Who Are the Participants of Market Structure?

The participants of Forex market structure are the following:

Commercial Banks

These banks contribute to market liquidity, facilitate capital formation, and play a crucial role in intermediating funds between savers and borrowers.

Transnational Corporations

Transnational corporations operating in South Africa, including multinational companies and foreign investors, significantly influence the country's market structure.

Retail Traders

Institutional Traders

Institutional traders wield substantial influence over market structure due to their significant capital allocation and trading activities.

What Types of Market Structures Exist?


There are various types of market structures, each characterised by unique features and degrees of competition:

Perfect Competition

Perfect competition represents a theoretical market structure where numerous small firms compete with homogeneous products, and entry and exit barriers are low. In South Africa, perfect competition may be observed in specific segments of the agricultural sector, where many small-scale farmers produce identical goods such as grains or vegetables.

Monopolistic Competition

Monopolistic competition characterises markets with many firms producing differentiated products, allowing firms to exert some degree of market power through branding and product differentiation. Sectors such as retail, restaurants, and consumer goods often exhibit monopolistic competition, with firms competing based on product differentiation and marketing strategies.


An oligopoly occurs when a few large firms dominate a market, leading to intense competition and potential collusion among competitors. Industries such as telecommunications, banking, and mining are examples of oligopolistic markets, where a few major players wield significant market power and influence pricing and market dynamics.


A monopoly exists when a single firm controls the entire market, with no close substitutes available. While pure monopolies are rare, South Africa has seen monopoly power in sectors such as electricity distribution, where state-owned enterprises or private companies hold exclusive rights to provide essential services in specific regions.

What Factors Influence Market Structure?

  • Technological Innovation: Technological advancements influence market structure by enabling new business models, disrupting traditional industries, and altering consumer preferences. Adopting digital technologies, e-commerce platforms, and fintech innovations has transformed market dynamics in sectors such as finance, retail, telecommunications, and so on.
  • Market Demand and Consumer Behaviour: Market demand and consumer preferences influence market structure by shaping industry concentration, product differentiation strategies, and pricing dynamics.

  • Economic Conditions: Macroeconomic factors, including GDP growth, inflation rates, interest rates, and exchange rate fluctuations, affect market structure by influencing industry profitability, investment decisions, and market entry barriers. Economic downturns or recessions may lead to industry consolidation, restructuring, or market exit.
  • Industry Dynamics and Competitive Forces: Industry-specific factors such as economies of scale, production costs, technological barriers, and competitive rivalry shape market structure by determining the number and size of firms operating within an industry. In South Africa, competitive forces drive market consolidation in the banking, telecommunications, and mining sectors.
  • Globalisation and Trade Policies: Globalisation and trade agreements impact market structure by opening markets to foreign competition, promoting export-oriented industries, and facilitating cross-border investments. Trade liberalisation efforts influence market access, competition levels, and industry specialisation.

How does the Central Bank Shape Market Structure?

The South African Reserve Bank plays a pivotal role in shaping market structure through various monetary policy tools and regulatory measures:

  • Monetary Policy Decisions: The SARB's Monetary Policy Committee (MPC) determines key interest rates, such as the repo rate, to achieve its primary price stability mandate.

Exchange-rate interventions influence currency valuations, trade flows, and investor perceptions of economic stability, shaping market structure.

Tips for Using Market Structure

Here are some tips for using market structure to your advantage:

Utilise Several Time Frames

Analysing market structure across multiple time frames provides a comprehensive view of price movements and trends. Traders should consider using daily, hourly, and shorter-term charts to identify key support and resistance levels, trend directions, and potential entry and exit points.

Analyse Various Assets

Diversifying across different asset classes allows traders to capitalise on diverse market opportunities and mitigate risks. By analysing market structure across various assets, traders can identify correlations, market inefficiencies, and trading signals.

Utilise Technical Indicators

Technical indicators, such as moving averages, relative strength index (RSI), and Fibonacci retracements, complement market structure analysis by providing additional insights into price momentum, overbought or oversold conditions, and trend reversals. Traders should integrate technical indicators into their analysis to validate market structure signals and enhance trading decisions.

Keep Watch for Role Reversals

Identifying role reversals, where previous support levels become resistance and vice versa, is crucial for understanding market structure shifts. Traders should monitor price action around key levels and observe how market participants react to identify potential role reversals and adjust their trading strategies accordingly.

Be Mindful of Context

Considering broader economic, geopolitical, and market factors provides context for interpreting market structure signals. Traders should stay informed about relevant news, events, and developments that may impact market sentiment, volatility, and trends, allowing them to make informed decisions within the context of market structure analysis.

What About Support and Resistance Levels in Market Structure?


Support and resistance levels play important roles in determining market structure and guiding trading decisions:

  • Support: Support levels represent price levels where buying interest outweighs selling pressure, preventing prices from falling further. Support levels may be identified based on historical price data, chart patterns, or key technical indicators. Traders often use support levels to establish long positions or initiate buy orders, anticipating price reversals or bounces upwards.
  • Resistance: Resistance levels, on the other hand, denote price levels where selling pressure exceeds buying interest, hindering further price advancement. Traders identify resistance levels through technical analysis techniques such as trendlines, moving averages, or Fibonacci retracements. Resistance levels act as barriers to price movement, prompting traders to consider selling positions or implementing short-selling strategies to capitalise on potential price reversals or corrections.

Effectively recognising and interpreting support and resistance levels enables traders to make informed trading decisions, manage risk, and identify potential entry and exit points within the market structure.

Bottom Line and Key Takeaways

Understanding market structure is essential for traders. By analysing market participants, types of market structure, and factors influencing it, traders can develop effective trading strategies, manage risks, and capitalise on opportunities presented by market dynamics.

The SARB's monetary policy decisions, exchange-rate interventions, reserve management practices, and regulatory oversight play a crucial role in shaping market structure and maintaining the stability and efficiency of financial markets.
