Under the Basel III regulatory framework, CoCos are designed to act as a crisis aversion tool for banks, offering an early intervention mechanism before the institution reaches the point of non-viability. To qualify as a capital instrument, CoCos must include specific trigger points that are meant to detect the onset of financial distress. Such triggers, notably the 'going-concern' trigger, are set to activate before the risk of insolvency becomes imminent. The 'going-concern' trigger usually involves a threshold set in relation to Core Equity Tier 1 (CET1) capital - an essential measure of a bank's financial strength - indicating how much CET1 capital must be preserved relative to the bank's Risk-Weighted Assets. When the bank's CET1 capital falls below this value, CoCos convert to equity or get written down, automatically bolstering the bank's capital and helping to maintain its solvency without resorting to external rescue measures.

A is incorrect. CoCos do not need to wait for the bankruptcy of the bank to convert into equity. The trigger mechanisms are designed to strengthen a bank's capital position preemptively, often well before insolvency proceedings might begin.

C is incorrect. CoCos are not required to provide fixed, cumulative dividends. In fact, CoCo terms typically include the possibility of suspending dividend payments under certain scenarios to preserve capital.

D is incorrect. CoCos under the Basel III framework are often structured as perpetual instruments, meaning they do not necessarily have a specified maturity date that aligns with traditional senior debt. The perpetual nature of CoCos reinforces their role in providing continuous capital support.

Things to Remember

• CoCos (Contingent Convertible Bonds) are a type of hybrid capital instrument that can absorb losses in times of financial stress.
• CoCos are designed to convert into equity or be written down when specific trigger points are breached, helping to strengthen a bank's capital position.
