WHENWhen initializing banks from EBA_2018.csv

ACTIONCreate exactly 48 bank agents matching the NBANKS constant

CONSEQUENCEModel systemic risk calculations will be incorrect if fewer or more than 48 banks are created, as the get_extent_of_systemic_event function divides by NBANKS=48 and the balance sheet aggregation will not match EBA 2018 reported values

WHENWhen creating the AssetMarket during initialization

ACTIONInitialize asset prices to exactly 1.0 for each asset types using defaultdict

CONSEQUENCEInitial price of 1.0 is required for consistent price impact calculations using Cifuentes 2005 formula. If prices differ, the initial shock magnitude and contagion dynamics will be miscalibrated

WHENWhen calculating bank balance sheet values from EBA data

ACTIONVerify each parsed CSV values convert to valid floats without errors

CONSEQUENCECSV parsing with float() on unvalidated strings will raise ValueError at runtime, causing the entire model to crash before any simulation can run
