One simple explanation is that US corporate management is generally the best in the world. American multinationals tend to outcompete European and Asian multinationals, even within their home markets. These findings are especially true when it comes to IT heavy industries, like finance.
What you'd expect is that any sufficiently globalized industry will ipso facto be dominated by American companies. Unless there's a compelling X factor that counterbalances the management differential. Like Japanese craftmanship in autos. Or the French culture of haute couture in luxury goods. But finance is sufficiently homogenous across cultures, that this probably isn't the case.
