It depends. There are multiple meanings of the word treasury and the spelling of the plural varies by meaning. If you mean a place where money is kept, the plural is treasuries. But treasury can also mean a United States Treasury Bond. In this case the proper spelling of the plural form is Treasurys. Note the capitalization.
The plural of treasury is treasuries, and not treasurys. You may have seen treasury's, and didn't notice the apostrophe. Apostrophe s ['s] usually indicates possessive. In this case, it would mean "something held or owned by a treasury". "The nation possesses a lot of gold, but its treasury's art holdings are even more valuable." [Just to be sure it's clear-- in this sentence there is one treasury. It has some art holdings.]Actually, the Wall Street Journal has been spelling it treasurys when they refer to multiple bonds for years. I wrote them about it but they continue with the incorrect spelling.
