The Financial Accounting Standards Board (FASB) has adopted Fair Value Accounting for Bitcoin, effective for fiscal years starting after December 15, 2024. This new rule mandates that companies report Bitcoin at current market prices, enhancing transparency and potentially encouraging its use as a treasury reserve asset.Large corporations like MicroStrategy and Tesla will benefit from simplified financial reporting, allowing them to recognize both gains and losses from Bitcoin holdings. This regulatory change is seen as a catalyst for increased institutional confidence in Bitcoin, with potential implications for its market value.
