BlackRock swaps index ETF for active GGOV; $2B inflows

BlackRock replaced the index iShares Core International Aggregate Bond ETF (IAGG) with the active iShares Global Government Bond USD Hedged Active ETF (GGOV) in its target-allocation model portfolios. On May 28 GGOV traded roughly 40 million shares, a volume spike that trading data indicates will likely convert into more than $2 billion in inflows once custodial and reporting processes complete.

GGOV launched in late June 2025 and held about $45 million in assets before the surge. It had averaged fewer than 1,000 shares a day over the prior month.

The ETF is actively managed and concentrates on high-quality sovereign debt. About 87% of holdings are rated A or higher and the fund hedges currency exposure back to the U.S. dollar. The largest country exposure is the United States at roughly one-third of the portfolio, followed by Japan and China. The 30-day SEC yield is about 3.01% and the net expense ratio is 0.39%.

IAGG tracks a broad international investment-grade index excluding the U.S. and includes sovereign, corporate and securitized debt. It carries a larger share of BBB-rated and lower-quality corporate bonds. IAGG also hedges to the U.S. dollar, has a 30-day SEC yield near 3.06% and a net expense ratio of 0.07%.

Data provider TMX VettaFi projects the trading spike will appear as large inflows on official asset records after accounting procedures clear. Advisors who follow BlackRock’s models should see the allocation change recorded in client accounts once rebalancing is processed.

Michael Gates, lead portfolio manager for BlackRock’s Target Allocation ETF model portfolio suite, noted that “The regions at the forefront of adopting and deploying AI to drive productivity, margin expansion, and operational efficiency remain rooted in the U.S. and EM Asia. Market performance this year has generally rewarded those themes, while regions with more sensitivity to oil prices have not fared as well.” He said the team prefers an active fixed-income approach that can adjust duration, country weights and yield-curve exposure in response to macroeconomic data and central bank policy shifts.

BlackRock has increased the use of active ETFs in its model portfolios to gain exposure across U.S. equity, international equity and U.S. fixed income. Previously included active funds later attracted larger investor inflows after being added to the models. GGOV’s daily liquidity is expected to improve as assets scale.
