Lebanese GDP could fall by a quarter in 2020 under the combined effect of the deep economic crisis that has taken place since 2019 and the Beirut port explosion. In the short term, hopes of a recovery are limited. The economic system that closely links the public finances, commercial banks and the central bank appears to be on its last legs. The system of multiple exchange rates will not prevent the exhaustion of foreign currency reserves in the near future. Meanwhile, the government, which is in default on its foreign currency debt, has been forced to monetize its fiscal deficit. Commercial banks have built up record exposure to sovereign debt and substantial external liabilities.
