In the context of infrastructure, systemic risk is a cumulative risk to a system as an outcome of physical, biological, social, environmental, or technological shocks and stresses. These may be internal or external to the system. Impact on individual components of the system (assets, networks, and subsystems) becomes systemic due to interdependence and interactions between them.
1. Systemic risk can be seen as a feature of systems at all possible scales – global, national, regional, and local – with varying system boundaries depending on the context.
2. Interactions within a system can either aggravate or contain the overall effect of the constituent parts, creating the potential for cascading impacts on system elements far from the first impact. See also "Feedback loops".
3. A key attribute of systemic risk is that it can transgress spatial and sectoral boundaries in relation to other systems, sectors, and geographical regions, thus leading to cascading effects. See also “Cascading hazards”.
4. Systemic risk management requires a holistic understanding of the interconnected, complex, and non-linear cause-effect relationships between the system’s elements to identify appropriate responses. See also “Organizational learning” and “Infrastructure linkages”.

Disasters in the readymade garment industry, Dhaka, 2013
An eight-storey commercial building, Rana Plaza on the outskirts of Dhaka collapsed on 24 April 2013. Around 1,100 people lost their lives and many more were left with life-long injuries. The building owners had refused to shut down the building inspite of being warned about cracks appearing in the building the day before. Garment workers had been ordered to return to work on the following day, and the building subsequently collapsed during the morning rush hour. The collapse was due to:
- The building was built on a filled-in pond, compromising structural integrity.
- The building had been converted from commercial use to industrial use, and heavy industrial machinery was installed which caused vibrations.
- Four floors had been added above the original permit.
- Substandard construction materials had been used.
