IMF PortWatch — Daily Chokepoint Vessel TransitsIMF PortWatch — 关键海上航道每日船舶通行量

IMF PortWatch uses satellite AIS vessel-tracking data to monitor activity and disruptions at the world's major maritime chokepoints in near real time. This page reports the daily NUMBER OF VESSELS transiting each of 28 strategic chokepoints — including the Suez and Panama Canals, the Strait of Hormuz, Bab el-Mandeb, the Malacca and Taiwan Straits, and the Cape of Good Hope detour route — from 2019 to the present. The figures are vessel transit counts, not trade value, tonnage, or capacity.

Sharp moves track real shipping shocks: transits through the Suez Canal and Bab el-Mandeb roughly halved through 2024 as Red Sea attacks pushed shipping onto the longer Cape of Good Hope route, making this a useful indicator of supply-chain and chokepoint-disruption risk. This version uses PortWatch's daily chokepoint transit file; the monthly port/chokepoint and disruption files are not included on this page.

IMF PortWatch 利用卫星 AIS 船舶定位数据，近实时监测全球主要海上咽喉的通行活动与中断情况。本页给出 2019 年至今、28 个战略性航道每日通行的船舶数量——包括苏伊士运河、巴拿马运河、霍尔木兹海峡、曼德海峡、马六甲海峡、台湾海峡，以及绕行非洲的好望角航线。此处数值为每日船舶通行艘数，并非贸易额、货运吨位或运力。

数值的剧烈变动对应真实的航运冲击：2024 年红海袭击事件使苏伊士运河与曼德海峡的通行量几近腰斩，大量船舶改走更长的好望角航线，因此本数据可用于衡量供应链与关键通道中断风险。本版仅使用 PortWatch 的日度航道通行文件，月度港口/航道与中断（disruptions）文件未纳入本页。
