Business news in brief: Swiss banks SWITZERLAND'S aim of preserving banking secrecy has been cast in doubt after the finance minister suggested all options are open, reopening the debate over a pillar of the country's economy. The Swiss government had pledged its commitment to tax deals allowing European Union citizens to pay tax on secret Swiss accounts without revealing their identity. But Swiss finance minister Eveline Widmer-Schlumpf said: "We will enter a dialogue with the EU Commission on possible information and what we are prepared to discuss and what we would want for it in return." Banks urged to use in-house managers Banks will need to step up their use of in-house asset management operations to fund loans for their customers, according to a new report. Lenders have already begun tapping asset managers for cash to fund deals but the practice is expected to spread from multi-national corporate work into other parts of the banks" operations. Steven Lewis, an analyst at Ernst & Young, who compiled the report, said: "Banks will also need to respond to innovation from newer players who offer more targeted and fewer "one-size-fits-all" services."
