Why are US treasury bonds priced in 32nds?
What is the historical reason for treasury bonds to be priced in 32nds?
I have tried using Google and this site to find the answer, but have not been able to find anything definite.
Three possibilities I found during my search that had no documentation what so ever backing them up:
Probably a carry-over from European influence in monetary system. Spain had "pieces of 8" coins... bonds might have been tic-priced on that concept... "1/8" of something being the smallest denomination. For bonds 1/8 was too large of a tic? So, 1/32 = 1/4 of 1/8. source
I believe it’s because the old ticker machines only had 32 symbols making each symbol (1/32) a tick. source
I suppose it remains from the LSD days when an eighth of a pound was 2s6d
Just something I always wondered about, but never actually got anyone to answer. So I hope someone on here knows why!

It used to be that stocks were traded in fractions too. It was only recently that they all were converted over into decimals.
I think you're basically right about being a holdover from Europe, especially Spain:
These early stockbrokers [who were trying to create the NYSE] looked to
Europe for a model to build their
system on and decided to base it on the system of Spain. This was
largely due to the fact that the U.S. dollar's value had been based on
the value of the Spanish real.
The real was the Spanish silver dollar and was divided into eight
parts. This evolved from the method of counting on the hands, similar
to the decimal system. The difference was that the decimal system used
the thumbs as part of the number while this other system used the
thumbs to denote the total of the four fingers. Therefore, a person
would count to four on one hand and then use the thumb to indicate a
total while they counted on the other hand. Two thumbs equaled eight.
The real could be broken into two, four or eight parts, giving birth
to the term pieces of eight.
