BCL S 1.9 Reporting: Renminbi Loans, Deposits and the CNH Rule

Since the June 2015 reference period, Luxembourg credit institutions that hold and trade renminbi have been required to file report S 1.9, “Information on CNY operations”, with the Banque centrale du Luxembourg (BCL) every month. Circular BCL 2015/238 of 12 January 2015 introduced BCL S 1.9 reporting, and each monthly file is due no later than 10 working days after month-end.

The return exists because of a 2014 agreement between the BCL and the People’s Bank of China (PBoC): the BCL monitors the renminbi market in Luxembourg and shares data with the PBoC. It is a short return, 17 lines on three sheets, and Layout 0, published in January 2015, is still the only layout on the BCL’s S 1.9 page.

The currency code needs particular care. A BCL circular letter of 16 April 2015 told banks that “CNY” in S 1.9 covers every renminbi position, onshore CNY and offshore CNH alike, and at quarter-ends the S 2.5-L verification rules hold each S 1.9 loan and deposit line to that reading.

S 1.9 is a national BCL collection with no ECB regulation behind it. That sets it apart from the collections the BCL lists in circular letter ST.24-0013 by their ECB legal basis, such as Regulation (EU) 2021/379 (ECB/2021/2) on the balance sheet items of credit institutions and of the monetary financial institutions sector. The founding text is Circular BCL 2015/238, “Introduction of a new statistical reporting on renminbi-denominated operations”, dated 12 January 2015 and addressed to all credit institutions.

The circular traces the requirement to two events. On 28 June 2014 the Governors of the BCL and the PBoC signed a Memorandum of Understanding on cooperation in the oversight, information exchange and assessment of the renminbi market. On 16 September 2014 the PBoC designated Industrial and Commercial Bank of China (ICBC), Luxembourg Branch, as renminbi clearing bank in Luxembourg. Under the Memorandum, the BCL monitors the renminbi market in Luxembourg and shares pertinent data with the PBoC.

The circular also explains the design. Some of the information the PBoC asked for was already available to the BCL; the rest was missing, collected at a lower frequency or not detailed enough. The Board of the BCL decided to collect that gap through a dedicated report, citing the small and specific data need and the opinions of the Consultative commission on money and banking statistics. Securities were left out because the monthly security-by-security reporting already carries enough detail on renminbi-denominated securities and on securities issued by Chinese counterparties.

The circular cites no statutory article. The BCL’s general power to collect statistics sits in Article 32(1) of the Law of 23 December 1998 on the monetary status and the Banque centrale du Luxembourg, which authorises it to collect the statistical information it needs directly from economic agents. My reading is that S 1.9 rests on that power together with the Board decision recorded in the circular. The arrangement is still active: the BCL’s annual report for 2025 states that, under the 2014 Memorandum, the BCL follows developments in the renminbi market and regularly provides the PBoC with information on it.

The operative detail sits in four documents on the BCL’s S 1.9 page: the instructions, the report template, the compendium of verification rules with its annex, and an XML schema package. The instructions are short, seven pages, and defer most definitions to the BCL’s general document “Definitions and concepts for the statistical reporting of credit institutions”. The instructions, the template and the compendium each state that the French text prevails where it differs from the English.

Who must report S 1.9: resident banks with renminbi balances and trades

Section 1.1 of the instructions sets the population in one sentence: all resident credit institutions, regardless of their legal status, provided that they have CNY-denominated deposits and/or loans and that they engage in renminbi purchase and/or sale operations. The S 1.9 documents contain no size threshold, no exemption and no small-bank derogation. Legal form does not change the answer either, since the instructions draw no line between banks incorporated in Luxembourg and Luxembourg branches of banks incorporated elsewhere.

The activity trigger is less clear than it first looks. Read literally, it is cumulative: renminbi balances and renminbi purchases or sales. The instructions do not say what a bank with CNY deposits but no CNY trades should file, or whether the test applies month by month or once. Circular 2015/238 names the BCL’s Money and banking statistics unit (reporting.banques@bcl.lu) as the contact for questions on its application.

