Long-Term Value at Risk · Working Paper 09
The same float is worth 1.5 to 2.5 per cent to an investment-grade buyer and costs a capital-constrained Asian supplier 12 to 18 per cent. When a large firm finances its working capital by paying its supplier tier late, the chain destroys five to eight times what it moves. This paper prices the alternative.
The same float is worth 1.5 to 2.5 per cent to an investment-grade buyer and costs a capital-constrained Asian supplier 12 to 18 per cent. When a large firm finances its working capital by paying its supplier tier late, the gain is real but local, while the chain destroys five to eight times what it moves.
Three engines make supplier enablement privately rational for the buyer, stacking in order. First, credit arbitrage: buyer-led supply chain finance lends the buyer's credit rating so the supplier is paid at investment-grade rates while the buyer's float is undisturbed. Second, a resilience gain: switching and disruption costs avoided cover the whole programme. Third, a transition co-benefit: a readier supplier tier lowers the buyer's own transition value-at-risk.
The case holds on engines one and two alone. Engine three means the buyer does not have to win the Scope 3 argument to improve Scope 3 outcomes. Capacity is not the obstacle: allocatable funding covers the incremental transition requirement nearly four times over for large entities.
Value-chain buyers, CFOs, and chief procurement officers
You sit at the top of a supply chain. You treat payment terms as a Treasury lever. The paper prices what that gain actually costs the whole firm. Treasury books the working-capital efficiency; the loss lands on Procurement's continuity and the firm's own resilience. Widen the boundary to the whole entity and the extracted float generates close to zero net value, while the chain destroys five to eight times what it moves. The paper is the arithmetic your CFO and CPO can build a decision on.
Development capital and trade-finance institutions
You deploy development capital into MSME resilience or Asian trade finance. The paper argues supply chain finance is the region's most under-used piece of infrastructure. Weighting programme access or pricing by readiness converts the existing rail into transition finance at near-zero fiscal cost. The buyer's balance sheet, not the state's, carries it. Enable rather than mandate: the natural experiments show mandated terms cut both ways.
Banks and corporate lenders structuring supply chain finance
You structure supply chain finance programmes or corporate credit facilities. The paper gives you the readiness-weighted variant that clears the reputational shadow of Greensill. It is buyer-backed, disclosed, funding supplier resilience rather than disguising buyer leverage, and leaving the buyer's float unchanged. It is distinguished from the misuse on exactly the dimensions FASB and IASB standards target. The trade-finance gap of roughly 47 per cent of unmet MSME credit demand in the region is the market this instrument scales into.
Late payment is a net loss because the same float is priced at two different costs of capital. The buyer captures the float at its own short-term funding rate, roughly 1.5 to 2.5 per cent for a top-tier SGD borrower and near 5 per cent for USD investment grade. The supplier bears the identical delay at its own cost of capital: SME weighted average cost of capital of 9 to 16 per cent, and distressed marginal financing of 12 to 18 per cent. The spread between the two rates is pure loss, value the chain destroys to move cash uphill. Extraction is worse than a transfer: closing the gap picks up money the chain is currently burning.
The three engines make supplier enablement privately rational for the buyer, stacking in order. First, credit arbitrage: buyer-led supply chain finance lends the buyer's credit rating so the supplier is paid at investment-grade rates near 5 to 6 per cent, while the buyer's payment run and float are undisturbed. This is close to costless. Second, a resilience gain: liquid suppliers fail less, and switching and disruption costs avoided cover the whole programme. This is self-funding on calibrated ranges. Third, a transition co-benefit: a readier supplier tier lowers the buyer's own transition value-at-risk, because that is where its Scope 3 sits. The case holds on engines one and two alone.
No. Across the series' listed-entity coverage, allocatable capacity covers the incremental transition requirement roughly 3.9 times over. It stays above two times even when the requirement is doubled. Entity by entity, 88 to 98 per cent can self-fund across scenarios. Any shortfall concentrates where coverage runs closest to one, in utilities and energy. The binding constraint is not the balance sheet. It is the decision to ring-fence funds. The accounting boundary at which the balance sheet is read is what constrains enablement, not capital.
A mid-cap buyer example: US$50M annual spend across 40 critical SME suppliers on Net-90 terms. At the invoice level, a US$100,000 invoice accelerated 80 days through supply chain finance costs the supplier roughly US$1,205 (about 1.2 per cent of face value) against US$4,000 to US$6,000 through independent factoring. The buyer's payment day, and its float, do not move. Over the year, at a 12 per cent supplier failure rate, prompt liquidity cuts failures by a quarter. This avoids 1.2 failures a year at roughly US$275,000 each, or US$330,000. Against a programme cost of US$100,000, the buyer is US$230,000 ahead on resilience alone before a tonne of Scope 3 is counted.
The instrument recommended here is distinguished from that misuse on exactly the dimensions FASB and IASB standards target. It is buyer-backed and disclosed. It funds supplier resilience rather than disguising buyer leverage. It leaves the buyer's float and reported position unchanged. Greensill used reverse factoring to obscure leverage and supplier dependence. The regulatory response was disclosure, not prohibition: FASB required supplier-finance programme disclosures in 2022, and IASB followed with amendments to IAS 7 and IFRS 7 in 2023. The case rests on transparency being present, which is what separates enablement from the practice the standards were written to expose.
The natural experiments cut both ways. France's statutory 30-day cap cut supplier default probability by roughly a quarter, persistently and without offsetting profit loss (Barrot, 2016). China's 2018 SME Promotion Law curbed listed-firm appropriation of supplier credit. But Chile's cap cut the likelihood of trade itself by 11 per cent, as buyers dropped regulated counterparties and internalised procurement (Breza and Liberman, 2017). Mandated terms are context-dependent and can trigger avoidance. Enablement sidesteps that variance by being privately rational for the buyer rather than imposed on it. It is the lower-risk, fiscally cheaper route regardless.
WP-09 closes the series' diagnostic arc where a transaction can begin. It equips the population WP-08 measured: below the disclosure line, supplier motivation alone will not fund the base of the chain, so the buyer's credit rating substitutes for what the small firm cannot self-source. It is the working-capital form of WP-07's booking-point-versus-resting-point structure, showing what happens when Treasury's gain and Procurement's loss are read within a single balance sheet. And it is the operational funding case for the reversal WP-06 argued for architecturally: enablement, not exhortation, funded by the arithmetic the buyer can already see.
