چکیده

در این پژوهش بازده سرمایه تعدیل‌شده به ریسک (RAROC) به‌عنوان یک شاخص سنجش عملکرد اقتصادی و تعدیل‌شده به ریسک تبیین و برای اولین‌بار براساس روش جدید مبتنی بر مطالعات اخیر برای همه بانک‌های پذیرفته‌شده در بورس اوراق بهادار تهران و فرابورس ایران در بازه زمانی سالهای 1391 الی 1398 محاسبه گردید. روش محاسبه این شاخص در این پژوهش یکی از وجوه تمایز آن به شمار می‌رود. در گام بعد ضمن معرفی شاخص‌های کملز (CAMELS) و تبیین اهمیت آن‌ها، اثرشان بر بازده سرمایه تعدیل‌شده به ریسک بر اساس مدل رگرسیون خطی چند متغیره و رویکرد پانل دیتا، مورد سنجش قرار گرفت. بر اساس یافته‌های پژوهش، بسیاری از بانک‌ها علی‌رغم افشای سودخالص درصورت-های مالی خود، از حیث این شاخص در وضعیت مناسبی قرار ندارند. همچنین براساس مدل اجراشده، اثر کفایت سرمایه، کیفیت مدیریت، کیفیت سود و کیفیت نقدینگی بر بازده سرمایه تعدیل‌شده به ریسک در بانک‌ها معنی‌دار تلقی شد، بدین معنا که با بهبود این شاخص‌ها می‌توان RAROC را نیز بهبود بخشید. از طرف دیگر رابطه‌ای بین کیفیت دارایی‌ها و حساسیت نسبت به ریسک بازار با این شاخص یافت نشد.

چکیده [English]

In this Research, The Risk-Adjusted Return on Capital (RAROC), as economic performance measurement and risk-adjusted index, was introduced and has been calculated for all the registered banks in the Tehran Stock Exchange and Over-the-Counter Market of Iran, based on contemporary methods which were extracted from earlier researches. The way in which this variable was calculated is one of the distinctions of this research. The period of this research is 8 years, from 2012 to 2019. At the next stage, the CAMELS indicators were introduced and their importance were declared. Then, the impact of these indicators on RAROC were assessed by a multiple linear regression model and Panel Data approach. The results illustrated this fact that there are numerous banks which even disclose net income in their financial statements, while based on RAROC index are not financially as safe as they seem.  Also, it has been concluded that Capital Adequacy ratio, Management Quality, Earnings Quality, and Liquidity Quality affect the RAROC. Meaning that, by improving those indicators, RAROC index will be enhanced. On the other hand, Asset Quality and Sensitivity to Market Risk have no significant effect on the RAROC.