The S 1.9 documents leave the consolidation level implicit. The Definitions document says Luxembourg-law banks with foreign branches file some statistical reports twice: an L version for the Luxembourg head office and an N version for the whole entity including branches, a pattern S 2.5 follows with S 2.5-L and S 2.5-N. S 1.9 has no N twin. The BCL’s transmission manual lists a single file name, S0109_L0, and the cross-report checks run against S 2.5-L, the Luxembourg-entity return, which I read as a Luxembourg-entity perimeter.

The designated clearing bank sits at the edge of scope. Purchases and sales with the clearing bank in Luxembourg are excluded from every bank’s S 1.9 transaction lines, because a separate reporting template addressed directly to the clearing bank covers them. The instructions do not say whether the clearing bank itself also files S 1.9.

Counterparty residence leaves the scope unchanged. The circular says the BCL needs information on renminbi use by both resident and non-resident counterparts, and the template carries all-country lines alongside the Luxembourg lines.

What the report contains: 17 lines on loans, deposits and CNY trades

Section 3 of the instructions asks for two kinds of information: CNY-denominated loans and deposits, and transactions, meaning CNY sales and purchases with counterparts other than the clearing bank in Luxembourg. The report template turns that into three sheets after the cover page, Loans, Deposits and Transactions, with 17 lines in all.

Line Template item Counterparty scope
1-002000-XX-CNY-90000 Loans (claims) All countries, all sectors
1-002000-XX-CNY-32100 Loans (claims) All countries, credit institutions
1-002000-LU-CNY-90000 Loans (claims) Luxembourg, all sectors
1-002000-LU-CNY-32100 Loans (claims) Luxembourg, credit institutions
2-002000-XX-CNY-90000 Deposits (debts) All countries, all sectors
2-002000-XX-CNY-32100 Deposits (debts) All countries, credit institutions
2-002000-LU-CNY-90000 Deposits (debts) Luxembourg, all sectors
2-002000-LU-CNY-32100 Deposits (debts) Luxembourg, credit institutions
T-000000-XX-CNY-90000, with A- and V- Amounts of transactions in CNY from EUR or other currencies: total, purchases, sales All counterparties
T-000000-XX-CNY-32100, with A- and V- Of which: operations with other banks: total, purchases, sales Banks, all countries
T-000000-LU-CNY-32100, with A- and V- Of which: operations with banks in Luxembourg: total, purchases, sales Banks in Luxembourg

Each line code reads item, country, currency and sector. Items 1-002000 (loans) and 2-002000 (debts, which the template labels deposits) come from the BCL’s general instrument list, while the transaction sheet uses its own prefixes: T for the total, A for purchases and V for sales. XX is the BCL’s country code for “no breakdown”, which the Definitions document allows only where instructions ask for it, and LU is the ISO 3166 code. In the five-digit sector list, 32100 is credit institutions; the template labels 90000 as “no breakdown”.

Sector 32100 has a boundary worth checking in counterparty data. The Definitions document excludes investment firms that are reclassified as credit institutions on receiving a banking licence, the so-called systemic investment firms, and classifies them in the financial sector (40000) by main activity. A CNY loan to one of them belongs in the all-sector lines and stays out of the 32100 sublines.

The two halves measure different things. Loan and deposit lines are month-end stocks: section 2.2 of the instructions makes the last day of the month the reference date in principle, and the Definitions document, to which section 2.1 of the instructions refers, requires loans and deposits at nominal value. Nominal value is the principal the debtor is contractually obliged to repay, determined without regard to provisions and with write-offs excluded. Transaction lines are flows, the total volume of all operations that took place during the reference month (section 4.2).

Purchases and sales are reported gross and separately, and the verification annex fixes each T line as A plus V. The total is turnover in both directions. The BCL’s own sample file in the XML package shows the arithmetic: 15,000 in purchases and 10,000 in sales give a total line of 25,000.

The CNY in the line code is the currency of denomination. The amount itself follows section 2.3 of the Definitions document: statistical reports are drawn up in the bank’s accounting currency, amounts may carry up to five decimals, and positions in other currencies are converted at the exchange rate prevailing on the day the report is compiled. The S 1.9 XML header has a reportingCurrency field, which the BCL’s sample file fills with EUR. Neither document names the rate for converting a month’s transaction volumes.

