Common equity Tier 1 capital ratio financial

"Common equity Tier 1 capital ratio (6) / (7)"

A bank’s common equity tier 1 (CET1) capital ratio measures the size of its strongest loss-absorbing capital—mainly common shares and retained earnings—relative to the bank’s assets after adjusting those assets for how risky they are (riskier loans count more). Think of it as the safety cushion compared with the weight of risky business; investors use it to judge a bank’s ability to survive losses, meet rules, and sustain dividends or growth.

Risk weighted assets financial

"Risk weighted assets | | | 102,128.2"

Risk weighted assets (RWA) are a way banks and regulators treat different assets as if they carry different levels of risk, assigning each asset a weight based on how likely it is to lose value. Investors use RWA to judge how much capital a bank must keep on hand to absorb losses; higher RWA means the lender needs more capital and may have less room to lend or return money to shareholders. Think of it as packing fragile and sturdy items differently when calculating how much protective padding you need.

Leverage Ratio financial

"Leverage Ratio | | | 5.25 | %"

Leverage ratio measures how much a company relies on borrowed money compared with its own funds or assets, typically expressed as debt relative to equity or total assets. Like a homeowner with a mortgage, higher leverage can amplify returns when business is strong but also raises the chance of big losses or default if revenue falls, so investors use it to judge financial risk and resilience.

Required capital financial

"Required capital (7) X 8%"

capital structure financial

"Information on capital structure of Sumitomo Mitsui Financial Group"

Capital structure is the way a company finances its operations and growth by using different sources of money, such as borrowed funds (loans or bonds) and owner’s equity (investments from owners or shareholders). It’s like a recipe for baking a cake, where the balance of ingredients affects the final product's strength and taste; similarly, the mix of debt and equity influences a company's stability and risk. For investors, understanding a company's capital structure helps gauge how risky it might be to invest or lend money.
