BCL S 1.4 Reporting: Luxembourg’s Monthly Valuation Effects Return

BCL S 1.4 reporting is the monthly return in which every resident credit institution in Luxembourg tells the Banque centrale du Luxembourg (BCL) how much of the movement in its statistical balance sheet came from write-offs and revaluations. Layout 3 of report S 1.4, “Valuation effects on the statistical balance sheet of credit institutions”, has been mandatory since the January 2022 reference period, and each monthly file is due 10 working days after month-end, the same day as the S 1.1 monthly balance sheet.

The ECB uses these figures to turn month-end stocks into financial transactions for euro area monetary statistics. The BCL instructions show what happens without them: in their worked example a EUR 25,000 write-off, if left out of S 1.4, makes net new lending look EUR 25,000 smaller than it was, because the whole change in the loan stock is treated as a transaction.

The report is short next to S 1.1, but its rules are spread across five Layout 3 documents, two general BCL documents and Part 4 of Annex I to ECB Regulation (EU) 2021/379, and those sources do not agree on every line code.

Legal basis for BCL S 1.4 reporting: revaluation adjustments under ECB Regulation 2021/379

The obligation comes from Regulation (EU) 2021/379 of the European Central Bank of 22 January 2021 on the balance sheet items of credit institutions and of the monetary financial institutions sector (recast), ECB/2021/2, known as the BSI Regulation. Article 5(1)(b) requires monetary financial institutions (MFIs) to report the monthly revaluation adjustments specified as minimum requirements in Table 1A in Part 4 of Annex I, plus the other monthly revaluation adjustments in that table where the national central bank requires them. Article 5(2)(b) applies the same requirement to non-MFI credit institutions, with two exceptions: notional cash pool positions and MMF shares or units issued.

Part 4 of Annex I explains the purpose. Revaluation adjustments allow the ECB to calculate financial transactions by showing the impact of changes in prices or other valuations on end-period outstanding amounts. Loan revaluations cover write-downs, the write-off of a loan’s full outstanding amount and reversals of either, as well as the gap between the outstanding amount and the sale price when a loan is disposed of with derecognition. Changes caused by exchange rate movements on positions not denominated in euro are left out; exchange rate adjustments for compiling transactions are derived separately.

Article 18 sets the timing: the Regulation applied from 26 June 2021, while Articles 5, 8 and 9, the reporting requirements, accounting rules and derogations, applied from 1 February 2022. Article 7(1) leaves frequency and timeliness of collection to each national central bank, which must inform its reporting agents.

The BCL implemented the recast through Circular BCL 2021/244 of 10 February 2021, which lists S 1.4 among the reports updated for the Regulation’s new headings and country codes and made the new collection mandatory from the January 2022 reporting period. The S 1.4 instructions themselves cite no article of the Regulation. They explain that the BCL estimates transactions in debt securities held (1-003000), equity (1-005000), short sales (2-002050) and debt securities issued (2-003000) from security-by-security reporting, so those four lines are absent from S 1.4. Article 5(3) of the Regulation lets central banks collect securities data security by security, and Article 9(6)(c) allows a derogation from the revaluation adjustment requirement where the agent reports end-month securities amounts security by security with each security’s carrying value. The instructions cite neither provision.

The document set for Layout 3 is the instructions, the report template, a compendium of verification rules, its annex workbook and an XML schema package. Two general BCL documents apply alongside them: “Definitions and concepts for the statistical reporting of credit institutions” (July 2024) and the “Manual of electronic transmission” (February 2021). Where the French and English versions differ, the French text prevails.

Who must report S 1.4: resident credit institutions, with no activity trigger

Section 1.1 of the instructions is one sentence: report S 1.4 must be provided by all resident credit institutions regardless of their legal status. That is the same population as S 1.1 and matches Article 3(1) of Regulation 2021/379, under which the actual reporting population consists of MFIs and non-MFI credit institutions resident in the euro area. Luxembourg branches of banks incorporated elsewhere are inside it.

