Mexico’s Inflation Breaches Banxico’s 4% Ceiling as Oil Shock Constrains Rate Path; IEA Releases Record 400 Million Barrels but Iran Threatens $200; Defending Champions Botafogo Eliminated from Libertadores by Ecuador’s Barcelona SC; Banco Master CPI Heads Toward Congress–STF Confrontation; Colombia’s Final Tally Confirms Centrist Kingmaker Bloc
Executive Summary
The Big Picture: This is part of The Rio Times’ comprehensive coverage of Latin American financial markets and economic developments. Mexico’s inflation breached Banxico’s 4% ceiling in February—jumping to 4.02% from 3.79%—just as the Hormuz oil shock threatens to add further energy-driven pressure to consumer prices across the hemisphere. The reading constrains Banxico’s easing cycle at precisely the moment when the USMCA summer renegotiation demands economic stability. Meanwhile, the IEA on Wednesday confirmed the largest-ever release of emergency oil reserves—400 million barrels from 32 member states—though IEA chief Birol warned that reserves cannot substitute for the resumption of transit through the Strait, and Iran threatened to push crude to $200. On the continent floor, defending Libertadores champions Botafogo were eliminated by Ecuador’s Barcelona SC in one of the biggest upsets in the tournament’s recent history. Brazil’s Banco Master CPI moved closer to a direct confrontation between Congress and the Supreme Court. Colombia’s centrist kingmaker bloc consolidated its grip on the next government’s legislative arithmetic. And in Santiago, Kast completed his first day in office with a crime-first inaugural address—”anyone who attacks a Carabinero attacks all of us”—$6 billion in spending cuts over 18 months, and a 3% across-the-board ministry reduction, while deliberately saying nothing about his moral agenda on abortion, divorce, or LGBTQ rights.
Mexico’s February CPI at 4.02% breached Banxico’s 2%–4% target range for the first time since late 2025, driven by persistent services inflation at 7.68% and rising food prices. The oil shock adds a second inflationary channel: the Hormuz crisis has pushed global energy benchmarks well above the levels assumed in Banxico’s December projections, even after this week’s pullback. Banxico had been on a measured easing cycle—cutting rates to 7.25% in December—but the combination of above-target inflation and energy uncertainty may force a pause at the next decision. The USMCA public consultation summary, released this week, signals active preparation for the summer renegotiation, adding trade uncertainty to the macro picture. The CJNG succession crisis continues as the dominant security challenge.
Brazil’s Banco Master scandal continued to escalate as the CPI do Crime Organizado pressed its appeal to the STF to compel Vorcaro’s testimony. The separate CPI targeting Supreme Court justices’ links to the bank now has 35 signatures—well above the threshold—but Senate President Alcolumbre has not yet formally opened it. The opposition PL has filed a parallel inquiry in Brasília’s legislative chamber. The convergence of multiple investigative fronts is heading toward a constitutional standoff between legislative and judicial power that could reshape the 2026 electoral landscape. The Copom meets in five days with the Selic at 15.00%.
Colombia’s definitive vote-by-vote tally is under way this week and will determine final seat allocations that could shift by one or two seats per party. The centrist bloc’s 47 senators and 8.5 million votes make it the decisive force for any future government. Analyst Boz Substack noted that “the Colombian presidential race is not simply Cepeda vs de la Espriella”—Valencia’s primary victory and Oviedo’s surprise performance have created a genuine three-way dynamic on the right alone. Whether Valencia and Oviedo formalise an alliance is the immediate strategic question.
Argentina’s Milei attended Kast’s inauguration in Santiago on Wednesday after concluding Argentina Week in New York, where his government presented nuclear industry investment opportunities to over 50 U.S. companies. The Milei–Kast relationship is now formalised at the presidential level, with both leaders sharing an agenda on security, migration, and economic liberalisation. Argentina’s MERVAL extended its rally for a second consecutive session as financial stocks continued to recover.
Mexico’s economy ministry’s USMCA public consultation summary, released Monday, signals that the government is actively preparing for the summer renegotiation deadline—the most consequential bilateral economic test of Sheinbaum’s presidency. The CJNG succession crisis continues to generate factional violence across multiple states. The screwworm crisis in Chiapas remains unresolved, with a fly-production facility approximately two months from completion.
