As of August, each of Schwab's core bond funds attracted over $1 billion in inflows, with two ETFs (including Schwab 5-10 Year Corporate Bond ETF SCHI, Schwab U.S. TIPS ETF SCHP, and Schwab Aggregate Bond ETF SCHZ) seeing nearly $2 billion in inflows. Investors typically turn to safe-haven assets like U.S. Treasuries during market volatility or when seeking attractive yields relative to risk assets, or as a core component to balance their portfolios. These bond ETFs also offer advantages such as low cost, built-in diversification, transparency, and intraday liquidity.
