BERLIN, Aug 24 (Reuters) - The German economy grew more than expected in the second quarter as the easing of COVID-19 curbs spurred consumers to dip into record savings piled up during the winter lockdown and the state pressed on with a huge debt-financed stimulus push. Gross domestic product grew an adjusted 1.6% on the quarter, the Federal Statistic Office said on Tuesday, up from its previous estimate of 1.5% and following a revised first quarter contraction of 2%. On the year, Europe"s largest economy expanded by a calendar-adjusted 9.4% in the second quarter, leaving economic activity 3.3% below the pre-crisis levels of the fourth quarter of 2019. Private consumption grew by 3.2% between April and June, contributing 1.6% percentage points to overall growth and pushing the savings rate down to 16.3%. In the first quarter, when shops, bars and restaurants were closed under Germany"s lockdown, that rate hit a record high of 22%. Public consumption expanded 1.8%, contributing 0.4% to the overall growth rate.State spending to cushion the impact of the coronavirus crisis, financed with unprecedented new borrowing, blew a 80.9 billion euro ($95 billion) hole in the public finances in the first half of the year, the statistics office said. This equated to a public sector deficit of 4.7% of GDP, the largest in 26 years and what Carsten Brzeski from ING Bank termed "the downside of the rapid economic recovery." The stimlus should help lift the economy back to pre-crisis levels before the end of 2021 but will leave the government that emerges from next month"s federal election with a heavy burden to shoulder, Brzeski said.Germany"s quarter-on-quarter GDP growth compared with a second quarter euro zone average of 2% and growth of 0.9%, 2.7% and 2.8% respectively the bloc"s next biggest economies, France, Italy and Spain.
