Apply the DD-AA-XX model to explain the correlation in the left graph between fiscal balance and current account balance.

6. According to the 2019 IMF External Sector Report (ESR), the decline and reconfiguration of current account balances over the past decade reflect a combination of macroeconomic policies and terms-of- trade effects. Fiscal policy and credit conditions have been key drivers of current account dynamics since the crisis, such that economies with tight (easy) fiscal policies and credit contractions (expansions) have generally experienced an increase (decline) in their current account balances. The graphs below present some data evidence for the role of fiscal and credit policy driving the current account. 1. Selected Economies: Change in Current Account Balance vs. 2.
