 percent at end of September 2021 to around 9 percent.
The financial profiles of the Islamic Sharia banks increasingly more closely resemble those of their conventional competitors.
They were able to keep their non-performing financing ratio at 3.
1 percent at the end of September 2021 .
onventional banksAo non-performing loan ratio was 2 percen.
, thanks to their focus on consumer financing (September 2021: 50 percent of total financing.
conventional: 26 percen.
, which fared better during the At the end of September 2021, their average capital adequacy ratio of 25% indicated that their capitalization was comparable to that of their traditional peers, and their average return on assets of 1.
6% did the same.
Another issue is related to the interest rate sensitivity in Indonesia where Islamic banksAo equivalent rates are lower than conventional banksAo interest rates.
As shown in Figure 2, the conventional banks have higher interest rates compared to Islamic banks especially for deposit rate, although the credit rates of both banks tend to be equal.
However, from the crediteeAo side, they tend to go to Islamic banks because the credit agreement is clearer from the beginning, and the Islamic banks is basically a flat rate.
6 In contrast, the interest rate of bank credits from conventional banks is floating, and hence maybe quite volatile or risky especially for the long run period.
However, since conventional banks are dominant players with extensive networks and services compared to the Islamic ones, no wonder if the latter banks face funding constraint issue.
Therefore, the sensitivity of the interest rate changes between conventional and Islamic banks pose some challenges to Indonesian financial markets and institutions.
If the central bank namely Bank Indonesia implements low interest rate policy, the conventional banks will charge low interest rate too.
Nevertheless, for the Islamic banks, they give higher equivalent rate .
erformance from profit and los.
Therefore, this condition is heterogeneity across the financial system whereby some can provide higher, and others can provide lower interest rates.
Furthermore, the public has different perception towards the interest rate, whether the depositors are willing or prefer to save in conventional or Islamic Conventional banks are more towards profit-oriented objectives, and hence may optimize their funds invested in money markets in a very short term.
And, as consequence, they may also expose to higher default risks, or at least more volatile returns.
While shariah banks are more focused on underlying transactions namely credit disbursement, as well as limited options for financial market products notably Islamic bonds and stocks, while investing in derivative products 5 In the concept of Islamic banking, there is no such interest rate relationship, and they mainly use the profit and lost sharing principle as instead.
Commonly it is called as an equivalent rate, instead of interest rate .

Islamic Banks and Conventional Banks Interest Rates This study contributes to the literature in four important aspects.
First, despite the rapid development of Islamic financial markets in Indonesia in recent years, it is interesting to examine the financial stability by means of constructing its index using the dynamic factor model (DFM).
To our knowledge, this is the first study formally constructing the Islamic financial stability index for Indonesia.
8 Second, since the DFM method has a greater coverage of areas in the construction of financial stability index, it can be useful as one of the leading indicators in predicting the business cycle and serve as a signal for timely policy actions.
Third, the financial stability indexes are used to relate with economic performance in Indonesia using the non-linear autoregressive distributed lagged (ARDL) models.
The NARDL 7 This law is effective since 22 September 2005 and IDIC has been officially operating since then.

LITERATURE REVIEW
Financial stability is considered a dynamic process that promotes financial system expansion rather than strictly limiting natural swings and changes.
Both macro and micro techniques are suggested by Houben et al.
and Mohamed et al.
to understand the causes of financial instability.
According to the macroeconomic perspective, instability is believed to be caused by two main factors.
These are the sharp price swings and the overleveraged state of the economy.
They contend that building wealth and increasing fixed assets are among the primary goals of finance for individuals, businesses, and governments, and that this leads to an observed rise in the prices of the related transferable claims.
Thus, the eventual realisation of these claims is associated with excessive borrowing and investment.

The findings also demonstrate that there is a sizable gap between Islamic finance theory and While actual studies are still inconclusive, theoretical studies assert the AusuperiorityAy of the Islamic financial system based primarily on equity and participatory ways of funding.
Based on data pertaining to specific Islamic and commercial banks in 19 banking systems with a significant presence of Islamic banking, the relative financial health of Islamic banks is evaluated empirically.

However, a more thorough examination shows that greater market dominance is bad for both state-owned banks and smaller privately held banksAo capacity to maintain their financial soundness.
To increase financial stability, they contend that market power should be increased in large private banks while being reduced in small private banks through competition.

It also evaluates how much less sensitive to financial imbalances targeting central banks are as compared to those using alternative policy measures.
The analysis reveals that monetary policy in target countries is considerably more sensitive to financial risks based on a sample of 26 emerging nations, including 13 targeters.
However, the financial sector looks to be more vulnerable to targeters despite better central banksAo responses to financial imbalances.
Thus, the conclusion casts doubt on the notion that central banks can ensure financial system stability through the setting of policy interest rates.
Instead, it recommends that the primary goal of monetary policy should continue to be the control of inflation, with the goal of financial stability being handled by a .

However, since 2010, the rate of multi-factor productivity development has decreased, a trend that has been furthered by weaker global growth.
Some of those challenges have been successfully countered by a series of interest rate reductions.
However, supporting monetary policy will not be enough to sustain long-term growth and raise inflation risks in the absence of additional structural reforms to boost productivity growth.

Effect of Islamic Financial System Stability on Economic Performance in Indonesia Assessment of explanatory power of a financial stability index Selected financial indicators are utilised to estimate the factor, which is an adaptation of Stock and WatsonAos .
The estimated factor calculates the average changes in the group of chosen financial indicators.
Following that, the calculated factorAos explanatory power is evaluated in relation to the movement of the Indonesian economic cycle.
A financial stability indexAos capacity to predict the business cycle is examined using formal prediction tests.
In particular, in-sample and out-of-sample analyses are employed to evaluate the financial stability indexAos explanatory power.

