Kenya’s $2.3 Billion Export Crisis: How the Strait of Hormuz Blockade Crushed Flowers and Tea

The Iran-US conflict that effectively closed the Strait of Hormuz on February 28, 2026, has wiped $4.8 million from Kenya’s flower exporters in three weeks and stranded 8 million kilograms of tea in Mombasa warehouses, revealing how geopolitical shocks cascade through emerging-market commodity chains via logistics bottlenecks that no amount of domestic policy can control.

War-risk Insurance premiums have surged from 0.25 percent to as high as 10 percent of vessel value, per the Food and Agriculture Organization, with coverage resetting every seven days as underwriters struggle to price escalating risk. Tanker traffic through the strait collapsed by more than 90 percent within days of the February escalation — from 3,000 vessels per month to roughly 150 — leaving Kenya’s export-dependent floriculture and tea sectors exposed to what the World Food Program has called “the largest disruption to humanitarian supply chains since the Covid pandemic.”

Margin Compression and Workforce Cuts

Kenya’s flower industry, valued at $835 million in 2024, is losing up to $1.4 million per week, according to the Associated Press in late March. Farms heavily dependent on Middle Eastern markets — which account for 10-15 percent of Kenya’s flower exports — have seen revenue declines of up to 75 percent. Freight charges climbed 9 percent to Sh545.6 per kilo from Sh493.6 before the conflict, reaching $5.80 per kilo by late March, the highest level in a decade, per Kenya Flower Council CEO Clement Tulezi.

“We are seeing a reduction in movement, delays in movement of produce, and longer routes, while pricing is extremely high,” Tulezi told reporters on March 24. “Last week, we were at $5.80 per kilo, which is the highest we’ve had in the last 10 years.”

The tea sector faces parallel devastation. Kenya exported approximately 13 million kilograms of tea to Iran in 2024, valued at Ksh4.26 billion, with Middle East markets accounting for 20-25 percent of total tea exports. Since March 1, the sector has been losing approximately $8 million per week, per AgriFocus Africa in early April. By mid-April, the Kenya Tea Development Agency Holdings reported tea worth Ksh3 billion ($23.3 million) sitting in warehouses due to lack of Shipping capacity.

The Logistics Chokepoint Transmission Mechanism

The crisis exposes three distinct transmission channels through which distant geopolitical shocks crush emerging-market exporters. First, war-risk insurance premiums create immediate margin compression. For very large oil tankers, the increase from 0.125 percent to between 0.2 and 0.4 percent of ship insurance value represents a quarter-million-dollar increase per transit, costs that cascade downstream to all cargo.

“If the situation changes by the hour, the risk becomes almost impossible to price responsibly,” Oscar Seikaly, CEO of NSI Insurance Group, told Al Jazeera in late April. Underwriters are resetting coverage every seven days rather than offering annual contracts, creating pricing volatility that makes export planning impossible.

Second, transit time extensions destroy value for perishable goods. Air cargo delays of up to 48 hours and maritime delays of 10 to 20 days, as reported by Kenya’s Trade Cabinet Secretary Lee Kinyanjui on April 21, mean flowers wilt and tea degrades before reaching buyers. European freight rates have risen by more than 20 percent in some cases, the Kenya Flower Council noted.

Third, currency and input-cost transmission amplifies the shock. The Kenyan shilling, trading at 129.15 per dollar on April 30, has been flagged by Wall Street banks as Africa’s most vulnerable currency, with forecasts calling for a move toward 134 by year-end, per Bloomberg. Diesel prices climbed by Ksh40.30 per litre as of April 15, driving up tea processing and transport costs. Fertilizer prices surged in March — Middle East granular urea up 19 percent in the first week alone, Egyptian urea up 28 percent — further squeezing farm-level margins.

Workforce Fallout and Sector Restructuring

The margin compression is forcing rapid workforce adjustments. While comprehensive April-May layoff data is not yet available, the trajectory is clear from earlier industry stress. Oserian Development Company, one of Kenya’s largest flower farms, laid off 800 employees in September 2025 and placed the remaining 400 workers on 50 percent pay cuts, per the Daily Nation. Industry sources indicate similar cuts are now accelerating across farms with Middle East exposure, with some operations reducing workforces by 30-40 percent since the February escalation.

The Kenya Association of Manufacturers reported in late April that the sector is under significant strain, with increased shipping costs, delayed inputs, and raw material shortages raising the cost of doing business across manufacturing supply chains. Approximately Sh164.6 billion ($1.28 billion) in annual exports to the Middle East is at risk due to the Strait of Hormuz disruptions, according to Trade Cabinet Secretary Kinyanjui.

Policy Response and Structural Limits

The Kenyan government announced on April 21 that it had secured alternative cargo routes to reduce reliance on single transit corridors, though specific routing details and cost differentials were not disclosed. “The current situation underscores the need to reduce reliance on single transit corridors,” Kinyanjui said, acknowledging the structural vulnerability.

But alternative routes cannot solve the insurance and demand-destruction problems. Even if Kenyan exporters reroute shipments around the Cape of Good Hope — adding 10-14 days to Europe-bound cargo — war-risk premiums remain elevated across all Middle East-adjacent waters, and perishable goods cannot absorb the additional transit time without quality degradation. Air freight, while faster, is now prohibitively expensive for all but the highest-margin products.

The brief ceasefire from April 8-17 offered limited relief, but tensions reignited before shipping volumes could recover meaningfully. As of early May, roughly 2,000 vessels remain stranded or rerouted, and insurers show no sign of reverting to pre-crisis premium structures until mine-clearance operations are complete and political risk subsides — a timeline that industry analysts estimate at months, not weeks.

What to Watch

Monitor three indicators for signals of sector stabilisation or further deterioration. First, watch whether war-risk insurance premiums begin to decline below 5 percent of vessel value and shift to monthly rather than weekly reset cycles — a sign that underwriters see diminishing tail risk. Second, track whether the backlog of stranded tea in Mombasa warehouses begins to clear by mid-May; prolonged storage will degrade product quality and force price markdowns. Third, observe whether the Kenyan shilling stabilises above 130 per dollar or continues weakening toward 134 — further depreciation will compound input-cost inflation and squeeze margins even if freight costs moderate. The FAO’s chief economist warned in late March that 30-35 percent of crude oil, 20 percent of natural gas, and 20-30 percent of fertilizers are not moving out of the Gulf region, meaning Kenya’s input-cost pressures will persist regardless of export-route adjustments. Any farm announcing workforce reductions beyond 40 percent signals that the crisis has shifted from cyclical disruption to structural contraction.
