The economics of Grayscale’s GBTC outflow and fee compression

The cost of the fee gap

The 1.50% expense ratio for Grayscale Bitcoin Trust ETF (GBTC) creates a cost disadvantage against the 0.25% fee of iShares Bitcoin Trust ETF (IBIT). This 1.25 percentage point gap costs an investor $125 annually for every $10,000 held in the trust. Because the trust pays the fee through the sale of bitcoin, the cost results in fewer bitcoin backing each share over time. Both funds hold the same spot bitcoin through a qualified custodian, so the fee difference provides no additional exposure or unique strategy. BlackRock’s IBIT is the cheaper option for identical exposure. Grayscale CEO Michael Sonnenshein defends the 1.5% fee by citing the trust’s 10-year track record and market liquidity. He argues that lower fees from competitors reflect a lack of track record and a tactic to attract investors with fee incentives. While Grayscale focuses on its expertise as a crypto specialist, the fee remains the highest in the market. GBTC spent years as the only regulated US bitcoin vehicle, which allowed it to price the fee according to that era. On a $100,000 position, the gap amounts to $1,250 every year.

Market flows and IBIT dominance

Market flows show a massive migration toward BlackRock’s IBIT. On October 19, IBIT drew $665.2 million in net inflows, while GBTC saw a $54.9 million outflow. Fidelity’s FBTC lost $83.6 million on that same day. Total net assets for all US spot bitcoin ETFs reached $105.46 billion on October 19. IBIT currently holds $65,268,520,240 in net assets, whereas GBTC holds $10,600,000,000. This movement shows that investors favor the lower cost of IBIT. IBIT took only 96 trading days to close the substantial gap with GBTC. Bitcoin prices dropped 24.49% over the past year, and both funds dropped with it. GBTC traded at $63.14 and IBIT at $46.27 on October 19. Cumulative net inflows for IBIT reached $65,567,976,023.66, while GBTC saw cumulative net outflows of $27,943,497,955. The divergence in flows suggests a targeted bitcoin trade concentrated in the largest and most liquid fund. Does the liquidity of IBIT justify the massive concentration of capital in a single issuer?

The tax hurdle for long-term holders

Taxable account holders face a heavy hurdle when they attempt to move from GBTC to cheaper competitors. Selling GBTC in a taxable account triggers a capital gains tax because the sale counts as a disposition of assets. Investors who bought GBTC at much lower prices before the January 2024 conversion to an ETF face embedded capital gains that could potentially exceed the total savings gained from moving to a lower-cost fund like IBIT. For these holders, the tax bill can outweigh many years of fee savings. The math changes for those using an IRA, where selling GBGB to buy IBIT carries no tax consequence. You should check the specific cost basis of your holdings with a tax professional before you decide to move. Another option for those with large gains is to direct all new money toward IBIT while leaving existing GBGB shares in place. Recent buyers might find that some taxable GBTC lots show only small gains or losses because both funds fell over the past year.

Redemptions and bitcoin price impact

The selling pressure from GBTC outflows can influence the price of bitcoin. In the weeks following the January 2024 ETF approvals, Grayscale transferred 16,712 Bitcoins, worth more than $726 million, to Coinbase to fund redemptions. This movement occurred in batches of up to 1,000 BTC. While these transactions represent a small fraction of the 19.6 million BTC in circulation, they contribute to market volatility. Market pundits noted that the mass exodus from GBTC in January was attributed to the launch of spot Bitcoin ETFs. The pressure from these outflows can impact the market for several months as investors relocate to cheaper alternatives.
