The Fix Order and the Pre-Hedge
You are an FX dealer at a bank in London. At 15:35 a real-money client instructs your sales desk to buy €250 million against USD at the 16:00 WM/Reuters fix, "fix or better", with discretion over execution. The order is large relative to the 15:35–16:00 window, which typically trades about €900 million. At 15:50 EUR/USD is 1.0850/1.0852 and the sales trader tells you he expects month-end index rebalancing to generate further EUR demand before the fix. You consider buying €80 million in the market now to hedge the order, and a hedge fund client calls the sales desk asking "where do you think the fix will print?" Your bank has signed the FX Global Code and discloses that it may pre-hedge client orders.
1. Assess whether buying €80 million at 15:50 would be acceptable pre-hedging, and set out the conditions under which any pre-hedge could be justified.

Pre-hedging is not prohibited by the FX Global Code, but it is constrained. The bank may trade ahead of a client order only where it manages risk arising from that order, the activity is in the client's interest, it is proportionate to the risk, and it is disclosed. Each of those conditions is doubtful here.
Proportionality: €80m is 32% of the order and about 9% of the expected window volume, executed in the 10 minutes before the fix at a point when month-end demand is expected. That is large enough to move the market and the fix itself. Because the client's benchmark is the fix, pushing the fix up directly worsens the client's execution; a hedge that moves the benchmark against the client is difficult to describe as being in the client's interest.
Conditions for a defensible hedge: hedge only the residual risk that cannot be worked passively; keep the size small relative to expected volume; avoid concentrating the hedge in the minutes before the fix; document the rationale and the client instruction; and apply independent oversight. Here the better course is to work the order passively, use internal liquidity and any offsetting client flow, and hedge only near the fix if the residual risk is genuinely unmanageable. The "fix or better" instruction does not authorise the bank to take a directional view.
2. How should the sales desk respond to the hedge fund's question about the fix?
Read the worked answer
The hedge fund must not be told about the client order, its size or direction, or the desk's expectation of month-end demand derived from it. Even an oblique answer such as "we see decent euro buying into the fix" would leak confidential client information and could amount to tipping or market abuse. The correct response is a generic market view that could be given to any client, with no reference to the order or to the desk's own position.
The call should be logged with time, content and the name of the salesperson, and Compliance should review whether any information was disclosed. If the salesperson has a close relationship with the hedge fund, the desk head should consider separating the hedge fund coverage from the client-order flow. The bank should also check whether the hedge fund traded ahead of the fix after the call; that would turn an awkward question into a potential investigation.
3. Set out the execution plan you would follow for the €250m order and the measures you would use to demonstrate best execution.
Read the worked answer
The plan should combine passive and active execution and avoid a single large print in the fix window. Work part of the order earlier in the window with limit orders at or below the prevailing offer, and keep the remainder for the fix period; use any internal or offsetting flow first. Set a maximum deviation from the arrival mid (say 15 pips) and escalate to the desk head if it is breached rather than chasing the market. Keep the client informed of progress if the order is at risk.
To demonstrate best execution, record the arrival price, the fix, the achieved average rate, the venue or method for each fill, and the split between passive and aggressive execution. Transaction cost analysis should compare the outcome with the fix and with the arrival mid, and should explain any deviation. The record should also show why any hedging was done and how its size was determined. Finally, the bank should review the order against its pre-hedging disclosure and its conflicts policy, because the client's benchmark and the bank's hedging activity create a structural conflict that must be managed and evidenced, not merely disclosed.
