* Yen up 1.25 pct against dlr on lack of new BOJ action
* Lack of action sends shares, risky European debt lower
* Oil, copper pressured by prospect of weaker Chinese demand
By Richard Hubbard
LONDON, June 11 The yen jumped against the
dollar, world shares fell and yields on riskier European debt
rose on Tuesday after the Bank of Japan disappointed investors
by deciding against moving to calm volatile markets.
The decision unnerved investors already highly sensitive to
any signs of a lack of commitment from global central banks to
the ultra-loose monetary policies that have fuelled rapid gains
in asset prices this year.
Traders said some nervousness over a German Constitutional
Court hearing on the legality of the European Central Bank's
bond-buying scheme could also be prompting investors to cut
their exposure to lower-rated euro zone debt.
The BOJ's decision not to follow up its $1.4 trillion
stimulus programme announced in April at its latest policy
meeting with measures to ensure bonds yields stayed low rattled
mainly foreign investors who had expected further action.
"There were some expectations that the BOJ would curb bond
market volatility and that has not happened," said Chris Walker,
currency strategist at Barclays.
The dollar sank by around 1.25 percent to 97.50 yen
against the a resurgent Japanese currency by mid-morning, while
the euro lost over 1 percent at 129.55 yen.
Some in the market accused the BOJ of poor communication.
"Many of the signals coming out of the BOJ recently have
confused the markets, exacerbating volatility in bonds and
hurting share markets," said Mike Ingram, market analyst at BGC
Disappointment over the BOJ rippled through other riskier
asset markets, sending European shares lower and yields on
weaker euro zone debt higher.
The broad FTSE Eurofirst 300 index of top shares,
which has shed 5 percent in the past 12 trading sessions, had
lost a further 0.9 percent by mid-morning.
"Given the lack of action from Japan overnight, that just
serves to highlight how the markets are highly dependent on
central banks," said Ioan Smith, strategist at Knight Capital.
Earlier the BOJ's decision pushed Japan's Nikkei index down
1.5 percent while MSCI's broadest index of Asia-Pacific
shares outside Japan tumbled 1.1 percent to hit
fresh 6-1/2-month lows.
The MSCI world equity index fell 0.2
percent, reversing three days of gains.
In the debt market investors pulled out of the riskiest
assets sending Greek 10-year bond yields up 75
basis points at 10.22 percent. Portuguese equivalent bonds rose
34 bps to 6.59 percent.
The Greek government has failed to find buyers for the
state-owned natural gas company, threatening the privatisation
goal set under the country's bailout.
The selloff across the peripheral markets supported the
euro, which was unchanged against the dollar at $1.3265
as investors retreated into cash.
In commodity markets, concerns over slower growth in top
consumer China added to the worries over central bank policies.
Brent crude traded around 39 cents lower at $103.60 a barrel
, while copper was near a one-month low at $7,114.50 a
