Asian shares mixed as oil prices climb; Japan flat, Seoul down, Hong Kong up

Asian shares traded mixed Monday as oil prices rose, with Japan's Nikkei nearly flat, South Korea's Kospi falling 2.3%, and Hong Kong's Hang Seng gaining 0.7%. U.S. crude climbed 1% to $93.33 a barrel. Last week, cooling oil prices helped U.S. stocks post their first winning week in three, with the S&P 500 rising 0.5%. Oil remains volatile due to uncertainty over the Iran war's impact on Middle East shipping, including the Strait of Hormuz. Rising U.S. inflation expectations had weighed on markets, pushing the 10-year Treasury yield near 5.22%, its highest since 2007, before easing to 5.15%. High yields slow economic growth and undercut stock prices.
