U.S. inflation has risen again. The Bureau of Economic Analysis (BEA) reported that the Personal Consumption Expenditures (PCE) price index increased by 3.8% in April compared to the same month last year, marking the highest rate of increase since May 2023. Excluding energy and food, the core PCE also rose by 3.3%, indicating persistent inflationary pressures. The PCE is a key price indicator that the Federal Reserve considers when making monetary policy decisions.
Market attention is focused more on the trend than the numbers themselves. Until last year, there were growing expectations that inflation would gradually ease and the Fed would begin cutting interest rates. However, the April data suggests that those expectations may have been premature. The conflict between the U.S. and Iran, rising energy prices from the Middle East, tariff burdens, and the costs of supply chain restructuring have pushed the U.S. economy back into a prolonged period of high inflation and high interest rates.
The immediate cause of the price increase is energy prices. Concerns over the Iran conflict and the blockade of the Strait of Hormuz have driven up oil prices, with April energy price increases leading the PCE rise. Reports indicate that gasoline and other energy product prices rose by 5.5% compared to the previous month. Energy is not just a simple consumer item; it acts as the economic blood pressure, pushing up logistics costs, manufacturing expenses, and service prices.
However, the issue cannot be solely attributed to the war. The U.S. economy was already facing structural inflationary pressures. Tariff policies have increased import price burdens, while the AI investment boom is simultaneously stimulating demand for electricity, data centers, semiconductors, and construction. The shift from a China-centric supply chain to reshoring and friend-shoring is also raising costs. The era of low-price globalization is ending, giving way to a more expensive security-oriented economic order.
Wall Street's anxiety stems from this situation. The market once viewed a Fed interest rate cut as a foregone conclusion. However, as inflation has risen back into the high 3% range, expectations for rate cuts have significantly diminished. Some economists are suggesting that the Fed may maintain the current benchmark interest rate of 3.50% to 3.75% for an extended period.
U.S. interest rates set the benchmark for the global economy. If U.S. rates remain high, the dollar strengthens, putting pressure on emerging market currencies and capital markets. South Korea is no exception. A delay in U.S. rate cuts will limit the Bank of Korea's monetary policy options. A high exchange rate will push up import prices, directly impacting the cost of living in South Korea, which heavily relies on energy and raw materials.
Particularly, South Korea faces significant household and self-employed debt burdens. Prolonged high interest rates will reduce consumer spending capacity and increase financial pressures on the real estate market and small businesses. While a weaker won may benefit some exporters, the overall population will face rising import prices and living costs. The resurgence of global inflation will inevitably burden the South Korean economy.
History shows the high cost of underestimating inflation. After the oil shocks of the 1970s, the U.S. experienced stagflation, where inflation and recession occurred simultaneously. While it cannot be definitively stated that the current situation mirrors that era, it is clear that energy shocks and geopolitical risks can stimulate inflation expectations, warranting vigilance.
South Korea has clear steps to take. First, it should not rely solely on expectations of interest rate cuts. Second, it must review its energy import structure and stockpiling systems. Third, it needs to provide targeted support to vulnerable groups to alleviate price burdens without compromising fiscal health. Fourth, enhancing productivity in AI, semiconductors, and manufacturing is essential to build resilience against a high-cost economy.
The 3.8% rise in the U.S. PCE is not just a foreign price indicator; it serves as a warning that the global economy is once again facing the shadow of inflation. What is needed now is neither hasty optimism nor excessive fear, but rather calm judgment and proactive preparation. This is the fundamental and sensible approach to navigating the newly reignited era of global inflation.
