Asia currencies, stocks down as Middle East jitters, bond sell-off weigh

• Japanese government bond yields hit new decade highs amid US rate worries
• Indonesian ex-governor registers for presidential race as election season begins   
• China's new home prices extend declines, defying broader recovery

Indonesia's rupiah led declines in emerging Asian currencies on Thursday, while Malaysia's ringgit fell to a 25-year low, as rising expectations that U.S. Federal Reserve will keep rates higher for longer pushed U.S. Treasury yields to a 16-year high.

Equities in the region also lost ground as investors remained cautious on worries of growing geopolitical tension in the Middle East.   

The rupiah <IDR=> fell as much as 0.8% to its lowest since April 2020, ahead of a Bank Indonesia policy decision. It is expected to leave its interest rate unchanged. 

"Rupiah's underperformance will remain the policy focus, driven by narrowing policy differentials (ID vs US), weak debt portfolio flows and a firm U.S. dollar," analysts at DBS wrote.

Malaysia's ringgit <MYR=> weakened as much as 0.4% to its lowest level since 1998. The Philippine peso <PHP=> and the Thai baht <THB=TH> fell 0.2% and 0.1%, respectively.    

The South Korean won <KRW=KFTC> weakened 0.6% as risk-off sentiment dominated markets, even as the Bank of Korea kept its interest rate unchanged for a sixth straight meeting.

"The immediate impact is the continuing rise in the U.S. bond yields that has helped to push the dollar stronger and as a result negatively impacted Asian market today," said Khoon Goh, head of Asia research at ANZ.

However, a Reuters poll found that the Federal Reserve will keep its key interest rate on hold on Nov. 1 and may wait longer than previously thought before cutting it.

All eyes turn to Fed Chair Jerome Powell, who is taking part in a discussion on the economic outlook at the Economic Club of New York at 1600 GMT.

The poor market sentiment can also be attributed to uncertainty regarding the Israel-Hamas conflict, according to ANZ's Goh.

The negative sentiment spilled over into Asian equities with stocks in Shanghai <.SSEC>, Seoul <.KS11> and Singapore <.STI> falling between 1.1% and 1.8%.
