3. Macroeconomic Environment

3.1 GDP and Growth Outlook

Chile's economy is projected to grow 2.0-2.4% in 2026, supported by improving consumer confidence and gradual normalization of monetary policy. The Central Bank of Chile's December 2025 Monetary Policy Report (IPoM) projected growth between 2% and 3%, while the OECD forecasts 2.2% and the IMF projects 2.0%.

Key macro drivers:

• Consumer spending recovery supported by lower inflation and gradual real wage improvement
• Investment recovery led by mining (copper prices remain supportive) and energy transition projects
• Fiscal consolidation ongoing, with the government targeting a structural deficit reduction
• External risks from global trade uncertainty and China slowdown weigh on copper demand outlook

3.2 Monetary Policy and Interest Rates

The Central Bank of Chile (BCCh) held the monetary policy rate (TPM) at 5.00% at its March 2026 meeting. Inflation has been on a downward trajectory, expected to reach the 3% target by Q1 2026. The BCCh projects three additional rate cuts through 2026-2027, bringing the TPM to approximately 4.0% (near its estimated neutral rate) by 2027.

Implications for banking:

• Gradual rate cuts should support loan demand recovery, particularly in mortgages and consumer lending
• Net interest margins likely to compress moderately (from ~4.9% to 4.5-4.8%) as the yield curve flattens
• UF-denominated (inflation-linked) loan book repricing will be a headwind as inflation normalizes
• Lower rates positive for asset quality as debt service burdens decrease for borrowers

3.3 Inflation Dynamics

Inflation has decelerated faster than expected, projected to reach the 3% target by the first quarter of 2026 from approximately 3.5% at year-end 2025. This is significant for Chilean banks because a substantial portion of their loan books is denominated in UF (Unidad de Fomento), an inflation-indexed unit of account. As inflation normalizes, the UF-linked income contribution will moderate, creating a headwind for NIM.

4. Regulatory Landscape

4.1 Basel III Full Implementation

Chile completed the phased implementation of Basel III capital and liquidity standards as of December 1, 2025. This is a landmark achievement that brings Chile's banking regulatory framework fully in line with international best practices. Key elements now fully in force:

1. Core equity requirements (CET1): Fully implemented, with systemically important banks subject to additional capital surcharges
2. Countercyclical capital buffer: Active and calibrated by the BCCh
3. Liquidity Coverage Ratio (LCR) and Net Stable Funding Ratio (NSFR): Both fully implemented
4. Leverage ratio requirements: In force across all banks

4.2 Systemically Important Banks (D-SIBs)

The CMF, with the agreement of the Central Bank of Chile, designated six banks as systemically important based on December 2024 data: Banco de Chile, Banco Santander Chile, BCI, BancoEstado, Scotiabank Chile, and Itau Chile. These banks face additional capital buffer requirements (1-2% surcharge) and enhanced supervisory scrutiny.

4.3 Open Finance System (NCG 514)

The CMF's Open Finance System regulation (NCG 514) is set to become fully operational on July 4, 2026. This represents one of the most ambitious open banking frameworks in Latin America, requiring banks to share customer data (with consent) through standardized APIs. The regulation is expected to:

• Increase competition by enabling fintechs to access customer banking data
• Drive digital transformation investment across the banking sector
• Benefit banks with strong digital platforms and API capabilities
• Create new revenue opportunities in data-as-a-service and embedded finance

4.4 Other Regulatory Developments

Additional regulatory changes in the pipeline include:

• Law 21,680 (effective April 2026): New fintech regulatory framework strengthening CMF oversight of non-bank financial services providers
• CMF Financial Inclusion Strategy (launched January 2025): Focused on expanding access and tailoring products for underserved populations
• Sustainable Finance Roadmap: Mandating climate and ESG risk disclosure for banks, insurers, and listed companies

5. Competitive Dynamics and Key Themes

5.1 Digital Transformation Race

Chilean banks are investing heavily in digital transformation, driven by both competitive pressure and the upcoming Open Finance System. Banco Santander Chile has been particularly aggressive, with digital channels now accounting for a significant share of transactions. Banco de Chile has invested in its digital platform while maintaining industry-leading cost efficiency (37.4% cost-to-income ratio). The entry of digital-first competitors like Tenpo Bank and Itau's itu neobank is accelerating innovation.

5.2 Fee Income Diversification

As NIM compression looms, fee income diversification has become a strategic imperative. Banks with strong wealth management, insurance distribution, and transactional banking platforms (particularly in credit card processing) are better positioned to offset margin pressure. BSAC's leadership in credit card purchases (24.2% market share) and current accounts (22.1%) provides a significant fee income advantage.

5.3 Asset Quality Divergence

A notable divergence in asset quality has emerged among the major banks. Banco de Chile leads with a 2.4% NPL ratio and 148% coverage ratio, while Banco Santander Chile's NPL ratio is 3.2% with 114.5% coverage. Mortgage non-performing loans have been a particular pressure point, with BSAC's mortgage impaired ratio rising from 5.4% to 6.3%. Management teams generally expect NPLs to stabilize by H2 2025, with improvement anticipated through 2026 as rate cuts ease borrower debt service burdens.

5.4 Consolidation and M&A

While major consolidation is unlikely in the near term (the last significant transaction was the 2016 Itau-CorpBanca merger), smaller-scale M&A activity remains possible in specialized niches such as wealth management, insurance, and fintech. The Open Finance System may catalyze partnership and acquisition activity as banks seek to bolster digital capabilities.

6. Investment Implications

6.1 Sector Thesis

We rate the Chilean banking sector OVERWEIGHT based on the following drivers:

• Superior profitability: System ROE of ~15.5% significantly exceeds regional peers and developed market averages, with top banks delivering 20%+ returns on equity
• Regulatory strength: Full Basel III implementation provides a robust capital and liquidity foundation, reducing systemic risk premium
• Macro tailwinds: Inflation convergence to target and gradual rate normalization should support loan demand recovery and asset quality improvement
• Structural growth: Open Finance System and digital transformation create medium-term growth opportunities for well-positioned incumbents

6.2 Key Risks

• NIM compression: Rate cuts and inflation normalization will pressure net interest margins, particularly for banks with large UF-linked portfolios
• Political uncertainty: Constitutional reform process and potential pension reform could impact consumer confidence and banking regulation
• External shocks: Dependence on copper exports makes Chile vulnerable to commodity price volatility and China economic deceleration
• Fintech disruption: Open Finance System may erode incumbent market share in payments and consumer lending
• Mortgage asset quality: Rising mortgage NPLs represent a pocket of risk, particularly if labor market conditions deteriorate

6.3 Player Positioning Matrix

Best positioned within the sector (in order of strategic advantage):

1. Banco de Chile (BCH): Best-in-class profitability (21.9% ROE), superior asset quality (2.4% NPL), industry-leading efficiency (37.4% C/I ratio). Dividend yield attractive with 84.7% payout of 2025 earnings (CLP 9.998/share).
2. Banco Santander Chile (BSAC): Largest market share in key segments, strongest fee income franchise (credit cards, current accounts), ROE leadership (23.5%). Higher NPLs and mortgage exposure are near-term risks.
3. BCI: Solid mid-market and corporate franchise, growing digital capabilities. Less liquid ADR may limit foreign investor participation.

6.4 Coverage Universe Selection

For the purposes of this coverage initiation, we focus on Banco de Chile (BCH) as our primary coverage name, based on its combination of superior asset quality, best-in-class efficiency, strong profitability, and attractive shareholder returns. BCH also offers the most liquid ADR for international investors seeking Chilean banking exposure.
