Risk and balance sheet management (continued)

Market risk 

Market risk arises from changes in interest rates, foreign currency, credit spread, equity prices and risk related factors such as market volatilities. The Group manages market risk centrally within its trading and non-trading portfolios through a comprehensive market risk management framework. This framework includes limits based on, but not limited to, value-at-risk (VaR), stress testing, position and sensitivity analyses.

VaR is a technique that produces estimates of the potential change in the market value of a portfolio over a specified time horizon at given confidence levels. For internal risk management purposes, the Group's VaR assumes a time horizon of one trading day and a confidence level of 99%. The Group's VaR model is based on a historical simulation model, utilising data from the previous two years trading results.

The VaR disclosure is broken down into trading and non-trading where trading VaR relates to the main trading activities of the Group and non-trading reflects the VaR associated with reclassified assets, money market business and the management of internal funds flow within the Group's businesses.

The Group's VaR should be interpreted in the light of the limitations of the methodology used, as follows:

·	Historical simulation VaR may not provide the best estimate of future market movements. It can only provide a prediction of the future based on events that occurred in the 500 trading day time series. Therefore, events more severe than those in the historical data series cannot be predicted.
·	The use of a 99% confidence level does not reflect the extent of potential losses beyond that percentile.
·	The use of a one day time horizon will not fully capture the profit and loss implications of positions that cannot be liquidated or hedged within one day.
·	The Group computes the VaR of trading portfolios at the close of business. Positions may change substantially during the course of the trading day and intra-day profits and losses will be incurred.

These limitations mean that the Group cannot guarantee that profits or losses will not exceed the VaR.

Market risk: GBM traded revenue

Note:

(1)	The effect of any month end adjustments, not attributable to a specific daily market move, is spread evenly over the days in the month in question.

Key points

·	The average daily revenue earned from GBM's trading, balance sheet management and other trading activities in Q1 2011 was £33.9 million, compared with £15.5 million in Q4 2010 and £39.7 million in Q1 2010. The standard deviation of these daily revenues was £19.9 million in Q1 2011, compared with £20.7 million in Q4 2010 and £19.7 million in Q1 2010. The standard deviation measures the variation of daily revenues about the mean value of those revenues.
·	An analysis of the frequency distribution of daily revenue shows that there were two days with negative revenue during Q1 2011, compared with eleven days in Q4 2010 and no days in Q1 2010. The most frequent result in Q1 2011 is a daily revenue of between £25 million and £30 million with ten occurrences compared with five occurrences in Q4 2010 and six occurrences during Q1 2010.

Key points

·	The credit spread VaR for Q1 2011 was lower than Q1 2010 primarily due to the exceptional volatility of the market data from the period of the financial crisis dropping out of the 500 days of time series data used in the VaR calculation. Credit spread VaR also reduced as the quality of the market data time series used in the ABS Mortgage Trading business was improved, moving from interpolated weekly data to daily observed time series. This change has improved the accuracy of the correlation between the different time series in the daily data. Additionally, the basis modelling between the cash and derivatives has been refined by introducing additional time series for the subprime and subordinated residential bonds, reducing the over-reliance on the commercial mortgage basis which was used as a conservative proxy.
·	CEM trading VaR reduced during Q1 2011 due to lower volatility combined with reduced exposures.
·	Non-Core VaR was slightly higher in Q1 2011 than for Q4 2010 due to increases in the market value of the exposures within the Structured Credit Portfolio (SCP) trading book, as credit indices continued to rally over the quarter.
·	The commodity VaR in Q1 2011 has reduced to a minimal level when compared with 2010 due to the sale of the Group's interest in the RBS Sempra Commodities joint venture.

Note:

(1)	Revised to exclude SCP and LAR portfolios, implemented in Q2 2010 and Q4 2010 respectively.

Key points

·	The general increase in total, Core and credit spread VaR is primarily due to a change in the time series used for the Dutch RMBS portfolio in RBS N.V. as more relevant and granular market data became available.
·	The total VaR at 31 March 2011 is lower than at 31 March 2010, due primarily to the disposal of a large portfolio of illiquid available-for-sale securities during 2010, and also due to the exceptional volatility of the market data from the period of the financial crisis dropping out of the 500 days of time series data used in the VaR calculation, which in particular impacted the credit spread VaR.

Note:

(1)	Mortgage-backed securities (MBS) include sub-prime residential mortgage-backed securities with a notional amount of £455 million (31 December 2010 - £471 million) and a fair value of £330 million (31 December 2010 - £329 million), all with residual maturities of greater than 10 years.

The SCP is within Non-Core. The risk on this portfolio is not measured or disclosed using VaR, as the Group believes this is not an appropriate tool for the banking book portfolio comprising illiquid debt securities. The main driver of the reduction in drawn notional is the depreciation of the US dollar and the amortisation of assets.
