The multi-billion dollar question posed by BlackRock's bitcoin ETF move

Quick Take

  • BlackRock’s recent move to file for a spot bitcoin ETF has triggered widespread speculation about how the market could change if the fund is approved.
  • The Block spoke with Sui Chung, the CEO of Kraken-subsidiary CF Benchmarks that provides the index set to be used by spot bitcoin ETFs being proposed by BlackRock, Valkyrie and WisdomTree.

Bitcoin's price has surged this month, rising nearly 14% in the wake of BlackRock's move to file for a spot bitcoin ETF that was quickly followed by other asset managers.

While most attention over the next few months will be on the U.S. Securities and Exchange Commission's response, as the regulator has yet to approve a spot bitcoin fund, the filings pose a larger question of just how much the funds could start to affect the broader market, and price of bitcoin, should they ultimately get the green light.

The Block spoke with Sui Chung, the CEO of Kraken-subsidiary CF Benchmarks that provides the index set to be used by spot bitcoin ETFs being proposed by BlackRock, Valkyrie and WisdomTree.

Chung, who says he's been intimately involved in the bitcoin ETF filing process over the years, spoke about what makes BlackRock's recent filing different from previous efforts. He also spoke about the size of the potential market for the funds.

BlackRock's Bitcoin ETF move

The Block: How was CF Benchmarks involved in BlackRock's recent move to file for a spot bitcoin ETF?

Sui Chung: CFB is the provider of the index BRRNY, Bitcoin Reference Rate — New York Variant, that will be the NAV for the fund.

The Block: How is this latest filing ETF different from ones that have been tried in the past? Ones that didn't receive approval?

Sui Chung: CF Benchmarks has been involved in more bitcoin ETF filings than any other company in the world. Of the 13 filings I think there have ever been, seven have used a CF Benchmarks index.

Once the S-1 is filed, what actually matters is the 19-b4 process, and in this case Nasdaq has to argue why the listing of this ETF will not compromise the exchange vis-à-vis the Securities and Exchange Act. So what's different is something called SSA with bitcoin spot market, which you will find on page 36 of Nasdaq's 19-b4. That has never featured in any previous 19-b4 by any national stock exchange in the U.S. attempting to rule change to allow a bitcoin ETF. So that is the thing that is different.

The Block: What does it do?

Sui Chung: It seeks to address the Commission's concerns that it has previously stated in its disapprovals of other 19-b4 processes. Previously, disapprovals have been stated by the SEC because there are insufficient measures taken by the listing exchange to ensure that there are mechanisms in place to impede and detect manipulative trading, potential manipulation of the shares of the ETF. It's the listing exchange that needs to have this in place.

Nasdaq moves to address concerns

The Block: So theoretically, Nasdaq has made changes to address these concerns?

Sui Chung: If you read the actual 19-b4, which is all public, this is something that Nasdaq proposes to put in place to to be able to fulfill that requirement that the SEC has.

The Block: How much has CF Benchmarks worked with some of these other parties to address these concerns?

Sui Chung: I think it's fair to say that it's a collective effort to understand, to interpret what that bar looks like. The SEC puts a bar there. So obviously, collectively, we analyze, 'okay, how can that bar be met? What have people tried before, which obviously wasn't enough, and so therefore where is that bar? What does reaching that bar look like? And what can we do to to meet that bar?'

The Block: So what's changed?

Sui Chung: I'd point you to the Nasdaq's words. They're public. They're in the filing. They call it the Spot BTC SSA. So this Spot BTC SSA is expected to have the hallmarks of a surveillance sharing agreement between two members of the ISG.

The Block: How long could this approval process last?

Sui Chung: There is a standard amount of time, and that standard amount of time is 45 days. However, the SEC has the ability to extend that by another 45 days. And then secondly, after that 90 days is up, they can also extend it. It's not quite an extension...but it's another way to delay it basically. So they can stretch it out, I think in total of 230 days, before they have to finally come up with either a disapproval or nothing. And it's the nothing that means you can go. 

The billion-dollar bitcoin question

The Block: If a spot is eventually approved, how do you see that changing the broader bitcoin market? Who influences who here? Will the ETFs just follow the market, or will they start to influence it? 

Sui Chung: That's the sort of multi-billion dollar question. If we think about ETFs as a class of instruments, I think in the U.S., something like 60% of the investing public holds at least one ETF. If you say that's the potential audience for this product, that's a big audience.
