Grossing-up of MFI balance sheet items

1. Where NCBs grant derogations to MFIs in accordance with paragraphs 1, 2, 4, 6 and 7 of Article 9 of Regulation (EU) 2021/379 (ECB/2021/2), NCBs shall gross up the statistical information collected pursuant to that Regulation to represent the entire reporting population for the purposes of compiling the monthly and quarterly statistical information to be reported to the ECB in accordance with this Section.

2. Where NCBs gross up statistical information pursuant to paragraph 1, they shall apply at least one of the following: (a) for information on missing breakdowns, estimates shall be derived by applying ratios based on a subset of the actual reporting population considered to be most representative of the tail institutions as follows: (i) NCBs of Member States whose contribution to the aggregated MFI balance sheet of the euro area exceeds 2 % shall determine this subset so that the total balance sheet of the entities in the subset does not exceed 35 % of the national aggregated MFI balance sheet; (ii) NCBs of Member States whose contribution to the aggregated MFI balance sheet of the euro area does not exceed 2 % shall determine this subset so that the total balance sheet of the entities in the sub-set does not exceed 35 % of the national aggregated MFI balance sheet, unless the grossing-up according to this approach would incur significant costs for the NCB, in which case the NCB may apply ratios based on the actual reporting population instead; (iii) the requirements to determine subsets of the actual reporting population referred to in sub-paragraphs (i) and (ii) shall not apply when the balance sheets of the institutions to which the derogations are granted account does not exceed 1 % of the national aggregated MFI balance sheet. In such cases the NCB may apply ratios based on the actual reporting population instead; (b) in applying point (a), both the tail institutions and the subset of the actual reporting population may be subdivided into different groups by reference to the type of institution; (c) where the combined contribution of MMFs granted derogations pursuant to Article 9(1) of Regulation (EU) 2021/379 (ECB/2021/2) exceeds 30 % of the national MMF balance sheet, NCBs shall gross up the statistical information relating to MMFs separately from deposit-taking corporations and in accordance with one of the following: (i) NCBs shall use the statistical information collected from MMFs that are not granted derogations pursuant to Article 9(1) of Regulation (EU) 2021/379 (ECB/2021/2) where that statistical information is sufficiently representative for the purposes of grossing up; (ii) NCBs shall estimate a balance sheet for the MMF sector from alternative sources of information, at least once a year, and use it as the basis for grossing up where all MMFs are granted derogations pursuant to Article 9(1) of Regulation (EU) 2021/379 (ECB/2021/2), or if the statistical information collected from MMFs that are not granted derogations pursuant to Article 9(1) of Regulation (EU) 2021/379 (ECB/2021/2) is not sufficiently representative for the purposes of grossing up; (d) where statistical information is collected pursuant to Regulation (EU) 2021/379 (ECB/2021/2) at a lower frequency or with later timeliness than the statistical information to be reported to the ECB pursuant to this Guideline, NCBs shall estimate the statistical information for the missing periods by either: (i) repeating the information where the results have proven to be adequate; or (ii) applying appropriate statistical estimation techniques to take account of any trends or seasonal patterns. For the purposes of points (a) to (d), the ratios or any other intermediate calculation used for grossing up may be derived from information obtained from supervisory authorities where that information is sufficiently aligned with the statistical information to be grossed up.

3. Where NCBs have granted a derogation to MFIs pursuant to Article 9(7) of Regulation (EU) 2021/379 (ECB/2021/2), they shall gross up by estimating the quarterly statistical information to be reported to the ECB pursuant to Article 4 as follows: (a) where NCBs collect statistical information from MFIs pursuant to Regulation (EU) 2021/379 (ECB/2021/2) at a lower frequency than quarterly, they may use that statistical information for the purposes of estimating the statistical information for the missing periods, or they may apply appropriate statistical estimation techniques to take account of any trends or seasonal patterns; (b) where NCBs collect statistical information from MFIs pursuant to Regulation (EU) 2021/379 (ECB/2021/2) at a more aggregated level, they may use that statistical information for the purposes of estimating the statistical information to be reported to the ECB pursuant to Article 4, or they may use suitable breakdowns as a basis for such estimates; (c) where NCBs collect quarterly statistical information pursuant to Regulation (EU) 2021/379 (ECB/2021/2) from MFIs which covers at least 80% of deposits, loans and debt securities holdings and investment fund shares/units, collectively, of residents in the non-euro area Member State in respect of which the derogation applies, they shall estimate the statistical information to be reported on that basis; or (d) where NCBs estimate the statistical information to be reported on the basis of alternative sources, they shall make the necessary adjustments to take into account differing concepts and definitions applied pursuant to Regulation (EU) 2021/379 (ECB/2021/2) as compared to those applied in those alternative sources.

