LONDON (Reuters) - Arcane measures designed to make banks safer are pushing trading activity into areas where the banking regulator's writ doesn't run, making conventional markets more risky as volumes dwindle.
Regulators determined to avoid a repeat of the financial crisis that floored investment banks in 2008 and beyond introduced a rule at the beginning of last year that makes banks hold enough capital to cover the worst 12 months in the history of their trading portfolio, on top of a capital provision to cover recent asset volatility.

"The regulators, as well as the banks, don't necessarily have a full grasp of the impact of these types of things yet, and won't have for some time," said one senior executive at a major investment bank, who said there had been "pretty big" repercussions in some markets already.
Mark Denny, head of global markets dealing at Investec Asset Management, said the fall in liquidity had increased the bid/ask spreads for large fixed-income and index trades, making trading more expensive.
