The HVAC Contractor's Inverted Curve
Maria, 55, owns a 38-employee HVAC contractor with $4.2 million annual revenue. She has a $600,000 variable-rate credit line priced at prime + 1.50%; prime is 8.50%. Receivables run 55 days, and her main supplier now quotes 90-day price locks. Over 18 months the Fed raised its policy rate by 300 basis points; the 2-year Treasury yields 5.10% and the 10-year 4.35%. Maria has $900,000 investable in a 60/40 portfolio and wants to move $400,000 into 10-year Treasuries because she has 'heard rates are high.' Her business has $180,000 of inventory financed on the credit line and a $250,000 equipment loan due in 14 months. She asks you whether the economy is slowing and what to do with the $400,000.
1. Identify the economic signals in the setup and explain how each might affect Maria's business cash flow and her personal portfolio.

The 2-year yield of 5.10% is above the 10-year yield of 4.35%, so the curve is inverted. That typically signals tight current policy and expectations of slower growth or later rate cuts, not necessarily an immediate recession. For Maria's business, the immediate issue is the floating-rate credit line: prime + 1.50% equals 10.00%, so a fully drawn $600,000 line costs about $60,000 of annual interest. The $180,000 inventory financed on that line carries roughly $18,000 of annual interest, and a further 100 bp increase would add about $6,000 to the line's cost. The 55-day receivables cycle ties up cash, so supplier price locks and inventory financing are both working-capital decisions. The $250,000 equipment loan due in 14 months creates refinancing risk if credit conditions tighten. For the portfolio, 10-year Treasuries at 4.35% lock in a nominal yield, but if inflation persists the real return may be low; if a slowdown arrives, yields could fall and bond prices could rise. The key is to separate business liquidity risk from household investment risk.
2. Evaluate the $400,000 recommendation against a Treasury ladder and against paying down the credit line. Use the numbers provided.

Paying down the credit line produces a known pre-tax savings of 10.00% on the amount repaid: $400,000 would save about $40,000 of annual interest. Even if the business deducts that interest, the after-tax cost is still likely above the 4.35% Treasury yield, so repayment is attractive on a risk-adjusted basis. But Maria should not drain all liquidity: she has a $250,000 equipment loan due in 14 months and 55-day receivables. A reasonable comparison is to keep a liquidity reserve, repay perhaps $200,000 of the line, and ladder the other $200,000 in 2- to 5-year Treasuries. The inverted curve makes the 2-year at 5.10% more attractive than the 10-year at 4.35%: $400,000 in the 10-year produces about $17,400 of annual interest, while the 2-year produces about $20,400. The ladder also matures around the equipment-loan date and reduces duration risk. Moving all $400,000 into 10-year Treasuries sacrifices both yield pickup and refinancing flexibility.
3. What three indicators should Maria monitor, and what would each imply for her decision?
Read the worked answer
First, monitor inflation data, especially CPI and PPI, plus the Fed's guidance. If inflation stays above target and the Fed keeps policy tight, short rates may remain high, favoring the ladder and line repayment over long Treasuries. Second, monitor bank lending standards and her own credit availability. If her bank tightens the line or the equipment loan refinancing looks difficult, she should prioritize liquidity and repay less of the line. Third, monitor supplier pricing and receivables. If price locks shorten or receivables stretch beyond 55 days, working-capital stress is rising and the $400,000 should stay shorter and more liquid. A secondary signal is the shape of the curve: if the 2-year falls below the 10-year, the market is pricing a more normal recovery and the case for extending maturities improves.
