Tier 1 capital
Of a regulated financial institution, the capital level below everything else than gives comfort to the creditors — in particular, its depositors — that those debts will be met. The most obvious type of tier one capital is the institution’s share capital — “tier 1 common equity”. But also is alternative tier 1 capital, also known as AT1, eighty-one, which takes the form of contingent convertible securities (“co-cos”). It became clear in March 2023 when Credit Suisse finally gave up the ghost, that many in the market, including its AT1 investors, didn’t fabulously understand how it worked. (In fairness to them, it wasn’t obvious, even though it was written into the terms and even the title of the AT1 Notes).
