INTERVIEW-Germany's Schaeuble says debt reduction is global task

* No sustainable growth without debt reduction

* USA and Japan also need fiscal consolidation

* Sees no risk of delay with Basel III banking rules

* Schaeuble goes to G20 finance ministers talks in Mexico

BERLIN, Nov 2 (Reuters) - The United States and Japan must

share responsibility with Europe for ensuring global economic

stability, German Finance Minister Wolfgang Schaeuble said,

signalling that a G20 meeting this weekend should not focus

solely on the euro zone crisis.

Speaking in an interview before finance ministers and

central bankers from the Group of 20 nations meet in Mexico, he

said top economies must pursue structural reforms and fiscal

consolidation to win back market trust and build sustainable

growth.

Schaeuble also said in emailed answers to questions

submitted by Reuters that he saw no danger of delay in the

introduction of Basel III rules on banking capital that are due

to be phased in from January.

Schaeuble does not want the two-day G20 meeting in Mexico

City to concentrate exclusively on the euro zone crisis to the

detriment of other urgent issues such as the "fiscal cliff"

facing the United States and Japan's debt problems.

"The United States and Japan bear as great a responsibility

for (ensuring stability) as we Europeans," he said.

"The G20 economies must decisively win back confidence with

structural reforms and sustainable financial policies. This is

the most important precondition for strengthening global

economic conditions," Schaeuble said.

"Without consolidation and reforms we risk further loss of

confidence and still less growth. No sustainable growth can be

built on a mountain of debt," said the minister, known for his

advocacy of fiscal rigour even in times of recession.

In the United States, existing legislation will raise taxes

and cut spending to the tune of about $600 billion in 2013

unless lawmakers take action. However, Republicans and Democrats

have yet to agree on measures to avoid this "fiscal cliff",

which could cause the economy to contract.

The G20, which brings together major wealthy and emerging

economies, must measure its progress by the goals it set at its

Toronto summit two years ago, he added. There the developed

countries committed to halve their budget deficits by 2013 and

to stabilise their debt load by 2015.

HOPEFUL ON SPAIN, FIRM ON GREECE

Schaeuble has taken a tough line on Greece and other weaker

members of the euro zone during the region's three-year

sovereign debt crisis, insisting they swallow austerity medicine

even as their economies sink deeper into recession.

But he had warm words for Spain, saying it was on the "right

path" and that there were signs - seen for example in falling

wage costs and in the current account - that its economic

imbalances were improving.

Schaeuble reiterated that Greece, still locked in difficult

talks with its international creditors aimed at averting

bankruptcy, must implement the tough measures it has promised.

The minister dampened expectations that the euro zone's new

bailout fund, the European Stability Mechanism (ESM), might soon

be able to recapitalise banks directly, reiterating that a

planned new oversight body must first be fully functional.

"It is important that liability and control go hand-in-hand.

In other words, quality clearly comes before speed," he said.

Schaeuble said he did not fear delays in implementation of

the Basel III rules or the possibility that the United States

and Britain - which have both criticised them as too unwieldy to

work - might not adopt them.

Basel III is the world's regulatory response to the

financial crisis, forcing banks to triple the amount of basic

capital they hold in a bid to avoid future taxpayer bailouts.

"Like other international financial market reforms, Basel

III and its implementation in the most important global

financial centres are subject to an internationally-agreed

regime of checking procedures," he said.

The G20's regulatory arm, the Financial Stability Board

(FSB), will complete proposals by the time of the group's next

summit in September 2013 on regulation of non-bank financial

institutions ranging from hedge funds to insurance companies.

"We welcome the broad international consensus on a strict

regulation of money market funds which act very similarly to

banks," Schaeuble said.
