Cryptocurrency Accounting

The accounting treatment of cryptocurrency holdings has been unsettled for years. Traditionally, companies held crypto as an indefinite-lived intangible asset, testing annually for impairment. In September 2023, the FASB issued ASU 2023-08, which permits (but does not require) companies to elect a fair-value measurement option for crypto holdings—a radical shift that allows quarterly remeasurement through profit and loss, similar to investment securities.

The legacy treatment: intangible asset with annual impairment

Before 2023, there was no explicit accounting standard for cryptocurrency. In the absence of guidance, the SEC staff and practitioners converged on treating crypto as an indefinite-lived intangible asset under ASC 350, the goodwill and intangibles standard. This made intuitive sense: crypto has no physical form, generates no cash flows, and has indefinite useful life.

Under ASC 350, an indefinite-lived intangible asset is tested for impairment annually (or whenever a triggering event occurs). The test compares the quoted fair value—the trading price on an exchange like Bitcoin at, say, $40,000 per coin—to the book value (cost basis). If the quoted price exceeds book value, no impairment. If the quoted price falls below book value, an impairment loss is recognised, and the carrying amount is written down to fair value.

This treatment created a stark asymmetry: gains were not recognised in the income statement until the crypto was sold (realised gain), but losses were recognised as soon as the price fell below cost. If a company bought Bitcoin at $50,000 and the price rose to $60,000, the balance sheet carried the asset at $50,000 and net income was unaffected. Only when the company sold at $60,000 was a $10,000 gain recognised. By contrast, if the price fell to $40,000 and remained there, an impairment loss of $10,000 was recorded immediately.

This asymmetry favoured holders: you could report gains whenever you wanted (by selling) but were forced to recognise losses annually. It also meant that a company’s net income was volatile if it held volatile crypto, because losses flowed through the income statement while unrealised gains did not.

Impairment testing was simple but produced conservative reported values

The annual impairment test was straightforward in theory: look up the quoted price of Bitcoin or Ethereum on a major exchange, compare to book value, write down if lower. In practice, questions arose. Which exchange price was authoritative? Should a company use the price at period-end, an average, or a spot price? Should illiquidity discounts apply? For most companies, these were immaterial details—they used the spot price at quarter-end from a standard source like CoinMarketCap—but for entities with material crypto holdings, the choice mattered.

A second issue: if an impairment loss was recognised in one year (say, Bitcoin fell from $50,000 to $40,000), could the loss be reversed in a subsequent year if the price recovered? Under ASC 350, reversals of impairment losses on indefinite-lived intangibles are prohibited. Once a loss is taken, it stays. So if Bitcoin recovered to $45,000, the asset remained at $40,000 on the balance sheet, and the $5,000 recovery was not reflected in the financial statements. This ratchet effect further depressed reported values for holders in volatile markets.

ASU 2023-08 introduces an optional fair-value measurement approach

In September 2023, after years of calls from constituents and growing controversy over crypto accounting, the FASB issued ASU 2023-08, which adds a fair-value option to ASC 825 (financial instruments). Under this new rule, a non-financial entity can elect, at inception or upon adoption, to measure its crypto holdings at fair value through profit and loss.

The election is per-entity and is not reversible (once chosen, the company is locked in to fair value for that crypto holding). If elected, the company remeasures the crypto at fair value each reporting period and recognises all gains and losses—realised and unrealised—in net income. This produces quarterly volatility but also transparency: the balance sheet always reflects the current market value of the holding.

For a company that bought Bitcoin at $40,000 and the price is now $50,000, the difference (plus or minus subsequent fair-value changes) flows through the income statement each quarter, not just when the crypto is sold. This mirrors how investment securities are treated under fair-value options under ASC 320 or ASC 321.

The election decision is strategic and largely irreversible

Choosing fair-value measurement has financial reporting consequences. Quarterly earnings become more volatile, because crypto price swings flow through the income statement. For a company with $100 million in Bitcoin holdings, a 10% price swing creates a $10 million unrealised gain or loss each quarter. Earnings per share and other per-share metrics bounce around.

However, the fair-value option also provides transparency. Readers of the financial statements know exactly what the crypto is worth and see every price move. Under the legacy indefinite-lived intangible approach, a company could hold crypto for years without any update to its book value if the price rose (no gain recognised until sale). The fair-value option eliminates this hiding place.

The election is available to non-financial entities (corporations, partnerships, trusts). Financial institutions like banks and broker-dealers, which already mark most positions to fair value, are excluded—they are already accounting for crypto more transparently than non-financial companies were.

Transitional accounting: most companies have already adopted

ASU 2023-08 became effective for fiscal years beginning after December 15, 2024, but early adoption was permitted starting in 2023. Most companies with material crypto holdings have already elected the fair-value option, because the benefit of transparency and improved comparability outweighed the short-term earnings volatility. A company that had been forced to test for impairment annually, dragging losses to the income statement but hiding gains, found the fair-value approach more intuitive.

For companies that have not yet adopted, a choice awaits. Some may continue under the indefinite-lived intangible treatment, particularly if they hold small amounts of crypto and the quarterly fair-value remeasurement is considered immaterial. But materiality is a moving target—as crypto allocations grow, the fair-value option becomes harder to avoid.

Practical considerations: valuation and disclosure

Under the fair-value option, companies must identify a reliable price source. For major coins (Bitcoin, Ethereum), published prices from liquid exchanges like Coinbase are used. For smaller or less liquid tokens, valuation is harder; some companies use pricing services like Messari or Bloomberg Terminal. For illiquid or off-exchange holdings, models may be required, but these are rare for non-financial companies.

Disclosure requirements are extensive. Under ASU 2023-08, companies must disclose the method used to determine fair value, the quantities held, and the location in the balance sheet. For Level 3 fair-value estimates (e.g., illiquid tokens), full sensitivity analysis and rollforward are required, mirroring disclosures for other Level 3 assets.

The broader implication: evolving treatment of digital assets

ASU 2023-08 is a watershed. It signals FASB acknowledgment that crypto is not an ordinary intangible asset; it is a financial commodity with rapidly shifting value. The fair-value-option approach aligns crypto with how equities, bonds, and derivatives are treated for companies with portfolios. Over time, if crypto becomes more embedded in corporate treasury and investment strategies, the fair-value treatment will likely become the norm.

Some observers view the option—not a mandate—as a compromise: companies with smaller holdings can maintain the simpler indefinite-lived intangible method, while companies with large holdings move to transparency. However, as institutional adoption of crypto broadens, the indefinite-lived intangible approach will eventually feel antiquated.
