Which of the following was first introduced with Basel III?

The introduction of a global framework for bank liquidity regulation is indeed a significant aspect of Basel III. This framework aimed to enhance the banking sector's ability to withstand financial stress by ensuring that banks maintain adequate liquidity. The key components include the Liquidity Coverage Ratio (LCR) and the Net Stable Funding Ratio (NSFR), which were established to ensure that banks have enough liquid assets to survive acute financial disruptions over short and long-term periods.

Basel III was developed in response to the financial crisis of 2007-2008, which highlighted the critical need for improved liquidity management within financial institutions. By implementing this global framework, banks are now required to hold a buffer of liquid assets and maintain a sustainable level of funding relative to their assets, effectively promoting a more resilient banking system.

The other options, while pertaining to Basel III, do not focus directly on the primary new framework for liquidity regulation. The capital adequacy ratio and risk-weighted asset calculations are adjustments to existing metrics rather than new frameworks, while anti-money laundering guidelines fall outside the specific financial regulations aimed at capital and liquidity that Basel III focused on.
