Witholding Tax: ECB and the ghosts of Regulation Q

Thirty years ago, US withholding-tax regulations kick-started the Eurodollar market which Euromoney was founded to report on. And today, withholding-tax regulation is again a hot topic in the international bond markets. Although the European Central Bank (ECB) has refused to comment publicly on the recent furore over savings tax harmonization, saying it is purely a matter for the European Commission, it is understood that senior ECB figures are in favour of harmonizing withholding taxes throughout Europe. This would involve the introduction of a withholding tax to be enforced in London. The ECB's motivation to support such regulation could be said to be the same as that behind its determination to restrict the access of UK institutions to the European cross-border payment system, Target. The bank is believed to be extremely uncomfortable with the idea of having the principal money market for its new currency located outside the eurozone, fearing that this would compromise the ability of the ECB to conduct monetary policy.