The scope sentence has no activity condition. The BCL’s securitisation report S 1.8 is owed only by institutions that carried out securitisations or other loan transfers in the form of disposals or acquisitions; S 1.4 carries no equivalent “if” clause, so a bank with a quiet month remains a reporting agent. Whether a month without any valuation effect still needs a file is a separate question, covered under submission below.

The BCL’s Definitions document sets the accounting versions. Luxembourg-law banks without foreign branches, and Luxembourg branches of foreign-law banks, report a single version L. Luxembourg-law banks with foreign branches provide “some” statistical reports in two versions, L for the Luxembourg head office and N for the whole entity, in line with FINREP template F 31. The transmission manual gives S 1.4 a single file name, S0104_L3, with no L or N suffix of the kind the quarterly balance sheet S 2.5 carries. The S 1.4 documents do not state the perimeter in a sentence; my reading, consistent with the residency basis of the Regulation, is the resident Luxembourg business, the same perimeter as S 1.1.

The instructions contain no size threshold and mention no derogation. The Regulation lets national central banks grant several derogations, each of which depends on a decision by the central bank.

Under Article 9(1), they may exempt small MFIs from Article 5(1) if the combined contribution of the exempted MFIs stays within 5% of the national MFI balance sheet total, subject to the further conditions in that paragraph. Under Article 9(2) and Part 6 of Annex I, small credit institutions may be allowed to report Parts 2, 4 and 5, which include the revaluation adjustments, quarterly, if the combined contribution of all such institutions stays within 10% of the national and 1% of the euro area MFI balance sheet. For non-MFI credit institutions, Article 9(5)(a) allows a derogation from Article 5(2) where total assets are EUR 350 million or less. Article 9(6) lets central banks allow MFIs and non-MFI credit institutions alike to report securities revaluation adjustments quarterly instead of monthly (point (b)), or to be exempted from the revaluation adjustment requirement where they report securities security by security (point (c)). Nothing in the published S 1.4 documents applies any of these routes, so the default for a resident credit institution is a monthly file.

The file header separates two roles. The declarant is the entity whose data are reported, the reporter the entity that submits the file, each identified by type and CSSF number: type 23, letter B in the file name, for banks, and type 32, letter P, for professionals of the financial sector. A PSF can therefore send S 1.4 for a bank, which remains the declarant.

What the report contains: loan write-offs and price effects, line by line

S 1.4 carries the valuation effects contained in the change between two month-end balance sheets. The instructions stress the distinction: the BCL already computes the change in outstanding amounts from S 1.1, and what it cannot see is how much of that change came from something other than transactions. The return holds two families of adjustment:

• Write-downs and write-offs on the loan items listed in section 3.1 of the instructions, from 1-002000 Loans down to the detail lines for consumer credit, house purchase, revolving and card credit, affiliated entities, reverse repos, syndicated loans and notional cash pools.
• Valuation effects on the items listed in section 3.2: non-financial assets, financial derivatives on both sides, remaining assets and liabilities, and the capital, provisions, value adjustments and results lines.

The worked example in the instructions sets the logic. A bank reports loans of EUR 1,000,000 at the end of February 2014. In March it books a EUR 50,000 value adjustment on a struggling borrower, loses EUR 25,000 on a bankrupt customer, receives EUR 75,000 of repayments and grants EUR 500,000 of new loans. S 1.1 shows EUR 1,400,000, a change of EUR 400,000. S 1.4 reports minus EUR 25,000, and the BCL derives net transactions of EUR 425,000.

The EUR 50,000 value adjustment produces no S 1.4 entry on the loan lines. Loans sit in the statistical balance sheet at gross nominal value, the principal the debtor is contractually obliged to repay, with provisions under 2-008000 and value adjustments under 2-009000. Article 8(2) of Regulation 2021/379 sets the same rule and excludes write-offs and write-downs from the reported principal. An adjustment is reported only when the loan itself is written down or off, and the write-down counts whether or not a value adjustment had been booked earlier.

