Market risk is one of the most interesting and complex areas of risk management. Defined by the European Banking Authority as, the risk stemming 'from all the positions included in banks' trading book as well as from commodity and foreign exchange risk positions in the whole balance sheet,' and by the Basel Committee as the risk that the value of an investment will fall due to market factors, market risk is a huge deal for banks and funds.
It's the risk that the bank loses money following a collapse in the S&P 500. It's also the risk that the bank loses money following a sudden plummeting and loss of liquidity in the bond markets. And it's the risk that the bank makes massive losses in derivatives held in 'off-balance sheet vehicles' which suddenly become worth nothing when the whole market is re-calibrated (as in the 2008).
Market risk is a massive, complex, highly quantitative area. "There are loads of aspects," says a senior market risk manager at a Japanese bank in London. "You can be asked anything about regulations, risk measures, hedging, pricing or stress-scenarios." Manraj Kular, a consultant in market risk at recruitment firm Hudson, confirms that candidates need to anticipate questions on measuring risk, regulation, stress-testing and the risks associated with particular financial instruments.
"I usually ask about Value at Risk (VaR)," says Michael Bryant, managing director of risk consulting firm InDelta and a former managing director responsible for financial markets risk measurement at ING. "I also give the people I'm interviewing a particular financial instrument and ask them to describe the market risk and the way the price will change in response to market events."
Beyond the most junior levels of market risk, interview questions will be highly specific to the kinds of securities you're working with, says Alex Jenkins at risk focused recruitment firm JCW: "The breadth is enormous."
