Bond Market Strategy for Yield Curve Steepening

This question is about structuring a fixed income trade to express a specific view on the shape of the yield curve, namely a steepening between short and long maturities. The candidate is asked to think like a rates trader or strategist: given a macro view on how short-term and long-term yields might move relative to each other, how do you translate that into a position in bonds or bond-like instruments that profits if the view is correct and limits exposure to unrelated rate moves. This style of scenario is common in interviews for rates trading, fixed income structuring, and macro hedge fund roles where relative value and curve positioning matter more than outright duration bets.

To answer it well, the candidate must draw on yield curve decomposition, duration and convexity, and the idea of neutralizing parallel shifts to isolate slope exposure. Mathematically, the interviewer expects the use of Taylor expansion of bond prices in yields, explaining why first- and second-order terms behave differently across maturities. The economic intuition behind convexity, and why it is desirable or not in different steepening paths, is important. The interviewer is watching for coherent linkage between macro view, portfolio construction, and risk sensitivities, not just naming a textbook trade.

What it tests

Yield curve trades fundamentally rely on decomposing interest rate risk into orthogonal components: level (parallel shifts), slope (steepening/flattening), and curvature. The key is that a bond portfolio's price sensitivity to yield movements can be expressed as a weighted sum of its exposures to these components, with duration capturing first-order (linear) sensitivity and convexity capturing second-order (nonlinear) effects. By constructing a portfolio that is duration-neutral (zero net exposure to parallel shifts), you isolate exposure to changes in the slope (i.e., the difference between short- and long-term rates). This works because the price change of a bond to a yield change is approximately linear in duration and quadratic in convexity, so by matching durations but mismatching maturities, you create a portfolio that is only sensitive to non-parallel movements. The pattern holds because the mathematics of bond pricing (via Taylor expansion) separates these effects cleanly, allowing targeted bets on specific yield curve movements.
