CPI inflation unexpectedly rose to 2.1% YoY in March (vs 1.9% market consensus)

South Korea recorded an unexpected rise in inflation in March thanks to higher processed food (3.6%) and eating-out prices (3.0%). Both accelerated more than expected as companies passed on increased input price to consumers. One-off price increases for university tuition (5.2%) and kindergarten fees (4.2%) also contributed to price gains in March. Yet fresh food prices continued to fall for a second month, down 1.3% in March. Fuel prices also eased to 3.0% (vs 6.8% in February) amid falling global oil prices.

Today’s reading showed that easing supply-side trends are putting downward pressure on prices. But higher import costs are pushing prices up. This will complicate the Bank of Korea’s policy decision ahead.

BoK watch

The BoK may now pay more attention to core inflation remaining below 2%. At the same time, though, the weakness of the USDKRW bears watching in the coming months. The Constitutional Court ruling on President Yoon’s impeachment will be announced on 4 April. As such, the won is open to risk in both directions in the very near term, depending on the outcome of the ruling.

Just like markets, we expect the BoK to keep its policy rate at 2.75% at its April meeting. Policymakers need to analyse the impact of the previous rate cuts and assess how US tariff policies will affect the economy. Also, the BoK will be wary of the current weakness in the USDKRW. It's driven by global risk-off sentiment and domestic political uncertainty, a dynamic that has persisted in recent months. The BoK will watch to see if this pushes up prices further.

Going forward, processed food prices are expected to rise further, while and fresh food prices may rebound again due to recent adverse weather conditions. Meantime, the government efforts to curb prices will continue. This morning, the government announced that it would freeze utility fees (power and gas) in the first half of 2025 and increase spending to stablize fresh food prices.

We currently expect a rate cut in May. But depending on the inflation path and currency moves, the BoK may delay its rate action until the third quarter of 2025.

This is an interesting development for South Korea’s monetary policy. With inflation picking up, the Bank of Korea may have to delay rate cuts, which could impact market sentiment and economic growth projections. It’ll be worth watching how policymakers balance inflation control with economic support in the coming months.
