The euro was seen bright on speculation it but equity markets slid worldwide when Germany’s move to ban some stock and bond trades unsettled investors. Bill McNamara, an analyst at Charles Stanley in Sweden said: "The markets never like governments interfering in what they regard as the efficient running of markets. "It just doesn’t settle the nerves in the way politicians seem to think it will. Investors should continue to expect high levels of volatility."The euro gained 1.72 percent to $1.239.
