Tier 2 capital is the secondary cushion a bank holds to absorb losses after its core capital is used, made up of items like long-term subordinated debt and certain reserves. Think of it as a backup battery that kicks in only after the main battery fails; it matters to investors because its size and quality affect a bank’s regulatory strength, creditworthiness, and the safety of dividends and bond payments under stress.
Referential Equity financial

basis points financial
"with an estimated impact of 30 basis points on its Tier 2"
Basis points are a way to measure small changes in interest rates or percentages, where one basis point equals 0.01%. For example, if a loan's interest rate increases by 50 basis points, it's gone up by 0.50%. They help people understand tiny differences in rates that can add up over time, making financial comparisons clearer.
