Dragon is the most wanted man in the world, and Luffy is his son. We can safely say that Dragon has an extremely high bounty, and the government will say they increased Luffy's bounty because of this. I mean, the higher his bounty, the more pirates/bounty hunters will want to hunt Luffy down, and turn him in. This in turn will lure in Dragon, which is an intelligent method to get Dragon to surrender to the World Government.

Also, the government now see Luffy as a major threat... He managed to infiltrate Imply Down and also escape, and in the meanwhile, he went to battle at the World Government's Headquarters... They'll probably cover up the Imply Down situation, as they wouldn't want to make themselves look weak, but I doubt they can cover Luffy's involvement in the battle, as everyone watching in the world was told he was Dragon's son.

He nearly managed to rescue Ace - he was acknowledged by Whitebeard, after he released his Haki, which only one in a few million can possess... There are many reasons as to why his bounty will increase threefold.

It will increase three times its current bounty... I only say this because his first bounty was 30,000,000 then 100,000,000, then 300,000,000... Next will be 1,000,000,000 at the max. Zoro followed a similar pattern - his increased by two times (60,000,000 to 120,000,000).

An admiral was unable to capture Luffy, and he escaped the battle. He punched a royal as well, so they will want to put the biggest bounty possible to have revenge on Luffy... The reasons are all there. Now it's just Oda's turn to act.

The bounty: 1,000,000,000.
