Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation HBT Financial, Inc. (“HBT Financial” or the “Company”) is headquartered in Bloomington, Illinois and is the holding company for Heartland Bank and Trust Company (“Heartland Bank” or the “Bank”). The Bank provides a comprehensive suite of financial products and services to consumers, businesses, and municipal entities throughout Illinois and eastern Iowa. Additionally, the Company is subject to the regulations of certain federal and state agencies and undergoes periodic examinations by those regulatory agencies. The unaudited consolidated financial statements, including the notes thereto, have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) interim reporting requirements. Certain information in footnote disclosures normally included in financial statements prepared in accordance with GAAP has been condensed or omitted pursuant to rules and regulations of the SEC. These interim unaudited consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on March 7, 2025. The unaudited consolidated financial statements include all normal, recurring adjustments necessary for a fair presentation of the results for the interim periods. The results for interim periods are not necessarily indicative of results for a full year.
Use of Estimates	Use of Estimates The accompanying consolidated financial statements have been prepared in conformity with GAAP. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and the reported results of operations for the periods then ended. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant changes in the near term relate to the determination of the allowance for credit losses.
Reclassifications	Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation without any impact on the reported amounts of net income or stockholders’ equity.
Subsequent Events	Subsequent Events In preparing these consolidated financial statements, the Company has evaluated events and transactions for potential recognition or disclosure through the date the financial statements were issued.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In December 2023, the FASB issued Accounting Standards Update ("ASU") 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 expands income tax disclosure requirements. The amendments require annual disclosure of certain information relating to the rate reconciliation, income taxes paid by jurisdiction, income (loss) from continuing operations before income tax expense (benefit) disaggregated between domestic and foreign, income tax expense (benefit) from continuing operations disaggregated by federal (national), state, and foreign. The amendments also eliminate certain requirements relating to unrecognized tax benefits and certain deferred tax disclosure relating to subsidiaries and corporate joint ventures. The amendments in this update are effective for years beginning after December 15, 2024. ASU 2023-09 should be applied on a prospective basis, but retrospective application is permitted. Early adoption is permitted. This standard did not have a material impact on the Company’s consolidated results of operations or financial position. In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. ASU 2024-03 provides more decision-useful information about a public entity's expenses by requiring additional detail on expenses reported in income statements. Under the ASU, public entities will provide detailed disclosure in interim and annual periods of specified categories underlying certain expense captions. The ASU requires public entities to apply the amendments prospectively, with an option to use retrospective application. The amendments in this update are effective for years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. This standard is not expected to have a material impact on the Company's consolidated results of operations or financial position.
FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1 - Quoted prices (unadjusted) for identical assets or liabilities in active markets that the Company has the ability to access as of the measurement date. Level 2 - Significant observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 - Significant unobservable inputs that reflect a Company’s own assumptions about the assumptions that market participants would use in pricing as asset or liability. The Company uses fair value to measure certain assets and liabilities on a recurring basis, such as investment securities, mortgage servicing rights, and derivatives. For assets measured at the lower of cost or fair value, the fair value measurement criteria may or may not be met during a reporting period, and such measurements are therefore considered "nonrecurring" for purposes of disclosing the Company's fair value measurements. Fair value is used on a nonrecurring basis to adjust carrying values for loans held for sale, collateral-dependent loans, bank premises held for sale, and foreclosed assets. Recurring Basis The following is a description of the methods and significant assumptions used to measure the fair value of assets and liabilities on a recurring basis. Investment Securities When available, the Company uses quoted market prices to determine the fair value of securities; such items are classified in Level 1 of the fair value hierarchy. For the Company’s securities where quoted prices are not available for identical securities in an active market, the Company determines fair value utilizing vendors who apply matrix pricing for similar bonds where no price is observable or may compile prices from various sources. These models are primarily industry-standard models that consider various assumptions, including time value, yield curve, volatility factors, prepayment speeds, default rates, loss severity, current market and contractual prices for the underlying financial instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace. Fair values from these models are verified, where possible, against quoted market prices for recent trading activity of assets with similar characteristics to the security being valued. Such methods are generally classified