Summary
This Nasdaq article examines the role of ultra-low latency trading infrastructure, particularly connections operating in the 300-800 nanosecond range, analyzing contexts where extreme speed confers competitive advantage versus where it is largely irrelevant. It explores the economics and risks of high-frequency trading infrastructure in modern financial markets.
Key Points
- •Ultra-low latency connections operating in the 300-800 nanosecond range are central to high-frequency trading competition.
- •Trade speed advantages are highly context-dependent; not all market participants or asset classes benefit equally from nanosecond-level infrastructure.
- •The arms race for speed in financial markets raises questions about systemic risk and fairness in market microstructure.
- •Critical financial infrastructure increasingly depends on automated, high-speed algorithmic systems with minimal human oversight.
- •Understanding where speed matters helps regulators and firms allocate resources and assess stability risks appropriately.

As markets have become more modern, with automated trading playing a central role, the speed of trading has accelerated as technology has improved. But the speed of light hasn’t changed. It has remained constant at (roughly) 186,000 miles-per-second.
That speed is also not unique to stock-markets; it is about how fast wireless messages travel in all networks, even from our phones. That speed is also important, because the major U.S. exchanges’ data centers are located as far as 35 miles from each other. So even though it doesn’t take long to ship messages between exchanges, it’s not instantaneous. At the speed of light, messages take at least:
- 180 microseconds to cover the 35 miles from NYSE to Nasdaq data centers.
- 90 microseconds to cover the 17 miles from Cboe to Nasdaq data centers.
**Milli, Micro and Nano**
As recently as 2015, the industry referred to “fast” in milliseconds. These days most trading is done in microseconds (denoted as “µs”). You don’t need a science degree to quote latency metrics, but it helps to remember the order (in descending increments) is milli, micro and then nano.
**Table 1: How seconds compare to milli, micro and nanoseconds**
Microseconds are extremely fast. To put it into context, we can
