The guerrilla currency issued across Negros Island during the Japanese occupation exists in a category apart from the better-documented Philippine Commonwealth emergency notes. The Free Negros Military Currency Committee operated under IV Philippine Corps authority, meaning these notes carried official U.S. Army backing — they were not informal scrip but instruments of a functioning resistance economy, used to pay troops, purchase supplies, and sustain civil administration in territory the Japanese nominally controlled but never fully pacified.

Negros was unusual in that its guerrilla organization remained unusually cohesive through 1943–44, which gave its currency a credibility that most provincial emergency issues lacked. Forgery by Japanese-sponsored counterfeiters was a documented problem across the Philippine guerrilla currency series broadly.
