Banking Law and Investment Services Regulation — Spain

1. Introduction

Investment services regulation in Spain governs the activities of financial institutions that provide investment-related products and services to clients. It forms an important part of Spanish banking and financial law because many banks operate not only as deposit-taking institutions but also as providers of investment products.

Investment services include:

investment advice;

portfolio management;

execution of client orders;

dealing in financial instruments;

underwriting;

placement of securities;

investment research;

trading services.

The Spanish framework is strongly influenced by:

Spanish Securities Market Law;

European Union financial regulation;

Markets in Financial Instruments rules (MiFID framework);

investor protection standards;

anti-money laundering rules;

corporate governance requirements;

supervisory activities of the National Securities Market Commission (CNMV).

2. Regulatory Authorities in Spain

The Comisión Nacional del Mercado de Valores (CNMV) is Spain's principal securities-market supervisor.

Its responsibilities include:

supervising investment firms;

monitoring financial markets;

protecting investors;

supervising disclosure obligations;

enforcing securities regulations.

2.2 Banco de España

Banco de España supervises credit institutions.

Where banks provide investment services, cooperation between Banco de España and CNMV becomes important because banks may simultaneously operate as:

lenders;

financial instruments;

investment firms;

market conduct;

8. Market Abuse Regulation
