Energy costs increase inflationary pressure! South Korea's Producer Price Index (PPI) in May rose by 8.5% year-on-year, reaching a near four-year high.

Producer price inflation in South Korea continues to rise, making the market's judgment on the direction of the South Korean central bank's monetary policy increasingly complicated. According to data released by the South Korean central bank on Friday, the PPI in May increased by 8.5% year-on-year, the largest annual increase since July 2022, with the previous month's data also being revised upwards. On a month-on-month basis, prices rose by 0.8% compared to April, marking the ninth consecutive month of month-on-month growth. The central bank of South Korea pointed out that this round of price increases was mainly driven by petroleum and coal products, chemical products, and technology-related manufacturing, with chemical products and computer and electronic product prices rising by about 20% compared to the same period last year, the latter reflecting the sustained strength of the semiconductor-related industry. The above data further strengthen the market's concerns about the persistent high inflation pressure in South Korea. At the same time, the South Korean central bank maintained the benchmark interest rate at 2.5% in May but signaled a bias towards tightening. The minutes of the meeting, published earlier this week, showed broader support within the committee for this hawkish stance. Energy shocks are the driving force According to Bloomberg, the Iran war has pushed up energy prices, which is an important backdrop for the current acceleration in producer prices. Although the temporary peace agreement between the US and Iran has taken effect, oil prices remain relatively high, and it is expected to take several months or even longer for the flow of goods through the key shipping route of the Strait of Hormuz to return to normal. This means that the transmission effect of energy costs on upstream production prices is unlikely to diminish in the short term, and the continued upward trend in oil and coal product prices will continue to permeate downstream industrial chains. Semiconductors driving technology manufacturing prices higher In the field of technology manufacturing, computer and electronic product prices have increased by about 20% year-on-year, which the South Korean central bank attributes to the continued prosperity of the semiconductor-related industry. This sub-item data indicates that the price pressure in the technology manufacturing industry is not only driven by cost factors but also by demand-side factors, providing additional support for the overall producer price index. Central bank's hawkish signal becoming clearer Faced with the coexistence of inflationary pressures and financial stability risks, the policy stance of the South Korean central bank is gradually leaning towards hawkishness. Although the interest rate meeting in May remained unchanged, the central bank clearly signaled a bias towards tightening. The minutes of the meeting published this week further showed an expanded support within the committee for this stance. The continuous rise in producer prices typically transmits to consumer prices a few months later, and if this trend continues, it will provide more solid grounds for the South Korean central bank to raise interest rates in the future. Investors need to closely monitor subsequent inflation data and central bank statements.
