I am using interest rate data for all these treasury securities. Because bills, notes and bonds all are used for a certain maturity interval (https://en.wikipedia.org/wiki/United_States_Treasury_security#Directly_issued_by_the_United_States_government). I would like to know if one of the three words can be used as an umbrella term for them. Should I just use "treasuries" or should I go for the slightly longer "treasury securities"? Additionally, I would like to know if it should be capitalized in the middle of a sentence.

  • I'm voting to close this question as off-topic because it's about a domain-specific usage (that might be better addressed on SE Personal Finance & Money or Quantitative Finance). Commented Mar 6, 2019 at 13:13
  • I thought about quant.stackexchange.com, but that's rather technical and I am interested in the usage of these terms in an academic paper.

  • @FumbleFingers: isn't that what the terminology tag is for, domain-specific lingo?

  • @TRomano: First, the existence of any given tag needn't imply that all questions to which that tag might seem "applicable" must be definition be "On Topic". Second, the exact scope of that tag is open to interpretation. And third, I have VTCd many questions citing "domain-specific usage" over the years - which still seems a perfectly reasonable position to me. Commented Mar 6, 2019 at 14:14
