Emerging-market stocks fell significantly on September 14, 2026, as heightened tensions in the Middle East prompted investors to seek refuge in safer assets. This trend was exacerbated by ongoing uncertainty regarding the global interest rate outlook. The MSCI gauge of developing-nation equities saw its third consecutive session of declines, marking its longest slump in nearly two months.
A major contributing factor to the decline was a substantial drop in South Korea's Kospi index, which slid over 3%. This downturn was triggered by calls from prominent artificial intelligence firms for a slowdown in AI development. This news raised concerns about a sector that had been a key driver of the year's market rally, particularly in AI-heavy Asian shares. Notably, Samsung Electronics fell 4.1% and SK Hynix lost 6.4%, both having benefited greatly from increased AI demand earlier in 2026.
In addition to the AI concerns, rising oil prices played a significant role. Oil prices climbed approximately 3% after new strikes on Saudi Arabian energy infrastructure and Iranian attacks on ships in the Gulf, raising supply concerns. Higher oil prices are fueling inflationary worries, prompting global policymakers to reassess their monetary stances. Markets are now pricing in a near 90% chance of a U.S. interest rate hike from the Federal Reserve this week, adding further pressure to emerging markets and their currencies. The Korean won and Indonesian rupiah both weakened by 0.2% and 0.3% respectively, while MSCI's EM currency index eased 0.1% to a near two-week low.