ANNEX I

REPORTING OF ADJUSTMENTS AND THE DERIVATION OF TRANSACTIONS

PART 1

General description of the procedure for deriving transactions

Financial transactions are the net acquisition of financial assets or the net incurrence of liabilities for each type of financial instrument, i.e. the sum of all financial transactions that occur during the relevant reference period. The framework for deriving transactions for monetary financial institutions (MFI) balance sheet items (BSI) is based on the European System of Regional and National Accounts (hereinafter the ‘ESA 2010’) established by Regulation (EU) No 549/2013 of the European Parliament and of the Council ( 9 ). Deviations from this international standard are made concerning both the data content and names of statistical concepts, where necessary. This Annex is interpreted in accordance with the ESA 2010, unless Regulation (EU) 2021/379 (ECB/2021/2) ( 10 ) or this Guideline explicitly or implicitly override its provisions.

In the context of BSI statistics, the ECB calculates transactions by taking, for each asset and liability item, the difference between outstanding amounts at end-period reporting dates and then removing the effect of developments that are not the result of transactions (‘adjustments’). These are grouped into the main categories ‘reclassification adjustments’, ‘revaluation adjustments’, and ‘exchange rate adjustments’. National central banks (NCBs) report ‘reclassification adjustments’ and ‘revaluation adjustments’ to the ECB so that these non-transaction effects can be removed in the calculation of transactions. ‘Exchange rate adjustments’ are normally derived by the ECB. Transactions are calculated on a net basis, i.e. there is no requirement to identify gross financial transactions or turnover. Financial transactions should generally be measured at the transaction value – the value at which assets are acquired/disposed of and/or liabilities are created, liquidated or exchanged – which may not necessarily be the same as the price listed in the market or the fair value of the asset at the time of the transaction. The transaction value does not include service charges, fees, commissions, or similar payments for services provided in carrying out the transaction.

This Annex reviews the methodology for deriving transactions in the context of BSI statistics. Part 2 focuses on the principles for the reporting of adjustments from the NCBs to the ECB ( 11 ). Part 3 then looks at special adaptations made in the compilation framework for BSI statistics.

Further details and numerical examples are provided in the ‘Manual on MFI balance sheet statistics’ published on the ECB's website.

PART 2

Reporting of adjustments from the NCBs to the ECB

1. Underlying principles for adjustments

Reclassification and revaluation adjustments are subject to the same double-entry accounting system as outstanding amounts and are therefore balanced. Where a balancing item is required due to the different valuations which apply to the statistical, as compared to the accounting, balance sheet – i.e. a ‘statistical/accounting discrepancy’ – this should be recorded in ‘remaining liabilities’ (as a positive or negative amount, as appropriate).

Interest on deposits, loans and debt securities issued and held should be recorded on an accrual basis, but should never be recorded as a transaction with the instrument concerned. For loans and deposits this is guaranteed by the requirement specified in Part 2 of Annex II to Regulation (EU) 2021/379 (ECB/2021/2) to record accrued interest on these instruments in ‘remaining assets’ and ‘remaining liabilities’. The Regulation, however, contains no rule on the treatment of accrued interest on debt securities issued or held. In fact, accrued interest is often intrinsic to market prices and difficult to disentangle from the accounting price as it is reported in the statistical balance sheet. In the interest of coherent and cross-country comparable data, the following should be applied:

(a) if accrued interest is intrinsic to the accounting price as it is reported in the statistical balance sheet, it should be subject to a revaluation adjustment;

(b) if accrued interest is excluded from the outstanding amount of the securities to which it relates in the statistical balance sheet, it is classified under ‘remaining assets’ or ‘remaining liabilities’, and not treated as a revaluation adjustment.

