Peter Martin reminds us that the Aussies stopped Centrebet contracts on the Aussie Reserve Bank decision. But, Sportsbet.com.au apparently is still offering contracts: $1.20 for $1 on no change and $3 for a rate hike.
iPredict's contracts are at $0.67 for no change ($1 gets you $1.49); $0.31 for a 25 bp increase ($1 gets you $3.22); $0.02 for a 50 bp increase ($1 gets you $50). iPredict takes its 2% commission on profits at withdrawal.
Too bad the Australians aren't allowed to trade on iPredict; the prices are better.
