Which elections could disrupt business in October 2026?
Brazil holds its General Elections on 04 October, with a runoff on 25 October if no candidate wins outright, to elect the President and Vice President, state governors, two-thirds of the Federal Senate and all 513 seats in the Chamber of Deputies. Twelve presidential candidacies are registered, with attention concentrated on incumbent Luiz Inácio Lula da Silva (PT) against Bolsonaro-aligned Senator Flávio Bolsonaro (PL), amid sharp political polarisation; expect demonstrations around campaign events and after results are released, plus localised traffic and security measures near polling stations. The same day, Peru holds nationwide Regional and Municipal Elections, with more than 26.3 million citizens eligible to vote across over 10,000 polling locations — temporary congestion is expected near polling sites, with disruption normalising once counting concludes. Quebec held a provincial election on 05 October following September developments, and in the US, campaigning intensifies throughout October ahead of the 03 November midterms, in which all 435 House seats and roughly a third of Senate seats are contested.
What should businesses expect around Columbus Day on 12 October?
12 October marks the anniversary of Columbus’s 1492 arrival in the Americas and has increasingly become associated with Indigenous-rights demonstrations and anti-colonial mobilisation rather than purely commemorative events. In Chile, Mapuche organisations, students and human rights activists are expected to march in Santiago along Avenida Libertador General Bernardo O’Higgins, with similar activity in Temuco, Concepción and Valparaíso. Ecuador observes Día de la Interculturalidad y Plurinacionalidad, with CONAIE-organised assemblies expected in Quito and provinces including Imbabura, Cotopaxi and Azuay. In Mexico, demonstrations addressing Indigenous rights and related grievances are expected to concentrate along Paseo de la Reforma in Mexico City, with further activity in San Cristóbal de Las Casas, Oaxaca City and Guerrero. In the US, parallel Columbus Day and Indigenous Peoples’ Day observances can produce competing public gatherings in New York City, Washington DC, Chicago, Minneapolis, Denver and San Francisco, alongside traditional Italian-American parades such as New York’s Fifth Avenue procession.
What major events and campaign activity should businesses track?
The Bank of America Chicago Marathon on 11 October is expected to draw approximately 50,000 participants and more than one million spectators, with extensive road closures across downtown Chicago and 29 neighbourhoods beginning as early as 0500 hours. Nationwide “No King: Early Vote” rallies are planned across the US on 17 October, focused on voter mobilisation ahead of the midterms, with potential for localised traffic congestion and heightened police presence, particularly in Boston and other urban centres; activist organisations have signalled readiness to respond further if disputes emerge over voting procedures. In Jamaica, Kingston’s BZR Weekend (16–19 October), part of the Heroes Weekend period, is expected to draw more than 50,000 patrons for a four-day entertainment programme including an 18 October Cardi B concert at the National Stadium, with increased traffic, accommodation demand and localised access restrictions around venues. Canada observes Thanksgiving nationwide on 12 October, with increased domestic travel and retail activity expected over the long weekend.
What risks are carrying over from September?
Bolivia’s Plurinational Legislative Assembly extended the country’s state of exception by 90 days to 17 December, following road blockades earlier in the year that caused an estimated BOB 14 billion in losses; renewed mobilisation risk is expected to rise in December as scheduled fuel-subsidy removal approaches. Canada’s retaliatory tariffs on US goods, covering roughly CAD 27.6 billion in imports across sectors including steel, aluminium, dairy and electronics, took effect 08 September and remain a live cost and supply-chain planning factor. Wildfires remain active across the US Northwest and Rocky Mountains, Canada, Brazil’s Amazon, Cerrado and Pantanal regions (in peak season through October), and Colombia, where a public calamity was declared near Villa de Leyva. Hawaii’s Kīlauea volcano continues intermittent summit fountaining following heightened activity on 13 September, with vog and ash-dispersion contingency planning advised for air carriers and logistics operators.
What should businesses do to prepare?
Organisations with operations in Brazil or Peru should monitor polling-day logistics and avoid assumptions about outcomes until results and any runoff are confirmed. Businesses with US exposure should track midterm campaign activity and the 17 October rally dates in cities where they have offices or travelling staff, and maintain flexible travel arrangements around Columbus Day demonstrations in Chile, Ecuador, Mexico and the US. Firms with Canada-US trade exposure should review tariff classifications and supplier arrangements against the new counter-tariff schedule, and those with Bolivia, Brazil, Colombia or Hawaii operations should maintain contingency plans for blockade, wildfire-smoke and volcanic-ash disruption respectively.
