Asia-Pacific markets fell on Wednesday as investors weighed elevated bond yields and renewed geopolitical tensions, following U.S. President Donald Trump's statement on Tuesday that he was "an hour away" from deciding to attack Iran, before he was persuaded to postpone the strike for a few days.

Yields on U.S. Treasurys advanced as investors continued to dump bonds on fears inflation is reigniting. The longer-dated 30-year Treasury bond yield was last trading almost 1 basis point lower at 5.174%. It briefly hit 5.197% during the session, marking its highest level since July 2007.

Japan's Nikkei 225 lost 0.88%, while the Topix declined 0.75%. South Korea's Kospi fell 0.52%, while the small-cap Kosdaq dropped 2.15%.

In Australia, the S&P/ASX 200 lost 0.5%.

Hong Kong's Hang Seng index futures were at 25,603, lower than the index's last close of 25,797.85.

U.S. stock futures ticked slightly higher. S&P 500 futures added 0.14%, while Nasdaq 100 futures added 0.25%. Futures tied to the Dow Jones Industrial Average rose 55 points, or 0.11%.

Overnight on Wall Street, stocks closed lower with the S&P 500 posting its third straight losing session, as a jump in bond yields threatened the bull market.

The S&P 500 closed down 0.67%, ending at 7,353.61, while the Nasdaq Composite finished 0.84% lower at 25,870.71. The Dow Jones Industrial Average shed 322.24 points, or 0.65%, to close at 49,363.88.
