2021 ETF Inflows Hit $900B

The U.S. ETF industry closed a record year with a record month.

Edited by: Dan Mika

U.S.-listed ETFs took a net inflow of just under $99.4 billion in December, shattering the previous one-month record of $91.2 billion set in November 2020 and capping off a record-breaking year for the industry as it breached the $900 billion inflow mark for 2021.

That figure is well above the $507.4 billion generated in 2020, and nearly double the $476.1 billion that flowed into the industry in 2017.

According to ETF.com data provider FactSet, the U.S. ETF industry ended 2021 with $7.21 trillion in assets under management. The December figures are inclusive of the mid-December rebalances of the Nasdaq-100 and major indexes from S&P Dow Jones and CRSP that underlie popular broad-market ETFs issued by Vanguard, BlackRock and Invesco.

Those index rebalances caused nearly $38 billion in inflows on Dec. 16 alone, most of which were later withdrawn once the funds were realigned with the indexes they tracked.

While U.S. equities easily led among the asset classes, almost every asset class saw at least a doubling in their ETF asset size. The only ETF classes with net outflows were more U.S. fixed income, commodities and leveraged funds, suggesting that those somewhat bearish strategies lost their sheen.

Broad Market Ends Dominant Year

With the S&P 500 gaining nearly 28% in the year and notching a near record of 70 all-time high closes, it’s no wonder broad equity ETFs ended December squarely on top of the inflows list.

The SPDR S&P 500 ETF Trust (SPY) utterly dominated inflows for the month, with just shy of $20.9 billion in new assets flowing into the oldest ETF in the U.S. Far behind were the Invesco QQQ Trust (QQQ) and the Vanguard Total Stock Market ETF (VTI), with $6 billion and just short of $4.5 billion, respectively.

On the fixed income side, the iShares 20+ Year Treasury Bond ETF (TLT) added $2.1 billion in new assets as bond investors reacted to the Federal Reserve pivoting toward a tighter monetary policy in 2022 to wrangle inflation down. The iShares iBoxx USD High Yield Corporate Bond ETF (HYG) added just shy of $3.3 billion in assets.

The ProShares UltraPro QQQ (TQQQ) also added $1.8 billion in new assets during the month, making it the only leveraged fund to appear in the top 10.

Factors, Inflation Hedges Sell Off

Three of BlackRock’s largest factor-driven index funds suffered deep outflows during the month, likely due to the relative appeal of broader-market ETFs. The iShares MSCI USA Quality Factor ETF (QUAL) saw just over $3 billion in outflows on the month, while the iShares MSCI USA Momentum Factor ETF (MTUM) and the iShares MSCI USA Min Vol Factor ETF (USMV) lost $1.9 billion and $1.4 billion, respectively.

The Vanguard S&P 500 ETF (VOO) suffered a rare outflow of $1.8 billion in the month, which is likely attributable to year-end profit-taking.

Three common inflation-protection ETFs also suffered outflows, despite the Consumer Price Index hitting an annualized 6.8% in November after months of prolonged inflation. The inflation-adjusted Treasury-holding Quadratic Interest Rate Volatility & Inflation Hedge ETF (IVOL) lost $913.2 million on the month, while the Schwab U.S. TIPS ETF (SCHP) lost $718.3 million. The SPDR Gold Trust (GLD) decreased by $967.8 million, extending its yearlong slide.

However, the iShares TIPS Bond ETF (TIP) gained more than $1.1 billion in the period, suggesting that some investors aren’t completely ready to move assets out of some of the safest securities on the market.

2021’s Biggest Winners & Losers

Vanguard once again dominated among ETFs with the 10 largest net inflows on the year, holding six places on the list. VOO led, with $46.6 billion in new assets, while VTI took in just over $44 billion. SPY was a distant third, at $35.2 billion in net new assets.

The only fixed income entrants among the top 10 were the Vanguard Total Bond Market ETF (BND) and the Vanguard Short-Term ETF (BSV), with $18.7 billion and $13.4 billion in new assets, respectively.

On the bottom end of the flows list, the iShares iBoxx USD Investment Grade Corporate Bond ETF (LQD) saw the largest outflows, with $14.2 billion pulled by investors, followed by GLD, at just shy of $10.8 billion.
