Oil tops $80 as US CPI looms, Taiwan stocks plunge 1,000 points

The United States Consumer Price Index (CPI), set to be released tonight, has become the focal point of global financial markets. Oil prices have continued to climb in recent weeks, with Brent crude breaking through the USD 80 per barrel threshold. This has sparked widespread market concern that rising energy costs will further drive up overall inflation. The surge in oil prices not only directly impacts fuel and transportation costs in the US but also indirectly affects various commodities such as food and industrial raw materials, creating greater uncertainty among investors regarding future inflation trends. As the release time of the CPI data approaches, investors have been adjusting their positions, and a wait-and-see sentiment has spread across the US stock market. The three major indices simultaneously moved lower, indicating that market sensitivity to inflationary pressures has reached a new high.

The US Federal Reserve will hold a crucial rate-decision meeting next week. Markets generally expect that if the CPI data shows inflation remains above the target range, the central bank may adopt more aggressive interest rate hikes or balance sheet reduction policies to curb rising prices. Conversely, if the data shows signs of moderation, there is a chance of a subtle shift in policy stance or even a pause in the pace of rate hikes. This uncertainty has led investors to adopt a cash-heavy, wait-and-see approach ahead of the CPI release to avoid excessive exposure before information becomes clear. Following previous CPI releases, market volatility has often amplified within hours, particularly as interest rate policy expectations magnify capital flows and safe-haven demand.

In Asian markets, the Taiwan Stock Exchange weighted index was also impacted by US inflation and interest rate expectations. During today's trading session, the index plummeted by nearly 1,000 points at one point, ultimately closing down 755.64 points while remaining above the 46,025-point monthly moving average. Although the decline was substantial, the index's ability to hold the monthly line demonstrates that domestic capital still possesses a certain degree of resilience under global capital outflow pressures. The performance of Taiwan stocks is closely tied to the local industrial structure; the pivotal roles of the semiconductor and electronic manufacturing industries in the global supply chain prompt foreign investors to maintain a certain holding ratio during the wait-and-see period, thereby avoiding massive sell-offs.

From a macroeconomic perspective, although Taiwan's economy is export-oriented, the simultaneous fluctuations of domestic and external demand continue to exert a dual impact on the stock market. If the US CPI data shows continued inflation, the US dollar may strengthen further, subsequently lifting the New Taiwan Dollar exchange rate and creating cost pressures for export-oriented enterprises. At the same time, global capital may flow back into the US bond market, exerting a negative impact on capital inflows into emerging markets. Conversely, if the CPI data comes in lower than expected, the market will take a more lenient view of the Federal Reserve's rate-hike pace, funds are expected to flow back into risk assets, and Taiwan stocks will have the opportunity to recover upward momentum in the future.

Overall, tonight's CPI release will serve as a crucial indicator for judging the future direction of monetary policy, and the market's wait-and-see sentiment reflects investors' sensitivity to the global economic cycle. While holding its monthly moving average despite controlled declines, the Taiwan stock market demonstrates a certain level of defensive capability. However, close attention must still be paid to US inflation trends and the latest signals from the Federal Reserve, as these will directly influence capital flows and exchange rate fluctuations, thereby dictating the competitiveness of Taiwan's export industries and the broader economic outlook.