Regional Mood
Mexico’s 4.02% inflation print is the canary in the mine for the hemisphere: if the oil shock pushes above-target inflation in an economy that was already weakening, the same dynamic will ripple through every Latin American central bank decision this quarter. Banxico, Copom, and BanRep all face the same bind—weak growth arguing for easing, rising prices arguing for caution—and the Hormuz crisis has tipped the balance toward hawkishness at precisely the wrong moment. The IEA’s 400-million-barrel reserve release buys time but cannot reopen the strait. Kast’s first day in office in Santiago delivered exactly what he promised—crime first, austerity fast, moral agenda deferred. His speech was a law-enforcement loyalty pledge: expanded police powers, stricter sentencing, border enforcement, and a vow to prosecute anyone who targets a Carabinero. Not a word about abortion, divorce, or LGBTQ rights—issues he has fought on for decades—because he needs the centrist People’s Party to legislate and cannot afford a culture war on day one. Finance Minister Quiroz’s $6 billion spending cut over 18 months and 3% across-the-board reduction make the fiscal intent unmistakable. U.S. Ambassador Judd’s comment that trade with China is “fine” but critical infrastructure “concerns us” gave Kast the diplomatic framework to renegotiate the cable without a full break with Beijing. Whether he uses it—and what Beijing demands in return—is the first real test of the new government. But the IPSA’s inauguration-day decline signals that markets wanted substance on the cable, not rhetoric on Carabineros. Brazil’s Banco Master CPI is heading toward a Congress–STF confrontation that could define the October election. Colombia’s centrist kingmaker bloc is quietly becoming the most consequential political force in South American politics. And in the background, Botafogo’s Libertadores elimination by Ecuador’s Barcelona SC—with 18% possession over 90 minutes—is a reminder that underdogs with discipline can upset the hemisphere’s establishment across every domain.

Mexico
February inflation breaches Banxico’s 4% ceiling; oil shock adds second price channel; USMCA review accelerates; CJNG succession crisis grinds on
What Happened
- —Inflation breach: Mexico’s annual inflation rate rose to 4.02% in February from 3.79% in January, breaching the upper bound of Banxico’s 2%–4% target range for the first time since late 2025. Services inflation—the component Banxico watches most closely—remains stubbornly elevated at over 7%, driven by restaurant prices, mobile phone services, and packaged tourism. Food, beverages and tobacco inflation accelerated to 4.43%. The reading came in above market expectations and reverses the disinflation trend that had allowed Banxico to cut rates through 2025.
- —Oil shock transmission: The Hormuz crisis adds a second inflationary channel that was not present when Banxico last decided rates in December. Although Brent pulled back from Monday’s $119 spike to the mid-$80s by Wednesday, global energy benchmarks remain well above the levels assumed in Banxico’s December projections. Mexico is a net oil producer through Pemex but also a significant importer of refined products, making the price transmission complex. BBVA Research had already warned before the oil shock that Banxico would likely “move to the sidelines” after one final cut, citing persistent core inflation in services.
- —USMCA preparation: Mexico’s economy ministry released a public consultation summary this week on the upcoming USMCA review, signalling active preparation for the summer renegotiation deadline. The review is the most consequential bilateral economic test since Sheinbaum took office. Trump has repeatedly used trade policy as a coercive tool—threatening tariffs up to 100% on countries that deepen China ties—transforming what should be a technical review into a geopolitical negotiation.
- —Security: The CJNG succession crisis following El Mencho’s February 22 killing continues to generate factional violence across multiple states with no clear new leadership structure emerging. Sheinbaum’s sovereignty framework—bilateral cooperation without military subordination—held through last week’s Doral confrontation but faces continuous testing as cartel fragmentation produces unpredictable security dynamics.
Why It Matters
The 4.02% reading puts Banxico in a bind that mirrors central bank dilemmas across the hemisphere. The economy is weak—domestic demand contracted through late 2025—which argues for continued easing. But inflation is accelerating above target with an energy shock on top, which argues for caution. The Rio Times’ Global Economy Briefing noted that “the previous day’s hot Mexican CPI data continued to frame the regional narrative” and that Banxico’s rate path “has become more constrained.” BBVA Research’s December assessment that Banxico would deliver “one last rate cut before moving to the sidelines” now looks prescient, though even that final cut may be in doubt if energy prices remain elevated.
The USMCA review adds a structural dimension. Mexico’s entire economic model since 1994 depends on preferential access to the U.S. market. Trump’s willingness to use tariffs as foreign policy—50% on steel and aluminium already in effect, 100% threatened if Mexico deepens China ties—transforms the review from a technical exercise into a sovereignty negotiation. Sheinbaum has positioned Mexico as cooperating on security but independent on economic policy; whether that distinction survives the USMCA review is the question of the summer. Inflation above 4% weakens her hand by signalling economic fragility at precisely the moment she needs to project strength.
