ZURICH--Switzerland's economic growth was steady in the fourth quarter, underpinned by robust private and public spending, data released Tuesday showed.

Gross domestic product in the three months through December rose 0.6% from the previous quarter and 1.9% on the year, the State Secretariat for Economic Affairs said. The result was above economists' expectations for a quarterly gain of 0.4% and an on-year expansion of 1.8%.

In the third quarter, the economy expanded 0.7% on-quarter and 1.9% on-year, the economics department said. Growth for the full year edged up to 2.0%, from 1.9% in 2013.

The main drivers of Swiss fourth quarter growth were private consumption, which rose 0.3% and government spending, which increased 1.9%, it said.

Swiss goods exports slipped 1.0% on-quarter, with higher sales of railroad vehicles failing to offset a decline in chemicals, pharmaceuticals and machinery products.

The Swiss economy again outperformed its key export market, the European Union, which posted quarterly growth of 0.4% and annual expansion of 1.3% in the fourth quarter.

This scenario however is likely to change this year after the Swiss National Bank's abandoning of its 3 1/2-year policy of capping the franc at 1.20 per euro, which helped Swiss exporters to the EU keep their prices down.

The economics department--which had projected Swiss GDP to grow 2.1% this year before the SNB decision, will update its GDP, inflation and unemployment forecasts on March 19, as will the Swiss central bank.
