If your Treasurer is not a Director or employee of the Association, then yes.
If your Treasurer
is a Director or employee of the Association then the Associations Crime Policy would cover (act as the bond).
Taking a quick look at the
DELAWARE UNIFORM COMMON INTEREST OWNERSHIP ACT I did not see any requirement.
According to
Delaware GENERAL CORPORATION LAW Subchapter IV. Directors and Officers, it's the corporations option to require fidelity bonds or not:
ยง 142: (c) The corporation may secure the fidelity of any or all of its officers or agents by bond or otherwise.
Therefore, it appears that the answer you seek about any requirement for a fidelity bond would be found within your governing documents. It may be in the CC&Rs or Articles of Incorporation but would most likely be found within your Bylaws.
Hope this helps,