Section 4.2.2 of the instructions says banks distinguish sales and purchases of CNY exchanged from EUR and other currencies. The template has one set of lines labelled “from EUR or other currencies” and no separate EUR dimension. My reading is that the purchase and sale split is the distinction meant, and that no EUR-only figure is expected. On signs, the compendium requires every line to be non-negative.

Several things are absent by design. There are no securities lines (the circular leaves those to security-by-security reporting), no maturity split (every line carries the “no breakdown” initial maturity code I999-999 in the XML), no interest rates and no off-balance-sheet items.

S 1.9 deadlines: ten working days after each month-end

Point Rule Source
Frequency Monthly Instructions, section 1.2
Reference date In principle the last day of each month Instructions, section 2.2
Remittance deadline No later than 10 working days after the end of the reference period Instructions, section 1.2
Working-day basis Working days defined by the ECB for national central banks’ transmission of statistics BCL remittance calendar, footnote 1
First mandatory period June 2015; earlier filing was allowed on a voluntary basis Circular BCL 2015/238
Record keeping Monthly reports and related documents kept for 24 months Definitions document, section 2.5

The BCL turns the rule into dates in an annual calendar of remittance dates for credit institutions. In the 2026 edition, issued in December 2025, S 1.9 L0 sits in the monthly table with S 1.1 L6, S 1.4 L3, S 1.8 L2 and S 1.12-L L0, and all five share the same date every month, while S 1.5 L4 is due a few days later. The 2026 dates fall between the 12th and the 18th of the following month. The December 2026 reference month, for example, is due on 15 January 2027.

The month now closing is therefore due in the middle of the next month, on the date the current calendar prints. Because the footnote bases the dates on ECB-defined working days, my reading is that the printed calendar date is the operative deadline whenever a bank’s own count of ten days would produce a different one. The CSSF’s prudential deadlines run on a separate track, as our CSSF reporting calendar for Q3 2026 shows.

There is no annual or quarterly S 1.9 cycle, so the next applicable reference date is always the next month-end. Quarter-ends add a second test. The S 2.5-L quarterly balance sheet is due later than S 1.9, on the 20th of the month after the quarter in the 2026 calendar, and its compendium checks the S 1.9 loan and deposit lines against it. A March, June, September or December S 1.9 that passes its own rules can still draw a query once S 2.5-L arrives.

Submission of the S0109_L0 XML file through Sofie or e-file

S 1.9 is filed as an XML file built on the schema package published on the S 1.9 page. The package, S19_L0_Schema_XML_v1_0_r110, with files dated January 2015, holds the main schema S19.xsd, two supporting schemas (structures.xsd for shared structures and datatypes.xsd for code formats), HTML documentation and an example file. The root element S19 carries a version attribute fixed at 1.0 and a mandatory creation date and time.

The header has six fields: endMonthDate, closingDate, reporterID, declarantID, reportingCurrency and layout, which is 0. The content block has three optional parts, assets for the loan lines, liabilities for the deposit lines and transactions for the purchase and sale lines. Each reportedLine pairs an identifier (item or transaction type, country, currency, sector and initial maturity) with a reportedAmount, a decimal of up to five fraction digits.

The schema also blocks duplicate lines. Within each of the three blocks, a uniqueness constraint covers the five identifier fields together, so the same line cannot appear twice in one file. The BCL’s transmission manual adds a limit worth knowing: the schema checks formats, and a code that respects the format is not necessarily valid for the report.

File naming comes from the “Manual of electronic transmission for the statistical reporting of credit institutions”, February 2021 edition, last updated on the BCL site on 8 March 2021. It lists the S 1.9 name as S0109_L0_yyyymm_Rrrrrrrrrr_Dddddddddd_yyyymmdd_nnn. The parts are the report code, layout 0, the reference year and month, the reporter, the declarant, the file creation date and a sequence number. The example in the schema package is S0109_L0_201412_B000000999_B000000999_20150112_001.xml.

