BFF2401 Chap.5 Liability and Funding Management

Liability and Funding Management

Define funding mix

The course material gives this chapter a concrete anchor: Week 5 is officially Liability Management and precedes the 35% Week 6 test. That funding mix anchor controls how rollover risk is explained and how funding concentration is tested in changed practice.

Liability and Funding Management is a quantitative decision problem built from funding mix, rollover risk and funding concentration.

The aim is to compare funding sources by cost, maturity, repricing, collateral and concentration; a numerical result earns meaning only when the variables, units, assumptions and comparison are all explicit.

Begin with funding mix: state what quantity it represents, the scale on which it is measured and the condition under which it changes.

Then map every symbol in the Liability and Funding Management formula checkpoint to funding mix before calculation begins.

Next connect rollover risk to the calculation. Show the rollover risk transformation line by line, preserve units and signs, and make any denominator or baseline visible.

A rollover risk calculator output is not a method; the reader must be able to reconstruct why that operation answers the question.

Trace rollover risk

Use funding concentration to interpret or stress-test the result.

Ask whether the funding concentration magnitude is plausible, whether a boundary case behaves as expected and which conclusion would reverse if an assumption changed. This is where computation becomes analysis rather than arithmetic.

When the task is to compare funding sources by cost, maturity, repricing, collateral and concentration, separate inputs supplied by the problem from quantities you derive.

Then report the funding concentration result in the language of the course and attach the relevant uncertainty, limitation or decision consequence.

Build a representation check before solving. Put funding mix, rollover risk and funding concentration into a small symbol-and-units table, mark which values are observed and which are calculated, and predict the direction of the result before doing arithmetic.

A sign, scale or unit mismatch in funding mix then becomes visible at setup instead of being hidden inside a polished final number.

Run one sensitivity test after the baseline answer. Change the input most closely connected to rollover risk, hold the remaining assumptions fixed and recompute only the affected steps. Explain whether the movement in funding concentration matches the mechanism.

This rollover risk sensitivity shows which assumption controls the conclusion and prevents a single scenario from being presented as universal.

Test with funding concentration

Use a three-column funding mix error log for bff2401: translation error, calculation error and interpretation error.

Record the exact line where the rollover risk solution first diverged, rewrite that line, and check it with a limiting case or an independent calculation.

Correcting the first failed rollover risk move is more useful than copying the complete solution again.

A complete response should make the task visible before the detail: identify what must be decided, define the relevant terms, connect the evidence to rollover risk, and use funding concentration to test the result.

The final sentence about funding concentration should answer the question actually asked rather than merely repeat the topic.

The controlling limit is specific: The cheapest observed funding can create hidden liquidity, option and reputational exposure.

Keep that funding concentration limit beside the worked example, because it separates a careful bff2401 answer from one that sounds confident but claims more than the task or evidence supports.

For revision, retrieve funding mix, rollover risk and funding concentration without notes, explain their relationship aloud, then complete a changed version of the application: compare funding sources by cost, maturity, repricing, collateral and concentration.

Record the first failed rollover risk reasoning move and repair it before attempting another case.

Key terms

funding mix

Combination of deposits, wholesale borrowing and other liabilities financing bank assets. This chapter uses the concept when students compare funding sources by cost, maturity, repricing, collateral and concentration. Use this definition when the task is to compare funding sources by cost, maturity, repricing, collateral and concentration.

rollover risk

Risk that maturing funding cannot be renewed on acceptable terms. It helps explain the reasoning required to compare funding sources by cost, maturity, repricing, collateral and concentration. Use this definition when the task is to compare funding sources by cost, maturity, repricing, collateral and concentration.

funding concentration

Dependence on a limited set of providers, instruments, markets or maturities. Its limit matters because the cheapest observed funding can create hidden liquidity, option and reputational exposure. Use this definition when the task is to compare funding sources by cost, maturity, repricing, collateral and concentration.
