# Introducing SONAR’s ‘Panama spread’ - FreightWaves

> FreightWaves launched SONAR's 'Panama spread' index, which subtracts the China-to-US West Coast container rate from the China-to-US East Coast rate to track the relative attractiveness of each port range. The expanded Panama Canal has shifted container volumes toward East Coast ports, which recently overtook West Coast volumes.

## Why it matters

The index tracks container freight economics rather than grain bulk flows, so its direct effect on feed grain and meal prices is minimal.