A timing test sits in section 3. Valuation effects are reported only for positions on the statistical balance sheet at both the end of the preceding month and the end of the reference month. Positions bought and sold within the month, and positions sold during the month, are left out. The instructions carve one exception into the loan section: write-offs or write-downs recognised when a loan is sold or transferred to a third party are included, where identifiable.

Each amount sits on a line identifier built from item, country, currency and sector, plus an initial-maturity code. In 1-002000-LU-EUR-22000 with maturity code I05A-999, the item is loans, the counterparty is resident in Luxembourg, the currency is EUR, the sector is households and non-profit institutions serving households, and the original maturity is over five years. Country groups use the ISO code LU and the BCL’s aggregation codes X3, for the other Monetary Union member states, and X4, for the rest of the world. Currencies split into EUR and XX2, all other currencies, and lines without a breakdown use XX, XXX, 90000 and I999-999.

Maturity follows the template and the verification annex. Loans use four initial-maturity bands, codes I000-01A, I01A-02A, I02A-05A and I05A-999. Revolving, card and cash pool lines, all non-loan assets and every liability line go in the no-breakdown column only; the liabilities sheet prints five maturity columns, and the annex requires all of them to stay at zero.

Household loans need a purpose split. Section 4.1 of the instructions requires write-downs on loans to households in sector 22000 to be broken down across credit for consumption, lending for house purchase and other loans, and states that revolving loans, overdrafts and card credit are included in the consumption line, respecting the country and currency split.

The sign rule is in section 3.2: a net increase following a revaluation is reported with a positive sign, a net decrease with a negative sign, which is why the bankrupt customer in the example becomes minus EUR 25,000. Amounts are expressed in the institution’s accounting currency with up to five decimals under section 2.3 of the Definitions document. Valuation of everything outside loans and deposits follows the prudential reporting rules, so the price effect on a derivative or a building is the change in the value at which supervisory reporting carries it. The S 1.4 documents set no rounding rule of their own.

S 1.4 deadlines: the tenth ECB working day, shared with S 1.1

The instructions require S 1.4 monthly, no later than 10 working days after the end of the reference period. Section 2.2 of the Definitions document sets the reference date, in principle, as the last day of each month. The BCL publishes a calendar of remittance dates each year, and its footnote ties the count to the working days the ECB defines for national central banks’ statistical transmissions. The calendar is therefore the reference for each date, ahead of any local holiday count.

The month now closing is due on the tenth ECB working day of the next month. The 2026 calendar, issued in December 2025, sets these S 1.4 L3 dates:

Every one of those dates is also the S 1.1, S 1.8, S 1.9, S 1.12-L and TPTBBL date; in the same monthly table, S 1.5, the interest rate report, falls a few days later. Since S 1.4 describes the move between the same two month-ends that S 1.1 reports, the write-off and revaluation figures and the stocks they explain come out of one close.

The deadline exists to protect the BCL’s own. Article 7(2) of Regulation 2021/379 gives national central banks until close of business on the 15th working day after month-end to send monthly statistics to the ECB, and Circular 2021/244 reminds banks of that window when it asks them to respect the BCL’s deadlines scrupulously. The CSSF’s prudential cycle runs separately, as our CSSF reporting calendar for Q3 2026 shows. Under section 2.5 of the Definitions document, reporting agents keep monthly statistical reports and related documents for 24 months, which covers the working papers behind each write-off total.

Submission of the S0104_L3 XML file through Sofie or e-file

S 1.4 travels as an XML file built to the BCL’s schema package, which unpacks to a folder named S0104_Schema_XML_v1_1_r144 holding datatypes.xsd, structures.xsd, the main schema S14.xsd, documentation and two example files. The root element is S14 in the namespace http://www.bcl.lu/2009/S1.4, with a version attribute fixed at 1.1 and a required creationDateTime.

The header carries six elements in order: endMonthDate, closingDate, reporterID and declarantID (each a type and a code), reportingCurrency and layout. The content holds two optional blocks, assets and liabilities, each a sequence of reportedLine elements. A reportedLine has an id with five fields, item, country, currency, sector and initialMaturity, and a reportedAmount defined as a decimal with up to five fraction digits.

