In just a little over a month this year, asset outflows in emerging market exchange traded funds have already outpaced redemptions for all of 2013 as slow growth and currency concerns instigated a global sell-off.

The Vanguard FTSE Emerging Markets ETF (NYSEArca: VWO) and iShares MSCI Emerging Markets ETF (NYSEArca: EEM), the two largest emerging market ETFs, have experienced combined outflows of about $10.2 billion year-to-date, according to ETF.com. [Emerging Markets Outflows: Worse Before it Gets Better]

According to EPFR, for the week ended Feb. 5, emerging market equity funds lost $6.4 billion after a $6.3 billion outflow in the week prior, reports Robert Minto for Financial Times. [A January to Forget: ETFs Lose Almost $10 Billion]

Investors dumped about $18.6 billion in emerging market equities so far this year, compared to $15.3 billion in outflows for all of 2013.

“The outflows are not good news and from a macro perspective will have negative EM consequences by weighing on currencies, credit extension and ultimately the ability to consume,” analysts at Barclays told FT.

Bond funds saw almost $2 billion in outflows this week, compared to $900 million in outflows the week prior. However, in the ETF space, Treasury bond ETFs are attracting safe-haven investors, with the iShares 1-3 Year Treasury Bond ETF (NYSEArca: SHY) bringing in $3.7 billion in assets.

U.S. equity funds have been the least favorite asset as investors sold $8.6 billion in SPDR S&P 500 ETF (NYSEArca: SPY) over the past week.
