Woori Financial Group Inc.

Most of its revenue comes from interest earned on loans and other credit extended to customers, funded mainly through deposits. A smaller share comes from fees for services such as foreign exchange, trade finance, derivatives, investment banking, asset management and insurance.

It scales mainly by growing the size of its balance sheet, taking in more deposits and extending more credit, a process that its own capital base and its regulator's capital requirements both enable and limit, and the years on file show it steadily building that capital base through consistently positive earnings and a steadily growing book value. Its filings also describe scale coming through a wide branch, ATM and digital network at home and a presence spread across many countries abroad, rather than through adding separate, self-contained units.

Its funding depends mainly on customer deposits, most of which, its filings state, can be withdrawn on demand or fall due within a year. It also depends on those depositors continuing to renew their deposits at maturity rather than withdrawing them, a pattern its filings say has held historically.

Depositors depend on it to hold and move their money, while individual and corporate borrowers, including the small and medium-sized businesses its filings say it has lending relationships with, depend on it for credit. In its securities business, issuers of asset-backed debt and the institutional investors who buy that debt also depend on it to arrange, and in some cases provide liquidity for, the transaction.

This way of taking in funding and extending credit for a margin is a shape many other companies run in similar form, so the underlying structure is common rather than unique to this group. Its own filings point to its retail customer base, distribution network, capital base, management experience, small business lending relationships and risk-management practices as strengths, though CompanyGraph has not independently verified that rivals lack these or cannot build similar ones.

Its filings point to regulatory capital requirements as a limit on how far it can grow: expanding its lending depends on holding or raising enough capital to satisfy its regulator, and it states that additional capital may not always be available on favorable terms, or at all. It also states that falling short of those requirements can bring penalties as severe as suspension or loss of its banking license.

Its filings name reliance on short-term customer deposits as a specific vulnerability: because most of that funding can be withdrawn on demand or comes due within a year, a broad wave of withdrawals, or depositors failing to renew those deposits when they come due, could strain its liquidity and force it to replace that funding with more expensive alternatives.

It operates under the supervision of named Korean financial regulators and several overlapping banking and financial-markets statutes. Its operations also extend through branches and subsidiaries across many other countries, which its filings name, so conditions and rules in those markets act on it as well, beyond its home regulator.
