Since Chile’s return to democracy in 1990, power passed predictably between centre-left and centre-right coalitions — a model credited with stability even as it locked in deep inequalities. But over the past decade, that equilibrium has cracked. Crime surged, growth stalled, the constitutional process dragged on and trust in political elites collapsed. By the time Chileans headed into the 2025 elections, the old script had fallen apart and the political landscape had fractured into something far noisier and far less predictable.

Against this backdrop came one of the most consequential elections since Chile’s return to democracy. Two rounds — 16 November and 14 December — culminated in a decisive runoff where far-right Republican Party candidate José Antonio Kast trounced leftist Jeannette Jara with roughly 58% of the vote. It was a landslide, a sharp turn to the right and the clearest mandate Chile has delivered in years.

Now, Kast marches toward La Moneda promising order and clarity in a time of turbulence. His victory reflects a hunger — among many voters — for security, decisiveness and fewer surprises. But expectations collide with uncertainty: the instincts that will shape his early decisions, the pressures waiting in Congress and the shifts he appears ready to make at home and abroad all set the stage for a presidency that could recalibrate the country’s direction in ways both immediate and far-reaching. 

Kast, Ideology and the “Emergency Presidency”

According to a senior advisor from Chile’s public electoral institution, Kast arrives with a clearly defined ideological toolkit: law and order, tough borders, moral conservatism and economic liberalism. It’s a combination he’s packaged as the antidote to years of drift — and one he claims will underpin an “emergency government”. That branding sets the bar high, perhaps inconveniently so, should reality decline to cooperate. 

Though Kast has served several terms in parliament, two political sources — one from the right and the other from the centre-right — noted that he has relatively little experience leading a broad political movement. Translation: Chile now has a president whose future governing style is something of a mystery box. The centre-right politician added that Kast’s rhetoric has already undergone a quiet evolution — from doctrinaire chest-thumping to a more strategic, interest-driven tone tailored to voters fed up with administrative misfires. 

Still, not everyone is convinced this pragmatic streak is here to stay. A seasoned political activist warned that the behaviour of Kast’s party during the second Constitutional Convention — described as rigid and polarising — suggests that ideological flexibility may evaporate once hard choices hit the desk. Reinforcing this caution, the politician noted Kast’s long-standing admiration for Jaime Guzmán and the 1980 Constitution, arguing that this makes it improbable he ever truly sought a new charter unless it echoed his own convictions. 

Shock Therapy and Steady Hands

Kast’s early programme reads like a three-course meal for impatient voters. As the senior electoral advisor put it: first, a security shock; second, an economic adjustment centred on spending cuts, deregulation and lower corporate taxes; and third, a slow but deliberate move on socially conservative reforms. 

A right-wing politician (from outside Kast’s party) suggested that the president-elect is keen to distinguish himself from the outgoing government by avoiding early ideological fireworks and focusing on anti-crime efforts — territory where he enjoys broad public backing. In other words, no big-bang social agenda in the first hundred days, just a heavy emphasis on law, order and fewer unpleasant surprises on the nightly news. 

Economic decisions, meanwhile, are expected to revolve around his advisers, especially Jorge Quiroz — described by one political source as “Kast’s most important adviser” on what is considered the administration’s top priority alongside security. The message coming from the campaign is simple: revive the economy and you weaken the insecurity-poverty feedback loop. 

Security remains the philosophical core of Kast’s project. The electoral campaigner claimed this stems from a worldview in which “the left has sought to foster violent environments to secure power.” As a result, Kast’s advisory circle includes retired military and naval officers as well as security professionals. These figures provide ballast alongside political lieutenants such as Arturo Squella and policymakers like Ricardo Irarrázabal, who are tasked with designing the regulatory tweaks needed to unfreeze stalled investments. 

Reviving key sectors is part of the sales pitch. According to a senior advisor, Kast intends to boost mining, energy, infrastructure and the growing security and surveillance technology industry — basically, anything that can restart investment flows. The early risks, however, are significant: rising migration pressures, potential social unrest linked to tighter budgets, and the simple institutional reality, highlighted by one political source, that Congress will require negotiation at every stage. Kast’s bloc does not command a majority in an already fragmented legislature, making cross-party agreements unavoidable.

A former member of Congress noted that global markets have already responded positively to Kast’s win, with expectations running high for early growth-boosting measures. 

One of Kast’s favoured instruments is administrative acceleration. As the centre-right politician explained, Kast has argued repeatedly that “much of the executive’s work does not need to go through Congress,” which didn’t exactly thrill left-wing legislators. They promptly accused him of wanting to “govern by decree.” The source, however, interpreted this less as a power-grab and more as a critique of state agencies that routinely blow past deadlines when evaluating major investment projects. 

Friends, Frenemies and the PDG

Of course, even the most energetic executive still needs Congress, and Kast’s coalition is well short of a majority. The senior electoral advisor described his likely approach as a patchwork of tactical alliances — primarily with Chile Vamos, a centre-right coalition that includes liberal-conservative and Christian-democratic factions, and the flamboyantly unpredictable Partido de la Gente (“PDG”), a populist, ideologically eclectic party focused on anti-establishment messaging.

The centre-right politician noted that Kast must convince the PDG that standing with the government comes with actual rewards. Yet they also doubted the PDG would swing leftward, given the left’s current discredit in public opinion. The politician highlighted the historically low vote share of the Communist Party’s presidential candidate — a result they argued reflects the damage done by the outgoing administration. 

Diplomatic Whiplash

Foreign policy may be the area where Kast’s victory generates the sharpest pivot. As the centre-right politician commented, any discussion must begin with the state of the outgoing government’s external relationships. The experienced campaigner went further, arguing that the administration exiting La Moneda has inflicted “enormous” damage on ties with the United States, Israel, the United Kingdom, Spain, Russia, China, Venezuela and, before that, Brazil. 

Kast is expected to realign Chile’s foreign policy with the same clarity he promises at home. A senior advisor noted that he would likely join a conservative hemispheric axis (with Milei’s Argentina and a potential future Trump administration), adopt a hard line on Venezuela, Cuba and Nicaragua and cool relations with progressive governments such as Brazil and Mexico.  

A former member of Congress projected smoother relations with Argentina under Milei, strengthened ties with the United States and Israel, and generally warmer links with right-leaning governments in Europe and beyond. Together, these views point to a foreign-policy redirection anchored in ideological affinity and a desire to mark a decisive break from the orientation of Boric’s outgoing administration. 

Kast’s presidency places security, market-friendly reforms and conservative values at the heart of Chile’s political agenda. His leadership may blend firm ideological conviction with moments of tactical pragmatism, shaped by influential advisers and hemmed in by a fractious Congress. Internationally, he appears poised to re-anchor Chile among right-leaning governments. Whether this project brings stability or fresh turbulence will depend on how successfully he turns the spirit of an “emergency government” into actual governance, and one that moves quickly without losing the art of democratic negotiation.
