Accounting Policies [Abstract]
Principles of Consolidation	The financial statements are consolidated to include the accounts of MVB and its subsidiaries, including the Bank and the Bank’s subsidiaries.
Basis of Presentation	In our opinion, the accompanying consolidated financial statements contain all normal recurring adjustments necessary for a fair presentation of our financial statements for interim periods in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and with instructions for Form 10-Q and Article 10 of Regulation S-X of the SEC. All significant intercompany accounts and transactions have been eliminated in consolidated financial statements. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been omitted. The consolidated balance sheet as of December 31, 2021 has been derived from audited financial statements included in the 2021 Form 10-K. The information presented in this Quarterly Report on Form 10-Q should be read in conjunction with our audited consolidated financial statements and notes thereto included in the 2021 Form 10-K. Operating results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022.
Reclassification	In certain instances, amounts reported in prior periods’ consolidated financial statements have been reclassified to conform to the current presentation.
Subsequent Events	We have evaluated subsequent events for potential recognition and/or disclosure through the date these consolidated financial statements were issued.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and subsequent amendments to the initial guidance in November 2018, ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses, in April 2019, ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments – Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, in May 2019, ASU 2019-05, Financial Instruments – Credit Losses, Topic 326 and in November 2019, ASU 2019-10, Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates and ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments – Credit Losses, all of which clarifies codification and corrects unintended application of the guidance. The new guidance replaces the incurred loss impairment methodology in current U.S. GAAP with an expected credit loss methodology and requires consideration of a broader range of information to determine credit loss estimates. Financial assets measured at amortized cost will be presented at the net amount expected to be collected by using an allowance for credit losses. Purchased credit impaired ("PCI") loans will receive an allowance account at the acquisition date that represents a component of the purchase price allocation. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses, with such allowance limited to the amount by which fair value is below amortized cost. The guidance was initially effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. On November 15, 2019, the FASB issued ASU 2019-10, Financial Investments – Credit Issues (Topic 326), Derivatives and Hedging (Topic 815) and Leases (Topic 842): Effective Dates, which finalizes a delay in the effective date of the standard for smaller reporting companies (“SRCs”). Effective as of the first quarter of 2022, we no longer qualified as an SRC. However, because we met the criteria to be an SRC as of the issuance date of this guidance, we are eligible for the delay in effective date and plan to adopt this standard for fiscal years ending after December 15, 2022. We currently expect to recognize a one-time cumulative effect adjustment to the ALL as of January 1, 2023, but cannot yet determine the magnitude of any such one-time adjustment or the overall impact of the new guidance on the consolidated financial statements. In that regard, we have formed a cross-functional implementation team. This cross-functional team is currently in the process of testing the model and completing the implementation plan, which will include assessment and documentation of processes, internal controls and data sources; model testing and documentation; and system configuration, among other things. We are also in the process of implementing a third-party vendor solution to assist us in the application of this standard. The adoption of this standard could result in an increase in the ALL as a result of changing from an “incurred loss” model, which encompasses allowances for current known and inherent losses within the portfolio, to an “expected loss” model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. Upon adoption of ASU 2016-13, we currently expect to record an increase in our allowance for credit losses of between 15% and 25%, not including any change in unfunded commitment liability; however, the ultimate impact of adoption on our allowance for credit losses could vary significantly from our current estimate as it is influenced by, among other things, the composition, characteristics and quality of our loan portfolio, as well as the prevailing economic conditions and forecasts as of the adoption date. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments provide optional expedients and exceptions for certain contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of rate reform. The guidance is effective from the date of issuance until December 31, 2022. The guidance permits entities to not apply modification accounting or remeasure lease payments in lease contracts if the changes to the contract are related to the discontinuation of the reference rate. If certain criteria are met, the amendments also allow exceptions to the de-designation criteria of the hedging relationship and the assessment of hedge effectiveness during the transition period. In January 2021, ASU 2021-01 was issued by the FASB and clarifies that certain exceptions in reference rate reform apply to derivatives that are affected by the discounting transition. We will continue to assess the impact as the reference rate transition occurs over the next year. As of September 30, 2022, we had loans totaling $437.98 million that reference LIBOR which will be transitioned to the secured overnight financing rate ("SOFR") effective June 30, 2023. In March 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The amendments eliminate the accounting guidance for troubled debt restructurings ("TDRs") in subtopic 310-40, Receivables - Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. Rather than applying the recognition and measurement guidance for TDRs, an entity must apply the loan refinancing and restructuring guidance in paragraphs 310-20-35-9 through 35-11 of the codification to determine whether a modification results in a new loan or a continuation of an existing loan. The amendments also include provisions for disclosure of current-period gross writeoffs by year of origination for financing receivables and net investment in leases within the scope of subtopic 326-20, Financial Instruments - Credit Losses - Measured at Amortized Cost. Gross writeoff information must be included in the vintage disclosures required for public business entities which requires that an entity disclose the amortized cost basis of financing receivables by credit-quality indicator and class of financing receivables by year of origination. This amendment is effective concurrently with the amendments in ASU 2016-13 which is currently effective for fiscal years beginning after December 15, 2022. These amendments primarily impact disclosure requirements and we do not believe they will have a material impact on our consolidated financial statements. In March 2022, the SEC released Staff Accounting Bulletin No. 121 ("SAB 121"), which updates the SEC's position regarding the accounting for obligations to safeguard crypto-assets an entity holds for platform users. When a reporting entity holds crypto-assets for platform users and maintains the cryptographic key information necessary to access the crypto-asset, the reporting entity should present a liability on its balance sheet to reflect its obligation to safeguard the crypto-assets held for platform users. The liability represents the loss exposure due to the risks associated with safeguarding crypto-assets. The entity should also record an asset at the same time that recognizes the fair value of the crypto-assets held for its platform users. SAB 121 is effective no later than the first interim or annual period ending after June 15, 2022, with retrospective application as of the beginning of the fiscal year to which the interim or annual period relates. We do not currently expect this update to impact our consolidated financial statements. In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. The amendments clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security, and therefore, is not considered in measuring fair value. The amendments also clarify that an entity cannot recognize and measure a contractual sale restriction as a separate unit of account and require additional disclosures related to equity securities with contractual sale restrictions. The amendment is effective for fiscal years beginning after December 15, 2023. We do not currently expect these amendments to have a material impact our consolidated financial statements.
