Asian indexes closed mixed on Tuesday as markets awaited MSCI's decision on the potential inclusion of mainland Chinese stocks, even as the dollar strengthened.

Investors are keeping an eye on the decision on whether to include China A-shares in the MSCI Emerging Markets Index. This will be China's fourth attempt at MSCI inclusion , after being passed over the first three times.
While MSCI inclusion is not "of vital importance" to China, it will be beneficial in terms of capital flows, said Clive McDonnell, head of equity strategy at Standard Chartered Private Bank.
"If A-shares are admitted to (the MSCI) EM (Index), it could over the longer term have a positive effect on capital inflows to China, which would help support the currency over the medium term," McDonnell said.
Whether China's latest attempt will succeed remains to be seen.
"I still think it's about fifty-fifty as to what will happen," Janus Henderson Investors Portfolio Manager Sat Duhra told CNBC. While China was in the "best position they've been for a number of years" for MSCI inclusion, obstacles — such as the high proportion of suspended stocks — remained, Duhra added.
Overnight, the dollar strengthened and U.S. Treasury yields rose on comments from New York Fed President William Dudley expecting that inflation should rise faster going forward, allowing the Fed to proceed with tightening monetary policy.

Meanwhile, the ratings downgrade of Australia's banks, including the big four, by Moody's Investor Services overnight is not expected to affect their funding costs , Reuters quoted Deutsche Bank analysts as saying.

Shares of the big four Australian banks closed in negative territory. ANZ was down by 1.34 percent, National Australia Bank fell 1.09 percent and Commonwealth Bank of Australia shed 0.66 percent.
The Australian dollar , which initially sold off on the news, traded at $0.7610 at 3:00 p.m. HK/SIN compared to levels around $0.7596 seen in the previous session.
"Our outlook for the Australian dollar is relatively constructive. We still expect the Australian dollar to head towards $0.77 by year-end, early next year as well. The big support for the Australian dollar is the fact that commodity prices, at least iron ore prices, appear to be bottoming out, or at least forming a base," Commonwealth Bank of Australia Senior Currency Strategist Elias Haddad told CNBC.
As well, the Reserve Bank of Australia released the minutes of its June review that reflected that the central bank was concerned about household debt and wage growth, even though it was positive about growth going forward. The RBA had held cash rates steady earlier this month due to weak growth.