This suggested treatment is also reflected in the reporting requirements laid down in this Guideline (see Part 1 of Annex II).

When a monthly adjustment is reported, it may affect the breakdowns of items reported quarterly. Consistency should be ensured between the two sets of data, i.e. where applicable, the sum of the monthly adjustments must equal the quarterly adjustment. If a threshold is established for the quarterly adjustments, or the quarterly adjustments cannot be identified in full or to the same level of detail as the monthly adjustment, the adjustment is calculated so as to avoid discrepancies with the adjustment reported for the monthly data.

2. Reclassification adjustments

‘Reclassification adjustments’ comprise any change in the balance sheet of the reference sector that arises as a result of changes in the composition and structure of the reporting population, changes in the classification of financial instruments and counterparties, changes in statistical definitions and the (partial) correction of reporting errors, all of which give rise to breaks in the series and thereby affect the comparability of two successive end-of-period outstanding amounts. Euro area enlargements can be viewed as a special case of reclassification.

NCBs report data on reclassification adjustments, as specified in this Guideline, using data directly reported by the reporting population, supervisory information, plausibility checks, ad hoc enquiries (e.g. related to outliers), national statistical requirements, information on joiners and leavers of the reporting population and any other source available to them. NCBs identify changes in outstanding amounts that are due to reclassifications and report the net amount. A net increase in outstanding amounts due to reclassifications is entered with a positive sign, a net decrease in outstanding amounts with a negative sign.

Estimates of reclassification adjustments may be made by NCBs, in particular when the information is not readily available or of poor quality. The ECB is not expected to make ex post adjustments unless the NCBs identify sharp changes due to reclassifications in the final data which cannot be corrected in due time by the NCBs. In this case the ECB may make ex post adjustments in agreement with the relevant NCB.

In principle, NCBs report ‘reclassification adjustments’ for each item specified in this Guideline. In cases where the estimated reclassification amounts are below EUR 5 million for the own balance sheet of the NCB, or below EUR 50 million for the aggregated balance sheet of other reporting agents, NCBs may report reclassification adjustment amounts of zero or as a missing value. These thresholds are intended to help the NCBs decide whether to compile adjustments or not. However, where relatively detailed information is collected regardless of the threshold, it may be counterproductive for the NCB to try to apply such a threshold. This flexibility is without prejudice to the requirement for consistency within the reported data for the reference period, and between monthly and quarterly data, as described below.

Within the limits defined by the revision policy, NCBs correct reporting errors in outstanding amounts as soon as the errors are identified. Ideally, the corrections entirely remove the error from the outstanding amounts, especially where the error affects a single period or a limited time range. In these circumstances, no break in series occurs. However, where the error affects historical data and no correction of past data is made or is made only for a limited time range, then a break occurs between the first period with the corrected figure and the last period containing the incorrect figure. In this case, NCBs identify the size of the break that occurs and enter an adjustment under ‘reclassification adjustments’. Similar practices apply to the implementation of changes of statistical definitions affecting reported data, as well as to correcting for breaks that may be due to the introduction, change or abandonment of grossing-up methods.

The boundary for treating transfers of assets as transactions is defined by the existence of two separate institutional units which act by mutual agreement. If, however, the transfers occur as a result of the creation or disappearance of an institutional unit, they should be treated as ‘reclassification adjustments’. In particular, if a merger or acquisition leads to the disappearance of one or more institutional units, all cross-positions that existed between the merging institutions are netted at the time when the units cease to exist from the system and reclassification adjustments must be reported accordingly. Corporate divisions are treated symmetrically.

3. Revaluation adjustments

‘Revaluation adjustments’ reported pursuant to this Guideline are normally compiled by NCBs on the basis of data directly reported by the reporting agents. NCBs, however, may also cover these reporting requirements indirectly (e.g. by collecting data on transactions directly) or via security-by-security data or other data reported by the reporting population and in any case are permitted to collect additional data from reporting agents as necessary.

