May 11 (Reuters) - Australian shares fell for a fourth straight day on Wednesday, with mining and gold stocks leading the declines, as caution around U.S. inflation data amid risks of sharp interest-rate hikes and a global recession weighed on equities.

The S&P/ASX 200 index slid 0.5% to 7,018.80 by 0035 GMT, after having ended 1% lower on Tuesday.

Markets have been volatile across asset classes as a combination of surging inflation and fears that monetary tightening aimed to tame inflation would slow down global economic growth.

In Asia, Japan's Nikkei shed 0.36% and S&P 500 E-minis futures were up just 0.06%.

Domestic gold stocks dropped 2% and marked a fourth consecutive losing session.

Sector major Newcrest Mining fell 2.4%.

Bullion prices fell overnight as the dollar resumed strengthening and cautious investors shifted focus to the U.S. inflation data due later in the day.

Miners, too, were down for a fourth straight session as they tracked iron ore and base metal prices lower, to slump 1.4%.

Sector heavyweights BHP Group and Rio Tinto declined 1.2% and 0.2% respectively.

Iron ore prices fell on Tuesday as the demand outlook was pressured by COVID-19 lockdowns in China.

Energy stocks retreated 0.7% as oil prices slumped, while financials lost 0.5%.

Bucking the trend, healthcare stocks rose 1% and were the only gainers on the benchmark.

Agribusiness firm Graincorp Ltd fell 2.6% amid a weak broader market, even as it reported around five-fold jump in first-half profit.

In New Zealand, the benchmark S&P/NZX 50 index was up 0.2% at 11,256.12. (Reporting by Himanshi Akhand in Bengaluru; editing by Uttaresh.V)
