Equity Research interview preparation
Sell side and buy side. Every question is either traced to a named firm from a public candidate report, or tagged at desk level when we could not trace it. Answers lead with the point, then the mechanism, then the limitation.

012What is the yield curve, what does it mean when it inverts, and why do people treat that as a recession indicator?State StreetEquity Research · Boston · 2020
Say this
It plots government bond yields against maturity. Normally it slopes upward because investors demand more for lending longer. An inversion means short rates exceed long rates, which says the market expects the central bank to be cutting in future.
Then walk it
- The normal upward slope comes from term premium and from expected growth and inflation.
- An inversion means the market expects policy rates to be lower in two years than today. Rates get cut when growth is weak, so an inversion is a forecast of weakness rather than a cause of it.
- The track record is why people watch it: in the US, a sustained 2s10s or 3m10y inversion has preceded every recession since the 1960s, usually by 12 to 18 months.
- There is also a causal channel, not just a signal. Banks borrow short and lend long, so an inverted curve compresses net interest margin and reduces the incentive to extend credit. Tighter credit slows the economy.
- The honest caveats: it has produced false positives, the lead time is long and variable, and quantitative easing distorted the term premium enough that the signal may be weaker than history suggests. An analyst who names that is more credible than one who treats it as a law.
Where candidates lose it
Describing the shape without explaining the mechanism, or treating the indicator as infallible. Both the expectations channel and the bank lending channel should appear, along with at least one reason to doubt it.
Expect next
- Which part of the curve do you watch?
- How does an inversion affect bank earnings?
- What is happening to the curve right now?
