Even at the once level headed Wall Street Journal, it seems now that any perceived wrong doing by banks is an opportunity for a headline article. This time around the topic is dividend arbitrage in securities lending, which has been flogged, abused and otherwise derided for years. Is it regulatory arbitrage? Of course it is. Is it legal and will be it commonplace until tax authorities harmonize their rules? Yes again. Unfortunately the WSJ has thrown mud into otherwise clearer waters.
