Active and seasonal supply-side risks affecting citrus (oranges, mandarins, lemons, limes, grapefruit) markets.
Pathogen Candidatus Liberibacter bacteria transmitted by Asian citrus psyllid. No cure exists; tree removal only option. Symptoms: yellow shoots, blotchy leaves, small misshapen fruit, bitter juice, tree death. Florida production collapsed 92% from 1997-98 peak (240M boxes → 18M boxes). Spreading in Brazil, Texas, California, China. Single largest existential threat to global citrus.
Florida orange belt directly exposed to Atlantic hurricane season Sep-Nov. Hurricane Ian (Sep 2022) and Idalia (Aug 2023) caused 30-70% crop losses. Compounds HLB damage. Drives FCOJ price spikes ($3-4/lb 2023-24). Climate change increasing hurricane intensity.
Citrus trees damaged at -2°C; killed at -6°C. Texas 2021 Uri freeze devastated grapefruit. Florida occasional freezes destroy crop. Brazil frost rare but catastrophic when occurs (1994 Black Frost). Mediterranean periodic frost events.
Fungal disease (Phyllosticta citricarpa) causing cosmetic fruit lesions. EU bans imports from CBS-positive regions. Significant trade barrier for South Africa, Argentina exports to EU. Periodic detections trigger interceptions and regional bans.
Spain (Valencia, Murcia) chronic water scarcity worsening. South Africa Western Cape periodic drought (2017-18 Day Zero, 2024-25 dry). Citrus is irrigation-dependent (1,000-1,500mm annual requirement). Long-term production capacity risk.
USA OJ consumption peaked ~5 gallons/capita 1990s; now ~2 gallons/capita - 60% decline. Causes: competition from sports drinks, energy drinks, coffee, smoothies; sugar concerns; price increases. Europe similar trend. Structural demand erosion for FCOJ - Brazilian processors most exposed. NFC growing as substitute.
Bacterial disease (Xanthomonas citri) causing lesions on fruit/leaves/stems. Quarantine + eradication programs. Florida abandoned eradication 2006 - now endemic. Texas, Argentina also affected. Limits some export markets.
Strict phytosanitary rules driven by HLB risk severely limit fresh citrus imports to USA. Most fresh citrus markets closed. Mexican limes + South African oranges have specific protocols. Drives USA dependence on domestic production despite Florida collapse.
South African export logistics severely strained: Durban, Cape Town port congestion. Eskom load-shedding affects packing house cooling. Recurring rail/transport disruptions impact citrus export season Apr-Oct.
Brazilian Real, South African Rand, Euro swings affect competitiveness. Weak BRL = competitive Brazil FCOJ. Weak ZAR boosts South African fresh exports. EUR strength affects Spanish competitiveness vs SH suppliers.
EU-South Africa FTA + EU-Morocco + EU-Egypt agreements provide duty-free citrus access. Erodes Spanish competitive position in EU market. Egypt + Morocco gaining mandarin share at Spain's expense.
EU progressively tightening Maximum Residue Limits for post-harvest fungicides (imazalil, thiabendazole). Border interceptions rising. Compliance costs higher for producers using older active ingredients.
