47. Monetary. In fulfilling its main task - to promote price stability -, the National Bank of Angola took into account the continuous implementation of the current Operational Framework for Monetary Policy (QOPM), in the sense of migrating to a System of Inflation Targets. 48. With the QOPM, the BNA Rate and the interest rates of Permanent Lending and Liquidity Absorption Facilities became the main instruments of monetary policy, having M2 as an intermediate variable, for the conduct of the same, with the objective of to reach the inflation defined by the Executive (thus giving a flexible character to the introduction of the inflation targeting system). 49. In this context, the M2 projections take into account the inflation targets defined for the five-year period 2013-2017, as well as the perspective of Public Expenditure and economic growth. 50. Consideration was also given to the continuous introduction of macro-prudential regulation, with a sense of convergence to international norms and standards, of a preventive nature to the risks of financial stability supported by strong and rigorous supervision. 51. Bearing in mind the above elements, the monetary sector projections adopted the following assumptions: a. The deceleration of inflation in the first two years, followed by a certain stability, with 7% being the highest level of this indicator, over the last 3 years of the year; B. The growth of Means of Payment, induced by the entry into force of the new Exchange Regime for the oil sector, in 2013, with the prospect of a stabilization effect of its effect in the following periods;. Oil production profile and GDP growth trajectory; and d. The profile of Public Expenses. 52. External. Bearing in mind the risks inherent to the performance of the world economy and the need to guarantee the execution of the expenditure established in the Fiscal Framework, the estimates of the Balance of Payments for the six-year period 2012-2017 had the following assumptions: a) CURRENT ACCOUNT. It is estimated that the account will show decreasing results, with a surplus, from 2012 to 2015, and a deficit, in 2016 and 2017. In order to obtain these results, the calculation of revenues with an increasing behavior contributed, as a result of the strong growth in volumes exports of oil and diamonds, despite the reduction in the prices of these products, as well as the estimates of gas exports from the Angola LNG project.