4. Exchange rate adjustments

Movements in exchange rates against the euro that occur between end-period reporting dates give rise to changes in the value of foreign currency assets and liabilities when expressed in euro. NCBs should report assets and liabilities denominated in foreign currencies translated into euro using the ECB reference exchange rates prevailing on the day to which the data relate. As any changes in outstanding amounts resulting from movements in exchange rates represent holding gains/losses and are not financial transactions, the valuation effects need to be identified so that they can be excluded from transactions. Revaluation adjustments due to exchange rate changes may also contain valuation changes that arise from transactions in assets/liabilities, i.e. realised gains/losses; however, there are divergent national practices in this respect.

The ECB normally derives the necessary exchange rate adjustments based on the statistical information provided by NCBs. Where NCBs are in a position to compile more accurate exchange rate adjustments, they may instead agree with the ECB to transmit exchange rate adjustments which will be used by the ECB to derive transactions.

The NCBs include adjustments data on money market funds (MMFs) when fulfilling their reporting obligations in respect of ‘reclassification adjustments’ and ‘revaluation adjustments’. These adjustments are also reported separately for MMFs in accordance with the dedicated quarterly reporting scheme.

NCBs report reclassification adjustments where there is a change in the MMF reporting population, as defined in Article 2 of Regulation (EU) 2021/379 (ECB/2021/2), resulting from amendments to the scope of entities authorised as MMFs in accordance with Regulation (EU) 2017/1131 of the European Parliament and of the Council ( 12 ). A change in the MMF reporting population that results from a change in a fund’s investment policy is recorded as a financial transaction and not as a reclassification. This follows from the fact that any change in investment policy has to be agreed by the investors prior to the change and is therefore seen as an active investment decision.

Article 9(6) of Regulation (EU) 2021/379 (ECB/2021/2) provides that NCBs may grant derogations to some or all MMFs in respect of the reporting of revaluation adjustments. In these cases, NCBs should nevertheless provide information on a best estimate basis where the amounts involved are significant, in accordance with Article 5(2) of this Guideline.

The calculation of revaluation adjustments on MMF assets follows the common procedure applicable to all MFIs. On the liabilities side, positive changes in the value of MMF shares/units have traditionally been considered as transactions, in parallel to the payment (as opposed to the accrual) of interest on deposits, implying that the counterpart of the revaluations on the assets side would not be ‘money market fund shares/units’ but ‘remaining liabilities’. However, with respect to cases where MMF shares/units decline in price as a result of losses on the fund’s assets, this cannot be compared to interest payments. Against this background, Table 1A of Part 4 of Annex I to Regulation (EU) 2021/379 (ECB/2021/2) includes requirements on revaluation adjustments for MMF shares/units; NCBs should use this item to balance the price revaluations on the assets side, where relevant. The allocation should be performed in such a way as to only cover the actual price revaluations that are reflected as changes in the value of MMF shares/units.

2. Individual MFI balance sheet item (IBSI) statistics

In accordance with Article 16(2) of this Guideline, NCBs report ancillary series covering revaluation and reclassification adjustments (see Part 2 of this Annex) and loan transfers on a best efforts basis.

In order to reduce the reporting burden, NCBs may apply a threshold approach when deriving the ancillary series. In particular, for where the absolute amount of the ancillary series to be reported is below the maximum of EUR 50 million and 1 % of the respective outstanding amount, i.e. threshold = max(EUR 50 million, 1 % of outstanding amount), NCBs may instead report the amount as zero or as a missing value. This threshold, which also applies to groups of credit institutions, is indicative and aims to help NCBs to decide whether to make an adjustment or not. Where the information is not readily available or is of a poor quality, the NCB may decide either to make estimates or to report a missing value.

In addition and in accordance with this Guideline, NCBs are only required to report ancillary series for credit institutions that are not core institutions to the extent that the statistical information are collected from those credit institutions in accordance with Regulation (EU) 2021/379 (ECB/2021/2). Where none of the statistical information required for reporting an ancillary series is available from the credit institutions that are not core institutions, NCBs may report a missing value.

