MUNICH - The trade conflict between the United States and China is the main source of uncertainty for the German economy, an economist at Ifo said on Monday after the institute's survey showed business morale deteriorating in June.

Britain's expected departure from the European Union and rising tensions between Iran and the United States are not main sources of uncertainty, Ifo economist Klaus Wohlrabe said.

He added that tensions with Iran could have an impact in the case of a major escalation or if the oil price rises significantly.

Wohlrabe said he did not expect the German economy to plunge into recession.
