Charles Schwab launched its first exchange-traded funds that invest in U.S. government debt. The Schwab Short-Term U.S. Treasury ETF, the Schwab Intermediate-Term U.S. Treasury ETF and the Schwab U.S. TIPS ETF trade on NYSE Arca. The expense ratio is 0.14% for the TIPS ETF and 0.12% for the other two. For Schwab's clients, trading is commission-free.
