* Oil prices down this week, but credit concerns resurface
* G8 comments on dollar eyed

TOKYO, July 8 (Reuters) - The dollar inched up against the euro on Tuesday, supported by a sharp drop in oil prices this week, even as investors fretted about a further deterioration in the financial system's health.
Credit concerns resurfaced on Monday after a Lehman Brothers report said a pending accounting change could force Fannie Mae <FNM.N> and Freddie Mac <FRE.N>, the two largest U.S. mortgage funders, to raise a combined $75 billion in capital at a difficult time. [
]The report on Fannie Mae and Freddie Mac drove Wall Street shares down and squashed a dollar rebound spurred after oil slid over $4 a barrel on Monday.
Hideki Amikura, deputy general manager at Nomura Trust and Banking, said the dollar's resilience despite the dire capital situation of Fannie Mae and Freddie Mac could reflect market hopes for a government bail-out.
"Despite the seriousness of the issue, the market remains calm, suggesting there may be expectations of the use of public funding to support these institutions," he said, adding that the dollar was likely to stay in a 106-108 yen range this month.
Market players were keeping an eye on oil for the dollar's near-term direction. Oil was up about $1 on Tuesday near $142 a barrel <CLc1>, recovering only part of Monday's fall but off the record $145.85 hit last week. [
]The euro edged down 0.2 percent to $1.5698 after falling to a low of $1.5679, well off the intraday high of $1.5735.
The dollar dipped 0.2 percent to 106.92 yen <JPY=> after seesawing between 106.66 yen and 107.75 yen on Monday.
A 2.5 percent fall in Tokyo's Nikkei average <
> helped support the yen. The low-yielding currency tends to benefit when equity markets falter as investors trim positions in carry trades by selling higher-yielding currencies.But with carry trades not nearly as widespread as they were before the credit crisis broke last year, the yen's gains during such bouts of risk aversion have been limited.
The euro fell 0.6 percent to 167.86 yen <EURJPY=R>. The Australian dollar <AUDJPY=R> and New Zealand dollar <NZDJPY=R>, both recipients of carry-trade funds, both dropped about 0.4 percent.
The dollar index, which tracks the currency's performance against a basket of six currencies, was up 0.1 percent at 72.76 <.DXY>.
G8 TO MENTION DOLLAR?
Market players were watching the annual summit of the Group of Eight industrialised nations for any comments on the dollar's weakness.
German Chancellor Angela Merkel pressed other leaders for language on exchange rates in the economic communique, a G8 diplomat tolds Reuters.
U.S. President George W. Bush reaffirmed at the summit that he supported a strong dollar, a U.S. official told reporters.
Earlier a Japanese official said there was no specific discussion about currency market moves at the session on the economy. [
]The euro has dropped about 2 U.S. cents since late last week on diminishing expectations that the European Central Bank would boost interest rates again later in the year, traders said.
"There was disappointment that the ECB said it had no bias for its monetary policy, as some players had bet on a more hawkish tone to keep alive prospects of more rate hikes," said a senior dealer at a Japanese trading house.
The ECB raised its benchmark rate to 4.25 percent from 4 percent last week to bring inflation under control. But it then said it had no bias as regards its policy outlook, suggesting it was unlikely to tighten again soon.
Amikura at Nomura Trust and Banking said the drop in oil prices may also have prompted short-term players to take profits on the euro.