Asset items must match the pattern 1- plus six characters and liability items 2- plus six. Each block declares a uniqueness constraint over the five id fields, so a duplicated line fails the schema. There is no off-balance-sheet block.

The transmission manual sets the file name: S0104_L3_yyyymm_Rrrrrrrrrr_Dddddddddd_yyyymmdd_nnn, giving the reference year and month, the reporter’s type letter and nine-digit CSSF number, the declarant’s, the file’s creation date and a sequence number. Numbers are left-padded with zeros, and the sequence restarts at 001 each day; 000 is never used. The package’s Layout 3 example, S0104_L3_202201_B000000999_B000000999_20220210_001.xml, is a January 2022 report from bank 999 about itself, created on 10 February 2022, with layout 3 and EUR as reporting currency in the header.

The example files show structure only. In the Layout 3 example, results 2-010000 carries country LU and liability derivatives 2-011000 carry XX, while the template codes the first XX and the second by LU, X3 and X4. Line combinations should come from the template and the verification annex.

Two channels are named, Sofie and e-file, and the manual adds that the BCL will accept any new secure channel both sides agree on. E-mail is closed: circular letter ST.24-0013 of 15 January 2024 told reporters the BCL no longer accepts statistical reports by e-mail.

Two points are left open. The S 1.4 documents do not say whether a month with no valuation effect at all still needs a file; the schema accepts a content element with neither block, and the BCL calendar lists an S 1.4 date for every month, so the safe course is to confirm the BCL’s expectation once and record it. Nor do they describe a resubmission procedure. The sequence number separates files created the same day, and Annex IV of the Regulation requires agents to follow the BCL’s revisions policy and to explain revisions that deviate from regular revisions.

Validation: zero cells, one household hierarchy and what the rules leave unchecked

The S 1.4 compendium of verification rules (February 2021) says the report has, for the time being, only permanent rules, which the BCL invites software providers to implement. Its one global rule reads: all the lines may have a debit or a credit trend. Positive and negative amounts are both legitimate on every line, which fits a report where a write-off is negative and a revaluation gain positive.

The detail sits in the annex workbook, dated 17 November 2021 on the BCL page, with one identifier per rule:

• Assets – 1: 649 cells in the Assets and Assets – Details sheets that must contain zero. Rule S0104_L3_A1_0001, for instance, sets 1-002000-LU-EUR-11000-I999-999 to zero, so a loan write-down cannot sit in the no-breakdown column; other rules zero maturity-band cells on lines reported without breakdown, such as notional cash pools, revolving loans and the non-loan assets.
• Assets – 2: 24 complex hierarchy rules, S0104_L3_A2_0001 to 0024, requiring household loans in sector 22000 to equal the sum of consumption, house purchase and other loans for each country group, currency and maturity band.
• Liabilities – 1: 95 rules, S0104_L3_P1_0001 to 0095, zeroing every maturity band on the liability lines.

The published rules stop there. The S 1.1 compendium has a section of checks against the security-by-security report TPTBBL; the S 1.4 compendium has no cross-report rule, so nothing in it compares a reported write-off with the movement in S 1.1 loan stocks. The schema is equally permissive on codes: any six-character item code passes the pattern, and the transmission manual warns that a code can satisfy the format and still be invalid under the nomenclature. A mistyped item code reaches the BCL unchallenged by the XSD.

Behind the rule book stand the Annex IV minimum standards, which Article 10(1) of Regulation 2021/379 imposes for transmission, accuracy, compliance with concepts and revisions. One accuracy standard fits S 1.4 closely: reporting agents must be able to provide information on the developments implied by the transmitted data, which for this report means explaining why a stock moved without a transaction.

Since 30 April 2024 those standards have been enforced through Regulation (EU) 2022/1917 (ECB/2022/31) on infringement procedures, which repealed Decision ECB/2010/10. Circular letter ST.24-0013 explains that, from the April 2024 reference period, the ECB and the BCL record alleged infringements detected during each production month, that the ECB may impose sanctions after an infringement procedure, and that systematic or intentional failure to report on time, correctly, completely or in the prescribed form counts as serious misconduct. Outside serious misconduct, a reporting agent warned of accumulated alleged infringements may submit a remedial plan.

