Luxembourg late-payment interest rate
Statutory interest for late payment in commercial transactions under EU Directive 2011/7/EU: the ECB main refinancing rate in force on the first day of the calendar half-year, plus 8 percentage points. Derived live from this country's ecb-main-refinancing-rate series; fixed for the half-year, so it can differ from today's live MRO.

What this value means
EU-harmonised statutory interest for late payment in commercial transactions = ECB main refinancing rate (snapshotted on 1 January / 1 July) + 8 percentage points (Directive 2011/7/EU, art. 2). This is the Directive MINIMUM and the figure the European Commission publishes per member state; national transposition may set a HIGHER rate for some transaction types. Because it is a half-yearly snapshot, the value tracks the MRO as of the half-year start, not today's live MRO. Derived live from this country's ecb-main-refinancing-rate series. Implemented in Luxembourg by the loi du 18 avril 2004 relative aux délais de paiement et aux intérêts de retard as amended in 2013, at the euro-area default of the ECB main refinancing rate plus 8 percentage points - 10.15% for H1 2026 and 10.40% for H2 2026. TIMING TRAP: the ECB's 17 June 2026 increase landed 13 days before the 1 July fixing date, so H2 picks it up in full while H1 computations must still use 10.15%; a single annual figure for 2026 would be wrong for half the year. Luxembourg's separate taux d'intérêt légal, set by annual règlement grand-ducal, is a different series and is not carried here.
