Accounting Policies [Abstract]
Nature of Operations and Basis of Presentation	Nature of Operations OFG is a publicly-owned financial holding company incorporated under the laws of the Commonwealth of Puerto Rico. OFG operates through various subsidiaries including, a commercial bank, Oriental Bank (the “Bank”), a securities broker-dealer and investment adviser, Oriental Financial Services LLC (“Oriental Financial Services”), an insurance agency, Oriental Insurance, LLC (“Oriental Insurance”), a captive reinsurance company organized under the laws of the Cayman Islands, OFG Reinsurance Ltd (“OFG Reinsurance”), and a retirement plan administrator, Oriental Pension Consultants, Inc. (“OPC”), and OFG Ventures LLC (“OFG Ventures”), which holds investments. Through these subsidiaries and their respective divisions, OFG provides a wide range of banking and financial services such as commercial, consumer and mortgage lending, leasing, auto loans, financial planning, insurance sales, money management and investment banking and brokerage services, as well as corporate and individual trust services. Basis of Presentation The accompanying unaudited consolidated financial statements of OFG have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with guidance provided by the Securities and Exchange Commission. Accordingly, these consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. In the opinion of management, the accompanying unaudited consolidated financial statements reflect all adjustments considered necessary for a fair presentation of the financial position, results of operations and cash flows of OFG on a consolidated basis, and all such adjustments are of a normal recurring nature. The consolidated financial statements should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021. Operating results for three months ended March 31, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. The Company evaluated subsequent events through the filing date of its quarterly report on Form 10-Q with the SEC and has recorded or disclosed those material events or transactions as described within the accompanying consolidated financial statements and notes.
New Accounting Updates Adopted in 2022 and New Accounting Updates Not Yet Adopted	New Accounting Updates Adopted in 2022 Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. In August 2020, the FASB issued ASU 2020-06 to clarify the accounting for certain financial instruments with characteristics of liabilities and equity. The amendments in this update reduce the number of accounting models for convertible debt instruments and convertible preferred stock by removing the cash conversion model and the beneficial conversion feature model. Limiting the accounting models will result in fewer embedded conversion features being separately recognized from the host contract. Convertible instruments that continue to be subject to separation models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in-capital. In addition, this ASU improves disclosure requirements for convertible instruments and earnings-per-share guidance. The ASU also revises the derivative scope exception guidance to reduce form-over-substance-based accounting conclusions driven by remote contingent events. The amendments in this update are effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. Our adoption of this standard did not have a material impact on our financial statements. Lessors—Certain Leases with Variable Lease Payments. FASB ASC 842 – In July 2021, the FASB issued ASU 2021-05 to amend the lease classification requirements for lessors to align them with practice under ASC Topic 840. Lessors should classify and account for a lease with variable lease payments that do not depend on a reference index or a rate as an operating lease if both of the following criteria are met: (1) The lease would have been classified as a sales-type lease or a direct financing lease in accordance with the classification criteria in ASC paragraphs 842-10-25-2 through 25-3; and (2) The lessor would have otherwise recognized a day-one loss. When a lease is classified as operating, the lessor does not recognize a net investment in the lease, does not derecognize the underlying asset, and, therefore, does not recognize a selling profit or loss. The amendments in this update are effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. Our adoption of this standard did not have a material impact on our financial statements. New Accounting Updated Not Yet Adopted Derivatives and Hedging (Topic 815) Fair Value Hedging—Portfolio Layer Method. In March 2022, the FASB issued ASU 2022-01 to allow non-prepayable financial assets also to be included in a closed portfolio hedged using the portfolio layer method. That expanded scope permits an entity to apply the same portfolio hedging method to both prepayable and non-prepayable financial assets, thereby allowing consistent accounting for similar hedge. The amendments in this update are effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. Early adoption is permitted on any date on or after the issuance of this ASU for any entity that has adopted the amendments in ASU 2017-12 for the corresponding period. If an entity adopts the amendments in an interim period, the effect of adopting the amendments related to basis adjustments should be reflected as of the beginning of the fiscal year of adoption. OFG will adopt this guidance when it becomes effective and the impact on our financial statements is not expected to be material. Financial Instruments—Credit Losses Troubled Debt Restructurings and Vintage Disclosures. In March 2022, the FASB issued ASU 2022-02 to address the accounting guidance on troubled debt restructurings (TDRs) for creditors in ASC 310-402 and amend the guidance on vintage disclosures to require disclosure of current-period gross write-offs by year of origination. The ASU also updates the requirements related to accounting for credit losses under ASC 326 and adds enhanced disclosures for creditors with respect to loan refinancing and restructurings for borrowers experiencing financial difficulty. The amendments in this update are effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. Entities are permitted to early adopt these amendments, including adoption in any interim period, provided that the amendments are adopted as of the beginning of the annual reporting period that includes the interim period of adoption. In addition, entities are permitted to elect to early adopt the amendments related to TDR accounting and related disclosure enhancements separately from the amendments related to the vintage disclosures. OFG is currently evaluating the impact on the consolidated financial statements upon adoption of this standard.
