Working Capital Management
Working capital management is the art of balancing growth with liquidity. Commodity trading ties up enormous amounts of capital, and managing this effectively is essential for both profitability and survival.
The Cash Conversion Cycle
Understanding the Cycle
CASH CONVERSION CYCLE─────────────────────
Purchase Sale Collection │ │ │Day 0 ▼ │ │ PAY SUPPLIER │ │ │ │Day 30 ▼ │ DELIVER TO BUYER │ │Day 60 ▼ RECEIVE PAYMENT
CASH CONVERSION CYCLE = 60 DAYS
FORMULA:CCC = DIO + DSO - DPO
Where:DIO = Days Inventory Outstanding (30 days)DSO = Days Sales Outstanding (30 days)DPO = Days Payable Outstanding (0 days, if paid on purchase)
CCC = 30 + 30 - 0 = 60 daysImpact of CCC on Capital
WORKING CAPITAL REQUIREMENT───────────────────────────
DAILY PURCHASES: $10MCASH CONVERSION CYCLE: 60 days
WORKING CAPITAL NEEDED:$10M × 60 = $600M
IF CYCLE EXTENDS TO 75 DAYS:$10M × 75 = $750MAdditional: $150M
IF CYCLE SHORTENS TO 45 DAYS:$10M × 45 = $450MSavings: $150M
CONCLUSION:Every day of cycle = $10M more/less capital neededOptimizing Each Component
Days Inventory Outstanding (DIO)
INVENTORY OPTIMIZATION──────────────────────
CURRENT STATE:Average inventory: $300MAnnual cost of goods: $3.65BDIO: 300/(3,650/365) = 30 days
REDUCTION STRATEGIES:1. Just-in-time purchasing2. Better demand forecasting3. Faster vessel turns4. Reduce safety stock
TARGET:Reduce DIO by 5 daysNew inventory: $250MCapital released: $50M
CAUTION:Too lean = stockouts = lost salesBalance is keyDays Sales Outstanding (DSO)
RECEIVABLES OPTIMIZATION────────────────────────
CURRENT STATE:Accounts receivable: $300MAnnual sales: $3.65BDSO: 300/(3,650/365) = 30 days
REDUCTION STRATEGIES:1. L/C at sight (vs. deferred)2. Prompt invoicing3. Collection follow-up4. Early payment discounts5. Factoring/receivables finance
TARGET:Reduce DSO by 7 daysNew receivables: $230MCapital released: $70M
L/C IMPACT:Open account: 45 days DSOL/C at sight: 10 days DSODifference: 35 days capital freedDays Payable Outstanding (DPO)
PAYABLES OPTIMIZATION─────────────────────
CURRENT STATE:Accounts payable: $100MAnnual purchases: $3.65BDPO: 100/(3,650/365) = 10 days
EXTENSION STRATEGIES:1. Negotiate longer terms2. Early payment discount analysis3. Supply chain finance programs4. Strategic payment timing
TARGET:Extend DPO by 10 daysNew payables: $200MCapital benefit: $100M
EARLY PAYMENT DISCOUNT ANALYSIS:Terms: 2/10 net 30Discount: 2% for paying 20 days earlyAnnualized cost of not taking: 36.7%If borrowing cost < 36.7%: TAKE DISCOUNTCash Flow Forecasting

LIQUIDITY STRESS TEST─────────────────────
SCENARIO:Major buyer defaults on $50M payment
IMPACT:Week 1 collections: -$50MCash position: Goes negative
MITIGATION OPTIONS:1. Draw on RCF: $50M available2. Factor other receivables3. Delay supplier payment4. Accelerate other collections
POLICY:Maintain minimum cash buffer of 2 weeks' paymentsCurrent: $100M minimum cashCapital Allocation
By Business Line
CAPITAL ALLOCATION FRAMEWORK────────────────────────────
TOTAL CAPITAL: $2B
ALLOCATION BY DESK:Crude oil: $800M (40%)Products: $400M (20%)Metals: $400M (20%)Agriculture: $300M (15%)Other: $100M (5%)
RETURN REQUIREMENTS:Crude: 15% ROACE minimumProducts: 18% ROACE minimumMetals: 15% ROACE minimumAgriculture: 12% ROACE minimum
REALLOCATION:Quarterly reviewUnderperforming desks lose capitalOutperforming desks gain capitalReturn on Capital Employed
ROACE CALCULATION─────────────────
FORMULA:ROACE = EBIT / Average Capital Employed
EXAMPLE:EBIT: $300MCapital employed: $2BROACE: 15%
BY TRADE:Trade profit: $2MCapital tied: $100M for 60 daysAnnualized capital: $100M × (60/365) = $16.4MROACE: $2M × (365/60) / $100M = 12.2%
HURDLE RATE:Cost of capital: 8-10%Target ROACE: 15-25%Minimum acceptable: 10%Inventory Financing
Warehouse Financing
WAREHOUSE FINANCING STRUCTURE─────────────────────────────
SETUP:Commodity stored in approved warehouseBank takes security interest in inventoryAdvances against warehouse receipt
ECONOMICS:Inventory value: $100MAdvance rate: 80%Financing available: $80MInterest: SOFR + 150 bps
MONITORING:Warehouse issues daily stock reportsBank monitors value (mark-to-market)If value falls → margin call
BENEFIT:Frees capital vs owning outrightCost: ~2% per annumRepo Financing
COMMODITY REPO──────────────
STRUCTURE:Day 0: Sell commodity to bank @ $98MDay 0: Agree to repurchase @ $100M in 30 days
ECONOMICS:Implied interest: ($100-$98)/$98 × (365/30) = 24.8%(Expensive! Used only for short-term needs)
WHEN USED:Bridge financingUnexpected cash needBetter than selling at discountTreasury Operations

- CCC determines capital need — Shorter cycle = less capital
- Each component is optimizable — DIO, DSO, DPO
- Forecasting prevents surprises — Daily cash visibility
