In practice, how are swap spread positions actually sized and constructed between the two legs? I would suppose the two legs are simply matched in notional terms.

However, in practice, do traders ever attempt to run some sort of swap spread position with a duration bias? For example, having a swap spread widener on with slightly more dv01 on the pay fixed swap?

Yes, generally you want it dv01 hedged not notional hedged to capture the spread changes in basis points.

  • $\begingroup$ Thanks Edward. Do you have any insight on whether in practice, trades sometimes run a duration bias by underhedging or over hedging one of the legs? $\endgroup$ Jan 8, 2021 at 11:19
  • $\begingroup$ Maybe, people use all types of different hedging strategies including principal component analysis, regressions, dv01. Many swap and curve trades are directional so you might have a duration bias, but probably not for the purposes of having an explicit duration bias. $\endgroup$ Jan 8, 2021 at 14:44