The manual separates the reporter, the entity that submits the data, from the declarant, the entity whose data are reported. Banks use the letter B, followed by the identification number the CSSF allocates, padded with leading zeros to nine digits. In the XML the identifier types are 23 for the CSSF number of a bank and 32 for the CSSF number of a professional of the financial sector, which appears as P in the file name. The sequence number restarts at 001 each day and 000 may not be used.

The manual names two channels, Sofie and e-file, and adds that the BCL will accept any new secure channel accepted by both the BCL and the reporting agent. E-mail is closed: circular letter ST.24-0013 of 15 January 2024 told reporters that the BCL would no longer accept statistical reports sent by e-mail. The principle of a freely chosen but BCL-approved secure channel goes back to Circular BCL 2007/216 on remote transmission of statistical data.

One document has dropped out. Circular 2015/238 listed a “Manual of electronic transmission for report S 1.9” among the reporting documents, but the S 1.9 page today offers the XML package and no report-specific manual, so the general manual is the naming reference. On resubmission the sources are silent: the daily sequence number, which lets a bank send several files for the same report on one day, is the only versioning mechanism they describe.

The BCL’s April 2025 document “Feedbacks for the statistical reports” lists S0109 among 17 collections that can receive up to three feedback types, which it says will be set up in the near future. FL-OK or FL-NOK reports whether the file was processed or has technical errors, DQ-FDB flags data points the BCL needs corrected or confirmed, and ADHC-FDB carries requests outside the normal cycle. When the document was issued, technical errors and data quality requests still went out by e-mail, with delivery through Sofie and e-file to follow in stages, announced report type by report type, along the lines already used for BCL AnaCredit reporting. Feedback files start with FDBBUSI and carry the name of the file they answer, and each one sets its own response deadline.

Validation: 15 internal rules and the S 2.5-L equality checks

The compendium of verification rules for S 1.9 is dated January 2015, and the BCL page shows an update on 16 April 2015 with a revision-marked version. It splits rules into permanent rules, which software providers are invited to implement, and temporary rules addressed to reporting agents. S 1.9 has permanent rules only.

Two internal checks apply. Every line must hold a non-negative value, and the annex lists 15 hierarchical rules, numbered S0109-L_L0_0001 to S0109-L_L0_0015.

Rules Annex sheet Test
0001 to 0004 Loans XX-32100 and LU-90000 each less than or equal to XX-90000; LU-32100 less than or equal to both XX-32100 and LU-90000
0005 to 0008 Deposits The same four relations for item 2-002000
0009 to 0012 Transactions 1 (simple relations) Purchases and sales with other banks within the all-counterparty figures; purchases and sales with banks in Luxembourg within the other-banks figures
0013 to 0015 Transactions 2 (complex relations) Each total equals purchases plus sales, for all counterparties, other banks and banks in Luxembourg

The cross-report rules carry more weight. The S 1.9 compendium refers to the S 2.5-L compendium for the consistency checks between the two returns, and the current S 2.5-L compendium (April 2022, last updated on the BCL site on 21 April 2022) sets them out in section 2.1.2. Its annex, last updated on 18 August 2021, holds four asset-side rules, S0205-L_L0_A2_0001 to 0004, and four liability-side rules, S0205-L_L0_P2_0001 to 0004. Each one sets an S 1.9 line equal to the matching S 2.5-L amount in CNY plus the matching amount in CNH.

Section 2.1.2 explains the mapping. The S 1.9 deposit item 2-002000 corresponds to the sum of S 2.5-L items 2-002010, 2-002020, 2-002030 and 2-002040. Country code XX corresponds to the sum of all country codes used in S 2.5-L, and sector 90000 to the sum of all sector codes, while S 2.5-L is summed across all initial maturities. No annex rule touches the S 1.9 transaction lines; S 2.5-L reports stocks.

The sources reviewed contain no BCL statistics on S 1.9 errors, so the most reliable map of failure points is the rule set itself. Read together, the rules fail or query a file when:

  • any line carries a negative value;
  • a credit-institution or Luxembourg subline exceeds its parent line;
  • a total line differs from purchases plus sales, for instance where the two have been netted;
  • the same line identifier appears twice in one block of the XML;
  • a quarter-end loan or deposit line differs from the S 2.5-L total of CNY plus CNH for the same scope.