The BCL’s April 2025 feedback document, which names S0104 among the collections covered, announces three feedback types to be put in place: FL-OK or FL-NOK on whether the file has technical errors, DQ-FDB for data points the BCL needs corrected or confirmed, and ADHC-FDB for requests outside the normal cycle. Feedback files start with FDBBUSI and carry the name of the file answered. Delivery is moving from e-mail to Sofie and e-file in stages, aligned with the process known from BCL AnaCredit reporting, and each feedback states its own response deadline, which the document places inside the ECB non-compliance framework.

Caveats: where the Layout 3 documents disagree, exchange rates and loan sales

The instructions are dated February 2021 and were last updated on 8 March 2021; the template was updated on 18 August 2021 and the annex on 17 November 2021. The later files do not always match the instructions:

The 1-099999 code is the one a schema will not catch, for the reason given in the validation section. Where the documents conflict, the combination to use is a question for the BCL; the French text governs any language difference, but these gaps sit between documents.

Exchange rates are the second caveat. Part 4 of the Regulation keeps exchange rate effects out of reported revaluation adjustments, and section 2.1 of the instructions says the ECB compiles valuation effects from exchange rate changes, in principle and to the extent possible. The S 1.4 documents never say in terms that a foreign-currency translation gain is excluded; my reading of the two texts together is that an S 1.4 amount should carry price and write-off effects and no translation effect.

Loan sales are the third. The Regulation’s Part 4 counts the difference between the outstanding amount and the sale price on a derecognised disposal as a revaluation, and a purchase below the outstanding amount as a positive one. S 1.4 picks up write-downs recognised at sale where identifiable, but its two-month-end test leaves out positions bought during the month, and the instructions do not mention purchases at a discount. Transferred loans also appear in S 1.8, whose instructions require outstanding amounts and valuation effects for the loans covered by its two stock sub-tables, ETIB and ETSB. A bank with an active loan-sale programme can find the same loan in both reports, and the documents do not say how the two interact.

Two smaller points. The instructions list 2-009000 value adjustments among the valuation-effect lines without saying which movements in it count; the worked example only establishes that a new value adjustment creates nothing on the loan lines. And section 2.1 refers to “section 3.1” for derivatives and non-financial assets, whose list is in section 3.2.

Counterparty classification drives the country and sector splits. The BCL’s July 2025 euro adoption circular letter tells banks to identify counterparties using the CSSF’s official list of credit institutions and the ECB’s list of MFIs. Germany works from the same BSI Regulation with its own scheme, described in our article on the Bundesbank customer classification for MFI statistics. On valuation, a bank whose FINREP reporting already measures derivatives and real estate can take the price effects from the same ledger, since the S 1.4 instructions point to prudential valuation for every line outside loans and deposits.

Changes to S 1.4: from Layout 2 to Bulgaria and IReF

The revision-marked Layout 3 instructions show what moved from Layout 2. “Claims” became “Loans” throughout. The investment and operating-purpose loan items 1-002030 and 1-002040 were deleted, together with the purpose split for non-financial corporations. Notional cash pool positions, 1-NC2000, joined the loan list. And household revolving and card credit, previously split by the customer’s use of the loan, is now included in credit for consumption.

Circular 2021/244 describes the same direction for the whole collection: new items for notional cash pools, non-financial real estate, equity raised, income and expenses recognised in equity and profit or loss for the year, simpler revolving and card credit items, and the end of the investment and operating loan items. The circular offered a test phase from September 2021.

The Bulgaria letter changed S 1.4 directly. After the EU Council approved Bulgaria’s accession on 8 July 2025, the other Monetary Union member states category includes Bulgaria from 1 January 2026; until 31 December 2025 Bulgaria sat in the rest of the world. The new classification applies first to reports for January 2026, and the letter names S 1.4 among the monthly reports affected.

