## Concept

The architecture of a [Request for Quote](https://prime.greeks.live/area/request-for-quote/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) (RFQ) system is a direct reflection of a firm’s philosophy on liquidity interaction. When you initiate a bilateral price discovery request, the system’s design dictates the flow of information and the competitive dynamics between [liquidity providers](https://prime.greeks.live/area/liquidity-providers/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite). The fundamental divergence between a tiered and a flat access model lies in the treatment of those potential counterparties. One model champions egalitarian access for a given request, while the other systematically segments and privileges participants to shape liquidity behavior over time.

A flat [access model](https://prime.greeks.live/question/what-are-the-core-differences-between-sponsored-access-and-direct-market-access/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) operates as a pure, simultaneous auction. When an institution seeks a price for a block of securities, its request is broadcast to a pre-selected group of dealers at the same instant. Each dealer possesses an identical window of opportunity and information parity.

The defining characteristic of this structure is its transactional meritocracy; the best price submitted within the response window wins the trade. This approach is engineered to maximize immediate competition for each individual request, creating a level playing field that encourages aggressive pricing from all participants who are invited to the auction.

## What Is the Core Principle of a Tiered System?

A tiered access model introduces a layer of segmentation and differentiation into the [price discovery](https://prime.greeks.live/area/price-discovery/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) protocol. This structure moves beyond the single-transaction focus of a flat model to actively manage and incentivize relationships with liquidity providers. The tiering mechanism can manifest in two primary domains ▴ on the side of the [liquidity provider](https://prime.greeks.live/area/liquidity-provider/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) or on the side of the trading platform and its client.

When executed by the liquidity provider, tiering becomes a risk management tool. Dealers analyze the trading behavior of their clients, classifying them based on metrics that reveal their potential toxicity. A client who consistently profits from fleeting mispricings imposes a cost on the dealer, a phenomenon often termed “[adverse selection](https://prime.greeks.live/area/adverse-selection/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite).” In response, the dealer creates internal tiers, offering its best prices to clients whose order flow is considered benign or uninformed, while systematically widening spreads for clients identified as toxic. This is a defensive mechanism designed to protect the dealer’s profitability.

Conversely, when the platform or the institutional client implements tiering, it functions as an incentive structure. Liquidity providers are categorized based on their performance. Those who consistently provide tight spreads, rapid response times, and high fill rates are elevated to a premier tier.

This status may grant them privileges such as a “last look” capability, where they get a final opportunity to improve their quote, or a “first look,” where they see requests before lower-tiered providers. This model actively rewards quality liquidity provision, seeking to build a more reliable and robust pool of capital for the long term.

> A flat RFQ model prioritizes maximum competition on a per-trade basis, whereas a tiered model cultivates preferred liquidity relationships through systematic incentives and risk segmentation.

The choice between these two architectures reveals an institution’s core objective. A flat system is designed to achieve the best possible price at a specific moment in time by fostering broad, immediate competition. A tiered system is designed to secure the most reliable liquidity over the long run by building a sustainable ecosystem where high-quality participation is explicitly rewarded.

## Strategy

The strategic decision to implement either a tiered or a flat [RFQ access model](https://prime.greeks.live/area/rfq-access-model/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is a foundational choice in designing an institution’s execution policy. This choice extends beyond mere technological preference; it codifies the firm’s approach to market interaction, counterparty relationships, and risk management. The two models represent distinct philosophies for sourcing off-book liquidity, each with a unique set of objectives and consequences for execution quality.

## The Strategy of Unfettered Competition

A flat [RFQ model](https://prime.greeks.live/area/rfq-model/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) is predicated on the strategic principle of maximizing competitive pressure at the point of execution. By broadcasting a request to all selected dealers simultaneously, the initiator creates a self-contained, high-stakes auction for that specific order. The primary goal is to compress dealer spreads to their absolute minimum for that moment in time.

This approach is particularly effective in liquid markets where numerous dealers are willing and able to price an instrument competitively. The strategy assumes that a wider net, without prejudice, will capture the best price available from the pool of potential counterparties.

This model’s strength lies in its simplicity and its demonstrable fairness on a trade-by-trade basis. It provides a clear audit trail for [best execution](https://prime.greeks.live/area/best-execution/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite), as the institution can prove it solicited quotes from a diverse panel of liquidity providers and selected the winning bid from a level playing field. The strategic trade-off, however, is a potential lack of investment from dealers. If dealers perceive that they are part of a vast, undifferentiated pool and must compete on price alone, they may be less inclined to commit capital during volatile periods or to quote aggressively on more complex, less liquid instruments.

> The flat model’s strategy is to engineer maximum immediate price competition, while the tiered model’s strategy is to cultivate long-term liquidity quality through structured incentives.

