# Managing FX and Interest-Rate Risk
In October 2015, Google's parent restructured into Alphabet—but a quieter number told a sharper story that quarter: the company disclosed that currency movements had shaved roughly $1.8 billion off revenue over the prior year, even as the underlying business grew. Management had hedged some of it, recovering a few hundred million through its forward program. The rest, they simply absorbed. That single disclosure captures the entire discipline of this lesson: a world-class finance function does not try to hedge everything. It decides, deliberately and defensibly, what exposure to neutralize and what to carry.
The amateur question is "How do we hedge FX?" The CFO's question is "Which exposures are worth the cost and complexity of hedging, and which are we better off accepting, pricing, or operationally restructuring away?" Getting that judgment wrong in either direction is expensive. Over-hedging burns premium, ties up credit lines, and creates accounting noise that IR then has to explain. Under-hedging leaves earnings hostage to markets you don't control.
You already know the taxonomy: transaction, translation, and economic exposure. What matters at this level is that they behave differently, hit different financial statements, and demand different responses. Treating them as one blob is the most common failure in corporate treasury.
Transaction exposure is contractual and dated. You've sold €50M of product with payment due in 90 days; your functional currency is USD. The euro can move 8% before you're paid. This exposure is *knowable, bounded, and cash-settling*—which is precisely why it is the most hedgeable of the three and where most programs should start. The gain or loss is real cash, and it hits earnings.
Translation exposure is an accounting artifact. When you consolidate a Brazilian subsidiary, its real-denominated equity and earnings get restated into USD at period-end rates. The swing flows through *Other Comprehensive Income* (the cumulative translation adjustment), not through net income—unless you sell the subsidiary. Here is the trap: CFOs spend real money hedging translation exposure to smooth a balance-sheet line that has no cash consequence and that sophisticated investors already look through. Occasionally it's justified—if debt covenants are struck on reported equity, or if a leverage ratio could breach. But hedging OCI volatility to make the balance sheet look calmer is usually a solution in search of a problem.
Economic exposure is the one that keeps strategic CFOs awake. It's the effect of sustained currency shifts on your *competitive position and future cash flows*—flows you haven't yet contracted. When the yen weakened structurally, Japanese exporters didn't just book translation gains; their pricing power against U.S. and European rivals shifted for years. A U.S. manufacturer selling into Europe with a domestic cost base has economic exposure even if it invoices in dollars, because a strong dollar makes it uncompetitive versus local players. You cannot fully hedge this with financial instruments—the exposure is diffuse, long-dated, and partly behavioral. You manage it operationally.
The discipline: map each exposure to the right instrument, and refuse to use financial hedges on problems that are actually operational or accounting in nature.
The single most value-destroying mistake in FX management is hedging gross flows instead of net exposure. If your German subsidiary receives €100M and pays €70M in euros, your true exposure is €30M. Hedging €100M means paying transaction costs on €70M of risk that naturally offsets itself. Multiply this across a multinational with dozens of intercompany flows, and the waste compounds.
This is why serious treasury functions build an exposure netting matrix—a consolidated, currency-by-currency, tenor-by-tenor view of all receivables, payables, and forecasted flows across the group. Natural offsets are the cheapest hedge you will ever find: they cost nothing and carry no counterparty risk. The CFO's first move is not to call a bank; it's to demand a clean net-exposure mapmapUsing software to automate repetitive marketing tasks and campaigns, enabling personalisation at scale across channels like email, web, and social.Voir la définition complète →. Most companies discover they've been hedging phantom risk.
Once you have net exposure, quantify the *stakes*, not just the size. Two tools:
Cash-Flow-at-Risk (CFaR): the maximum expected shortfall in operating cash flow, at a given confidence level, over a defined horizon, driven by rate moves. If a 95% CFaR says currency swings could cost you $120M over the year and your covenant headroom is $80M, you have a problem that demands hedging regardless of philosophy. If CFaR is $40M against $600M of EBITDAEBITDAEBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) measures a company's operating profitability before financing and accounting decisions, used to compare core performance across firms.Voir la définition complète →, you may rationally accept it.
Earnings sensitivity ("the cents-per-share test"): translate exposure into EPS impact per 10% currency move. This is the language of your board and your equity analysts. When the CFO can say "a 10% appreciation in the trade-weighted dollar costs us 14 cents of EPS, of which we've hedged 9," the hedging conversation becomes a governance decision, not a treasury hobby.
The output of quantification is a materiality threshold. You do not hedge exposures below it. A rigorous program explicitly accepts small, diversified, or self-offsetting exposures—and documents *why*—so that the hedge book stays focused on risks that actually move the enterprise.
