The European Central Bank is now involved in designing the proposed European Financial Transaction Tax, which is concerning for supporters of the tax. The ECB is expected to side with the powerful financial lobby that is strongly opposed to the tax. Private meetings between ECB officials and financial industry representatives have revealed intensive lobbying against the tax. There is a risk that the ECB's involvement will provide more opportunities for the financial lobby to water down the tax through exemptions and other changes, undermining its ability to reduce risky high-frequency trading and generate substantial revenue.
