MUMBAI, Sept 1 (Reuters) - Long-dated euro zone bond

yields climbed on Monday with Germany's 30-year yield hitting a

14-year peak, tracking a rise in U.S. Treasury yields, as

investors continue to fret over government debt levels around

the world.

Germany's 30-year yield rose 3 basis points to

3.378%, its highest since August 2011. Other long-dated euro

zone yields, including in France and the Netherlands, traded

broadly in line with Germany's and were also at 14-year highs.

Long-tenor euro zone bond yields posted their biggest

monthly jump in five months in August as long-dated debt

remained under pressure across developed economies. The 30-year

U.S. Treasury yield rose 4 bps on Friday.

U.S. markets are closed on Monday for the Labor Day

holiday.

Germany's 10-year yield, the benchmark for euro zone bonds,

was up 2 bps at 2.75%.

In addition to fiscal worries, political developments in

France have also been a drag for the country's government bonds.

The 10-year French government bond yield was last up

2 basis points at 3.53%.

The developments have also contributed to a widening of the

spread between German and French 10-year bond yields

, which was last 78 basis points after last week

reaching its widest since April.

European Central Bank President Christine Lagarde said on

Monday she was looking very attentively at the French bond

spreads but that France was not currently in a situation that

would require IMF intervention.
