FINS5512 Chap.2 Banking and Intermediation
Banking and Intermediation
Commercial banks transform claim size, maturity, liquidity and credit risk. This chapter maps sources and uses of funds, distinguishes balance-sheet from contingent off-balance-sheet business, and separates capital from liquidity.
Its worked method converts exposures into risk-weighted assets before applying the materials available hered Basel II total and Tier 1 percentages, while its diagnosis explains why adequate capital does not eliminate refinancing stress. Keep contingent claims beside the balance sheet so commitments are never treated as invisible.
Read every bank scenario through sources, uses and contingencies.
Deposits, wholesale debt, hybrid capital and shareholder funds explain how the institution is financed; liquid assets, securities and loans explain where those funds are placed. An off-balance-sheet guarantee or commitment can still create a future funded claim, so locate its conversion into a credit-equivalent amount before assuming it has no capital consequence.
For credit-risk capital, multiply each exposure by its stated weight and add the weighted amounts before applying total or Tier 1 percentages. A zero contribution to this base does not mean an asset is free from market, liquidity or operational risk. Next, separate loss absorption from cash availability. Capital supports creditors when asset losses exceed current earnings.
Liquidity supports payments when deposits leave, commitments are drawn or replacement funding disappears. A long mortgage may ultimately repay in full and still be unable to meet an immediate withdrawal. Regulation should be matched by function rather than recited as a list: system stability and payments, prudential supervision, conduct and consumer protection, and competition address different failures.
In a written diagnosis, state the balance-sheet item, the shock, the immediate value or cash effect, the relevant buffer or control, and the residual exposure. Add a time horizon to that chain because a daily outflow, a thirty-day stress and a one-year stable-funding test answer different questions. If a contingent claim is involved, show the conversion step before weighting it.
If a rate or currency move is involved, identify the position that reprices. That structure distinguishes a borrower default from a funding run, an internal process failure and a market-rate movement, even when all four reduce confidence in the same institution.

Calculate risk-weighted assets and capital
- +1Apply each risk weight: $0m, $4m, $20m and $18m.
- +1Total risk-weighted assets are $42m.
- +1Total required capital is 8% of $42m, or $3.36m.
- +1Tier 1 capital is 4% of $42m, or $1.68m.
Key terms
- Asset transformation
- Changing the size or form of claims between borrowers and savers.
- Risk-weighted assets
- Exposures measured after relevant credit-risk weights are applied.
- Liquidity risk
- The risk of being unable to meet cash commitments when they fall due.
Banking and Intermediation FAQ
Why can a solvent bank still fail during stress?
Solvency concerns whether asset value ultimately exceeds obligations, while liquidity concerns cash when payments fall due. A bank can own valuable long-term loans yet be unable to meet short-term withdrawals or refinancing needs if funding markets close.
Do off-balance-sheet items have no capital effect?
No. Guarantees, commitments and market-rate contracts can create contingent exposures. Their face amounts may first be converted into credit-equivalent amounts before risk weights are applied, so the absence of a current balance-sheet asset does not mean zero risk.
What is the difference between capital and liquidity?
Capital absorbs unexpected losses and protects creditors after current earnings are exhausted. Liquidity provides cash to meet daily and stressed outflows. Strong capital does not automatically provide readily available cash, and liquid assets do not by themselves remove credit losses.
Exam move
Begin with a two-column bank balance sheet. Place deposits, debt, hybrids and equity under sources of funds; place liquid assets, securities and loans under uses. Add a third margin for off-balance-sheet commitments so contingent exposures are not forgotten. For capital questions, build a table with exposure, risk weight and risk-weighted amount. Total the last column before applying any capital percentage.
Say explicitly when the calculation reflects the Basel II example shown in this course example rather than a live regulatory requirement. For scenario questions, separate credit loss, market loss, operational failure and liquidity pressure. If a bank funds long mortgages with unstable short borrowing, explain the maturity and refinancing mechanism rather than merely calling it risky.
Rehearse Australian regulatory roles by function: system stability and payments, prudential supervision, market integrity and consumer protection, and competition. End each answer by identifying which balance-sheet side or contingent claim produces the exposure.
