Inverted Yield Curves and Recessions, Explained
The question
Explain the difference between a normal and an inverted yield curve, what each signals about the economy, and how the Fed influences the short end versus how the long end gets set. Why has an inverted curve historically preceded recessions?
General educational practice only. This is not an actual, confidential, leaked, or firm-provided interview question. Check important technical details against primary learning materials.
The answer
A normal yield curve slopes upward because longer maturities carry higher yields: the market expects growth and inflation, so investors demand a premium to lend for longer. An inverted curve is the opposite, short term rates rise above long term rates. That configuration has historically signaled a recession. The Fed controls the short end directly, it sets the policy rate.
When the Fed tightens aggressively to slow the economy, short rates jump. The long end, though, is set by the market's collective view on future growth and inflation. So an inversion tells you the market believes the Fed has tightened so much that a downturn is coming and will eventually force rate cuts.
That is why an inverted curve precedes recessions: it is a market price snapshot saying restrictive policy has pushed a slowdown into the base case.

- Elite: A distressed company has a reorg enterprise value of $950M against $600M secured, $500M senior unsecured, $250M subordinated, and $200M preferred, plus common.

- Elite: Build a WACC for a private target: comps' average unlevered beta 0.85, target D/E 0.50, tax 25%, pre-tax cost of debt 7%, risk-free 4%, ERP 5.5%. Then the Fed hikes 100bps (risk-free -> 5%, cost of debt -> 8%). Recompute WACC, and using a perpetuity with 3% growth, estimate the percentage change in DCF value from the rate shock. Show that the re-levered beta doesn't change and explain why.
- Elite: A buyer values a target with seller EBITDA of $100M (including $15M synergies and $10M SBC you disallow) at a 9x multiple. The target has a $150M NOL usable at $25M/yr for 6 years (25% tax, 8% discount, ignore Section 382). You move the $15M synergies to an earn-out paid at 9x, 45% probability, 2-year horizon, 10% discount. Compute the defensible EBITDA, upfront EV, PV of the NOL, PV of the expected earn-out, and total expected consideration to the seller, and state which single number you'd quote as 'the price.'