The last test is easy to miss. The S 1.9 compendium only points to it, and the rules themselves are written into the S 2.5-L compendium and its annex.

Caveats: CNH, the clearing bank and the ECB compliance framework

The CNH question came up within months of launch. Circular letter ST.15-0126 of 16 April 2015 answered banks that had asked whether S 1.9 meant CNY positions only. The BCL explained that the renminbi trades onshore as CNY and offshore, mainly in Hong Kong, as CNH at a usually slightly different rate, and that ISO 4217 has no CNH code although the BCL accepts it. Because a restriction to CNY would fail to measure the use of the currency, the BCL modified the S 1.9 verification rules to group all renminbi operations under CNY, whether denominated in CNY or CNH, while continuing to accept both codes in S 2.5-L and S 2.5-N.

The result is a mapping rule that differs by report. A CNH balance goes into S 2.5-L under CNH and into S 1.9 under CNY, and the A2 and P2 rules check exactly that combination. The XML schema will not stop a CNH line, since its currency type accepts any three-letter code; the grouping is enforced through the BCL’s verification rules.

The clearing-bank exclusion is narrower than it looks. Sections 3 and 4.2 of the instructions exclude purchases and sales with the clearing bank in Luxembourg; neither section excludes loans to it or deposits from it. My reading is that a CNY balance with the clearing bank therefore stays in the stock lines, under Luxembourg credit institutions (LU, 32100). The reporting documents identify the clearing bank only as the one designated by the People’s Bank of China, and the 2014 designation of ICBC Luxembourg Branch is recorded in Circular 2015/238.

The compliance framework is the open question. Circular letter ST.24-0013 says Regulation (EU) 2022/1917 (ECB/2022/31) on infringement procedures applies from 30 April 2024 to the BCL collections listed in its Annex I, and that the ECB and the BCL monitor compliance with requirements laid down in ECB regulations and decisions. The annex lists ECB regulations only, with no renminbi collection among them. The BCL’s April 2025 feedback document, by contrast, lists S0109 with 16 other collections and says that meeting feedback deadlines falls within the ECB non-compliance framework set out in Regulation 2022/1917 and ST.24-0013. The sources do not reconcile the two for a national return such as S 1.9, and I would not read either as settling whether an ECB sanction could attach to it.

Proportionality, waivers, national discretions and transitional provisions do not feature in the S 1.9 documents. The only transitional element was the circular’s permission to file before June 2015 on a voluntary basis. Two other returns carry data the BCL documents tie to S 1.9: S 2.5-L, which holds the same renminbi loan and deposit stocks quarterly with CNY and CNH split, and the monthly security-by-security report, which holds renminbi securities. The S 1.1 monthly balance sheet compendium has no rule comparing it with S 1.9.

8 June 2026 ECB press release on IReF milestones Planned consultation in the second half of 2027 and first IReF reporting in the second quarter of 2031, subject to adoption of the IReF Regulation; S 1.9 not named

The report itself has barely moved. Layout 0 from January 2015 is still the only layout on the S 1.9 page, and the changes since the April 2015 CNH letter have come from around it: the general transmission manual, the end of e-mail transmission and the feedback scheme.

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 IReF reporting from the second quarter of 2031, with an initial one-year parallel phase during which existing statistical reporting within the scope of IReF will continue alongside IReF reporting. The ECB states that these timelines are subject to adoption of the IReF Regulation, pending the outcome of the consultation.

Neither the ECB announcement nor the BCL’s IReF page names S 1.9. The BCL says an implementation plan is being prepared that will set out how the individual national collection frameworks will evolve and how the residual country-specific requirements will be modelled. With no ECB regulation behind it, S 1.9 turns on that plan in my reading; nothing published so far retires or changes it. The ECB scheduled an industry workshop on 3 November 2026 covering the modelling of reporting requirements and the approach to country-specific requirements under IReF.

