Bitcoin's Hidden Cost: A $25 Million Discrepancy on Wall Street

The $25 million Bitcoin glitch refers to a discrepancy in the cost of holding Bitcoin exposure through regulated products on Wall Street. Two trading desks can hold similar economic risk, but pay different amounts due to differences in collateral systems and margin treatment.

A study by Purdue University professor Mindy Mallory compared matched observations between BlackRock's iShares Bitcoin Trust (IBIT) options and CME Bitcoin futures contracts. The results showed that the annualized carry embedded in CME futures exceeded the fee-adjusted carry reconstructed from IBIT options by an average of 2.581 percentage points.

For a $1 billion position, this difference would correspond to approximately $25.81 million over a full year. However, the study notes that this is not a fixed fee and varied substantially across dates.

The disparity in cost can be attributed to the fact that different products are placed into separate securities, options, and futures systems, which do not behave like one integrated market. This makes it difficult for arbitrage capital to move frictionlessly between systems.