Key Watch
Banxico’s next rate decision and whether 4.02% forces a pause. Oil price pass-through to Mexican pump prices and consumer inflation. USMCA review timeline and U.S. demands. CJNG succession—whether a new leader consolidates or fragmentation accelerates. World Cup security preparations and Trump’s immigration raid posture.
RISK: ELEVATED
What Happened
Brazil
Banco Master CPI advances on multiple fronts; Congress–STF confrontation building; Copom in five days; October election shadow lengthens
What Happened
-
-
- —Multiple investigative fronts: The Banco Master scandal is now being pursued on at least three simultaneous tracks: the CPI do Crime Organizado (which appealed to the STF to compel Vorcaro’s testimony), the proposed new CPI specifically targeting justice–banker links (35 senators signed), and the PL’s parallel inquiry in Brasília’s legislative chamber targeting the aborted BRB-Master acquisition. Justice Toffoli restricted CPI access to Banco Master documents, arguing that premature disclosure could compromise Federal Police investigations—a ruling the Senate views as obstruction.
- —Institutional stakes: The core allegations are that Supreme Court justices de Moraes and Toffoli had financial relationships with banker Vorcaro, whose R$41 billion bank collapse has produced 1.6 million creditors. Justice Moraes’s wife’s law firm signed contracts with Banco Master. Vorcaro was re-arrested March 4 for allegedly bribing two central bank officials and threatening a journalist. His brother-in-law was arrested separately in Operation Compliance Zero. Senate CPI President Contarato declared the commission “will follow its constitutional mission to investigate and clarify the facts.”
- —Electoral dimension: Covington & Burling’s analysis warned that the scandal “might impact the October 2026 presidential election” and that “developments in the investigation related to members of his cabinet and party might result in a higher electoral cost” for Lula. Lula is currently leading polls by a narrow margin, with São Paulo Governor Tarcísio de Freitas emerging as the right-wing challenger.
-
Why It Matters
The Banco Master scandal is accelerating toward a constitutional confrontation that Brazil’s institutions were not designed to resolve cleanly. When a congressional inquiry targets the very court that rules on the legality of congressional inquiries, the system encounters a structural paradox. Toffoli’s restriction of CPI access to documents, Mendonça’s ruling making Vorcaro’s testimony optional, and the Senate’s appeals challenging both decisions represent the opening moves of a separation-of-powers crisis that could define Brazilian politics for years.
The Copom meets March 17–18, and the Hormuz oil retreat has marginally improved the inflation outlook. But the institutional backdrop is what matters for medium-term market confidence: if the scandal escalates into a full Congress-versus-STF standoff before October, investor calculus must factor in regime uncertainty alongside the usual macro variables. The parallel to Lava Jato is imperfect but instructive—that scandal reshaped Brazilian politics for a decade. Whether Banco Master has similar force depends on whether the allegations against the justices are substantiated, and whether the political system allows the investigation to proceed.
Key Watch
Whether Alcolumbre formally opens the Supreme Court CPI. STF ruling on Vorcaro compulsion. Copom March 17–18 rate decision. Whether Moraes/Toffoli allegations produce new evidence. Lula’s polling trajectory as scandal developments intensify. Tarcísio de Freitas’s response and positioning.
RISK: ELEVATED
Colombia
Final vote tally under way; centrist bloc consolidates as hemisphere’s quiet powerbroker; Valencia–Oviedo alliance and the three-way right reshape the presidential race
What Happened
-
-
- —Final count: Electoral authorities are conducting the definitive vote-by-vote tally that will determine final seat allocations, with results expected this week. Preliminary counts give the Historic Pact 62 total congressional seats (25 Senate, ~40 House), the Democratic Center 45 (17 Senate, 28 House), with traditional parties—Liberals, Conservatives, Green Alliance, Party of the U—controlling the centrist balance. Final numbers may shift by one or two seats per party.
- —Centrist kingmaker: The Conservatives, Liberals, and Party of the U collectively control 47 senators and drew 8.5 million votes—making this centrist bloc the decisive force for any future government. Analyst Sergio Guzmán of Colombia Risk Analysis described a Congress where “relatively ideological extremists lead the presidential race, while a strong moderate coalition leads the legislative vote.” This bloc will determine whether any president can pass legislation, reform the constitution, or approve cabinet appointments.
- —Right reshuffled: The presidential field has been fundamentally altered. Valencia’s 3.2 million primary votes make her the conservative standard-bearer, but Oviedo’s surprise 1.25 million introduce a genuine alternative. De la Espriella’s party drew only 600,000 votes, leading multiple analysts to describe his candidacy as “shaky.” Whether Valencia and Oviedo formalise an alliance—their combined 4.5 million would create a formidable ticket—is the immediate strategic question. Cepeda remains the left’s polling leader but now faces a more credible right-of-centre challenge than anticipated.
