What Causes Supply Chain Issues?

For manufacturers, problems with the supply chain can impact everything from productivity to profitability. Exploring key factors contributing to these disruptions can help your team stay ahead of common hiccups and build stronger, more resilient logistics networks.

We are breaking down what causes supply chain disruptions and potential repercussions for businesses below. 

The Consequences of Supply Chain Disruptions

As a manufacturer, proper supply chain management is key to supporting peak operations and meeting customer demands. When disruptions occur, your business may experience the following consequences:

  • Production stoppages
  • Increasingly complex inventory management 
  • Contractual penalties
  • Higher production costs
  • Reduced capacity
  • Delayed product launches
  • Lost competitive advantage
  • Customer dissatisfaction

Supply chain issues can overwhelm operations, especially for small- and medium-sized companies. Taking action to improve your supply chain can help mitigate some of these burdens if disruptions occur. Understanding root causes can be a game-changer for businesses like yours, allowing your team to make more informed and strategic decisions.

10 Common Causes of Supply Chain Issues

Every link in the manufacturing supply chain has unique influences on its overall performance. Problems can arise from various external and internal sources. Learn more about what causes supply chain issues below.

1. Global Economic Factors

The following global economic factors can significantly impact your supply chain:

  • Excessive growth: Rapid economic growth can increase raw material and component demand, sometimes straining resources and leading to shortages.
  • Recession: Decreasing demand during economic downturns can lead to excess inventory or financial challenges for suppliers.
  • Inflation: As prices for energy, raw materials and transportation increase from inflation, disruptions may occur due to slim profit margins and limited monetary resources.
  • Trade policies: Evolving trade regulations, agreements and tariffs can majorly impact supply chains, creating barriers to trade and raising costs.

2. Severe Weather or Natural Disasters

Severe weather events, from hurricanes to prolonged droughts to tornadoes, can also wreak havoc on the manufacturing supply chain. The direct impacts could be damage to natural resources or supply facilities, causing issues like:

  • Inventory loss.
  • Equipment damage. 
  • Production interruptions. 

The effects of natural disasters and severe weather can also disrupt transportation routines, exacerbating delays. Examples include halted port operations, flooded roads, damaged bridges, closed airports and blocked railways.

Severe storms can also impact power grids, causing outages that impede everything from production to communication.

3. Labor Shortages

Manufacturing is among the top industries impacted by labor shortages. When businesses within your supply chain cannot find enough skilled employees, they may have to:

  • Reduce production capacity.
  • Delay processing, assembly and packaging.
  • Increase production costs.

Fewer skilled workers can also lead to quality control issues and defective products, further impacting production times and processes.

Understaffed teams can be inefficient. In some cases, businesses have to raise prices to accommodate higher pay for their workers as an incentive to attract and retain talent. In other cases, businesses are hiring temporary workers at higher rates, and they may pass along those expenses.

4. Regulatory Changes

Manufacturing supply chains can also experience disruptions from regulatory changes. These may include new:

  • Environmental laws on emissions, materials or waste disposal.
  • Trade regulations relating to import and export restrictions.
  • Product safety standards impacting labeling requirements or production processes.
  • Labor laws such as regulations on wages, worker safety or working conditions.
  • Data privacy laws influencing how manufacturers collect, store and trade data.
  • Transportation regulations on shipping, trucking or air freight.
Regulatory updates can result in increased costs, production delays, market restrictions and other problems.

Regulatory updates can result in increased costs, production delays, market restrictions and other problems.

5. Demand Surges or Poor Inventory Management

Inventory management can significantly impact supply chain efficiency. Unforeseen demand spikes can overwhelm and strain production capacity. Inaccurate forecasting or external events, like natural disasters, can leave manufacturers unprepared for a surge in demand for specific products. Unexpected spikes can lead to stockouts and delays.

Inadequate inventory management practices along the supply chain can also impact reliability. Poor coordination, lack of visibility and ineffective inventory control processes may lead to negative financial and productivity implications.

6. Technological or Cybersecurity Issues

Technology is a crucial element of the supply chain, and related issues, such as the following, can cause massive disruptions:

  • Critical IT system failures
  • Software glitches or bugs
  • Malfunctioning hardware or equipment
  • Data silos
  • Outdated software or machines

Similarly, cybersecurity issues can devastate manufacturing operations. From 2017 to 2023, cyberattacks on the United States supply chain increased by about 58% year-over-year, highlighting the significant threat to businesses.

Cybersecurity-related issues to consider include ransomware attacks, data breaches, phishing attacks and denial-of-service attacks.

7. Raw Material Shortages

Raw material shortages impacting the manufacturing supply chain can be the result of various events, including:

  • Natural disasters that result in destroyed crops, forests or mining operations.
  • Political conflicts or resource nationalism.
  • Surges in demand for particular products. 
  • Problems at processing plants, refiners or mines. 

Shortages can halt production, skyrocket costs and lead to other deficiencies.

8. Geopolitical Factors

Various geopolitical factors can create a ripple effect through your business’s supply chain, such as:

  • Political instability: Any instability caused by war, terrorism or unrest impacting infrastructure, transportation or security can disrupt important logistics.
  • Trade wars: Trade disputes and sanctions can restrict access to particular markets or materials, impacting sourcing and shipping processes.

Manufacturing businesses can use the Geopolitical Risk Index and Global Supply Chain Pressure Index to gauge potential issues and assess threats for proactive planning.

9. Transportation Bottlenecks

Transport-related bottlenecks can impact the supply chain by slowing — or halting — the flow of materials or goods due to congestion, capacity constraints or disrupted operations.

Various points in the supply chain can cause slowdowns, including:

  • Ports
  • Highways
  • Airports
  • Border crossings
  • Railyards

Close oversight of transportation routes is key to ensuring shipments arrive on time. 

10. Unreliable Suppliers or Partners

Working with trusted partners is crucial to supporting supply chain optimization. Unreliable suppliers can cause quality control issues, production delays and financial instability for your business.

Ensure you work with a team that prioritizes transparent communication and can handle your production capacity needs. The wrong partner can slow down efficiency and negatively affect your bottom line.
