			 For much of the year, ultra-cheap cash and faith in a recovering 
			global economy has kept equities on the rebound. In the first half 
			of 2015, trading volumes jumped 36 percent worldwide, according to 
			the World Federation of Exchanges, though the rise was a far more 
			modest 5 percent after stripping out mainland China's rollercoaster 
			stock market. 
			 
			That in turn has helped banks squeeze out more trading revenue 
			despite pressure on all sides from increased automation, intense 
			competition and post-crisis regulation. First-half equities revenue 
			grew 18 percent at the top 10 investment banks, to $25 billion, 
			according to data from research firm Coalition. 
			 
			But after last month's China-fueled spike in the VIX volatility 
			gauge to its highest since 2008-2009, flows are drying up and major 
			indexes like Japan's Nikkei or the S&P 500 are making daily moves of 
			3 to 8 percent. 
			  
			
			  
			 
			"Volatility is generally good for trading desks but when you see 
			Japan up 8 percent overnight, or Wall Street down 400 points ... The 
			risk is just too much," said Mark Ward, head of execution trading at 
			Sanlam Securities in London. 
			 
			"Volatility like this is horrendous. It's volatility on steroids." 
			 
			It may already have inflicted some pain, albeit manageable, on 
			investment banks. While curbs on risk-taking have reduced banks' 
			exposure to proprietary trading, J.P.Morgan analysts warned last 
			week that August's bruising sell-off may have led to losses and 
			dented future trading and deal flows. 
			 
			"Investment banks are not immune to the market movements," they 
			wrote in a note to clients. Beyond hits to profitability, the 
			analysts forecast double-digit falls in equities and fixed-income 
			revenue for the third quarter. 
			 
			The surge in the market's fear gauge is blamed on fundamental and 
			technical factors alike. China's slowdown is alarming markets at the 
			very time when the U.S. Federal Reserve is weighing its first 
			interest-rate hike since the 2008 meltdown, while trend-following 
			algorithms exacerbate losses. 
			 
			Whatever the cause, global equities fund flows are now in negative 
			territory year-to-date, according to BofA-Merrill Lynch research on 
			Friday. Investors are complaining of "untradable" markets and a 
			perceived lack of liquidity, strategists said, even if a big shock 
			to the system has yet to materialize.

			"The increased volatility and (Fed-related) uncertainty ... has 
			reduced flow to a trickle, with both the single-stock traders and 
			derivative sales reporting a paucity of directional volumes," 
			Deutsche Bank Managing Director Nick Lawson wrote in a note to 
			clients on Friday. 
			It is still too early to say whether the current turmoil will derail 
			a recovery in trading revenues. 
			 
			"It's not a hugely positive sign for volumes to pull back so quickly 
			after such volatility ... But this might be a slight pause as 
			opposed to a reversion in the trend," said Craig Viani, Vice 
			President at consultancy Greenwich Associates. 
			 
			Industry watchers say losses are likely to have been in the 
			manageable range of $50 million to $60 million. The jury is still 
			out on whether the most active hedge funds will retrench, said 
			George Kuznetsov, head of research at Coalition. 
			 
			In many ways, the safest bet is on volatility itself. Crossbridge 
			Capital's Manish Singh said he was using volatility-linked 
			derivatives to trade on the Fed's policy meeting next week. 
			 
			"Whether the decision from the Fed is to hold or tighten policy ... 
			expect volatility to remain elevated," said Deutsche Bank's Lawson.