3. POGIs and central government

NCBs report, where relevant, statistical information on POGIs and central government covering their monetary liabilities vis-à-vis euro area resident non-monetary financial institutions and their holdings of cash and securities issued by euro area MFIs in accordance with Section 6 of this Guideline. For the purpose of compiling transactions, adjustments are, in principle, also provided in line with the requirements established for MFI balance sheet statistics, although in practice changes due to exchange rate or market price changes are unlikely to occur. These data are reported as indicated in Annex VI.

Table 1: Revolving loans and overdrafts and convenience and extended credit card credit Sector Type of instrument New business indicator Reporting obligation Loans in EUR To households Revolving loans and overdrafts, convenience and extended credit card credit 86 AAR/NDER, amount To non-financial corporations Revolving loans and overdrafts, convenience and extended credit card credit 87 AAR/NDER, amount

1. For the purpose of MIR statistics, ‘revolving loans and overdrafts’, ‘convenience credit card credit’ and ‘extended credit card credit’ have the same meaning as described in Part 2 of Annex II to Regulation (EU) 2021/379 (ECB/2021/2) ( 13 ), regardless of their initial period of interest rate fixation. Penalties on overdrafts applied as component of other charges, e.g. in the form of special fees, are not covered by the annualized agreed rate (AAR) as defined in Part 1 of Annex I to Regulation (EU) No 1072/2013 (ECB/2013/34) of the European Central Bank ( 14 ). An AAR or narrowly defined effective rate (NDER) is reported for the categories included in Table 1 of this Annex. The reporting of the AAR/NDER is accompanied by the related new business volumes.

2. In the case of revolving loans and overdrafts, convenience credit card credit and extended credit card credit, the concept of new business volumes is equivalent to outstanding amounts. Indicators 86 and 87 are calculated on the basis of items 12, 23, 32 and 36 in Appendix 2 of Annex I to Regulation (EU) No 1072/2013 (ECB/2013/34), and the outstanding amounts reported for revolving loans and overdrafts, convenience credit card credit and extended credit card credit in accordance with Annex I to Regulation (EU) 2021/379 (ECB/2021/2). Interest rates are calculated as weighted averages of the corresponding items in Appendix 2 to Annex I to Regulation (EU) No 1072/2013 (ECB/2013/34), taking a zero interest rate for convenience credit card credit. Indicators 86 and 87 are intended to provide continuity with indicators 12 and 23 (‘overdrafts’) as previously defined in (now repealed) Regulation (EC) No 63/2002 (ECB/2001/18) ( 15 ), i.e. prior to their amendment by Regulation (EC) No 290/2009 (ECB/2009/7) ( 16 ).

3. For the purpose of MFI interest rate statistics, renegotiated loans to households and non-financial corporations comprise all new business loans, other than revolving loans and overdrafts and credit card debt, which have been granted but not yet repaid at the time they are renegotiated. In respect of loans transferred from another institution, renegotiation refers to new business loans that were granted by the institution selling or handing over the loan. Only an AAR or NDER is reported for the categories included in Table 2 on a best efforts basis in addition to the volumes required under Regulation (EU) No 1072/2013 (ECB/2013/34).

PART 2

Selection of the actual reporting population and maintenance of the sample for MFI interest rate statistics

Section 1: Selection of the actual reporting population

1. Overall selection procedure

1. NCBs apply the procedure illustrated in the figure below to select the reporting agents for the collection of MFI interest rate statistics in accordance with Regulation (EU) No 1072/2013 (ECB/2013/34). This procedure is defined as follows:

2. Census or sample

2. Each NCB selects its reporting agents from among the MFIs, except central banks and MMFs, in the reference reporting population that are resident in the same Member State whose currency is the euro (‘euro area Member State’) as the NCB.

3. In order to select the reporting agents, NCBs must either apply a census or follow a sampling approach in line with the requirements established in the following paragraphs.

4. In the case of a census, the NCB asks each resident MFI in the reference reporting population to report MFI interest rate statistics. The variables to be collected by means of the census are the interest rates and the amounts of new business and the interest rates on outstanding amounts.

