Pakistan's foreign exchange reserves stand at $16 billion as the country prepares to repay $3.5 billion to the UAE this month. Saudi Arabia pledged $3 billion in additional deposits and extended its existing $5 billion facility. Pakistan targets $18 billion in reserves by June under an IMF programme. The country previously repaid a $1.43 billion Eurobond in April. Pakistan's central bank reserves face pressure from multiple debt obligations.
