The Central Bank of Mexico’s Directorate General of Payment Systems and Market Infrastructures has opened its 2026 Internal Summer Researchers Programme for PhD students to undertake supervised research projects on payment systems and financial market infrastructures, with a maximum research period of 60 calendar days during July and August. Eligibility requires applicants to be enrolled in a relevant PhD programme and have completed at least three years of study, with English proficiency (Spanish preferred). Applications must include a research proposal and work plan designed to deliver a final report within two months, alongside a CV, academic status documentation, and an academic recommendation letter. Proposed topics include artificial intelligence techniques, network modelling, discrete choice models, models of operational and liquidity risk and systemic risk propagation through payment systems, industrial organisation and regulatory frameworks for payment systems and market infrastructures, and predictive and correlation models to monitor and prevent degradation or malfunction in critical infrastructure components. Selected participants will contract with the central bank for professional services and may receive up to USD 6,900 before tax, comprising up to USD 1,500 for economy-class round-trip airfare (conditional on at least 53 days in-person), two USD 1,500 instalments tied to midterm and final deliverables, and up to USD 2,000 based on assessed impact and usefulness (USD 1,000 for “medium” and USD 2,000 for “high”), plus up to USD 200 per month for meals. Applications close on 20 April 2026, with selection decisions due by 8 May 2026. The programme is primarily in-person at the Central Bank of Mexico, with the option of up to 10 calendar days of remote work subject to approval, and selected candidates will need to meet additional contracting and tax documentation requirements as part of onboarding.
