While the flight may be economy (generic Y) it may not be Y fare booking class. Y fare booking class can be very expensive, but price can vary.
Corporate fares can have other restrictions.

For redemption of upgrades from Economy to Premium Economy Class or Business Class, only tickets purchased in Economy Standard (M, H or W booking classes) and Economy Flexi (Y, B or E booking classes ) on flights operated by Singapore Airlines or SilkAir are eligible.
Upgrades from Economy Class to Business Class for flights with a Premium Economy Class cabin are available with effect from 3 January 2019.
Codeshare flights are not eligible for upgrades.
Premium Economy Lite and Business Lite fares will not be eligible for redemption upgrades. For most fare types across all cabin classes, the number of KrisFlyer miles required for redemption upgrades remains the same.
