Mark-to-Market (Crypto)

What Is Mark-to-Market for Crypto?

Mark-to-market is the accounting practice of valuing an asset at its current market price rather than its historical purchase cost. When applied to crypto holdings, mark-to-market means a company must update the carrying value of its digital assets on the balance sheet to reflect the most recent observable market price at the end of each reporting period. Any difference between the prior carrying value and the updated fair value flows through the income statement as an unrealized gain or loss.

Before ASU 2023-08 took effect, U.S. GAAP did not have a crypto-specific accounting standard. Companies holding Bitcoin, Ether, or other crypto assets had to classify them as indefinite-lived intangible assets under ASC 350. That classification forced a one-directional impairment model: companies wrote values down when prices fell below the carrying amount but could never write them back up when prices recovered (short of selling). The result was financial statements that systematically understated the economic value of crypto portfolios during volatile markets.

The shift to mark-to-market under ASU 2023-08 brings crypto accounting closer to how other financial instruments are reported, providing investors with a more accurate picture of a company's crypto-related financial position.

How It Works

Under the new fair value framework codified in ASC 350-60, the mark-to-market process for crypto assets follows a structured approach each reporting period:

1. Identify all crypto assets in scope: the asset must be fungible, secured by cryptography, recorded on a distributed ledger, and not created or issued by the reporting entity or its related parties
2. Determine the principal market for each asset: the exchange or platform with the greatest volume and level of activity that the entity can access
3. Obtain the fair value at the measurement date using the price in the principal market (or the most advantageous market if no principal market is identifiable)
4. Record the change in fair value in net income: gains when the price has risen since the prior period, losses when it has fallen
5. Disclose required information: name, cost basis, fair value, and number of units for each significant crypto asset holding

Determining Fair Value

Fair value measurement follows the existing ASC 820 framework, which defines a three-level hierarchy based on the observability of inputs:

• Level 1: quoted prices in active markets for identical assets (e.g., Bitcoin price on a major exchange with high trading volume)
• Level 2: observable inputs other than Level 1 prices, such as quoted prices on less active exchanges or prices for similar crypto assets
• Level 3: unobservable inputs based on entity-specific assumptions, used when market data is scarce or nonexistent (common for illiquid or newly launched tokens)

For highly liquid assets like Bitcoin and Ether, Level 1 measurements are straightforward: multiple active exchanges publish real-time prices. The challenge arises with smaller tokens that trade on fewer venues or have low daily volume.

Principal Market Determination

Choosing the correct principal market is critical because it determines the price used for measurement. A company must evaluate which market has the greatest volume and level of activity for each specific crypto asset that the entity can access. This assessment considers:

• Trading volume and frequency on each exchange
• Whether the entity has an active account and can transact on that exchange
• Regulatory restrictions that may prevent access to certain venues
• Whether the price on a given exchange reflects an orderly transaction

Crypto assets trade across hundreds of exchanges globally, and prices can vary between venues. Unlike traditional securities with a consolidated tape, no single authoritative price source exists for most crypto assets. Companies must document their principal market determination and apply it consistently.

Transition to Fair Value

Entities adopting ASU 2023-08 apply a modified retrospective transition method. On the adoption date, the difference between the existing carrying amount (cost minus accumulated impairment) and the current fair value is recorded as a cumulative-effect adjustment to the opening balance of retained earnings. This one-time adjustment captures the unrealized gains that were suppressed under the old impairment model.

// Simplified transition example
// Bitcoin purchased at $30,000, impaired to $16,000, now worth $60,000

Prior carrying amount:         $16,000  (cost $30,000 - impairment $14,000)
Fair value at adoption date:   $60,000
Cumulative-effect adjustment:  $44,000  (credited to retained earnings)

// After adoption, each quarter:
// Q1 fair value: $65,000 → recognize $5,000 unrealized gain in net income
// Q2 fair value: $55,000 → recognize $10,000 unrealized loss in net income

Impairment-Only Model vs. Fair Value

Understanding the old approach highlights why the shift to mark-to-market matters. Under the previous impairment-only model:

The impairment model created a well-documented problem. MicroStrategy, one of the largest corporate Bitcoin holders, recorded approximately $2.2 billion in cumulative impairment charges under the old rules, even as the market value of its holdings significantly exceeded its purchase price. Those impairment charges reduced reported earnings without reflecting the corresponding economic reality of price recovery.

