IFRS Adoption and Performance of Stock Markets: A Comparative Analysis of Frontier Stock Markets in Sub-Saharan Africa

The International Financial Reporting Standards (IFRS) is a set of global accounting standards that tries to provide truer and fairer accounting figures by recommending more realistic measurement and recognition criteria, increasing the disclosure of relevant information, and increasing the comparability of financial statements across borders. Most of the literature on IFRS adoption addresses its impact on the value relevance of accounting figures but ignores the wider picture in terms of impact on stock market performance. The few studies that address IFRS adoption and stock market performance focus on advanced economies and lack proper theoretical underpinning. This study addresses the impact of IFRS adoption on stock market performance in Sub-Saharan Africa. The study applied the autoregressive distributed lag model to test the research hypotheses. The Johannesburg, Nigerian, and Nairobi stock exchanges were selected as the sample markets because they constitute the major frontier markets for foreign investors wishing to penetrate the Sub-Saharan African market. The sample period was from 1990 to 2020. The results of the study showed that IFRS adoption had a positive and significant impact on market efficiency and size for all the selected countries. IFRS adoption had a positive and significant impact on market liquidity in Kenya only. The study recommends that IFRS adopters should implement stock market policies that encourage the participation of foreign investors following the increase in financial statements comparability brought about by IFRS adoption.
