* Euro under pressure on banking sector worries
* RBA keeps rates steady, gives no clues for future
* China May PMI slips from April, near forecast

TOKYO, June 1 (Reuters) - The euro and the Australian dollar fell on Tuesday as investors remained keen to cut risk, but the Aussie trimmed losses after comments from the Australian central bank were neutral on monetary policy rather than dovish as some had expected.
The euro fell back towards a four-year trough against the dollar marked last month, under pressure as worries mount that the region's sovereign debt problems may spread to the banking system.
The European Central Bank on Monday warned that euro zone banks faced up to 195 billion euros in a "second wave" of potential loan losses over the next 18 months due to the financial crisis, and said it had increased purchases of euro-zone government bonds. See [
].The Australian dollar was knocked lower after approvals for building new Australian homes dived in April, backing bets the Reserve Bank of Australia (RBA) would not raise interest rates anytime soon. [
] [ ].The RBA kept rates on hold at 4.5 percent as expected but traders who were watching for hints that it might hold rates steady for the coming months, only got a central bank statement saying that its policy was appropriate for the near term. [
] [ ]That helped the Aussie pare losses. The Australian dollar was 0.7 percent lower at $0.8398 <AUD=D4> after falling as far as $0.8354. Against the yen, it dropped 1 percent to 76.47 yen <AUDJPY=R> after sliding at one point to 76.05 yen.
"Economic fundamentals in Australia are not so negative but the impact from Europe, worries that the pace of China's economic growth may slow, and weakness in stocks are all weighing on the Aussie," said Tomohiro Nishida, treasury department manager at Chuo Mitsui Trust and Banking.
The euro <EUR=> fell 0.3 percent to $1.2273, hovering above a four-year low of $1.2143 struck on May 19. Near-term support is seen around $1.2140, the 50 percent Fibonacci retracement of the currency's 2000-08 advance.
"Over the next 18 months calm water could turn turbulent in the blink of an eye," RBC Capital senior currency analyst David Watt wrote in a note.
"Accordingly, euro rallies seem likely to remain rather shallow and in that regard it is struggling to maintain the $1.23 handle."
Traders said investors were looking at every bounce in the single currency to sell. Against the yen, the euro slipped 0.1 percent to 111.93 yen <EURJPY=R>.
Speculators and funds have gone short on the euro in droves in recent months with the latest data from the Commodity Futures Trading Commission suggesting they were still wary of cutting those positions.
Eyes are on the G20 meeting of finance officials and central bankers in South Korea later this week, with investors keen for reassurance that the euro zone debt problems are being dealt with. [

But the dollar index <.DXY> edged up 0.1 percent to 86.67, supported by safe-haven inflows amid growing worries about the sustainability of a global recovery.
Underlining those economic risks, China warned on Monday that global growth remained vulnerable to sovereign debt risks and the possibility of a second downturn. [
]Data showed on Tuesday China's official purchasing managers' index (PMI) fell to 53.9 in May from 55.7 in April. The reading was in line with the median forecast and marked the 15th straight month that the PMI has stood above the threshold of 50 that demarcates expansion from contraction. [
]In Japan, Tokyo market players were split on how much impact political woes for Prime Minister Yukio Hatoyama would have on the yen and other assets.
Hatoyama said on Tuesday that he would stay on in his post, media reported, despite pressure from within his own party to resign as his approval ratings slide ahead of an upper house election. [
]"A change in leadership won't end Japan's political confusion. The yen is likely to weaken just as political confusion in Britain has recently hit sterling," said Koji Fukaya, senior FX strategist at Deutsche Securities.
Cross/yen was also hurt after news that Argentina extended the deadline for its debt swap by two weeks on Monday. [