Use Cases

Corporate Treasury Holdings

Companies that hold Bitcoin or other crypto assets as part of their treasury strategy benefit most directly from mark-to-market accounting. Under the new rules, their balance sheets reflect the actual economic value of holdings each quarter, giving investors a clearer view of the company's financial position. This transparency can also make it easier for CFOs to justify crypto allocations to boards and auditors, since the accounting treatment now aligns with how these assets are managed.

Crypto-Native Companies

Exchanges, custodians, and crypto-native businesses that hold significant token inventories now report these holdings at fair value. For companies with large and diverse token portfolios, this creates a more accurate representation of their asset base, though it also means quarterly earnings will directly reflect market swings.

Investment Fund Reporting

While investment companies already measured most assets at fair value, Bitcoin ETFs and crypto funds benefit from the standardized treatment. Net asset value calculations now follow a consistent, codified framework rather than relying on ad hoc fair value determinations for the crypto portion of portfolios.

Stablecoin Issuers and Platforms

Entities that accept crypto assets as collateral or hold them during processing (such as stablecoin issuers or payment platforms) must now mark those transient holdings to market. For stablecoin ecosystems built on Bitcoin, such as platforms using USDB, the fair value treatment applies to any qualifying crypto collateral on the balance sheet.

Why It Matters

Mark-to-market accounting for crypto removes a longstanding barrier to institutional adoption. Under the old model, holding crypto on a corporate balance sheet created an accounting asymmetry that punished companies for price volatility even when the long-term trend was upward. CFOs had to explain impairment charges that did not reflect actual losses, and analysts had to adjust reported figures to approximate true economic value.

The new standard makes crypto holdings legible in the same language as other financial assets. For companies evaluating whether to hold Bitcoin or stablecoins as treasury assets, the fair value framework removes the accounting penalty that previously made such allocations unattractive. For a deeper analysis of corporate crypto treasury strategies, see the corporate treasury research.

The change also matters for crypto-native infrastructure. As more businesses hold digital assets for operational purposes (paying vendors, receiving customer payments, holding inventory), mark-to-market ensures their financial statements accurately represent the value of those holdings to investors, creditors, and regulators.

Risks and Considerations

Earnings Volatility

The most immediate consequence of mark-to-market is increased earnings volatility. Crypto prices can swing 10-20% or more within a single quarter. Under fair value accounting, those swings flow directly into net income, creating quarter-to-quarter fluctuations that have nothing to do with the company's operating performance. Companies with large crypto holdings relative to revenue may see their earnings dominated by unrealized gains and losses rather than core business results.

Fair Value Challenges for Illiquid Tokens

Not all crypto assets trade on deep, liquid markets. For tokens with low daily volume, thin order books, or limited exchange listings, determining fair value becomes subjective. Companies may need to rely on Level 3 inputs under the ASC 820 hierarchy, requiring significant judgment and increasing audit complexity. The valuation methodology must be documented, defensible, and applied consistently.

Scope Limitations

ASU 2023-08 only applies to crypto assets meeting specific criteria: fungible, cryptographically secured, on a distributed ledger, and not issued by the reporting entity. This excludes several important asset categories:

• Non-fungible tokens (NFTs), which fail the fungibility test
• Wrapped tokens, whose treatment depends on the holder's enforceable rights over the underlying asset
• Tokens issued by the reporting entity or its affiliates
• Tokens providing enforceable rights to goods, services, or other assets

Assets outside the scope of ASU 2023-08 remain subject to other GAAP standards, which may still require impairment-based or cost-based measurement.

IFRS Divergence

International Financial Reporting Standards have not yet adopted a crypto-specific fair value standard. Under IAS 38, crypto assets are generally treated as intangible assets measured at cost, or at a revalued amount where an active market exists. The IASB has the topic on its active work plan, but as of late 2025, no equivalent to ASU 2023-08 has been finalized. This divergence means multinational companies may need to maintain dual accounting treatments for their crypto holdings depending on the reporting framework.

Tax Implications

Mark-to-market accounting for financial reporting purposes does not automatically change tax treatment. In the U.S., crypto is treated as property for tax purposes, and taxable events generally occur only upon disposition. Companies must manage the difference between book (fair value) and tax (cost basis) treatment, creating temporary differences that affect deferred tax calculations.
