How Force Z survival redistributes Allied operations

What happens elsewhere when so many ships and commanders are concentrated in the Far East?

Madagascar may be delayed or unnecessary, later commanders are reassigned, and the wider result hinges on the major carrier battle.

Keeping Singapore and Force Z reduces the perceived need to invade Madagascar, freeing ships and changing who commands later operations. Syfret's move east could place Somerville over Operation Pedestal instead. Ships cannot be counted twice, so the Far Eastern concentration still forces tradeoffs in the Mediterranean and Indian Ocean. The largest consequences depend on the February-March carrier battle: an Allied victory stabilizes the Far East, while a defeat could lengthen the war substantially.
