The abacá fiber content is not decorative specification — abacá (Musa textilis) has been cultivated in the Philippines for centuries and once dominated global cordage markets, making its inclusion in the banknote substrate a deliberate material choice with deep economic roots in the country's agricultural history. The BSP has incorporated it into the paper blend since at least the New Generation Currency series launched in 2010, partly to reduce dependence on fully imported cotton substrate and partly to support domestic abacá production.

The Security Plant Complex has printed Philippine currency in-house since 1978, one of relatively few central banks in Southeast Asia operating its own full-production facility rather than contracting to De La Rue, Giesecke+Devrient, or similar private printers.
