## Argentina Power Structure
Argentina is a federal presidential republic where the president, 23 governors and the Buenos Aires City head of government share real power.
## Why it Matters
President Javier Milei controls the executive but lacks a congressional majority, so governors and centrist legislators decide which reforms become law.
## Key Numbers
Milei met 13 governors and provincial leaders in Paris on 1 October 2026 to seek support for the 2027 budget and electoral reform.
## Who Holds Power
Karina Milei organises the ruling party, Diego Santilli negotiates with Congress, and Luis Caputo runs the economy as of September 2026.
## The Catch
The opposition is fragmented among Peronists, Kirchnerists and provincial leaders, which helps Milei but also makes every major vote unpredictable.
## What It Means for You
Foreign investors and expats should watch governors and Congress, not just the president, because provincial support often decides whether economic reforms survive.
## The President
Javier Gerardo Milei is Argentina’s president and head of state and government. He took office on 10 December 2023 and leads the libertarian La Libertad Avanza administration.
## Karina Milei
Karina Elizabeth Milei, the president’s sister, is Secretary General of the Presidency and one of the most influential figures in the administration.
## Diego Santilli
Diego César Santilli is Chief of the Cabinet of Ministers. He took the oath on 30 June 2026 and previously served as Minister of the Interior and as a national legislator.
## The Economic Team
Milei’s political credibility is closely tied to inflation, the exchange rate, public finances and the availability of foreign currency.
## Luis Caputo
Luis Andrés Caputo is Minister of Economy. His portfolio covers fiscal policy, debt management, tax policy, exchange-rate policy, relations with international lenders, and investment and privatisation policy.
## The Ruling Party
La Libertad Avanza is the governing force, created around Milei. Its political identity is built around Milei’s personal leadership, economic liberalisation, anti-establishment rhetoric, opposition to Peronism, fiscal austerity, a smaller state and strong executive direction.
## The Opposition
Argentina’s opposition is fragmented rather than unified. Its main components are Peronist or Kirchnerist forces, provincial parties, centrist legislators and parts of the traditional centre-right.
## Axel Kicillof
Axel Kicillof is governor of Buenos Aires Province, Argentina’s largest and most politically consequential province. His government is a principal institutional counterweight to Milei.
## Governors
Argentina is a federal country, and governors hold substantial political leverage. They control provincial administrations, influence national legislators elected from their districts and can determine whether the president’s bills pass Congress.
## What to Watch
The most important near-term question is whether Milei can pass the 2027 national budget. That vote will test his ability to hold together the coalition of governors and centrist legislators he has been courting.
## Key takeaway

Argentina's president Javier Milei controls economic policy but requires governors and centrist legislators to pass reforms due to fragmented opposition.
