f the April 2010 Triennial Central

f the April 2010 Triennial Central Bank Survey1 1. Turnover on the global foreign exchange market
 Global foreign exchange market turnover was 20% higher in April 2010 than in April 2007, with average daily turnover of $4.0 trillion compared to $3.3 trillion. The increase was driven by the 48% growth in turnover of spot transactions, which represent 37% of foreign exchange market turnover. Spot turnover rose to $1.5 trillion in April 2010 from $1.0 trillion in April 2007.
 The increase in turnover of other foreign exchange instruments was more modest at 7%, with average daily turnover of $2.5 trillion in April 2010. Turnover in outright forwards and currency swaps grew strongly. Turnover in foreign exchange swaps was flat relative to the previous survey, while trading in currency options decreased.
 As regards counterparties, the higher global foreign exchange market turnover is associated with the increased trading activity of “other financial institutions” – a category that includes non-reporting banks, hedge funds, pension funds, mutual funds, insurance companies and central banks, among others. Turnover by this category grew by 42%, increasing to $1.9 trillion in April 2010 from $1.3 trillion in April 2007. For the first time, activity of reporting dealers with other financial institutions surpassed inter-dealer transactions (ie transactions between reporting dealers).
 Foreign exchange market activity became more global, with cross-border transactions representing 65% of trading activity in April 2010, while local transactions account for 35%.
 The percentage share of the US dollar has continued its slow decline witnessed since the April 2001 survey, while the euro and the Japanese yen gained relative to April 2007. Among the 10 most actively traded currencies, the Australian and Canadian dollars both increased market share, while the pound sterling lost ground and the Swiss franc declined marginally. The market share of emerging market currencies increased, with the biggest gains for the Turkish lira and the Korean won.
 The relative ranking of foreign exchange trading centres has changed slightly from the previous survey. Banks located in the United Kingdom accounted for 36.7%, against 34.6% in 2007, of all foreign exchange market turnover, followed by the United States (18%), Japan (6%), Singapore (5%), Switzerland (5%), Hong Kong SAR (5%) and Australia (4%).