5. In the case of a sample, only a selection of the MFIs in the reference reporting population will be asked to report. The variables to be estimated by means of the sample are the interest rates and the amounts of new business and the interest rates on outstanding amounts. They are referred to as sampling variables. In order to minimise the risk that the results of a sample survey deviate from the true (unknown) values in the reference reporting population, the sample should be constructed in such a way that it is representative of the reference reporting population. For the purpose of MFI interest rate statistics a sample is considered representative if all the characteristics that are relevant for MFI interest rate statistics and inherent in the reference reporting population are also reflected in the sample. To draw the initial sample, NCBs may use suitable proxies and models to produce the sampling scheme even if the underlying data, which are derived from existing sources, do not perfectly match the definitions in Regulation (EU) No 1072/2013 (ECB/2013/34).

3. Stratification of the reference reporting population

6. In order to ensure that the sample is representative, each NCB that chooses the sampling approach for MFI interest rate statistics should suitably stratify the reference reporting population prior to the selection of any reporting agents. Stratification implies that the reference reporting population N is subdivided into sub-populations or strata N1, N2, N3… NL. These subdivisions into sub-populations or strata must not overlap and together comprise the reference reporting population:

N1 + N2 + N3 + … + NL = N

7. NCBs define stratification criteria that allow the subdivision of the reference reporting population into homogeneous strata. Strata are considered homogeneous if the sum of the intra-stratum variances of the sampling variables is substantially lower than the total variance in the entire actual reporting population ( 17 ). The stratification criteria are linked to MFI interest rate statistics, i.e. there is a relationship between the stratification criteria and the interest rates and amounts to be estimated from the sample.

8. Each NCB that chooses the sampling approach must identify at least one stratification criterion to ensure that the sample of MFIs is representative of the relevant euro area Member State and the sampling error is small. NCBs should make efforts to define a hierarchy of stratification criteria. These must take national circumstances into account and be specific for each euro area Member State.

9. The selection of the reporting agents takes place in the form of single-stage sampling after all strata have been defined. Only at this stage are reporting agents drawn from the reference reporting population. No intermediate drawing should be carried out.

4. Allocation of sample across strata and selection of reporting agents

10. After defining the national strata in accordance with paragraphs 6 and 7, NCBs that choose the sampling approach draw the sample by selecting the actual reporting agents from each stratum. The total national sample size n is the sum of the sample sizes n1, n2, n3, …, nL for each of the strata:

n1 + n2 + n3 + … + nL = n.

11. Each NCB chooses the most appropriate allocation of the national sample size n among the strata. Therefore, for each stratum, NCBs define how many reporting agents nh are drawn from the total of MFIs, Nh. The sampling rate nh/Nh for each stratum h permits the estimation of the variance of each stratum. This implies that at least two reporting agents are selected from each stratum.

12. In order to select the actual reporting agents within each stratum, NCBs either include all institutions in the stratum, carry out random sampling or select the largest institutions per stratum. In the case of a random sample, the random drawing of the institutions within each stratum is either carried out with equal probability for all institutions or with probability proportional to the size of the institution. NCBs using random sampling or selection of the largest institutions may choose to include all institutions for some strata.

13. Information about the size of each credit institution and other institutions in the reference reporting population is available at national level from the MFI balance sheet statistics collected in accordance with Regulation (EU) 2021/379 (ECB/2021/2). NCBs must use total euro-denominated deposits and loans vis-à-vis households and non-financial corporations resident in the euro area Member States, which is that part of the balance sheet that is relevant for MFI interest rate statistics, or a close proxy.

14. MFI interest rate statistics must be based on a selection without replacement, i.e. each MFI in the reference reporting population may only be selected once.

15. If an NCB decides on a census of all MFIs in a stratum, the NCB may sample in that stratum at the level of branches. The precondition is that the NCB has a full list of branches that covers all the business of the credit and other institutions in the stratum, and has appropriate data in order to be able to assess the variance of interest rates on new business vis-à-vis households and non-financial corporations across branches. For the selection and maintenance of the branches all of the requirements laid down in this Guideline apply. The selected branches become notional reporting agents subject to all of the reporting requirements laid down in Annex I of Regulation (EU) No 1072/2013 (ECB/2013/34). This procedure is without prejudice to the obligation of each MFI to which branches belong, to be reporting agents.

