VanEck’s muni bond ETF kept all 49 holdings intact during its fourth quarter rebalance but executed an internal rotation favoring higher-yielding funds over investment-grade names, according to index data from VettaFi.
The shift reflects positioning for investors seeking tax-exempt income in a market where the S-Network Municipal Bond Closed-End Fund Index, which the VanEck Vectors CEF Municipal Income ETF (XMPT) tracks, shows a 6.3% yield compared to the 1-year Treasury rate of 3.5%, according to the index’s factsheet.
During the December 31 rebalance, XMPT reduced exposure to quality-focused holdings like the Nuveen Quality Municipal Income Fund, which saw its weight drop 0.89%, and the Nuveen Municipal Credit Income Fund, down 0.70%, according to the data.
Capital flowed instead to Nuveen Municipal High Income Opportunity Fund, which gained 0.53% in index weight, and BlackRock MuniVest Fund II, up 0.31%, according to the data. BlackRock Municipal Income Trust added 0.24% while BlackRock MuniYield Quality Fund increased 0.22%.
The rotation moved capital from the largest quality-focused holdings into higher-yielding, credit-focused funds. The index methodology uses a modified total net assets weighting system designed to provide exposure across different segments of the tax-exempt closed-end fund market, according to VettaFi.
The rebalance maintained the index’s sector composition at 67.7% leveraged funds, 25.7% leveraged high yield funds, and 6.6% unleveraged funds, according to the factsheet.
Muni Bond ETF Faces BlackRock Mergers
Five BlackRock municipal bond closed-end funds in the index have shareholder-approved merger agreements expected to close in February 2026, according to the data. The funds include the BlackRock MuniVest II, the BlackRock MuniVest, the BlackRock MuniYield, the BlackRock MuniYield Quality II, and the BlackRock Investment Quality Municipal Trust.
The mergers remain subject to regulatory approval and will likely trigger additional index changes in the first quarter of 2026, the data notes.
XMPT, the ETF tracking the index, generated $9.85 million in net inflows over the past month and returned 1.07% compared to the ETF Database category average of 0.23%, according to ETF Database. The fund holds $200.5 million in assets and charges a 1.97% expense ratio.