Here is the framework to run on Monday morning. Score each material exposure on four dimensions:
1. Certainty of the underlying flow. A signed contract with a due date is highly hedgeable—use a forward and lock it. A forecasted flow that's 70% likely warrants a *layered* approach: hedge a high percentage of near-dated, high-confidence flows and a declining percentage of more distant, less certain ones. This is the "hedge ratio ladder"—you might cover 90% of Q1 exposure, 60% of Q2, 30% of Q3. It prevents the disaster of hedging revenue that never materializes, which turns a hedge into a naked speculative position.
2. Cash vs. accounting impact. Cash-settling transaction exposure earns priority. Translation exposure earns skepticism—hedge it only when it threatens covenants or a specific stakeholder metric.
3. Cost of the hedge vs. the risk reduced. Forwards are nearly free at inception but obligate you symmetrically—you give up upside. Options cost premium but preserve upside and cap downside; they suit exposures where the flow is uncertain or where you have a directional view you're unwilling to bet the company on. The CFO's judgment: pay for optionality only when the asymmetry is worth it. Over a full cycle, systematically buying options is expensive insurance; systematically selling upside via forwards leaves money on the table in favorable moves. Most mature programs run forwards as the workhorse and use options selectively.
4. Whether the risk is a source of competitive advantage or pure noise. If currency exposure is incidental to your business—you happen to source in one currency and sell in another—hedge the noise so management focuses on operations. If exposure *is* your business or reflects a strategic bet, be honest that you're managing, not eliminating, it.
Now overlay interest-rate risk, which follows the same logic but with a different clock. Your exposure is the mismatch between the rate structure of your assets/cash flows and your liabilities. A company with mostly floating-rate debt in a rising-rate environment has direct earnings exposure; every hike lifts interest expense and compresses coverage ratios. The core instrument is the interest-rate swap—converting floating to fixed (locking cost, giving up benefit if rates fall) or fixed to floating (accepting variability to capture expected declines).
The strategic question mirrors FX: not "fixed or floating?" but "what fixed/floating *mix* matches our business's natural rate sensitivity?" A firm whose revenues rise with inflation and rates (say, a company with strong pricing power) has a natural hedge and can carry more floating debt. A firm with fixed long-term revenue contracts should skew fixed to match. The elegant move is matching *duration of liabilities to duration and rate-sensitivity of cash flows*—not chasing a rate forecast. CFOs who bet the debt structure on a rate call are speculating; CFOs who match structure to business cash-flow behavior are hedging.
One practical trap: basis risk. Your hedge instrument and your exposure must reference the same underlying. Post-LIBOR transition, a swap indexed to SOFR against debt repriced on a different basis leaves a residual gap. Small in normal times, it widens exactly when markets stress. Audit your hedges for basis mismatch before you rely on them.

A hedging program without governance is a trading desk waiting for a scandal. The infrastructure separates disciplined risk management from career-ending speculation.
The hedging policy is a board-approved document, not a treasury preference. It specifies which exposures are hedged, permitted instruments, minimum and maximum hedge ratios by tenor, approved counterparties and credit limits, and—critically—an explicit prohibition on positions that exceed underlying exposure. That last clause is what separates hedging from betting. Barings, Allied Irish Banks, and a long list of corporate blowups share one feature: someone put on a position larger than the real exposure and called it a hedge. The policy's job is to make that structurally impossible and to define who can authorize exceptions.
Hedge accounting is a choice with consequences. Under IFRS 9 and ASC 815, a properly documented and effective hedge lets you defer gains/losses to OCI (cash-flow hedge) and recognize them when the underlying hits earnings—smoothing reported results. But qualifying is administratively demanding: you must document the hedging relationship at inception, define the hedged item, and demonstrate effectiveness. Fail the test, or skip the documentation, and every mark-to-market swing on the derivative hits net income immediately—even though the offsetting exposure isn't yet recognized. That's how an economically sound hedge produces earnings volatility that ambushes your own guidance. The CFO's decision: is the accounting cost of hedge-accounting compliance worth the earnings smoothing, or is the exposure small enough to let derivatives run through P&L? For a large, recurring program, hedge accounting is worth the discipline. For a one-off, it often isn't.
Counterparty and liquidity risk are the hidden costs. Every forward and swap consumes credit capacity with your banks and may require collateral posting under a CSA when positions move against you. In a sharp market move, a large hedge book that's "winning" is fine—but the losing leg can demand cash collateral precisely when liquidity is tight. Stress-test the *cash* implications of your hedge book, not just its economic value. A hedge that protects earnings but triggers a liquidity call in a crisis has traded one risk for a worse one.
The governance mindset: hedging is a cost center that reduces variance, not a profit center. Any quarter where treasury "made money" on hedging should prompt the same question as a quarter where it "lost money"—did the hedge track the underlying exposure? A hedge book generating standalone profits is a book taking standalone risk.
