Last year it was the BOE gov Mark Carney who stole the show at this annual City event by talking up interest rate hikes and sending the pound soaring
For a trip down memory lane you can view the whole speech here and read here the immediate post by our intrepid man Down Under as the news hit the wires.
Carney was later to say that it was designed to bring forward the market's expectations which he felt were lagging behind the curve
So much for that prediction and Carney will have learnt a valuable lesson about the BOE ways not least of which his admission that he had spoken at Mansion House without prior consultation with his esteemed colleagues.
Is he likely to make such waves this evening? Unlikely, but there was definitely a more political tone on fiscal reform in his post-election inflation report and, not being a wall flower, he may well seize the opportunity for another dig at the man sitting next to him.
That man being fin min George Osborne who tonight will lay out his plans to introduce legislation to bind his and future governments to a Budget surplus when the economy is growing, limiting governments to a balanced budget in "normal" times. These changes to fiscal policy were first proposed by him in January so will not exactly be revelatory but, being a real political animal, he will be keen to stamp his authority over the occasion and drop some decent sound bites
The Beeb carries more on his expected speech here
So, Osborne to take centre-stage in theory but don't rule rule out Mr C chipping in with a headline or two of his own
In any case Carney's speech gets posted here at 16.00 GMT ahead of the event and you can be sure that ForexLive will be all over it
Listen Mark, It's my turn for the spotlight. Understood?
