in the place I work I've noticed that for asset class Interest Rate Swaps, tenor bucketing takes place. Example as follow:
- IRS with maturity 2 month being bucketed into a "3 month tenor bucket"
Page 32878 of Federal Register speaks about it as well: https://books.google.com.ar/books?id=vJ9D8jDiXjoC&pg=PA32879&lpg=PA32879&dq=bucketing+tenors&source=bl&ots=nSlabnT3pJ&sig=ACfU3U2vqAsc9K9MebJlIf-i-pDK62AI6g&hl=es-419&sa=X&ved=2ahUKEwifvYHX28_nAhUhFLkGHXkxCMcQ6AEwAnoECAYQAQ#v=onepage&q=bucketing%20tenors&f=false
What is a logical reasoning to think this is acceptable?
