Abstract

General Background: In the wake of adopting IFRS 9, commercial banks are required to apply a forward-looking approach in estimating credit losses, aiming to enhance financial transparency and risk management. Specific Background: Iraqi private commercial banks have faced significant challenges in adapting to this paradigm, particularly due to volatile economic conditions and operational inefficiencies. Knowledge Gap: Despite IFRS 9's relevance, limited empirical analysis exists on how expected credit losses (ECL) affect profitability in emerging markets like Iraq. Aims: This study investigates the impact of ECL on net profit among a sample of Iraqi private commercial banks between 2021 and 2023, focusing on compliance with IFRS 9 and its effect on financial performance. Results: The findings reveal that higher ECLs significantly reduce net profits, especially in banks with high default rates and inconsistent risk practices. Additionally, discrepancies in IFRS 9 compliance contributed to inaccuracies in loss estimations. Novelty: Unlike previous research, this study provides a detailed sector-specific empirical analysis linking regulatory standards to profitability outcomes in a high-risk economic environment. Implications: Strengthening compliance with IFRS 9, enhancing disclosure, and reforming regulatory provisions could mitigate the adverse effects of ECL on profit, thereby reinforcing financial stability in Iraq's banking sector.Highlights: IFRS 9 impact – Adoption of IFRS 9 led to a forward-looking loss model, affecting how banks recognize credit losses and report profits. Profit reduction – Higher expected credit losses correlate directly with decreased net profits, especially in banks with weak credit risk management. Disclosure gaps – Variations in compliance and lack of transparency in financial disclosures hinder effective decision-making and risk evaluation Keywords: Expected Credit Losses, IFRS 9, Net Profit, Private Banks, Credit Risk

Abstract

General Background: The volatility of foreign exchange rates poses significant risks to financial stability, especially in Islamic banking, where conventional hedging instruments are often non-compliant with Sharia principles. Specific Background: In Indonesia, Islamic banks increasingly engage in international transactions, amplifying exposure to currency fluctuations without sufficient Sharia-compliant risk mitigation tools. Knowledge Gap: Despite various studies on individual hedging instruments, a comprehensive synthesis evaluating the effectiveness and implementation challenges of Islamic hedging in Indonesia has been lacking. Aims: This study aims to systematically review the application of three primary Islamic hedging instruments—wa’d-based forward, cross currency swaps, and natural hedging—in Indonesian Islamic banks, and assess their effectiveness and constraints. Results: The findings reveal that wa’d-based forward is the most frequently utilized instrument, offering Sharia-compliant mitigation of exchange rate risk. However, limited market liquidity, regulatory ambiguity, and low technical capacity hinder optimal implementation. Novelty: This study provides the first consolidated evaluation of Islamic hedging in Indonesia using a Systematic Literature Review (SLR) method, identifying thematic research trends, barriers, and regulatory gaps. Implications: The results suggest the need for policy reform, international collaboration, and product innovation to strengthen Indonesia’s Sharia-compliant financial risk management ecosystem.Highlight : Islamic hedging tools like wa’d-based forward and CCS reduce currency risk while complying with Sharia law. Implementation in Indonesia faces challenges such as low market liquidity and limited regulatory support. Compared to Malaysia, Indonesia needs stronger innovation and collaboration to advance its Islamic hedging practices.

Abstract

Background: Heart rate (HR) is a vital physiological indicator influenced by multiple internal and external factors. Specific Background: Urban environments, lifestyle habits, and occupational stressors have raised concerns about their impact on cardiovascular health. Knowledge Gap: Despite existing literature on isolated factors like smoking or noise, limited research has examined the combined effects of environmental and physiological variables on HR among healthy individuals in real-world settings. Aims: This study investigates how physical factors—age, gender, smoking, hypertension, sleep position, noise-induced stress, and ambient temperature—affect HR among healthy individuals in Erbil, Iraq. Results: Data from 120 subjects reveal that smoking, noise exposure, prone sleeping, and elevated temperatures significantly increase HR, while athletes and hypertensive individuals tend to have lower HRs. No significant HR differences were observed between sexes across age groups. Novelty: This study uniquely integrates multiple environmental and physiological factors, demonstrating how combined exposures impact cardiovascular dynamics, an area underexplored in Middle Eastern populations. Implications: The findings underscore the need for targeted public health interventions addressing modifiable risk factors (e.g., noise and heat exposure) to mitigate cardiovascular strain in urban settings.Highlights: Smoking and stress significantly elevate heart rate, particularly in younger males and in noisy environments. Temperature extremes (e.g., bakery conditions) raise heart rate, indicating a strong link between ambient heat and cardiovascular response. Posture during sleep influences heart rate, with the supine position associated with the highest readings. Keywords: Heart Rate, Temperature, Stress, Smoking, Hypertension
