I have just published a new article on FinoLib, my free finance education library: ESG and Sustainable Finance Explained. It is part of Volume I: Global Economy. Below is a summary of the topic in plain, expert language, so you can follow the idea even before you open the full article.
8.7 ESG and Sustainable Finance
The idea in plain words
ESG scores companies on environmental, social and governance factors, and sustainable finance turns them into products such as green and sustainability-linked bonds. EU rules force disclosure and define what counts as sustainable.
Key points
■Cumulative issuance of green, social, sustainability and sustainability-linked bonds reached $8.1 trillion by the end of 2025, according to the Climate Bonds Initiative.
■In a sustainability-linked bond the coupon is tied to the issuer hitting specific ESG targets, so it rises if the company misses a stated emissions target by a stated date.
■Under the EU’s SFDR, Article 8 funds promote environmental or social characteristics and Article 9 funds have sustainable investment as their objective; the Commission proposed a revision on November 20, 2025, so check the current text.
A closer look
ESG stands for Environmental, Social, and Governance — a framework that investors increasingly use to evaluate companies on non-financial factors alongside traditional financial performance. What began as a consideration in ethical investment portfolios two decades ago has become mainstream in global capital markets, driven by institutional investor demand, growing investor interest in how ESG factors may affect long-term risk, although the evidence on returns is mixed, and the weight of mandatory regulatory disclosure requirements in major markets.
Career Insight
ESG literacy is no longer a specialization — it is a baseline expectation in most major financial institutions globally. Whether you work in equity research (ESG factors are now standard in most analytical frameworks), operations (ESG data validation and regulatory reporting are growing compliance requirements), risk management (physical and transition climate risks are now incorporated into stress testing), or client services (institutional clients increasingly ask about the ESG characteristics of the products they hold), you will encounter ESG as a…
Recap
ESG scores companies on environmental, social and governance factors, and sustainable finance turns them into products such as green and sustainability-linked bonds ($8.1 trillion of cumulative issuance by end-2025, per the Climate Bonds Initiative). EU rules (SFDR and the EU Taxonomy) force disclosure and define what counts as sustainable.
8.8 The Full Chain — From the Global Economy to Your Daily Work
The idea in plain words
One thread runs from a rate decision to a reconciliation break: administered rates move, repo funding costs reprice overnight, collateral loses value as yields rise, margin calls follow, settlements fail and breaks land in the exception queue.
Key points
■On September 16, 2026, the FOMC raised the federal funds target range by 0.25 point to 3.75%–4.00%, moving interest on reserve balances to 3.90% and the overnight reverse repo rate to 3.75%.
■The effective federal funds rate went from 3.63% on September 16 to 3.88% on September 17, and SOFR from 3.62% to 3.85%.
■The 10-year Treasury yield rose from 5.01% on September 16 to 5.29% on September 30.
A closer look
Every concept in Parts 0 to 8 is part of a single, continuous, interconnected system. Nothing stands alone. The chain below traces the journey from the largest possible scale down to the daily work of the professionals who keep it all running; the prose after it then follows one thread of that chain, from a single rate decision to a single reconciliation break.
From a rate decision to a reconciliation break. The chart compresses the whole book into ten steps. Here is one thread of it at full resolution, using the real rate moves of September 2026.
A worked example
Trace the Chain — Part 8 Thought Experiments
1. A trade breaks: the custodian’s records show 10,000 shares, the fund’s internal books show 11,000. Walk the investigation in order — trade, position, cash — and explain why that sequence saves time. 2. The Fed cuts rates 0.5%. Trace the effect to a Bengaluru mortgage-processing team’s workload within 90 days. 3. Your operations team’s error rate is stable, but aged breaks are rising. Which is the leading indicator, what is it warning about, and what would you check first?

India finished moving its equity market to T+1 on January 27, 2023, sixteen months before the US, and on March 28, 2024, added an optional same-day (T+0) cycle for 25 stocks, which SEBI widened in December 2024 to the top 500 companies by market capitalization. The clearing houses split by market.
Recap
One thread runs from a rate decision to a reconciliation break: administered rates move, repo funding costs reprice overnight, collateral loses value as yields rise, margin calls follow, settlements fail, and breaks land in the exception queue.
