[DigitalToday reporter Jinju Hong (홍진주)] BlackRock, the world's largest asset manager, has launched a new ETF that combines gains in Bitcoin prices with options premium income, but the market is also raising controversy over the fund's profit structure. BlackRock described it as a product aimed at institutional investors seeking stable cash flow, but some analysts criticised it as a "yield trap," saying its structure can limit investor returns in rising markets.

Cryptocurrency outlet Cryptopolitan reported on June 17 (local time) that BlackRock's iShares Bitcoin Premium Income ETF (BITA) began trading on the Nasdaq on June 16.

BITA holds both spot bitcoin and IBIT, BlackRock's spot bitcoin ETF. It applies an overwrite strategy by selling call options each month on about 25 to 35 percent of the portfolio. Investors can receive regular distributions of premium income generated in the option-selling process.

BlackRock said the structure can provide stable cash flow while retaining some of bitcoin's upside potential. Robert Mitchnick, BlackRock's head of digital assets, introduced BITA as a "hybrid bitcoin exposure product" and said it aims for an annual return in the mid-to-high single digits while tracking about 70 percent of IBIT's gains. He said it "could be a fairly attractive product" and stressed it could offer a new option for institutional investors who felt burdened by bitcoin investments that do not generate cash flow.

Market assessments are mixed. On-chain and macro analysis firm 10X Research said in a report on the same day that BITA is structured to mechanically sell call options each month regardless of market conditions. 10X Research said a bitcoin call-writing strategy can be effective in certain market environments, but it does not always guarantee high returns.

If a bull market develops strongly, investors forgo a significant portion of bitcoin's price gains because of the option selling. If markets move sideways or fall, option premiums can offset some losses but cannot prevent the decline itself.

10X Research has previously said bitcoin holders are failing to tap annual option premium opportunities worth about $7 billion, but added that actual outperformance occurs only in some periods when specific conditions are met. It therefore argued that a product structure that sells call options the same way each month without considering market conditions could lower expected returns.

The controversy does not stop at the product's returns. The market also sees BlackRock's BITA as potentially affecting the bitcoin options market itself. If large institutional funds systematically participate in call-writing strategies, it could create pressure to lower implied volatility in the options market. Bitcoin 30-day implied volatility has shown a declining trend in recent years alongside the spread of overwrite strategies. Some observers say structural changes in the bitcoin options market are possible if BlackRock, which currently runs about $48.6 billion in spot bitcoin ETFs, directly becomes a supplier of options premiums.

BlackRock presented financial advisory firms, insurers and pension funds as BITA's main customer base. These institutions have shown interest in bitcoin's growth potential but have been cautious about investing because it is an asset that does not generate returns. Mitchnick said, "One reason institutions have hesitated to include bitcoin in the past was that it has no cash flow," adding, "BITA is a product designed to solve this problem."

BITA charges an annual management fee of 0.65 percent and had net assets of about $10.5 million as of launch. The market expects it to compete with the existing NEOS Bitcoin High Income ETF, and Goldman Sachs is also pushing to launch a product with a similar structure.

Market conditions are not entirely favourable. U.S.-listed spot bitcoin ETFs recorded net outflows of about $64 million in a single day recently, and cumulative net outflows in June were tallied at more than $2.1 billion. Bitcoin is trading near $65,000.

Ultimately, BITA is structured to provide stable cash flow in exchange for giving up some of bitcoin's upside potential. Whether it becomes a new bitcoin investment tool for institutions or draws criticism for limiting returns in rising markets will depend on future market trends.
