In EF, BA's new fares are:

DONE4 MZN357,060 (up from MZN162,300)
DONE5 MZN407,000 (up from MZN185,000)
DONE6 MZN495,000 (up from MZN225,000)

AONE4 MZN581,900 (up from MZN264,500)
AONE5 MZN669,900 (up from MZN304,500)
AONE6 MZN803,000 (up from MZN365,000)

Note: the "up from" base fares are what is showing in EF right now for AA fares ex-MPM
The new fares are more than double the old fares

However, given the way the MZN is falling against 'hard' currencies, maybe we all just have to wait little while until these new fares come back to what the previous fares were in USD terms
But, then again we know of currencies where Oneworld abandoned use of the local currency and started quoting fares in USD only.
