Regulation & Central Banks · Five Value-Chain Layers · Foundation Pillars · Six-Jurisdiction Lens
Not a sector — the cross-cutting field that sets the rules, the money and the rails for every layer below. Central banks set policy rates, act as lender of last resort and run the RTGS systems; global standard setters (BCBS, FSB, IOSCO, CPMI, FATF) write the playbook that national authorities adopt — from the Fed, ECB and Bank of England to the PBoC, HKMA and CBUAE.
Banks lend and underwrite; equity and debt capital markets, syndicated loans, private credit and securitization turn savings into funding for firms and governments.
Exchanges, ATSs/MTFs, dealers and RFQ platforms match buyers and sellers. Best-execution rules, repo funding and benchmarks (SOFR, LPR, HIBOR, EIBOR) set the terms.
CCPs novate and net trades, CSDs settle delivery-versus-payment, custodians safekeep and service assets. Cycles differ: T+1 in the US, T+0/T+1 for A-shares, T+2 in Hong Kong and the UAE.
RTGS for large values, batch rails for bulk, 24/7 instant payments, card schemes and cross-border correspondent banking — now largely on ISO 20022 messaging.
Mutual funds, ETFs, UCITS, hedge and private-equity funds, pensions and sovereign wealth funds (ADIA, Mubadala, CIC) allocate long-term capital across every market above.
Market, credit, liquidity, operational and model risk. VaR and Expected Shortfall, stress tests, Basel capital (CET1 ≥ 4.5% of RWA) and liquidity ratios (LCR, NSFR ≥ 100%).
Identifiers (ISIN, LEI, FIGI, USCC), messages (FIX, FpML, ISO 20022) and systems (OMS/EMS, core banking, ledgers). Money is decimal, idempotent and reconciled.
US GAAP vs IFRS, with CAS and HKFRS converged to IFRS. Fair-value Levels 1–3, CECL vs IFRS 9 expected losses, regulatory and trade reporting, AAOIFI for Islamic banks.
Neobanks, super-app payments, open finance, stablecoin regimes (GENIUS Act, MiCA, Hong Kong, CBUAE), CBDCs (e-CNY, Digital Dirham, mBridge) and tokenized funds.

Households, pension funds, insurers and sovereign wealth funds supply capital as deposits, premiums and investments, and bear risk in return for interest, dividends and coupons.
Funds and insurers pool savings and invest them through markets. Banks transform short-term deposits into long-term loans and usually lend straight to borrowers, skipping markets; most credit in Mainland China and the euro area flows that way.
Primary markets raise new capital (IPOs, bonds, sukuk). Secondary markets — NYSE, HKEX, SSE, ADX, DFM — provide liquidity and price discovery but no new cash for the issuer. Savers can also buy securities directly, without an intermediary.
Firms, households and governments put the capital to work and pay it back as interest, coupons and dividends — the returns that flow back to savers.
Central banks set the policy rate, act as lender of last resort and run RTGS systems (Fedwire, T2, CHAPS, CNAPS, CHATS, UAEFTS); regulators license and supervise every node. Underneath, payments, clearing, settlement and custody move the cash and securities legs — where stress usually shows first.
Stock Connect (2014/2016), Bond Connect (2017/2021), Swap Connect (2023) and Wealth Management Connect (2021) open each market through Hong Kong while Mainland capital controls stay in place.
SWIFT messaging over correspondent banks (ISO 20022 after the Nov 2025 MT cut-over); CIPS for RMB; the mBridge multi-CBDC platform (PBoC, HKMA, CBUAE, BoT; Macao since 2026); Payment Connect (since Jun 2025) linking Hong Kong FPS with Mainland IBPS.
DIFC (2004) and ADGM (2015) run their own common-law-based legal systems, courts and regulators (DFSA, FSRA) beside federal law, the CBUAE and SCA. Same country, different rulebooks — always name the regime.
EU, UK and Switzerland move to T+1 on 11 Oct 2027; Hong Kong targets Q4 2027 (HKEX consulted in 2026); tokenized collateral and atomic-settlement pilots.
Basel III final reforms: EU CRR3 live since Jan 2025; UK Basel 3.1 from 1 Jan 2027; US re-proposed in Mar 2026 with net capital relief; FRTB timing still differs by region.
GENIUS Act (US, effective by 18 Jan 2027), MiCA (EU), Hong Kong's Stablecoins Ordinance (first licences Apr 2026) and CBUAE payment-token rules set who may issue and where tokens may be used to pay.
e-CNY became an interest-bearing deposit in Jan 2026; mBridge, the Digital Dirham rollout, wholesale e-HKD and the digital euro (pilot planned for 2027); tokenized money-market funds and Treasuries used as collateral.
Resolving property-developer and LGFV debt, monetary easing, and further opening of onshore markets to foreign investors.
Model-risk guidance (SR 26-2, which replaced SR 11-7 in Apr 2026; PRA SS1/23), EU AI Act high-risk credit scoring (deferred to Dec 2027), China's generative-AI measures, and explainability for credit decisions.
