HONG KONG, April 29 (Reuters) - Asia stocks and the Australian dollar bounced back on Wednesday from a two-day slide, with investors taking heart from data showing the U.S. economy slowly healing, and betting the swine flu outbreak will be contained.
The yen slid against higher-yielding currencies on improving risk appetite after data showing U.S. consumer confidence posting its biggest monthly jump in three years and the pace of home price declines slowing from a record pace. [
]The signs of gradual recovery in the struggling U.S. economy helped ease some of the worries about the impact of the swine flu, as well as reports that top U.S. banks will need to raise more capital after the government stress tests.
But investors were still on high alert over the risk of swine flu being declared a pandemic and the potential economic damage.
A global hunt turned up new infections all around the world, and frightened governments warned people to stay away from Mexico, where up to 159 people have died.
The number of infections in the United States rose to 65 [
], Canada has 13 [ ] and new cases were also confirmed in Israel and New Zealand.But global health officials cautioned that the numbers meant little in a rapidly changing situation, with doctors and clinics rushing to test people with respiratory symptoms and no one sure just how far the virus had spread.
Seoul's KOSPI index <
> climbed 1.7 percent, led by shares of technology companies like Samsung <005930.KS> and LG Electronics <066570.KS>, and banks.Analysts were still cautious about how much further shares could rise given the still severe troubles gripping the global economy.
"In order for the index to make a meaningful rebound, we need clearer signs that the global economy and corporate earnings will pick up by 2010, but we haven't seen those yet," said Choi Seong-lak, a market analyst at SK Securities in Seoul.
The MSCI index of Asia-Pacific shares outside Japan <.MIAPJ0000PUS> was up about 1.7 percent in morning trade.
Trading was limited due to a holiday in Japan, which begins its Golden Week string of holidays that continue next Monday through Wednesday. Many markets in Asia and around the world will also be closed on Friday for May 1 holidays.
AUSSIE JUMPS, NZ SWAP RATES DOWN
The Australian dollar -- still among the most sensitive currencies to shifts in risk appetite due to its relatively high yield -- jumped 1.1 percent to $0.7135 <AUD=D4> and gained 1.6 percent against the yen <AUDJPY=R>.
Traders said some short-term speculators were covering short positions in Aussie/yen and other yen cross currencies, which tend to move in line with stocks, that were taken on news of the swine flu outbreak at the start of the week.
The dollar climbed 0.6 percent to 96.95 yen <JPY=>, while the euro was up 1 percent to 127.85 yen <EURJPY=R>.
As stock markets around the world rallied about 30 percent from their early March lows, market players also favoured traditional carry trade players in currencies -- borrowing cheap funds in low-yielding currencies such as the yen to buy higher-yielding ones.
In New Zealand, rates on interest-rate swaps <NZDIRS> fell further, a day before the Reserve Bank of New Zealand <NZCASH=RBNZ> is expected to cut rates by a half-point to a record low 2.5 percent at a policy meeting. [
]One-year swap rates fell 10 basis pints to 2.955 percent and were just 14 basis points above a record low hit in early March. Five-year swap rates were down about 10 basis points as well to 4.655 percent and were down 43 basis points from a four-month peak hit earlier in the month.