5. Minimum national sample size

16. The minimum national sample size is defined differently depending on whether the relevant NCB applies random sampling or selects the largest institutions per stratum.

17. If an NCB applies random sampling in the selection of the actual reporting institutions, the minimum national sample size should be such that the maximum random error for interest rates on new business on average over all instrument categories does not exceed 10 basis points at a confidence level of 90 % ( 18 ).

18. The maximum random error is defined as , with D as the maximum random error, zα/2 as the factor computed from the normal distribution or any suitable distribution according to the structure of the data (e.g. t-distribution) assuming a confidence level 1-α, where is the variance of the estimator of parameter θ, and is the estimated variance of the estimator of parameter θ.

19. If an NCB selects the largest institution per stratum, the sample quality should be based on a synthetic mean absolute error (MAE) measure. The actual synthetic MAE should not exceed a time-varying MAE threshold assuming a 10 basis points error difference in each stratum and indicator.

20. The synthetic MAES for a given estimator in a particular period should be defined as:

with:

as the synthetic MAE

Bc , Bk as the volume in a particular MFI interest rate category

ic 1 as the average interest rate estimated in category c

as the MAE for a given MFI interest rate category on the basis of estimator

Bj 0 as the volume corresponding to the actual non-reporting in a particular stratum j

Bj 1 as the volume corresponding to the actual reporting in a particular stratum j. If sampling is applied Bj 1 refers to the grossed up volumes. The process of grossing up is further described in Section 4

B as the total volume for all strata, i.e. the sum of Bj 0 and Bj 1 across all strata

as the estimation of the total error within a stratum j

ij 1 as the weighted average interest rate corresponding to the actual reporting in a particular stratum j

as the value of the estimator for the take-none sub-stratum of stratum j.

In the event of zero volume coverage in one of the reported strata, the average of the other stratum should be used to avoid a MAE equal to zero.

as the average of the first and third quartiles within the stratum, which are defined as the interest rate reported for the MFI interest rate category for which 25 % (and 75 % respectively) of the reported interest rates are lower than that number. The first and third quartiles are calculated by previously weighting the volume in that category by the institutions in the stratum. The average between the two MAE estimators - the first and the third quartiles - is thereby used as an estimation for the parameter ( 19 ).

21. The maximum random error and the synthetic MAE are separately calculated for new business and outstanding amounts. For new business, the maximum random error and the synthetic MAE should be calculated on the basis of indicators 1 to 11, 13 to 22, and 24 to 29 as described in Appendix 2 to Annex I to Regulation (EU) No 1072/2013 (ECB/2013/34). For outstanding amounts, the maximum random error and the synthetic MAE should be calculated on the basis of indicators 1 to 14 as described in Appendix 1 to Annex I to Regulation (EU) No 1072/2013 (ECB/2013/34).

22. The minimum national sample size refers both to the minimum initial sample and to the minimum sample after maintenance as defined in the next section on maintenance of the sample of the actual reporting population. Due to mergers and leavers, the sample may reduce in size over time until the next maintenance period.

23. NCBs may select more reporting agents than defined as the minimum national sample size, in particular where necessary to increase the representativeness of the national sample in the light of the structure of the national financial system.

24. There needs to be consistency between the number of MFIs in the reference reporting population and the minimum sample size. NCBs may allow MFIs which are resident within a single euro area Member State and individually included in the list of MFIs as established and updated in accordance with the classification principles set out in Section 1 of Part 1 of Annex I to Regulation (EU) 2021/379 (ECB/2021/2) to report MFI interest rate statistics together as a group. The group becomes a notional reporting agent. This means that the group reports MFI interest rate statistics as if it was a single MFI, i.e. it reports one average interest rate per instrument category covering the whole group instead of one rate for each MFI included in the list of MFIs. At the same time, the MFIs within the group are still counted as individual institutio
