Iran war triggers supply shock, factory costs surge and bonds 5month turbulence

Geopolitical shocks caused by the Iran war are disrupting supply chains and putting factories under cost pressure. Delays in sourcing raw materials and procuring parts are disrupting some manufacturers’ operating plans. Changes to shipping routes and additional quarantine and inspections are extending shipping times.

Maritime shipping costs and marine insurance premiums are rising. As ships take longer routes, fuel consumption is increasing. As a result, logistics costs are rising immediately.

Industries that use large quantities of basic materials and intermediate goods, including chemicals, metals, auto parts and electronic components, are being affected immediately. Some factories are slowing production or adjusting production lines because of parts shortages. Companies are considering ways to reflect higher costs in their selling prices.

Global bond markets 5saw significant volatility during the month. Alongside funds moving into some government bonds amid safe-haven demand, there were periods of sharp rises and falls in yields. Bond volatility also affected companies’ short-term financing costs.

Factories are responding by increasing inventories and diversifying their sourcing. Some companies are listing higher insurance premiums and transportation costs as separate expense items. In the short term, cost pressures are likely to weigh on earnings.

Market participants are monitoring supply-related disclosures, further announcements from shipping and insurance companies, and bond market indicators. Companies’ quarterly earnings and cash flow reports are key indicators for assessing the impact of rising costs. Whether supply shocks persist will determine cost structures and financing conditions.
