During the month of July 2019, banks' own liquidity deteriorated by 69.3 billion, mainly due to the decline in the balance of operations with the State and other net factors (-215.4 billion). The information is given by the Bceao through its "Monthly note of economic situation in the WAEMU countries at the end of July 2019". According to the document, this situation was mitigated by resource inflows from outside (+141.6 billion). "With the deterioration of their own cash flow, banks increased their commitments on bceao counters by 145.9 billion, after an increase of 39.0 billion the previous month. This situation is mainly attributable to the commitments of some banks on the weekly window (+230.0 billion), mitigated by a disengagement of 84.1 billion on the marginal loan compartment, "informs the same source. It adds that the analysis of the implementation of the minimum reserve system, at the end of the maintenance period due on 15 June 2019, shows a surplus situation for EU banks in relation to the required reserves. Banks' free reserves, valued over the period, stood at 858.7 billion, or 123.9% of the required reserves, down 12.1 percentage points from May 2019.
