On Tuesday, US government data showed the annual increase in CPI had slowed slightly in August to 8.3 percent, but that prices continued to rise month-on-month, increasing by 0.1 percent.
The news shook equity markets, where there had been widespread expectations of US year-on-year inflation being around eight percent, with a decrease in prices compared with July.
Tokyo led the day's losses in Asia, with the Nikkei 225 plunging 2.8 percent.
In Hong Kong, stocks closed down more than two percent, with Chinese conglomerate Fosun seeing billions wiped off its value as jittery investors reacted to media reports that the group was under regulator scrutiny.

Wall Street shares plunged following the CPI news, with the Dow losing nearly 1,300 points and the S&P 500 falling 4.3 percent on Tuesday.
The data will have dashed hopes of a slowdown in the US Federal Reserve's campaign of increasing interest rates to cool the overheating economy.
The Fed has already instituted two consecutive 75-basis-point hikes, and there are widespread expectations it will make a similarly sized increase at its meeting next week.
After Tuesday's data, however, some investors are now predicting the next Fed hike could be by a full percentage point.
Of concern to the Fed will be the fact that "core" US CPI, which excludes volatile food and energy prices, accelerated sharply, rising 6.3 percent on a year ago, higher than the 5.9 percent seen in July and June.
Despite welcome relief from falling gasoline prices, food, housing and medical care costs continued to rise.
"Core inflation was scorching hot, coming in double expectations," said senior market analyst Edward Moya at OANDA.
"The Fed will likely have to be even more aggressive with raising rates and that is bad news for risky assets."
Investor Louis Navellier warned that persistently high interest rates to control inflation could lead to a US recession.
"Stocks are taking it very hard as forecasts are rising for Fed Funds to get higher and stay there longer resulting in a discount of future earnings multiples and increasing recession fears," he said in a note.
In Britain, new data Wednesday showed inflation eased in August, but it remains close to the previous month's 40-year peak as the country battles a cost-of-living crisis.

The yen plunged to 144.94 against the US currency, before recovering sharply following reports that the Japanese central bank had conducted a "rate check", an exercise often seen as a precursor to currency intervention.