## The Strategy of Cultivated Liquidity

A tiered RFQ model adopts a more strategic, long-term view of liquidity sourcing. Its central thesis is that not all liquidity is of equal quality. The model seeks to identify and reward high-performance liquidity providers to ensure their consistent participation, especially for large or difficult trades.

By creating a system of privileges for top-tier dealers, the platform or institution provides a powerful incentive for these firms to invest in the relationship. This investment manifests as tighter average spreads, faster response times, and a greater willingness to absorb risk.

This approach is a form of relationship management at scale, automated through the trading system’s architecture. The strategic benefit is the creation of a reliable pool of capital that can be accessed with confidence, reducing the uncertainty of execution. The potential downside is a reduction in the sheer breadth of competition for any single trade.

By design, the model funnels more order flow to a select group of providers, which could lead to [information leakage](https://prime.greeks.live/area/information-leakage/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) if not managed properly. The strategy rests on the conviction that the value of reliable, high-quality liquidity from a core group of partners outweighs the potential for a slightly better price from a peripheral provider on any given trade.

The following table provides a comparative analysis of the strategic underpinnings of each model.

### Strategic Framework Comparison RFQ Models

| Strategic Dimension | Flat Access Model | Tiered Access Model |
| --- | --- | --- |
| Liquidity Philosophy | Views liquidity as a commodity to be sourced at the best price in a competitive auction for each trade. | Views liquidity as a service whose quality and reliability can be cultivated over time through incentives. |
| Primary Objective | To maximize immediate price competition and achieve the best possible execution price on a per-trade basis. | To build a sustainable, high-quality liquidity ecosystem and ensure reliable execution, especially for large or illiquid assets. |
| Counterparty Management | Treats all liquidity providers within a given request as equals. Relationship management occurs outside the protocol. | Integrates counterparty management directly into the protocol through performance-based segmentation. |
| Risk Appetite | Minimizes the risk of missing the best price at a single point in time by maximizing the number of participants. | Minimizes the long-term risk of poor execution during volatile periods by rewarding reliable partners. |
| Information Dynamics | Wider dissemination of trade intent for a given request, potentially increasing information leakage. | More controlled dissemination of trade intent, often directed to a smaller, trusted group of providers first. |

## How Does Tiering Affect Dealer Behavior?

The implementation of a [tiered model](https://prime.greeks.live/question/how-does-a-tiered-data-strategy-impact-machine-learning-model-performance/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) fundamentally alters the incentive structure for market makers. In a flat system, a dealer’s primary motivation is to win the current trade, which often leads to highly aggressive, all-or-nothing pricing. In a tiered system, the dealer’s motivation expands. They are incentivized not only to win the current trade but also to maintain or improve their tier ranking.

This encourages more consistent and constructive behavior. A dealer might provide a competitive quote even when their models suggest they are unlikely to win, simply to maintain a high response rate. They are less likely to show exceptionally wide prices, as this could negatively impact their quality score and jeopardize their privileged status. This strategic cultivation leads to a more predictable and stable pricing environment for the institutional client.

## Execution

The execution mechanics of flat and tiered RFQ models translate their respective strategies into operational reality. The protocols and data analysis underlying each system determine how information flows, how participants interact, and ultimately, how execution quality is measured and optimized. Understanding these operational details is essential for any institution seeking to align its trading architecture with its strategic goals.

## Executing within a Flat Access Architecture

The operational workflow of a flat RFQ model is direct and transparent. The process is initiated when a trader on the buy-side builds an order and selects a list of liquidity providers to include in the competition. The platform then disseminates the RFQ simultaneously to all selected dealers. Key parameters of the execution process include:

- **Simultaneous Dissemination**
The request is sent to all dealers at the exact same time, ensuring no participant has a time advantage.

- **Fixed Response Window**
Dealers are given a predetermined amount of time (e.g. 30 to 120 seconds) to analyze the request and submit a firm, executable quote.

- **Information Parity**
All dealers receive the same information about the instrument, size, and any other relevant parameters. The identity of competing dealers is typically masked.

- **Merit-Based Selection**
At the conclusion of the response window, the initiating trader is presented with all submitted quotes. The system highlights the best bid and offer, and the trader executes based on this simple, meritocratic outcome.

The primary post-trade analysis in this model involves Transaction Cost Analysis (TCA), comparing the execution price against various benchmarks (e.g. arrival price, VWAP) to validate that the competitive process yielded a favorable result for that specific trade.

## Executing within a Tiered Access Architecture

The execution mechanics of a tiered model are more complex, involving continuous data analysis to maintain the tiering structure. The two primary forms of tiering, LP-side client classification and platform-side LP ranking, have distinct operational workflows.

![Central mechanical pivot with a green linear element diagonally traversing, depicting a robust RFQ protocol engine for institutional digital asset derivatives.

