Asian shares mostly dip after US stocks rally

Asian shares mostly declined despite a U.S. stock rally driven by easing oil prices, as investors assessed the impact of a joint U.S.-Japan currency intervention. Key indices like Japan's Nikkei 225 and Hong Kong's Hang Seng fell, while Australia's S&P/ASX 200 rose. Analysts debated the intervention's long-term effectiveness amid persistent economic factors like inflation and interest rates.
