Answer:
-$49 billion
Explanation:
The balance on the financial account = capital account balance - current account balance = $1 billion - $50 billion = -$49 billion
The balance of payments (BOP) = current account balance + financial account balance + capital account balance
since BOP is always $0, then:
capital account balance = current account balance + financial account balance
$1 billion = $50 billion - $49 billion
