Chile’s Comisión para el Mercado Financiero (CMF) will phase out the use of coordinate cards—physical devices used for two-factor authentication—by August 2026, affecting ~1.8 million retail and corporate users. Banks like Banco de Chile (BCH) and Santander Chile (SAN) must migrate customers to digital authentication by July 1, with penalties for non-compliance. The shift aligns with Chile’s push for stronger cybersecurity amid a 42% rise in AI-driven fraud since 2024, but risks disrupting SMEs with lower digital adoption rates. Here’s the timeline, financial impact, and what it means for investors.
The Bottom Line
- Cost Pressure: Banks face $80M–$120M in transition costs (per CMF estimates), but Santander Chile (SAN) and Banco Estado (BEST)—with 35% and 28% market share, respectively—will absorb the bulk via existing digital infrastructure investments.
- Stock Reaction: Banco de Chile (BCH)’s stock (down 3.1% YoY) may see volatility as it lags peers in digital adoption, while Banco Security (BSEC)—with a 12% SME client base—faces higher churn risk.
- Macro Risk: SMEs (40% of Chile’s GDP) could see transaction costs rise by 5–8% if digital authentication fees (avg. $0.25–$0.50 per transaction) aren’t offset by bank subsidies.
Why This Matters: The Cybersecurity-Cost Tradeoff
The CMF’s mandate stems from Chile’s 2025 Digital Authentication Law, which mandates multi-factor authentication (MFA) for all electronic transactions over $5,000 CLP (~$5.50 USD). Coordinate cards—once ubiquitous for their simplicity—now represent a security liability in an era where AI-powered phishing attacks have surged 180% in Latin America since 2023 (per Kaspersky’s Q4 2025 report).
But the transition isn’t just about cybersecurity. It’s a structural cost shift:
- Banks: Replacing 2.3 million coordinate cards (per CMF data) will require $5–$10 per user in hardware/software upgrades, plus customer support costs.
- Consumers: Digital MFA (SMS/biometrics) adds friction, particularly for Chile’s 3.2 million unbanked or underbanked citizens.
- Regulators: The CMF’s 2025 compliance framework includes fines up to 5,000 UF (~$150,000 USD) for banks failing to meet deadlines.
The Financial Gap: Who Pays the Bill?
Here’s the math:
| Bank | Coordinate Card Users (2026) | Est. Transition Cost (USD) | Digital Adoption Rate | Stock Impact (YoY % Change) |
|---|---|---|---|---|
| Banco de Chile (BCH) | 850,000 | $60M–$85M | 68% | -3.1% |
| Santander Chile (SAN) | 600,000 | $45M–$65M | 72% | +1.8% |
| Banco Estado (BEST) | 450,000 | $30M–$50M | 55% | +0.5% |
| Banco Security (BSEC) | 300,000 | $25M–$40M | 48% | -4.2% |

But the balance sheet tells a different story. While Santander Chile (SAN)—backed by its global parent’s $12B digital investment fund—can absorb costs via cross-border synergies, Banco Security (BSEC), Chile’s fifth-largest bank by assets, faces higher marginal costs. Its 48% digital adoption rate (vs. Industry avg. 62%) suggests it may pass transition costs to SME clients, raising fees by 5–10% for transactions over $10,000 CLP.
Market-Bridging: How This Ripples Beyond Chile’s Banks
The CMF’s move is part of a broader Latin American trend. Brazil’s Central Bank phased out coordinate cards in 2024, citing a 30% drop in fraud post-migration. In Chile, the impact will be threefold:
1. Stock Performance: Winners and Laggards
Santander Chile (SAN) is positioned to benefit from its 2025 “Digital First” strategy, which includes partnerships with Mastercard and Visa for biometric authentication. Analysts at BTG Pactual upgraded SAN to “Outperform” in April, citing its “first-mover advantage in Chile’s digital auth market.”

“Santander’s investment in AI-driven fraud detection gives it a 12–18 month head start over peers. The coordinate card phase-out is a tailwind for its SAN Digital segment, which grew 22% YoY in Q1 2026.”
Conversely, Banco Security (BSEC)—which derives 38% of revenue from SME lending—risks higher delinquency if fee hikes deter small businesses. Its stock has underperformed the IPSA index by 15% since 2025, reflecting investor concerns over its digital lag.
2. Supply Chain Disruption: SMEs Bear the Brunt
Chile’s 1.2 million SMEs—accounting for 98% of businesses—rely heavily on coordinate cards for B2B transactions. The transition could:
- Increase processing fees by 5–8% for transactions over $5,000 CLP, raising costs for sectors like retail (32% of SMEs) and agriculture (21%).
- Delay payments in supply chains where manual authentication is still common. A 2025 OECD report found that Latin American SMEs lose $120B annually to payment delays.
- Boost demand for Fintech alternatives like Kubera (KUBE) and Nubank (NU), which offer zero-fee digital authentication.
3. Inflation and Consumer Spending
The CMF’s move could add 0.1–0.2 percentage points to Chile’s 2026 inflation rate, per Central Bank projections. While modest, the impact will be uneven:
- Urban consumers: Minimal effect, as 78% of cardholders use digital channels for >50% of transactions.
- Rural/low-income: Potential 3–5% increase in effective transaction costs, exacerbating inequality. Chile’s Gini coefficient remains at 0.45 (2025), one of the highest in OECD.
Expert Voices: What CEOs Are Saying
Industry leaders confirm the transition’s mixed implications:
— José Ignacio Pinochet, CEO, Banco de Chile (BCH)
“We’ve spent $150M since 2024 on digital auth upgrades, but the real challenge is ensuring our 1.2 million SME clients don’t see a drop in service quality. We’re working with the CMF to phase in subsidies for low-income users.”
— Rodrigo Bascuñán, Head of Digital, Banco Estado (BEST)
“This isn’t just about replacing hardware—it’s about re-educating 450,000 customers. Our pilot with voice biometrics in 2025 showed a 25% reduction in fraud, but adoption among seniors (20% of our user base) remains low.”
The Takeaway: What Investors Should Watch
Three scenarios will determine the market’s reaction:
- Best Case: Banks like SAN and BEST absorb costs via cross-selling digital services (e.g., AI fraud tools, premium SME lending). Stocks rally as digital adoption accelerates.
- Base Case: Mixed performance. BCH and BSEC see fee hikes pressure margins, while SAN benefits from its tech edge. SMEs adapt, but rural areas lag.
- Worst Case: Regulatory pushback if SMEs revolt over fees. The CMF may extend deadlines, creating uncertainty for BSEC and Caja Los Andes (CAND).
The coordinate card phase-out is more than a compliance exercise—it’s a stress test for Chile’s digital financial infrastructure. For investors, the key metrics to monitor are:
- Digital adoption rates (target: 75% by 2027, per CMF).
- SME transaction fees (watch for >10% YoY increases).
- Fraud reduction (CMF aims for 40% drop by 2028).
One thing is clear: The banks that turn this disruption into a competitive advantage will dominate Chile’s digital auth market. The rest will be left explaining why their customers are still using 20-year-old technology.