The Chow breakpoint test is used to check the stability of the coefficients of Z over the sample period to detect structural stability in the coefficients of Z in Equation .
In addition, structural changes or crises may occur over the sample period, such as the global financial crisis of 2007Ae2008, which had negative effects on the Indonesian economy in the third quarter of 2008.
There is a danger that one will either overestimate or underestimate a modelAos Therefore, the out-of-sample predictive test is run to assess the financial stability indexAos ability to predict the business cycle.
By estimating Equation .
recursively over the forecast period with various lag lengths, where the lags of k and p are selected at each sample period using SIC to obtain the values of root mean squared error (RMSE), pseudo out-of-sample forecasting is used to achieve this purpose.

The performance of the alternative model is calculated using a relative RMSE to the benchmark model.
a relative RMSE with a value lower than 1 indicates that the alternative model performs better than the benchmark model, or vice versa.

Earlier research on the effect of financial development on economic performance uses linear models.
The autoregressive distributed lag (ARDL) model of Pesaran et .
and Pesaran et al.
, which is part of the linear specification, is unable to account for the disparate effects of financial stability on economic performance.
Thus, this study extends the ARDL model to the non-linear ARDL (NARDL) model developed by Shin et al.
to capture the complexity of the financial stability on economic performance in Indonesia.
The NARDL model allows us to determine whether positive and negative financial stability shocks have any impacts on short and long run economic performance.

augmented with asymmetric coefficients of NARDL is as follows:

FSIndext and FSIndext- constitute the partial sums of positive and negative changes in the financial stability, respectively.
They are specified as follows:

The NARDL model is performed irrespective of whether the variables are integrated in order 0 or 1 (I.
or I.
However, it cannot be applied if one of the variables is I.
Hence, the unit root tests (Augmented Dickey Fuller and Phillip and Perro.
are conducted to test the order of integration of the variables.
Additionally, to examine the cointegration among the variables, the bound test approach introduced by Pesaran et al.
and Shin et al.
is performed.
The null hypothesis of no cointegration a1 = a2 = a3 = a4 = a5 = a6 = a7 = 0 is tested using the Wald F-test.
According to Shin et al.
, there are four possible specifications: .
longrun and short-run asymmetry, .
long-run asymmetry and short-run symmetry, .
long-run symmetry and short-run asymmetry, and .
long-run and short-run An advantage of using the asymmetric ARDL model is that it allows for asymmetries in the financial stability-economic performance relationship in the long-run as well as the short-run.
Among the authors who used the NARDL estimation method are Wakimin et al.
Sanusi et al.
, and Long et .
in their data analysis.
Recent years have seen a rise in the popularity of the NARDL technique, which has been applied to several sectors, including agricultural economics, real estate economics, environmental economics, and energy economics.

This means that Islamic financial stability is conducive to promote economic performance and proves that the roles of Islamic finance in channelling funds and other tasks in Indonesia and that Islamic financial stability is beneficial to promoting economic performance.
Nevertheless, when the economic performance has reached at the high level, the role of Islamic finance stability diminishes as shown in the coefficients become smaller at higher quantile levels.

Coefficients of Islamic Financial System at Different Quantiles CONCLUSIONS As the allocation of financing can support national economic growth, financial system stability is crucial for it to operate effectively and efficiently while preserving resilience to internal and external vulnerabilities.
This study examines the role of Islamic financial system stability in influencing economic performance in Indonesia, using quarterly data from 2006:Q1 to 2021:Q4.
The stability index is constructed utilizing the DFM that consists of three alternative models and the selection of the final financial stability index is based on various criteria used in the Motivated by most studies in the field of financial stability that have only focused on conventional financial system, this study contributes to the literature on the Islamic financial system stability issue using a non-linear ARDL approach to capture the positive and negative stability effects on economic performance.
A variety of forecasting tests, including in-sample analysis, pseudo out-ofsample forecasting analysis, and forecast rationality, are used to evaluate the financial stability index for its capacity to explain the Indonesian business cycle.
The empirical findings demonstrate that the Islamic financial stability indexes constructed capture well the 2008/2009 global financial crisis and the recent 20202021 COVID 19 pandemic economic recession.
The empirical results of NARDL reveal significant asymmetries in the impact of Islamic financial stability on short- and long-term economic performance.
The results suggest that positive and negative shocks to Islamic financial system stability affect economic performance differently in the short and long run, thus demonstrating the inadequacy of linear models to capture the effect of Islamic financial stability on economic The positive Islamic financial stability shocks have a positive and more pronounced impact on economic performance than negative shocks in the long-term.
Specifically, a significantly positive impact of positive Islamic financial stability shocks on economic performance demonstrates that Islamic financial system facilitation is an appropriate policy to address economic performance in Indonesia.
On the contrary, negative shocks of Islamic and conventional Effect of Islamic Financial System Stability on Economic Performance in Indonesia financial systems may reduce economic performance in the long run, indicating the importance of improving macroprudential policy and supervision for Islamic financial stability in Indonesia.
Our research has important implications for the continuing discussion over the ideal macroprudential and monetary policy mix to achieve higher economic growth, as well as whether monetary policy should address financial stability in addition to macroeconomic stability.
There has not been much research done on the interaction between different macroprudential tools and monetary policy.
This is crucial because, despite recent advancements, there is still a great deal of uncertainty surrounding the effectiveness of some of these instruments in addressing financial stability issues, as well as the degree to which they affect banksAo incentives to engage in excessive lending over the cycle and regulatory arbitrage, their market signalling effects, and hence, economic performance.
leave these issues for future research.
