AI for Interest Rate Risk: Hedging Strategies and Duration Analysis with Claude (2026)

Interest Rate Risk and AI

Rising rates from 2022-2023 caught many corporate treasurers with unhedged floating-rate debt, costing millions in additional interest expense. Conversely, falling rates in 2024-2025 squeezed returns on cash portfolios. Claude with ClaudeFinLab helps treasury teams model interest rate exposure, design hedging strategies, compute DV01 and duration, and document hedge accounting under ASC 815.

Exposure Analysis

• "Compute the interest rate exposure for our debt portfolio: Term Loan B $280M, SOFR+275bps, current all-in 8.0% (floating). Senior Notes $150M, 5.25% fixed, maturing 2028. Revolver $80M drawn, SOFR+200bps (floating). Total floating-rate exposure: $360M. For a +100bps rate move: additional annual interest expense = $360M × 1% = $3.6M. After-tax impact at 25% tax rate: $2.7M. EPS impact (60M diluted shares): -$0.045/share. Is this material? What percentage of EBITDA ($85M) does the $3.6M pre-tax impact represent?"
• "Analyze the floating-to-fixed mix: current mix 71% floating / 29% fixed. For a technology company (high earnings variability already), best practice mix is typically 50-70% fixed to reduce earnings volatility. Our current mix creates significant P&L sensitivity to rate moves. Board has approved hedging up to 50% of floating-rate debt with interest rate swaps. Compute the target hedge notional to achieve 50% fixed / 50% floating mix."

Interest Rate Swap Design

• "Design a receive-fixed / pay-SOFR interest rate swap to hedge $180M of the TLB: 3-year term (matching average expected life of TLB), fixed rate 4.25% (current mid-market for 3-year USD swap), quarterly settlement in arrears, SOFR compounded in arrears. Net effect: our TLB pays SOFR+275bps. Swap receives 4.25% / pays SOFR. Net all-in rate: 4.25% + 275bps = 7.00% (fixed equivalent). Current unhedged rate: 8.0% (SOFR 5.25% + 275bps). The swap reduces current cost by 100bps but limits benefit from future rate cuts. Compute the break-even SOFR rate at which the swap becomes value-neutral."
• "Evaluate cap vs swap for rate hedging: Interest rate cap on $180M at 5.0% SOFR strike, 3-year term, upfront premium $2.4M (quoted). Vs receive-fixed swap at 4.25%: no premium, but gives up benefit from rate cuts. At current SOFR 5.25%, cap is in-the-money (protection from further rises). If SOFR falls to 3%, cap expires worthless (lost $2.4M premium) but swap gains value (receiving 4.25% fixed > paying 3% floating). Which instrument is better given the rate uncertainty? Show the total cost (including premium) at 3%, 5%, 7% SOFR scenarios."

Hedge Accounting Under ASC 815

• "Set up fair value hedge accounting for the interest rate swap: we are designating the receive-fixed / pay-SOFR swap as a fair value hedge of fixed-rate senior notes ($150M, 5.25% coupon, maturing 2028). Under ASC 815 fair value hedge: (1) the hedged item (fixed-rate notes) is remeasured to fair value through income; (2) the derivative (swap) is also remeasured to fair value through income; (3) net income effect = hedge ineffectiveness only. In a +100bps environment: swap fair value gain $4.2M, note fair value loss $4.1M, net P&L impact $0.1M. Draft the hedge documentation required under ASC 815-20-25."
• "Assess hedge effectiveness under the shortcut method: our receive-fixed/pay-SOFR swap qualifies for the shortcut method if: (1) notional matches the principal of the hedged item exactly ($150M = $150M); (2) fair value of swap at inception = 0 (market terms); (3) fixed rate and coupon rate are the same (5.25% = 5.25% — yes, we can structure this way); (4) repricing dates match; (5) no floor or cap on swap. Under shortcut, assume perfect effectiveness — no quarterly ineffectiveness testing required. What are the journal entries at inception and at first remeasurement?"

SOFR Transition and Reference Rate Risk

• "Analyze SOFR transition risk in our debt portfolio: all floating-rate debt now references SOFR (LIBOR transition complete). Our TLB credit agreement uses term SOFR + CSA (credit spread adjustment) 11.448bps (the standard ARRC adjustment). Current all-in: term SOFR 5.25% + CSA 0.114% + spread 2.75% = 8.114%. Compare to what the rate would have been under USD LIBOR (using historical correlation): LIBOR was typically SOFR + ~10-15bps term premium. Is the SOFR transition net positive or negative vs what LIBOR would have been? Estimate the annual dollar impact."

Where to Start

Start with the exposure analysis — compute total floating-rate debt and the annual interest expense impact per 100bps move. Present this in dollar terms and as % of EBITDA. Then ask Claude to design the swap that achieves your target fixed/floating mix. For hedge accounting documentation under ASC 815, describe the hedge relationship and Claude will structure the documentation requirements — hedge objectives, risk management objective, and effectiveness assessment methodology.
