What is the main responsibility of the International Accounting Standards Board?

The main responsibility of the International Accounting Standards Board (IASB) is to produce accounting standards that have global acceptance. The IASB aims to create a consistent framework for financial reporting across different countries, which is essential for international investors and businesses that operate in multiple jurisdictions. By establishing International Financial Reporting Standards (IFRS), the IASB helps ensure that financial statements are comparable and understandable, enhancing transparency and building trust among investors, regulators, and the general public.

As companies increasingly operate on a global scale, having a unified set of accounting standards facilitates cross-border transactions and reduces the complexity associated with complying with different national standards. This effort is crucial for promoting global market stability and efficiency.

The other options pertain to different areas of financial regulation and governance. While writing tax regulations focuses on taxation rules within specific jurisdictions, training auditors and overseeing bank financials target more specialized roles and functions that do not encompass the IASB's primary mission of setting universal accounting standards.
