LONDON, June 23 (Reuters) - The euro held steady on Wednesday but remained vulnerable as a recent risk rally appeared to have run its course and on concerns about the euro zone banking system.
A sharp fall in U.S. stocks <.SPX> the previous day and a subsequent drop in the Nikkei <
> helped support the dollar and the yen, which are favoured when risk aversion spikes and doubts over the health of the global economy emerge.European shares last traded down 0.3 percent <
>."With advanced economies tightening their fiscal policies, the risks of economic slowdown are rising," said Lee Hardman, currency economist at Bank of Tokyo-Mitsubishi UFJ.
By 1110 GMT, the euro was up 0.1 percent from late U.S. trading on Tuesday at $1.2281 <EUR=>, having dipped to $1.2244.
Technical analysts were looking for a daily close under $1.2255. That level marks a 38.2 percent Fibonacci retracement of the euro's recent rally from its four-year low of $1.1876 hit in early June on trading platform EBS to a one-month high of $1.2490 marked on Monday.
Reaction was muted to the euro zone purchasing managers' survey, where the composite index dipped to 56.0 in June from 56.4 the previous month. [

The dollar index, which measures the dollar's value against a basket of currencies, was down 0.2 percent at 85.950 <.DXY>, but up from a one-month low of 85.091 marked on Monday.
Against the yen, the dollar fell 0.3 percent to 90.20 yen <JPY=>, its lowest level since May 27.
STERLING UP
Sterling extended gains after minutes from the Bank of England's June meeting showed an unexpected split, with Monetary Policy Committee member Andrew Sentance voting for a 25 basis point rate increase. [

"It's clearly very surprising, someone voting for a hike. Sentance however has never made any secret of being on the hawkish side on inflation," said Alan Clarke, economist at BNP Paribas. "I don't think it will lead to a hike."
Meanwhile, the Swiss franc held gains, hovering near an earlier all-time high against the euro of 1.3585 francs on trading platform EBS earlier. Traders said option barriers were in place at 1.3575, 1.3550 and 1.3500 with large stops lurking below.
The Australian dollar was steady at $0.8725 <AUD=D4>, unfazed by media reports that Australian Prime Minister Kevin Rudd faces a possible leadership challenge.[
