Asian indexes were pressured in Friday trade after the dollar firmed overnight and as investors looked ahead to more corporate earnings due during the session.

Japan's Nikkei 225 (Nihon Keizai Shinbun: .N225) slid 0.42 percent and South Korea's benchmark Kospi (Korea Stock Exchange: .KS100) index declined 1.08 percent.

In Australia, the S&P/ASX 200 (ASX: .AXJO) fell 1.21 percent, driven by broad-based losses across its sub-indexes. The heavily-weighted financials sub-index was down 1.6 percent and the health care sub-index was lower by 1.77 percent.

Greater China markets trended lower. Hong Kong's Hang Seng Index (Hong Kong Stock Exchange: .HSI) was lower by 0.54 percent. On the mainland, the Shanghai Composite (Shanghai Stock Exchange: .SSEC) slipped 0.5 percent and the Shenzhen Composite was off by just 0.128 percent.

The greenback was mostly flat in Asia trade after firming overnight on the back of better-than-expected U.S. durable goods orders for the month of June. The measure of orders for U.S.-made capital goods last month showed the fifth consecutive monthly increase.

The dollar index (New York Board of Trade (Futures): =USD), which measures the dollar against a basket of six major currencies, stood at 93.913 at 9:39 a.m. HK/SIN, up from an overnight low of 93.152, but off Thursday's high of 94.103.

Uncertainty over the Trump administration's ability to push through proposed policies after the Republican health care bill failed repeated hurdles has weighed on the U.S. currency for the past few weeks. A slight change in the Federal Reserve's language in a statement released at the end of the Federal Market Open Committee meeting on Wednesday saw the dollar fall to its lowest point in more than a year on Wednesday.

More recently, the Republican plan to introduce a border adjustment tax was abandoned after GOP leaders acknowledged the "many unknowns associated" with the policy in a statement Thursday.

"Fading the GOP's progress seems to be the best bet," BK Asset Management Managing Director of FX Strategy Kathy Lien said in a note.

Ahead, the dollar was likely to trade with a downward bias before the release of nonfarm payrolls due next week, Lien added.

Within Asia, regional markets were likely to continue focusing their attention on corporate results, with reports due from Yahoo Japan, Nomura Holdings and TEPCO.

Hong Kong-listed insurer AIA Group (Hong Kong Stock Exchange: 1299-HK) reported operating profit after tax rose 16 percent on-year to $2.26 billion in the first half of the year, the company said in a statement issued to the Hong Kong Exchange Friday. AIA shares were down 1.32 percent.
