* Nikkei futures, Australian stock futures down after Wall St fall
* Bernanke confirms market fears of a stimulus withdrawal this year
* Dollar higher as U.S. Treasury yields jump

SYDNEY, June 20 (Reuters) - Asian stock markets were braced for a fall on Thursday in line with Wall Street after the U.S. central bank confirmed that it would begin to withdraw stimulus this year if the economy continued to recover as it expected.
Tokyo’s Nikkei futures in Chicago and Australia’s share price index futures fell, pointing to weaker openings for two of Asia-Pacific’s main markets, following a 1.4 percent slide in the U.S. S&P 500 index.
Traders said markets could come under even more pressure if a report on China’s factory activity, due at 0145 GMT, provided fresh evidence of weakness in Asia’s economic powerhouse.
“Given the market’s growing fears over a hard landing for the Chinese economy, a particularly weak number could add to the post-FOMC selling pressure on the emerging currencies as well as the commodity bloc currencies,” analysts at BNP Paribas wrote in a note.
On Wednesday, MSCI’s broadest index of Asia-Pacific shares outside Japan had ended flat with investors unsure of what Federal Reserve chief Ben Bernanke would say and how markets would react.
Dashing hopes for a more dovish stance, Bernanke said the U.S. economy was expanding strongly enough for the central bank to begin slowing the pace of its bond-buying stimulus later this year.
That sent U.S. stocks and bonds sharply lower, pushing benchmark Treasury yields to a 15-month high. In turn, the U.S. dollar rallied 0.9 percent against a basket of major currencies , posting its best one-day gain in over a month.
The euro slid around 0.8 percent to $1.3262, swiftly retreating from a four-month high around $1.3418.
Among the hardest hit were the Australian dollar, which has been sold not only as a commodity currency but also as a proxy for emerging markets. Emerging market currencies, from Indonesia to Thailand, are also expected to come under heavy pressure
The Australian dollar slumped more than 2 percent, breaking below $0.9300 for the first time since September 2010.
