NEW YORK, Jan 27 (Reuters) - The euro hit two-month highs on Thursday against the U.S. dollar and yen after a credit rating downgrade for debt-ridden Japan and more hawkish policy talk in Europe, while global share prices edged higher.
Wall Street stock indexes held near 29-month highs as strong results from heavy equipment maker Caterpillar Inc <CAT.N> counterbalanced a surprising rise to 454,000 in new claims for weekly U.S. jobless benefits, the highest level since late October. For details, see [
]Standard & Poor's surprised markets by downgrading Japan's long-term sovereign debt one notch from AA to AA minus, citing the country's ballooning deficit, which it said will further reduce Tokyo's already restricted fiscal flexibility.
The move will have a limited impact on Japan's ability to raise money on financial markets, but it raised a red flag with investors about other leading countries' fiscal imbalances.
"It is not a big a deal as a downgrade of a major European country or the U.S. as most of Japan's debt is financed internally, but still, it's a big story," said Omer Esiner, chief market analyst at Commonwealth Foreign Exchange in Washington.
Among the Group of Seven industrial countries, the United States, Britain, Italy and France are all carrying large deficits. Only Germany is looking sound and even it felt an impact as the cost of insuring its debt against default over five years hit its highest since March 2009.
Commodity prices were mostly lower as the prospect of rising interest rates in Europe grew after European Central Bank member Lorenzo Bini Smaghi said an expected rise in imported goods inflation could not be ignored. [
]"The ECB has started to show more concern about secondary price pressures, and the market has acknowledged that," said Gavin Friend, currency strategist at nabCapital.
The euro rose 0.13 percent at $1.3715 <EUR=>, off the earlier two-month high of $1.3759, while it traded up 1 percent against the yen at 113.76 <EURJPY=>.
Bini Smaghi's comments went to the heart of current investor concerns, highlighting the potential for inflation to prompt central banks to raise interest rates at a time when low rates are seen as key to boosting renewed economic growth.
His comments also further highlighted a policy divergence with the United States, which on Wednesday left in place rock-bottom interest rates and gave no indication of backing away from its loose policies. [
