The exchange-rate channel returns to the euro-area policy debate

During the tightening cycle, the exchange rate was a secondary story: with policy rates moving in large steps, the interest-rate channel dominated the transmission of monetary conditions and the currency was largely a residual. With the policy rate stable and other major central banks on their own distinct paths, the residual has become the story. Relative monetary conditions have to express themselves somewhere, and if not in the curve then in the currency.

This is a familiar situation rather than a novel one, but it has been long enough that a generation of treasury policies were written without it in mind. Several of the FX frameworks we review were drafted or last revised when the dominant risk was interest-rate volatility, and they show it.

Transaction hedging is the easy part

Most corporate FX policies handle transaction exposure competently: a contracted receivable in a foreign currency is identified, quantified and hedged with a forward, and the accounting follows. Where policies are typically weaker is on translation exposure — the effect of currency moves on the consolidated value of foreign subsidiaries and their earnings.

Translation exposure is genuinely harder, because hedging it perfectly requires taking a cash-flow risk to protect an accounting outcome. Firms reasonably differ on how much of that trade-off they want. But the difficulty is not a reason to leave the exposure unquantified, and unquantified is what we most often find. A board that has decided not to hedge translation risk is in a defensible position; a board that has not measured it is not.

A board that has decided not to hedge translation risk is in a defensible position. A board that has never measured it is not.

Multi-currency funding: watch the basis, not the spot

For groups that fund in one currency and invest in another, the relevant price is not the spot exchange rate but the cross-currency basis. The basis moves with the relative demand for funding in each currency, it widens predictably at quarter and year ends, and it can swamp the apparent advantage of issuing in whichever market looks cheapest on a headline coupon comparison.

The discipline we encourage is simple: compare funding options on a post-swap, all-in basis, in the currency in which the proceeds will actually be used, and refresh the comparison close to execution. A cross-currency arbitrage identified six weeks before pricing has often closed by the time the trade is done.

Look for the natural hedge first

Before any external hedge is transacted, it is worth mapping the group’s gross currency flows rather than its net accounting exposure. Groups with operations across several countries frequently discover that a material share of an apparent exposure is offset elsewhere in the organisation, and that the offset is invisible because each entity manages its own position.

• Map gross flows by currency across all entities before sizing any external hedge.
• Net internally where legal and tax structures permit; an internal netting centre is usually cheaper than the equivalent external hedges.
• Quantify translation exposure even where the decision is not to hedge it.
• Compare funding alternatives post-swap and refresh the comparison near execution.

Our financial markets desk works with clients on exactly this sequence: measure, net internally, then hedge the residual. It is a less exciting process than trading a view on the currency, and it reliably produces a smaller hedging bill.
