“Tensions between Iran and Israel will be eyed as financial markets remain hopeful that a delicate ceasefire between the two nations would hold,” analysts at UOB said in a note.
Brokerage shares led the gains, with CSI securities sub-index rallying 5.48 percent. Defence shares were also among top winners, with the sub-index jumping 3.68 percent.
Meanwhile, Premier Li Qiang said on Wednesday that he was confident the country could maintain a “relatively rapid growth rate” and transition from a manufacturing-led economy to a consumer-driven one.
US Federal Reserve chairman Jerome Powell said on Tuesday that higher tariffs could begin raising inflation this summer, a period that will be key to the US central bank considering possible interest rate cuts.
“While Powell reiterated the message that Fed need not rush to cut, he did suggest that the Fed may cut rates sooner rather than later if inflation pressures remain contained,” OCBC analysts said in a note.
“But he was careful in not committing to a timeline.”
