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. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been omitted. All significant intercompany accounts and transactions have been eliminated in consolidated financial statements. The consolidated balance sheet as of December 31, 2024 has been derived from audited financial statements included in our 2024 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 2024 Form 10-K. Operating results for the three and nine months ended September 30, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025.
Reclassification	In certain instances, amounts reported in prior period consolidated financial statements and accompanying notes may be reclassified to conform to the current presentation. At September 30, 2025, we elected to reclassify certain securities from investment securities available-for-sale to accrued interest receivable and other assets. This reclassification is reflected on the consolidated balance sheet as of December 31, 2024 and within the tables as of as of December 31, 2024 in Note 2 – Investment Securities, Note 7 – Fair Value of Financial Instruments and Note 8 – Fair Value Measurements. For the three and nine months ended September 30, 2025 and 2024, we elected to reclassify the balance of software costs to a separate line item included in noninterest expenses titled software costs. These costs were previously included in the line item included in noninterest expenses titled travel, entertainment, dues and subscriptions.
Subsequent Events	We have evaluated subsequent events for potential recognition and/or disclosure through the date these consolidated financial statements were issued.
Recently Issued Accounting Pronouncements and Recently Adopted Accounting Pronouncements	Recently Issued Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments require disaggregated information about a reporting entity's effective tax rate reconciliation, as well as information on income taxes paid. Public business entities will be required to disclose additional information in specified categories with respect to the reconciliation of the effective tax rate to the statutory rate for federal, state and foreign income taxes. The amendments also require greater detail about individual reconciling items in the rate reconciliation to the extent that the impact of those items exceeds a specified threshold. The amendments are effective for annual reporting periods beginning after December 15, 2024. We are preparing to adopt the disclosure requirements included in this ASU and we do not believe that the amendments will have a material impact to our consolidated financial statements. We believe the impact of the amendments in this ASU will be isolated to our footnote disclosure regarding Income Taxes. In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40). The amendments improve the disclosures about a public business entity’s expenses and address requests from investors for more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation, amortization and depletion) in commonly presented expense captions (such as cost of sales and research and development). The amendments are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. We are currently evaluating the impact these changes may have on our consolidated financial statements. In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40). The amendments improve the disclosures about software costs that are accounted for under Subtopic 350-40, Intangibles - Goodwill and Other - Internal-Use Software. The amendments are effective for all entities for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. We are currently evaluating the impact these changes may have on our consolidated financial statements. Recently Adopted Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segments Disclosures. The amendments are intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. In addition, the amendments clarify circumstances in which an entity can disclose multiple segment measures of profit or loss and provide new segment disclosure requirements for entities with a single reportable segment. The amendments are effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024.
