Best execution is one of the most commonly used terms across financial markets. Many believe that it just refers to pricing, but as recent events in the banking industry demonstrate, there are other important considerations that you shouldn’t take for granted.
When assessing the overall FX execution quality and execution governance in the context of best execution, it is important to consider a wide range of execution factors to determine the optimal execution arrangements that can help a firm achieve a best execution on a continuous basis.
It is widely known that execution prices and costs are probably the most important execution factors in a normal market environment.
We believe firms should seek to achieve competitive execution prices and transparent cost structure. They can do this by adopting a multi-bank FX execution platform where multiple liquidity providers are competing to provide exchanges rates. This enables them to transparently compare and execute FX rates from multiple providers. The execution prices and costs can be accessed and monitored via an independent Transaction Cost Analysis (TCA) to demonstrate best execution.
However, as the recent events with Silicon Valley Bank and Credit Suisse illustrate, other execution factors beyond pricing and costs can play a significant role.
For instance, the likelihood of settlement typically becomes the crucial execution factor when counterparty risk dominates the market. As a result, selecting and performing appropriate due diligence on counterparties become an integral part of the best execution.
Firms should consider establishing a robust counterparty risk evaluation framework that considers of a range of risk factors, including:
In addition to reviewing and assessing the counterparty risks, the recent banking crisis events also highlight the importance of establishing a robust FX execution contingency plan that takes into account of legal and operational complexities.
If the counterparty becomes unavailable, the firm should be able to quickly and efficiently manage the existing FX trades by way of:
Once existing trades have been managed, firms can then implement new FX trades as required by the business.
