MEXICO CITY: Claudia Sheinbaum was sworn in as Mexico`s first woman president on Tuesday, taking the reins at a time the country is struggling with violence from organised crime and a hefty deficit in Latin America`s No 2 economy.

Sheinbaum, the 62-year-old scientist and former mayor of Mexico City, was inaugurated in a ceremony in Mexico`s Congress for a six-year term lasting until 2030.

Her supporters chanted `President! President!` and `Long live Mexico!` after Sheinbaum took the oath of office in front of lawmakers. Political watchers and analysts predict Sheinbaum will urgently look to calm investors following the passing of a controversial judicial reform pushed by her predecessor Andres Manuel Lopez Obrador.

Markets will be looking to Sheinbaum for `a predictable and investment-friendly policy and regulatory framework,` said Alberto Ramos, head of Goldman Sachs Latin American economic research.

`Disciplined management of the budget and of state-owned enterprises, progress on public security, and safe-guarding the integrity of key institutions will be key to preserving market sentiment and sovereign debt ratings,` Ramos said, emphasising the importance of state energy firm Petroleos Mexicanos (Pemex).The November presidential elections in the United States, Mexico`s largest trading partner, could add to market volatility, especially if former President Donald Trump, who has vowed to increase tarif fs on Mexican goods, wins. Sheinbaum`s government will present its first budget before Nov 15, which is expected to be highly scrutinised for clues on whether Sheinbaum will make good oncommitments to reduce the fiscal deficit to 3.5 per cent of gross domestic product from 5.9pc, where it is predicted to close the year.

Continuity with change? Lopez Obrador, whose six-year term began in 2018, managed to double Mexico`s minimum wage, reduce poverty and unemployment, broaden the base of social programmes and oversee a previous strengthening of the peso. Touting these successes boosted his popularity and helped usher Sheinbaum, his protege, to a landslide victory in the June elections.

Sheinbaum, however, who has promised `continuity with change,` will inherit the largest budget deficit since the 1980s and lagging economic growth. Experts have said Mexico`s economy will require a tax reform to increase revenues, though Sheinbaum has said publicly she does not plan a sweeping tax overhaul.

Instead, she has said she will pursue other options, including improving the efficiency of tax collection at customs.

Sheinbaum `will have to deliver an important fiscal consolidation if she wants to keep the positive view that markets have today towards her,` said Bernardo Keiserman, an economist at investment bank Bradesco BBI.-Reuters
