Goldman Sachs has bought forward a claim against Bahrain’s TIBC whose default 10 years ago triggered the biggest financial crisis in Saudi Arabia. The Bahraini lender raised money in international markets, transferring the funds to now defaulted Saudi conglomerate Ahmad Hamad Algosaibi and Brothers (AHAB). After TIBC defaulted on a foreign exchange deal, AHAB collapsed along with another Saudi conglomerate Saad Group, leaving an estimated $22 billion in unpaid debts. TIBC, administered by the Central Bank of Bahrain, has a claim of around $3 billion against AHAB, while more than 60 banks that have lent money to TIBC remain unpaid.
