AI for Bank Lending: Claude Tools for Commercial Loan Origination and Credit Analysis

Bank Lending and AI

Commercial bank lending — from small business loans to middle market credit facilities to large corporate revolvers — requires rigorous credit analysis: understanding the borrower's cash flow capacity, collateral adequacy, management quality, and industry risk. Claude with ClaudeFinLab accelerates the credit memo writing, DSCR modeling, covenant structuring, and risk classification that are central to commercial lending workflows.

Credit Memo Preparation

• "Draft a commercial credit memo for a $2.5M term loan to a regional HVAC contractor: Revenue $8.4M, EBITDA $1.12M, net income $680K. Collateral: commercial real estate (shop/warehouse) appraised at $3.2M with $1.8M existing mortgage → LTV on new loan 45% combined. Personal guarantee from owner (net worth $2.8M, liquid assets $480K). Industry: essential services, relatively recession-resistant. Draft sections: (1) loan purpose, (2) borrower profile, (3) financial analysis, (4) cash flow analysis, (5) collateral, (6) guarantor, (7) risk assessment, (8) recommendation."
• "Credit memo global cash flow: the borrower is an S-Corp where business income flows to personal return. Business EBITDA $1.12M, less: owner's salary drawn from business $180K (already in EBITDA), taxes estimated at 32% on net income $680K = $218K. Debt service on proposed loan: $2.5M term, 7 years, 6.75% = $456K/year. Personal obligations: mortgage $48K/year, car $18K/year, other $24K/year. Global cash flow analysis: $680K business cash − $218K taxes − $456K business debt − $90K personal debt = remaining $84K. Is this adequate global DSC?"

DSCR Analysis

• "DSCR calculation for commercial real estate loan: NOI from property $284K. Proposed loan $2.8M, 25-year amortization, 7.25% rate → annual debt service $246K. DSCR = NOI / DS = $284K / $246K = 1.15x. Bank minimum DSCR policy: 1.25x. This loan fails the minimum DSCR test. Options: (1) reduce loan to $2.24M (what DSCR = 1.25x requires: $284K / 1.25 = $227K DS max → loan at 1.25x constraint); (2) shorten amortization to 20 years on $2.8M ($258K DS → DSCR 1.10 — worse); (3) increase NOI by requiring rent increases."
• "DSCR stress test: base case NOI $284K, DSCR 1.15x. Stress scenarios: (1) 10% vacancy increase (from 5% to 15%): NOI falls $44K → $240K → DSCR 0.98x (below 1.0 — cash flow insufficient). (2) 50bps rate increase at reset (5-year balloon, then resets): DS increases $12K → $258K → DSCR 1.10x (thin). (3) Major tenant non-renewal (35% of rental income): NOI falls $99K → $185K → DSCR 0.75x (severe). Key risk: tenant concentration."

Collateral Assessment

• "Collateral analysis for an operating business loan: proposed collateral — accounts receivable $1.8M, inventory $0.84M, equipment (appraised) $1.2M. Advance rates per bank policy: AR 80% (eligible) = $1.44M, inventory 50% = $420K, equipment 70% of appraised = $840K. Total collateral availability: $2.7M. Loan amount $2.5M. Overcollateralization: $2.7M / $2.5M = 108%. Borrowing base: if AR fluctuates seasonally and drops to $1.2M in Q1, availability drops to $2.4M — borrower may need to paydown. Design the borrowing base certificate."
• "Appraisal review: commercial property appraised at $3.2M using sales comparison approach. Review the appraisal: (1) comparables — are the 4 comps within 10 miles and sold within 18 months? (2) adjustments — is the net adjustment per comp below 15%? (3) income approach: cap rate used 6.8% vs market 6.2-7.2% (reasonable). (4) Cost approach: replacement cost $2.8M − depreciation. Reconciliation: sales comparison $3.2M, income $2.95M, cost $2.6M. Weighted average $3.07M. At 75% LTV: max loan $2.3M — the $2.5M loan is slightly over this constraint."

Covenant Structuring for Commercial Loans

• "Covenant package for a $5M revolving credit facility to a manufacturing company: recommend: (1) Fixed Charge Coverage Ratio ≥ 1.20x (EBITDA − capex − taxes) / (interest + principal), tested quarterly; (2) Maximum total leverage ≤ 3.5x Debt/EBITDA, tested annually; (3) Minimum liquidity (cash + revolver availability) ≥ $500K at all times; (4) Capital expenditure limitation ≤ $800K/year without prior bank approval. Rationale: FCCR provides the tightest early warning; leverage prevents over-borrowing; liquidity prevents surprise; capex limit protects cash flow."
• "Covenant compliance projection: FCCR covenant 1.20x. Company's projected FCCR: Q1 1.18x (breach — just below 1.20), Q2 1.24x, Q3 1.28x, Q4 1.32x. The Q1 breach is projected. Options: (1) waiver request (bank will charge fee and may require equity injection); (2) increase revolving credit limit to improve liquidity metric before test date; (3) restructure principal payments to push annual amortization to after Q1 (seasonal business). Recommend approach and waiver memo language."

Regulatory Credit Classification

• "OCC credit classification analysis (for bank examiners and credit review officers): Borrower X, $2.8M term loan, 42 days past due, one covenant breach (DSCR 1.08x vs 1.25x minimum). OCC classification framework: (1) Pass — no significant weaknesses; (2) Special Mention (OAEM) — potential weaknesses that deserve close attention; (3) Substandard — inadequately protected, well-defined weakness, possible loss; (4) Doubtful — collection in full highly questionable; (5) Loss — uncollectible. Based on: 42 days past due + covenant breach + DSCR only 1.08x → recommend Substandard classification. Provision: 15% of outstanding balance."

Small Business Lending (SBA Loans)

• "SBA 7(a) loan analysis: small business, 3 years in operation, revenue $1.2M, net profit $96K, owner's salary $80K. SBA eligibility: for-profit US business, within SBA size standards (manufacturing: 500 employees), business unable to obtain conventional financing on reasonable terms. SBA loan amount: $750K at prime+2.75% (SBA max). DSCR including owner's salary: ($96K + $80K) / proposed DS ($750K, 10yr, 8.25% = $111K) = $176K / $111K = 1.58x. SBA DSCR requirement ≥ 1.25x. Eligible."
