1. What is the Strait of Hormuz and why is it so important?
The Strait of Hormuz is the narrow waterway between the Persian Gulf and the Gulf of Oman. Approximately 20% of global oil transport and large quantities of liquefied natural gas (LNG) as well as petrochemical products normally pass through here. Since the end of February 2026, the route has been de facto blocked by Iranian military actions. This is leading to sharply rising energy prices and delays in global supply chains.
2. Does the closure directly affect medical supply?
Not immediately on a large scale, but indirectly and potentially noticeably. Only a very small fraction of medicines and active ingredients are produced directly in the Middle East. The main problems arise from:
- Sharply rising energy and transport costs
- Delays in raw materials and intermediate products
- Potential shortages of basic chemical substances
In the short term (up to a few weeks), inventories can usually still secure supply. However, a longer blockade (over 4 weeks) threatens noticeable impacts.
3. What are the specific impacts on medicines?
- Higher production costs: Many medicines, especially generics, are based on petrochemical derivatives (e.g., basic chemicals derived from oil and gas such as ethylene, propylene, or methanol). Rising oil and gas prices increase manufacturing costs worldwide.
- Indirect effects via Asia: Europe sources a large portion of its active ingredients from China and India. India imports a significant amount of its crude oil via the Gulf region and uses logistics hubs in the United Arab Emirates. Disruptions there can affect the production of generics (e.g., antibiotics, painkillers, anti-inflammatories).
- Logistics problems: Rerouting around the Cape of Good Hope extends transport times by 10–14 days and massively increases costs. Air freight for temperature-sensitive medications is also affected by limited capacity in the Gulf region.
- Potential shortages: If the duration is longer, supply-critical active ingredients could become scarcer, especially if Asian production is burdened by higher energy costs.
4. What role do special chemicals and gases play?
The chemical industry warns of shortages of substances that are also relevant to medicine:
- Helium: A large portion of global helium comes from Qatar. Helium is needed for cooling MRI scanners and in medical diagnostics. Shortages could make diagnostics more expensive or delay them.
- Ammonia, sulfuric acid, and other petrochemical precursors: These are used in the production of packaging, plastics (e.g., for syringes, catheters, gloves), or in the synthesis of active ingredients.
5. Do the effects also affect medical devices (MedTech)?
Yes. Disposable products such as syringes, nitrile gloves, catheters, or packaging materials are often based on plastics derived from petrochemical raw materials. Manufacturers are already reporting cost increases for plastics and packaging. Energy costs for production are also rising. Cold chain transport for vaccines or biologics is particularly vulnerable to delays.
6. How severely are Germany and Europe affected?
Germany and Europe do not have direct major oil imports via Hormuz but are indirectly heavily dependent through global supply chains and energy prices. The German Association of the Pharmaceutical Industry (BPI) and the Association of the Chemical Industry (VCI) warn of increasing risks. Federal Minister of Health Nina Warken has pointed to possible consequences for the drug supply. If a blockade lasts more than four weeks, delays in complex supply chains could escalate.
7. When might patients notice something?
- Short-term (up to approx. 4 weeks): Mostly just higher prices (e.g., for over-the-counter medications) or slight delays for specialized medications. Pharmacies and hospitals usually have buffer stocks.
- Medium-term (longer than 4–8 weeks): Possible shortages of certain generics, rising prices for medications and medical devices, and higher costs in the healthcare system.
Chronically ill patients who rely on affordable generics, as well as areas such as diagnostics (MRI) or intensive care medicine, would be particularly affected.
8. What are the authorities and the industry doing?
The federal government is in contact with the pharmaceutical industry, wholesalers, and pharmacies. Companies are trying to reroute supply chains, increase inventory levels, and find alternative suppliers. Experts are calling for greater diversification of active ingredient production in the long term to reduce dependence on Asia.
9. How long could the blockade last and what would be the consequence?
This depends on the course of the conflict. Short disruptions (up to 2 weeks) have limited effects. From four weeks and longer, problems in the complex supply chains escalate – with rising prices, possible shortages, and burdens on the healthcare system.
Summary
The Strait of Hormuz blockade affects medicine primarily indirectly through higher energy and logistics costs, as well as disrupted global supply chains for active ingredients and chemical precursors. A short crisis can largely be cushioned. However, a longer blockade threatens noticeable price increases and possible supply shortages – especially for generics and certain medical devices. The situation is being closely monitored by associations and politicians.
Patients should inform themselves at their pharmacy or doctor if necessary. For current developments, official sources such as the Federal Ministry of Health or the Pharmaceutical Journal are recommended.
