Asian markets tumble as oil surge stokes inflation concerns

Asian stock markets extended declines on Thursday as surging oil prices fanned fresh concerns about persistent inflation, prompting investors to reassess their positions across equities and fixed-income securities.

Japan's Nikkei 225 index fell 2.8 per cent, while South Korea's KOSPI shed 2.7 per cent as traders reacted to escalating energy costs. The declines reflected broader anxiety rippling through regional bourses, where investors grappled with the implications of elevated crude prices for monetary policy and corporate earnings across energy-intensive sectors.

The selloff extended to global bond markets, where yields climbed as investors repriced their inflation expectations and anticipated longer-lasting pressure on consumer prices. The shift marked a departure from recent trading patterns and underscored the sensitivity of markets to energy price movements in an environment where central banks remain vigilant about price stability.

Analysts noted that the combination of rising oil prices and cooling growth signals had created a challenging backdrop for asset valuations. The market reaction highlighted investor concerns that elevated energy costs could complicate the path toward inflation targets, potentially constraining the scope for interest-rate cuts that some market participants had anticipated in coming months.
