There has been a sharp uptick in the high-value bond ETF trades in the last 12-months which most investors are attributing to activity from large institutional investors. Transactions are up as much as 36% on some platforms from the previous year. This has been part of a longer more ongoing trend that has been successful for many bond funds. Since the GFC, investors have questioned the resiliency of these funds to economic downturns, but regulators and investors alike are pleased with their performance in the covid pandemic. Just as important to this is the support from the Fed and Fiscal policy to the economy. Stepping in with bond relief has helped these ETFs. Finally, the increase in investment in bond ETFs has actually led to tighter underlying spreads in bond markets themselves and reflects better liquidity.
Finsum: Many believe that over-investment in index funds could be disruptive to equity volatility over time, but it appears to be stabilizing bond spreads.