as Level 2; however, when prices from independent sources vary, cannot be obtained or cannot be corroborated, a security is generally classified as Level 3. The change in fair value of debt securities available-for-sale is recorded through an adjustment to the consolidated statement of comprehensive income. The change in fair value of equity securities with readily determinable fair values is recorded through an adjustment to the consolidated statement of income. Mortgage Servicing Rights The Company has elected to record its mortgage servicing rights at fair value. Mortgage servicing rights do not trade in an active market with readily observable prices. Accordingly, the Company determines the fair value of mortgage servicing rights by estimating the fair value of the future cash flows associated with the mortgage loans being serviced as calculated by an independent third party. Key economic assumptions used in measuring the fair value of mortgage servicing rights include, but are not limited to, prepayment speeds and discount rates. Due to the nature of the valuation inputs, mortgage servicing rights are classified as Level 3. The change in fair value is recorded through an adjustment to the consolidated statement of income. Derivative Financial Instruments Derivative financial instruments are carried at fair value as determined by dealer valuation models. Based on the inputs used, the derivative financial instruments subjected to recurring fair value adjustments are classified as Level 2. For derivative financial instruments designated as hedging instruments, the change in fair value is recorded through an adjustment to the consolidated statement of comprehensive income. For derivative financial instruments not designated as hedging instruments, the change in fair value is recorded through an adjustment to the consolidated statement of income. Loans Held for Sale Mortgage loans originated and held for sale are carried at the lower of cost or estimated fair value. The Company obtains quotes or bids on these loans directly from purchasing financial institutions. Typically, these quotes include a premium on the sale and thus these quotes generally indicate fair value of the held for sale loans is greater than cost. Loans held for sale have been classified as Level 2. Collateral-Dependent Loans Periodically, a collateral-dependent loan is evaluated individually and is reported at the fair value of the underlying collateral, less estimated costs to sell, if repayment is expected solely from the collateral. If the collateral value is not sufficient, a specific reserve is recorded. Collateral values are estimated using recent appraisals and customized discounting criteria. Due to the significance of unobservable inputs, fair values of collateral-dependent loans have been classified as Level 3. Bank Premises Held for Sale Bank premises held for sale are recorded at the lower of cost or fair value, less estimated selling costs, at the date classified as held for sale. Values are estimated using recent appraisals and customized discounting criteria. Due to the significance of unobservable inputs, fair values of collateral-dependent loans have been classified as Level 3. Foreclosed Assets Foreclosed assets are recorded at fair value based on property appraisals, less estimated selling costs, at the date of the transfer. Subsequent to the transfer, foreclosed assets are carried at the lower of cost or fair value, less estimated selling costs. Values are estimated using recent appraisals and customized discounting criteria. Due to the significance of unobservable inputs, fair values of collateral-dependent loans have been classified as Level 3. Cash and Cash Equivalents The carrying amounts of these financial instruments approximate their fair values. Restricted Stock The carrying amount of FHLB stock approximates fair value based on the redemption provisions of the FHLB. Loans The fair value estimation process for the loan portfolio uses an exit price concept and reflects discounts the Company believes are consistent with discounts in the marketplace. Fair values are estimated for portfolios of loans with similar characteristics. Loans are segregated by type such as commercial and industrial, agricultural and farmland, commercial real estate – owner occupied, commercial real estate – non-owner occupied, multi-family, construction and land development, one-to-four family residential, and municipal, consumer, and other. The fair value of loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for similar maturities. The fair value analysis also includes other assumptions to estimate fair value, intended to approximate those a market participant would use in an orderly transaction, with adjustments for discount rates, interest rates, liquidity, and credit spreads, as appropriate. Investments in Unconsolidated Subsidiaries The fair values of the Company’s investments in unconsolidated subsidiaries are presumed to approximate carrying amounts. Time and Brokered Time Deposits Fair values of certificates of deposit with stated maturities have been estimated using the present value of estimated future cash flows discounted at rates currently offered for similar instruments. Time deposits also include public funds time deposits. Securities Sold Under Agreements to Repurchase The fair values of repurchase agreements with variable interest rates are presumed to approximate their recorded carrying amounts. FHLB Advances The fair values of FHLB advances are estimated using discounted cash flow analyses based on current rates offered for borrowings with similar remaining maturities and characteristics. Subordinated Notes The fair values of subordinated notes are estimated using discounted cash flow analyses based on rates observed on recent debt issuances by other financial institutions. Junior Subordinated Debentures The fair values of subordinated debentures are estimated using discounted cash flow analyses based on rates observed on recent debt issuances by other financial institutions. Accrued Interest The carrying amounts of accrued interest approximate fair value.
