quarter of 2017. growth in 2017 marked the eighth successive year of positive growth in the united states, compared with four consecutive years of positive growth in the euro area. looking ahead, growth in the united states is expected to accelerate on the back of solid growth in investment and consumption and significant fiscal stimulus. at the same time, we have to keep an eye on a gradual increase in long - term interest rates in the united states, given the robust economic growth, an expansive deficit funded fiscal policy, and the federal reserve ’ s exit from the securities markets. this ongoing broad - based economic growth is largely echoed in the june 2018 eurosystem staff 1 / 2 bis central bankers'speeches macroeconomic projections for the euro area. real gdp is projected to increase by 2. 1 % in 2018, 1. 9 % in 2019 and 1. 7 % in 2020. while risks to growth remain broadly balanced, those related to global factors, including the threat of increased protectionism have become more prominent. moreover, the risk of persistently high financial market volatility warrants monitoring. turning to the nominal side, euro area annual inflation, as measured by the harmonised index of consumer prices ( hicp ), increased to an estimated 2 % in june, from 1. 9 % in may. on the basis of current futures prices for oil, headline inflation is expected to remain around the current level for the remainder of the year. measures of underlying inflation remain generally muted, but are higher than the low range that prevailed between mid - 2014 and mid - 2016. developments in domestic pipeline inflation and wages suggest strengthening price pressures. a continued strengthening in domestic cost pressures is expected to be the main driver behind the expected pick - up in underlying inflation towards the end of this year and the further gradual increase over the medium term. this assessment of inflation is broadly in line with the june 2018 eurosystem staff macroeconomic projections for the euro area, which project annual hicp inflation of 1. 7 % in 2018, 2019 and 2020. this outlook depends on keeping the ample degree of monetary policy stimulus in place, as this remains necessary for underlying inflation pressures to continue to build up and be maintained over the medium term. in october 2017, the ecb governing council announced the reduction of its asset purchase programme by half, having announced in december 2016 that it would be scaled back from €80 billion to €60 billion. we gave up our easing bias in the spring and at the june meeting the governing council concluded that

progress towards a sustained adjustment in inflation had been substantial and decided to halve net purchases again and to end them completely in december 2018. with longer - term inflation expectations well anchored, the underlying strength of the euro area economy and the continuing ample degree of monetary accommodation provide grounds to be confident that the sustained convergence of inflation towards our aim will continue in the period ahead, and will be maintained even after a gradual winding - down of our net asset purchases. yet, an ample degree of monetary stimulus remains necessary for underlying inflation pressures to continue to build up and support headline inflation developments over the medium term. looking ahead, monetary policy will be firmly guided by the outlook for price stability and our stance will evolve in a data - dependent and time consistent manner. step - by - step normalisation means that we anticipate the end of the net purchase programme in the short term, while only announcing our expectations with regard to interest rates over the medium term. the difference gives us an appropriate flexibility for our medium - term reaction function, i. e. we do not make any unconditional commitments regarding the long - term future due to the many unknowns and uncertain developments. 2 / 2 bis central bankers'speeches