The longer horizon is the ECB’s Integrated Reporting Framework (IReF). On 8 June 2026 the ECB announced a public consultation on the draft IReF Regulation in the second half of 2027, a one-year pilot phase from the second quarter of 2030, and first official reporting in the second quarter of 2031, with an initial one-year parallel phase in which existing statistical reporting within IReF’s scope continues. The timelines depend on adoption of the IReF Regulation. The ECB’s April 2024 IReF overview lists the BSI Regulation among the regulations in scope, for MFIs and non-MFI credit institutions. Neither the ECB announcement nor the BCL’s IReF page names S 1.4 or gives it an end date; the BCL says a plan for how national collection frameworks will evolve is being prepared.

Frequently Asked Questions

Does reversing an earlier write-down produce a positive S 1.4 amount?

Part 4 of Annex I to Regulation 2021/379 includes reversals of write-downs and write-offs in loan revaluations, and the S 1.4 sign rule records a net increase with a positive sign. The S 1.4 instructions do not mention reversals in terms, so the Regulation is the anchor; the two-month-end test still applies, so the loan has to be on the balance sheet at both month-ends.

A write-down on a loan to a Bulgarian company in December 2025 is corrected after January 2026. X3 or X4?

Circular letter ST.25-0366 says S 1.4, together with S 1.1, S 1.5, S 1.8 and S 2.5, must be established treating Bulgaria as outside the Monetary Union up to and including 31 December 2025. On that wording, a corrected December 2025 file keeps the Bulgarian borrower in X4.

Is a write-down on a syndicated loan reported once or twice?

On the template’s structure, it appears on a main line and on a detail line. Section 4 of the instructions describes the cells of the asset details sub-table as additional information on lines in the main Assets sub-table, so the amount sits in 1-002000 under the borrower’s country, currency and sector, and again in 1-S02000, which the template breaks down only by country group, a broad sector and maturity.

Our accounting currency is USD. Is S 1.4 reported in euro?

Section 2.3 of the Definitions document requires statistical reports in the institution’s accounting currency, and the XML header carries the reporting currency. The EUR and XX2 split in the template refers to the denomination of the position written down, so a euro loan is coded EUR whatever the reporting currency.

Are write-downs on loans to sole proprietors shown separately?

Only within other household loans. The template adds an “of which” line with sector code 22110, labelled households, sole proprietors, under 1-002999 for each country group and currency. Write-downs on consumer credit or house purchase loans to sole proprietors stay in their purpose lines without that flag.

Do reverse repos with banks need a separate detail line?

The detail line 1-P02000 exists only for central counterparties, sector 42200, in each country group. A write-down on a reverse repo with any other counterparty appears in the main 1-002000 line under that counterparty’s sector, with no separate repo flag.

Key Takeaways

• Feed S 1.4 from the month’s write-off journal and revaluation postings, keyed to the counterparty, currency and initial-maturity attributes already used for the S 1.1 loan lines.
• Flag loans sold or bought during the month in the source data, so the two-month-end filter and the write-down-at-sale exception run mechanically.
• Keep foreign-exchange translation out of revaluation postings on derivatives, real estate and remaining items: Part 4 of the Regulation excludes exchange rate effects, although the BCL documents never say so for S 1.4 in terms.
• Add an item-code whitelist built from the annex and the Definitions document, since the XSD accepts any six-character code.
• Write to the BCL once on nil months and on the 1-099999 versus 1-090999 code, and keep the reply with the report records.
• Where the bank sells or securitises loans, decide which events feed S 1.8 and which feed S 1.4 before the first month of activity; the BCL documents do not draw that line.
• Put the IReF consultation planned for the second half of 2027 on the watch list; the BSI Regulation behind S 1.4 is within its scope.

Preparing the next S 1.4 valuation file

For the month now closing, the deliverable is an S0104_L3 XML file sent through Sofie or e-file by the date in the BCL’s remittance calendar, the tenth ECB working day of next month and the same day as S 1.1. The write-off listing and revaluation workings behind each line go into the report file kept for 24 months.
