Charles Schwab’s (NYSE: SCHW) Schwab ETF OneSource commission-free exchange traded funds platform is already the largest platform of that kind in terms of number of offerings and that growth is continuing with the addition of six Deutsche Asset & Wealth Management (Deutsche AWM) funds, including some well-known currency hedged ETFs.

In a statement out Monday, Deutsche AWM and Schwab confirmed the following Deutsche AWM ETFs are joining the ETF OneSource platform: Deutsche X-trackers MSCI EAFE Hedged Equity ETF (NYSEArca: DBEF), Deutsche X-trackers MSCI Emerging Markets Hedged Equity Fund (NYSEArca: DBEM), Deutsche X-trackers MSCI EMU Hedged Equity ETF (NYSEArca: DBEZ) , Deutsche X-trackers MSCI All World ex US Hedged Equity ETF (NYSEArca: DBAW), Deutsche X-trackers MSCI All World ex-US High Dividend Yield Hedged Equity ETF (NYSEArca: HDAW) and the Deutsche X-Trackers Municipal Infrastructure Revenue Bond Fund (NYSEArca: RVNU).

“We are excited that Deutsche X-trackers will be included on Schwab ETF OneSource,” said Fiona Bassett, Head of Passive in the Americas, in the statement. “As part of the program, we are able to expand the exposure of our Deutsche X-trackers suite and offer investors greater access to our innovative, currency hedged suite through the broadest commission free ETF offering.”

Schwab’s ETF OneSource platform is also added John Hancock Multifactor Large Cap ETF (NYSEArca: JHML), John Hancock Multifactor Mid Cap ETF (NYSEArca: JHMM), John Hancock Multifactor Consumer Discretionary ETF (NYSEArca: JHMC), John Hancock Multifactor Financials ETF (NYSEArca: JHMF), John Hancock Multifactor Healthcare ETF (NYSEArca: JHMH) and John Hancock Multifactor Technology ETF (NYSEArca: JHMT). John Hancock, a recent entrant to the ETF industry, may be hoping to attract greater attention and asset inflows through the commission-free ETF trading platform.

With original members State Street (NYSE: STT), Guggenheim, Invesco’s (NYSE: IVZ) PowerShares, ETF Securities, U.S. Commodity Funds and Schwab’s own lineup of ETFs, OneSource now offers select ETFs from 15 issuers on a commission-free basis. The entire list can be viewed here.

In June, J.P. Morgan Asset Management, the ETF arm of J.P. Morgan Chase (NYSE: JPM) becomes the newest issuer of Schwab ETF OneSource as all three J.P. Morgan ETFs will be available to Schwab clients commission-free. Those ETFs include the JPMorgan Diversified Return Global Equity ETF (NYSEArca: JPGE), JPMorgan Diversified Return International Equity ETF (NYSEArca: JPIN) and the JPMorgan Diversified Return Emerging Markets Equity ETF (NYSEArca: JPEM).