## LP-Side Execution Client Toxicity Analysis

From the liquidity provider’s perspective, tiering is a continuous process of client evaluation. The goal is to quantify the “toxicity” of a client’s flow, which is a measure of how much adverse selection the LP suffers when trading with them. A sophisticated LP will use a variety of metrics to build a client score. This score is then used to automatically adjust the spread offered on future RFQs from that client.

The table below illustrates a simplified model of how a dealer might classify its clients. The core metric is “[Hold Time Alpha](https://prime.greeks.live/area/hold-time-alpha/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite),” which measures the profitability of a client’s trades against the market price a short time after the execution. A consistently negative [Hold Time](https://prime.greeks.live/area/hold-time/?utm_source=options.greeks.live&utm_medium=referral&utm_campaign=satellite) Alpha indicates the client is skilled at “sniping” stale quotes just before the market moves, which is a hallmark of toxic flow.

### Liquidity Provider Client Tiering Model

| Client ID | Trade Count (90d) | Avg. 5s Hold Time Alpha (bps) | Response Hit Rate (%) | Client Tier | Spread Adjustment (bps) |
| --- | --- | --- | --- | --- | --- |
| Client A – Pension Fund | 150 | +0.25 | 15% | Tier 1 (Premium) | -0.50 |
| Client B – Asset Manager | 450 | +0.05 | 25% | Tier 2 (Standard) | 0.00 |
| Client C – HFT | 1,200 | -0.85 | 5% | Tier 3 (Toxic) | +1.50 |
| Client D – Hedge Fund | 300 | -0.10 | 10% | Tier 2 (Standard) | 0.00 |

In this execution model, when an RFQ arrives from Client C, the dealer’s pricing engine automatically calculates its standard bid-ask spread and then applies the +1.50 bps penalty. When a request comes from Client A, the engine applies a -0.50 bps discount, resulting in a tighter, more competitive quote.

## Platform-Side Execution LP Performance Ranking

When the trading platform or the buy-side institution implements tiering, the focus shifts to evaluating the performance of the liquidity providers. This creates a system where privileges are earned through consistent, high-quality quoting. The execution workflow can be structured in several ways:

- **Waterfall RFQ**
The request is first sent only to Tier 1 liquidity providers. If no quote meets the client’s required threshold after a short period, the request is then cascaded down to Tier 2 providers, and so on. This protects the trade’s intent from being broadcast too widely.

- **Last Look Privilege**
All tiers see the request simultaneously, but a Tier 1 provider is given a final, brief window (e.g. 500 milliseconds) to match or improve upon the best price submitted by any other provider. This is a powerful incentive to remain in the top tier.

> A tiered execution model transforms the RFQ from a simple auction into a dynamic, data-driven relationship management system.

The platform maintains a scorecard on each LP, updated in real-time. This scorecard determines their rank and associated privileges. The goal is to create a virtuous cycle where dealers are incentivized to provide better quotes to gain privileges, which in turn leads to better execution for the client.

## What Does Your Execution Protocol Say about Your Firm

The choice between these two RFQ access models is ultimately a reflection of your institution’s core operational ethos. A flat model speaks to a belief in the power of pure, unadulterated competition in every instance. It is a system built on transactional integrity and the pursuit of the sharpest possible price at the moment of execution.

A tiered model, conversely, speaks to a belief in the value of cultivated relationships and the strategic management of liquidity as a long-term asset. It views the market as an ecosystem to be shaped, where incentives can foster a more stable and reliable trading environment.

Consider your firm’s most challenging trades. Are they best served by broadcasting your intent as widely as possible, or by engaging a select group of trusted partners who have been incentivized to handle your most sensitive orders? The answer to that question will guide you toward the architecture that best aligns with your definition of superior execution. The knowledge of these systems is a component of a larger framework of intelligence required to build a truly decisive operational edge.

                "text": "A tiered access model introduces a layer of segmentation and differentiation into the price discovery protocol. This structure moves beyond the single-transaction focus of a flat model to actively manage and incentivize relationships with liquidity providers. The tiering mechanism can manifest in two primary domains: on the side of the liquidity provider or on the side of the trading platform and its client."

                "@type": "Answer",
                "text": "The implementation of a tiered model fundamentally alters the incentive structure for market makers. In a flat system, a dealer's primary motivation is to win the current trade, which often leads to highly aggressive, all-or-nothing pricing. In a tiered system, the dealer's motivation expands. They are incentivized not only to win the current trade but also to maintain or improve their tier ranking. This encourages more consistent and constructive behavior. A dealer might provide a competitive quote even when their models suggest they are unlikely to win, simply to maintain a high response rate. They are less likely to show exceptionally wide prices, as this could negatively impact their quality score and jeopardize their privileged status. This strategic cultivation leads to a more predictable and stable pricing environment for the institutional client."