The reductions covered in our note on the ECB supervisory reporting cuts confirmed at Bruegel belong to the supervisory track. S 1.9 is a BCL statistical collection, so in my reading its path runs through IReF and the BCL’s national plan.

Frequently Asked Questions

Is a conversion between CNY and CNH a purchase or sale of CNY?

The instructions define the transaction lines as purchases and sales of CNY exchanged from EUR or other currencies. Circular letter ST.15-0126 requires S 1.9 to group renminbi operations under CNY, whether denominated in CNY or CNH. Neither that letter nor the S 1.9 instructions expressly establishes whether a direct conversion between CNY and CNH must enter transaction turnover. Reporting banks should confirm the treatment with the BCL before excluding such conversions.

Do FX forwards and swaps count in the monthly volumes, and on trade date or value date?

The instructions cover “all transactions in CNY” and the total volume of operations that took place during the reference month. The S 1.9 instructions do not specify whether forwards and swaps are included, how individual legs should be counted, or whether transaction volumes should be allocated by trade date or value date. This absence of detail does not authorise a bank to select any reporting convention. The appropriate treatment should be confirmed with the BCL before implementing transaction-recognition logic.

Are a client’s currency conversions included, or only the bank’s own-account trades?

No own-account restriction appears in the instructions, and the first counterparty group is “all counterparties”. My reading is that a client buying renminbi from the bank is a CNY sale by the bank to a non-bank counterparty. It belongs in the all-counterparty sale line V-000000-XX-CNY-90000 and stays out of both bank sublines.

What does S 1.9 look like in a month with no renminbi business?

In S19.xsd the assets, liabilities and transactions blocks are each optional, so a file with a header and an empty content block validates against the schema. The instructions do not say whether a bank inside the population should send such a file or nothing at all. That gap is one to raise with the BCL.

Should the S 1.9 loan and deposit figures match the bank’s FINREP or other supervisory figures?

No published rule compares S 1.9 with supervisory returns; the only cross-report checks are the S 2.5-L rules. Differences are also built in. The Definitions document applies supervisory valuation rules in general but requires loans and deposits at nominal value at month-end, without provisions and excluding write-offs, so a statistical CNY loan figure can differ from its carrying amount in supervisory data.

Where does a renminbi deposit from a foreign central bank go?

Central banks, including the ECB, carry sector 31000 in the BCL’s sector list. A deposit from a central bank therefore enters only the all-sector deposit line, 2-002000-XX-CNY-90000, and stays out of the credit-institution sublines coded 32100.

Key Takeaways

  • Scope test: a resident credit institution of any legal form with CNY loans or deposits and CNY purchases or sales is in the S 1.9 population; no size threshold or exemption applies.
  • S 1.9 groups CNY- and CNH-denominated renminbi balances under CNY, while the BCL continues to accept both codes in S 2.5-L; the S 2.5-L verification annex sets each S 1.9 loan and deposit line equal to the S 2.5-L CNY plus CNH total.
  • Keep clearing-bank trades out of the transaction lines; the instructions exclude no loans or deposits, so in my reading clearing-bank loans and deposits stay in the stock lines under LU and 32100.
  • Report purchases and sales gross on separate A and V lines; the T line is their sum, never a net figure.
  • Express amounts in the accounting currency with up to five decimals, use maturity code I999-999, and use XX and 90000 only where the template shows them.
  • Send the S0109_L0 XML file through Sofie or e-file by the date in the BCL’s remittance calendar, mid-month after the reference month; e-mail submissions are refused.
  • Track the BCL’s IReF implementation plan for national requirements and the ECB consultation planned for the second half of 2027.

Before the next S 1.9 file leaves the bank

For the month now closing, the deliverable is an S0109_L0 XML file of up to 17 lines, sent through Sofie or e-file by the date printed in the BCL’s remittance calendar. Three checks follow directly from the rules: the renminbi extraction picks up CNH accounts as well as CNY, each T line equals its A and V lines, and at quarter-end the loan and deposit lines tie to the CNY plus CNH totals in S 2.5-L. Questions on the activity trigger or nil months go to the BCL’s Money and banking statistics unit at reporting.banques@bcl.lu, the contact named in Circular 2015/238.
