Transactions even in developed countries such as the US thinned out during the 2010 games in South Africa as buyers and sellers put watching soccer before global politics and economic reports, according to the ECB's 2012 study.

In the 2010 tournament, Chilean traders were almost as likely to stop work during matches that didn't include the national team, which was ousted before the quarterfinals. Trading plunged 79 per cent during games between other countries.
When Argentina's national team was playing, trading tumbled 80 per cent in Buenos Aires. Brazil's team spurred a 75 per cent decline in local volumes, while US games reduced trading by 43 per cent. In European countries, volume dropped 38 per cent on average. Trading typically fell in the build-up to matches and stayed below normal until 45 minutes after the end.
"Markets were following developments on the soccer pitch rather than in the trading pit," ECB economists Michael Ehrmann and David-Jan Jansen wrote in the study. Ehrmann now works for the Bank of Canada in Ottawa, while Jansen is a researcher at the Dutch central bank in Amsterdam.
Chile's obsession with the World Cup may be explained partly by its modern history, which left the country politically polarised and emotionally repressed, according to Patricio Carvajal, the coordinator of the center for social studies of soccer at the University of Chile in Santiago.

The military dictatorship that ruled from 1973 to 1990 imposed curfews and suspended the right to free assembly. Just 18 per cent of the adult population attended at least one performing arts event in 2012, less than half the rate in the United States, based on data from the Chilean National Statistics Institute and the National Endowment for the Arts in the US.
"Chileans have few forums for emotional expression but soccer is a space where emotion is permitted," Carvajal said a May 28 interview.
In the 2010 World Cup, Chile progressed to the second round before being knocked out. This year, the country has a 1.9 per cent chance of winning, compared with favourite Brazil's 22 per cent, according to calculations by Bloomberg Sports.
Chile's team is led by midfielder Arturo Vidal of the Italian professional club Juventus and forward Alexis Sanchez of Barcelona. It's in one of the toughest groups, with Spain and the Netherlands, which placed first and second in 2010.
"Ardent Chilean fans are convinced that the best generation in the country's soccer history should fear no one," Tiago Severo, an economist at Goldman Sachs Group in New York, wrote May 27 in a report analysing how national markets would react in the event of a World Cup victory.
The bank said winning countries' markets typically outperform global stocks in the month after the final. Spain's benchmark IBEX 35 returned 12 per cent in the month after the 2010 World Cup, almost double the gains for the MSCI World Index.
Chile's benchmark IPSA stock index has climbed 1 per cent this year in dollar terms, trailing the 4.3 per cent advance for the Standard & Poor's 500 Index as well as the 4.9 per cent increase in Brazil's Ibovespa gauge.
President Michelle Bachelet urged companies on May 15 to allow flexibility for people to watch matches. She's also planning to travel to Brazil to root for the Chilean team.
"All countries in Latin America fervently support their national side, but it seems that in Chile there is an emotional spillover into our working lives," Carvajal said. "It's an explosion of national sentiment. Chile's soccer history is a history of defeat. It's reclaiming suffering, adversity and struggle."
And forgetting about the stock market for a while.
