By Jan Strupczewski

BRUSSELS, May 30 (Reuters) - The EU executive will suggest on Wednesday the euro zone might need to issue collective debt and run a joint budget, among proposals for bolstering the single currency that echo ideas from new French President Emmanuel Macron.

People familiar with the European Commission reflection paper told Reuters the scenario of a finance minister managing common revenue, spending and borrowing had been worked on for many months in Brussels, but now appears a much more likely option since centrist former banker Macron won power on May 7.

German conservatives dislike an idea they say means paying for poorer neighbours. But Chancellor Angela Merkel, seeking re-election in September, has welcomed Macron's victory and EU officials said they hoped governments might start working on a plan to forge a more cohesive euro zone from next year.

The Commission paper examines possible reforms to the bloc after the 2010-2012 sovereign debt crisis that nearly destroyed it and which triggered a wave of quick fixes for its weak spots.

While some problems have been addressed, there is a lot more EU governments need to do to have an optimally functioning Economic and Monetary Union (EMU), the Commission will say.

The document, part of a wider series on the future of the European Union, comes as the EU is to start talks with Britain on the terms of its withdrawal - a great setback to European integration but one that will see the euro zone make up nearly four-fifths of the EU's economy, up from two thirds today.

NO BLUEPRINT, JUST IDEAS

The Commission will avoid making any clear suggestions as to the evolution of the single currency area, leaving it up to EU governments to decide which of the ideas they like.

But it does say that in the later stages of deepening euro zone integration, not least because it would require politically difficult and time-consuming changes to EU treaties, the bloc could establish a euro zone treasury.

The chairman of euro zone finance ministers, the Eurogroup, could be in charge of such a new institution, the Commission will say. But it will also note that the job of Eurogroup president itself could be integrated into the Commission.

The treasury could manage what the Commission calls a "macroeconomic stabilisation function" - EU jargon for a euro zone budget to mitigate economic shocks, for instance used to support investment, which is the first victim of a downturn.
