The Foreign Exchange Professionals Association has published new industry guidance clarifying how foreign exchange spread grids should be interpreted, arguing that they are designed to provide contextual pricing guidance rather than serve as firm quotes, contractual commitments, or measures of execution quality.
The paper, FXPA Guidance: The Role and Interpretation of FX Spread Grids, was developed by the association’s Buy Side Working Group following discussions with market participants across the institutional foreign exchange ecosystem. It aims to establish a common understanding of how spread grids should be used as electronic trading, transaction cost analysis, and quantitative execution assessment continue to reshape the FX market.
The guidance arrives at a time when institutional clients increasingly rely on empirical execution data rather than indicative pricing schedules to evaluate liquidity providers, making it more important to distinguish between reference pricing tools and executable market prices.
Spread Grids Are Intended As Context, Not Commitments
Spread grids have long been used by banks and liquidity providers to communicate expected trading costs across currency pairs, tenors, notional sizes, and market conditions. However, FXPA says differing interpretations of those grids have sometimes created unrealistic expectations between liquidity providers and buy-side firms.
The guidance makes clear that spread grids should be viewed as indicative reference tools that describe expected execution costs under representative market conditions. They are not executable quotes, service-level agreements, contractual pricing commitments, or substitutes for price discovery through live trading. Actual execution outcomes will always depend on prevailing liquidity, volatility, timing, trade size, counterparty-specific considerations, and broader market conditions. Richard Turner, Senior Trader at Insight Investment and Chair of FXPA’s Buy Side Working Group, said market participants need a clearer understanding of both the strengths and limitations of spread grids.
“Spread grids have been a longstanding feature of the FX market, providing valuable context around expected trading costs and liquidity conditions. However, as execution workflows become increasingly data-driven and sophisticated, it is important that market participants understand both what spread grids can tell us – and what they cannot. This guidance is intended to promote a common understanding of their role as reference tools, helping support more informed execution decisions, more constructive dialogue between counterparties, and stronger execution-quality assessment across the market.”
Execution Quality Should Be Measured Using Trading Data
A central theme of the paper is that modern execution analysis should rely on observed market data rather than static pricing references. FXPA argues that spread grids should complement, not replace, transaction cost analysis, request-for-quote histories, streaming market data, and historical execution results when firms evaluate trading performance. The guidance notes that spreads are inherently dynamic and influenced by factors including currency pair, tenor, notional size, market volatility, liquidity conditions, economic announcements, time of day, and counterparty credit considerations. As a result, an indicative spread grid represents only a snapshot of expected market conditions rather than a guarantee of future execution. Among the paper’s key recommendations is that firms avoid using spread grids to challenge individual executions without considering the prevailing market environment. Instead, execution quality should be assessed over time using observed trading outcomes across comparable transactions.
Guidance Addresses Common Misconceptions
The document outlines what spread grids are intended to achieve from both liquidity provider and buy-side perspectives while also identifying several common misconceptions surrounding their use.
According to FXPA, spread grids can help market participants estimate expected trading costs, support transaction cost modelling, inform execution strategies, and provide context when reviewing pricing behavior over time. They may also assist buy-side firms when calibrating quantitative trading models or reviewing relationships with liquidity providers.
At the same time, the association stresses that spread grids should not be treated as fixed pricing commitments, cross-bank comparison tools, substitutes for request-for-quote processes, or standalone measures of liquidity provider performance. Because each institution prices risk differently according to its own inventory, infrastructure, and market positioning, individual spread grids should not be interpreted as directly comparable benchmarks.
The paper includes an illustrative spread grid demonstrating how expected spreads can vary according to currency pair, tenor, trade size, liquidity conditions, and market volatility, while emphasizing that the example contains hypothetical data and should not be used for commercial purposes or execution decisions. :contentReference[oaicite:8]{index=8}
Industry Seeks Greater Buy Side And Sell Side Alignment
FXPA believes a common interpretation of spread grids can reduce friction between liquidity providers and institutional clients during pricing discussions while improving execution governance across the FX market.
The association argues that better alignment around the purpose and limitations of spread grids will support more constructive dialogue, more consistent execution expectations, and stronger evaluation frameworks as electronic trading continues to evolve. Rather than replacing traditional pricing tools, the guidance positions spread grids as one component of a broader execution framework built around measurable trading outcomes and data-driven analysis.
As institutional FX trading becomes increasingly automated and quantitative, the publication reflects a wider industry trend toward evaluating liquidity providers through historical performance metrics instead of static pricing schedules. Transaction cost analysis, execution benchmarking, and empirical trading data have become central to best execution frameworks across global currency markets, with indicative spread grids serving primarily as planning and communication tools.
Takeaway
FXPA’s new guidance seeks to eliminate longstanding misunderstandings over FX spread grids by emphasizing that they are indicative reference tools rather than pricing commitments or measures of execution quality. As institutional foreign exchange trading becomes increasingly data driven, the association argues that firms should rely on transaction cost analysis, historical execution data, and observed market outcomes to evaluate liquidity providers, using spread grids only as one component of a broader execution framework.