-
Why It Matters
Colombia’s centrist bloc is quietly becoming the most consequential political force in South America. Unlike the ideological poles—Petro’s Historic Pact on the left, Uribe’s Democratic Center on the right—this bloc has no single leader, no presidential candidate, and no unifying ideology beyond institutional pragmatism. Yet it controls the legislative balance. Any president elected on May 31 will govern through this centre or not at all. The fragmentation ensures that Colombia will not experience either a Petro-style reform acceleration or a populist constitutional rewrite—the moderates will block both.
Uribe’s absence from the Senate removes the right’s most experienced—and most polarising—legislative operator. Valencia inherits his party but not his baggage, which could prove liberating in a general election where swing voters recoil from extremes on both sides. The Trump administration’s posture is the external variable: Rubio’s longstanding ties to Uribe and the CPAC network suggest Washington may signal a preference for Valencia, but de la Espriella’s social media operation and Bukele-style branding appeal to a different constituency within the Trump orbit. The May 31 first round is 80 days away and the field is more open than any Colombian presidential race in a generation.
Key Watch
Final tally results this week. Valencia–Oviedo alliance formalisation. De la Espriella’s next move—dropout or double-down. Cepeda’s coalition-building with centrist parties. Petro’s constitutional rewrite push and whether it gains traction. Washington’s preferred candidate signal. First post-election polling.
RISK: ELEVATED
Regional Snapshot

Chile Kast was inaugurated yesterday in Valparaíso with Senate President Paulina Núñez placing the presidential sash. His speech centred on crime: “Anyone who attacks a Carabinero attacks all of us.” Finance Minister Quiroz announced $6 billion in spending cuts over 18 months with an immediate 3% across-the-board reduction. U.S. Ambassador Judd stated that Washington does not oppose trade with China but is concerned about critical infrastructure—the clearest public framing of the cable red line. FM Pérez Mackenna, Security Minister Steinert, and Justice Minister Rabat were confirmed. Kast moved into La Moneda—the first president to reside there since the 1950s. The IPSA fell on inauguration day as austerity and cable uncertainty weighed. |
Cuba The humanitarian crisis deepened as UPI reported HIV patients in Havana receiving expired antiretroviral medications from state pharmacies amid supply shortages. The electricity grid remains at roughly 1,000 MW against demand exceeding 3,000 MW, with daily 12–20 hour blackouts the norm. Eight of 16 thermoelectric plants remain offline. The U.S. oil blockade continues without resolution. Air France suspended Havana flights. Trump maintains regime-change framing. The IEA’s global reserve release will not benefit Cuba, which is cut off from conventional oil markets by U.S. sanctions. |
|
Argentina Milei attended Kast’s inauguration in Santiago on Wednesday, formalising the presidential-level relationship between Latin America’s two most right-aligned leaders. During Argentina Week in New York, the government presented nuclear industry investment opportunities to over 50 U.S. companies—a sector-specific pitch reflecting the REGI framework’s expansion beyond energy and mining. The BCRA continues accumulating reserves (over US$2.8 billion in 2026). March inflation is expected around 3%. The six global banks’ sovereign bond exit recommendation has not derailed the Argentina Week narrative but remains a structural counter-signal. |
Ecuador Noboa’s government continues to deepen its alignment with Washington through Operation Southern Spear, now the operational prototype for the Shield of the Americas coalition. The nine-month suspension of opposition party Revolución Ciudadana drew “encroaching dictatorship” accusations from party president Rivadeneira. Cuba’s embassy remains closed following the March 4–6 expulsion. Bolivia presented the five pillars of its anti-drug-trafficking strategy at a UN commission meeting, adding to the regional security architecture that Noboa has positioned Ecuador at the centre of. |
|
Peru The candidate registration deadline is March 14—two days away—for the April 12 general election. The latest Datum poll shows Fujimori at 10.7% and López Aliaga at 10.0%, with 38% undecided among 36 candidates. The ballot reinstates the Senate for the first time since 1992. Interim President Balcázar, the country’s ninth president in a decade, governs until the elected president is sworn in July 28. Security and corruption remain the dominant voter concerns. |
Bolivia Subnational elections on March 22 are 10 days away. The MAS has effectively disappeared from the contest. President Paz’s coalition is fragmented between his partner Doria Medina and VP-turned-opponent Lara. Inflation remains around 23%, dollar shortages persist. Bolivia presented its five-pillar anti-trafficking strategy at the UN Commission on Narcotic Drugs this week, signalling continued alignment with international counter-narcotics frameworks under the post-MAS government. |
