UPDATE 1-German business morale unexpectedly rises in May despite Ukraine war

* Rise bucks expectations for a small fall

* Ifo sees "no observable signs of a recession" (Adds detail)

BERLIN, May 23 (Reuters) - German business morale rose unexpectedly in May, as Europe's largest economy showed resilience in the face of high inflation, supply chain problems and the war in Ukraine, a survey showed on Monday.

The Ifo institute said its business climax index rose to 93.0 in May following a reading of 91.9 in April, revised up slightly from 91.8.

A Reuters poll of analysts had pointed to a May reading of 91.4.

Ifo said in its statement it currently saw "no observable signs of a recession".

Data released last Friday showed German producer prices saw their highest-ever annual rise in April -- surging 33.5% on the year -- as the Ukraine war sends the cost of energy spiralling for German industry.

German Finance Minister Christian Lindner, hosting a meeting of the Group of Seven economic powers last week, said inflation needed to get back to 2% quickly and that central banks had a "great responsibility" to help get it under control in the G7.
