Taiwan Strait
Taiwan Strait Shipping Data
The Taiwan Strait separates mainland China from Taiwan and serves as a vital corridor for global semiconductor supply chains, energy imports, and East Asian trade. Container ships carrying advanced chips, AI hardware, and consumer electronics share the waterway with tankers feeding Taiwan's refineries and bulk carriers supplying raw materials. FinzData's Global Macro Pulse provides daily transit counts and capacity by vessel type for the Taiwan Strait since 2019, giving traders, economists, and data scientists a point-in-time view of exactly what the market knew each day.
Why this chokepoint matters
The Taiwan Strait is the main artery for Taiwan's export-oriented economy — home to the world's leading foundry and advanced packaging capacity. Container throughput here correlates directly with the global chip cycle, AI-server demand, and consumer-electronics inventory cycles. Tanker traffic reflects energy security for an island economy dependent on imported oil and LNG. Dry bulk carries raw materials for manufacturing. Any tension, typhoon, or policy shift in the strait sends immediate signals through technology supply chains and commodity markets. Daily data by vessel type lets you separate the chip-cycle signal (containers) from energy and commodity flows.
- Container ships: track semiconductor and AI-hardware export momentum
- Tankers: monitor energy import security for Taiwan
- Dry bulk: gauge raw-material demand for manufacturing
- General cargo and ro-ro: capture regional and cross-strait trade
What the data shows
FinzData's chokepoints dataset delivers daily transit counts and total deadweight capacity for each vessel category through the Taiwan Strait since 2019. Each row is a point-in-time snapshot — what was known that day — ensuring reproducible backtests and event studies. Aggregate to weekly or monthly frequency, compute rolling averages, or compare current levels to prior-year baselines. The five vessel-type breakdown enables granular analysis of how different segments respond to the chip cycle, geopolitical events, seasonal patterns, or policy changes.
- Daily frequency, 2019 to present
- Five vessel-type breakdowns
- Transit counts and capacity (deadweight tonnes)
- Point-in-time snapshots for reproducible research
How to use it
Access the data through your FinzData API key with a simple GET request: GET https://api.finzdata.com/v1/pulse/chokepoints?match=taiwan-strait. The MCP tool get_global_pulse also surfaces this series for AI-assisted workflows — ask Claude, ChatGPT, or Grok with the FinzData connector. Combine with Asia tech exports (Taiwan and Korea chip and AI-hardware series with every vintage) for a complete semiconductor supply-chain view. The same key unlocks 16,000+ US stocks, 5,100+ ETFs, 139 futures markets, and 18,000+ macro series for cross-asset modeling.

Frequently asked questions
What vessel types are covered?
Container ships, dry bulk carriers, tankers, general cargo vessels, and roll-on/roll-off ships — each with daily transit counts and capacity.
How far back does the data go?
Daily data starts in 2019 and continues to the present.
Is the data point-in-time?
Yes. Each row reflects what was known on that date, with no look-ahead bias, so backtests and event studies are reliable.
Can I combine this with Asia tech exports?
Yes. The same API key provides Taiwan and Korea chip and AI-hardware export series with every vintage (first release and revisions), plus 16,000+ US stocks, 5,100+ ETFs, 139 futures markets, and 18,000+ macro series.
