How much of your company's survival depends on things you do not control? For most British Columbia owners, the honest answer in 2026 is: more than they have measured. The trade relationship with the United States remains unsettled, with tariff measures continuing to reshape cross-border costs and pricing. The Canadian dollar swings on commodity and policy news. Demand is steady in some sectors and soft in others. None of this is a crisis on its own — but unmeasured exposure to all of it at once is how otherwise healthy companies get caught out. Risk management is not pessimism; it is the discipline of knowing your exposures before they find you.
This post is a practical playbook covering the three financial risks that most often blindside established BC firms — foreign exchange, concentration, and liquidity — and how to put a measurable buffer against each.
Start by naming your exposures, not your fears
Risk management goes wrong when it stays abstract. "We're worried about tariffs" is not a risk register; it is anxiety. The first job is to translate worry into measured exposure. For each major risk, you want a number: how much of revenue, cost, or cash is exposed, and what happens to profit if the adverse case materializes.
A useful exercise is a one-page exposure map. List your largest risks down the left, and for each one capture three things: the size of the exposure in dollars, the probability you would assign to an adverse move, and the profit impact if it occurs. The risks that combine a large exposure with a plausible trigger are where your attention and capital belong — not the dramatic-but-remote scenarios that dominate conversation.
Foreign exchange: the silent margin leak
If your BC company imports inputs priced in US dollars, exports to American customers, or competes against US-priced goods, the Canada–US exchange rate sits inside your margin whether you manage it or not. A 5 percent move in the loonie can erase a meaningful slice of a thin-margin product line, and it does so quietly — there is no invoice line item called "FX loss."
Three levels of FX discipline, in order of sophistication:
- Measure it. Quantify your annual USD inflows and outflows. A natural offset (USD revenue funding USD costs) is the cheapest hedge of all and may already cover much of your exposure.
- Match it. Where possible, invoice and source in the same currency, or hold a USD account so you are not converting every transaction at the spot rate on a bad day.
- Hedge the residual. For the net exposure that remains, simple forward contracts let you lock a rate for known future purchases or sales, converting an unknown into a budgetable number. The goal is not to speculate on currency — it is to remove currency as a variable from your operating plan.
Concentration risk: the customer or supplier you cannot afford to lose
Concentration is the risk owners most consistently underestimate, because the concentrated relationship usually feels like a strength right up until it becomes a threat. If one customer is 35 percent of revenue, that customer effectively sets your terms, your pricing flexibility, and — if they leave or fail — your solvency. The same logic applies to a single-source supplier whose tariff exposure or disruption you cannot route around.
Measure concentration explicitly:
- Revenue concentration: what share of revenue comes from your top one, three, and five customers? A common warning line is any single customer above 20–25 percent, or top-three above 50 percent.
- Supplier concentration: for each critical input, how many qualified suppliers do you actually have, and how many are in a tariff-exposed jurisdiction?
- Receivables concentration: which customers also dominate your accounts receivable, compounding revenue risk with credit risk?
You will not diversify a concentrated book overnight. But naming the number changes behaviour: it justifies the cost of qualifying a second supplier, it disciplines how much credit you extend to a dominant customer, and it makes the case for the business-development effort to broaden the base before you are forced to.
Liquidity: the buffer that turns a shock into an inconvenience
Profit is an opinion; cash is a fact. A company can be profitable on paper and still fail because a tariff-driven cost spike, a lost anchor customer, and a slow receivables month land in the same quarter. The defence is a deliberate liquidity buffer, sized to your actual volatility rather than a rule of thumb.
Work it in three steps:
- Know your monthly cash burn floor — the fixed obligations (payroll, rent, debt service, source deductions, GST/PST remittances) that must be met regardless of revenue.
- Decide a coverage target — how many months of that floor you want to be able to cover from cash plus undrawn committed credit. For a firm with concentrated revenue or tariff exposure, three to six months is a defensible target.
- Close the gap deliberately — through retained earnings, a right-sized operating line negotiated before you need it (banks lend most readily when you do not), or staged capital spending that preserves cash.
With the Bank of Canada's policy rate stable at 2.25 percent, the carrying cost of holding that buffer is low — making 2026 an inexpensive year to build resilience you may need later.
Worked example: pricing the cost of an unmanaged exposure
Consider two BC firms that import US-dollar components and each have one customer representing 40 percent of revenue. Each does $4,000,000 in annual revenue at a 12 percent operating margin — about $480,000 of operating profit. Now an adverse year arrives: the loonie weakens 6 percent against the USD, lifting import costs, and the anchor customer cuts orders by a quarter.
Scenario A — Pacifica Supply Ltd. measured and buffered. Pacifica had quantified its FX exposure and locked forward contracts covering most of its known USD purchases, so the 6 percent move costs it only about $25,000 rather than the full unhedged hit. It had also spent the prior year broadening its customer base, so the anchor customer is now 28 percent of revenue, and it carries a four-month liquidity buffer. The order cut trims revenue by roughly $280,000 and operating profit by about $34,000, but Pacifica absorbs both, draws nothing on its line, and stays comfortably inside its covenants. A bad year, not a dangerous one.
Scenario B — Westbrook Trading Inc. left it unmanaged. Westbrook hedged nothing and never diversified. The FX move adds roughly $70,000 to its cost base. The anchor customer — still 40 percent of revenue — cuts orders by a quarter, removing about $400,000 of revenue and roughly $48,000 of operating profit, while fixed costs barely move. With only three weeks of cash on hand, Westbrook is forced to draw its line to the limit, breaches a debt-service covenant, and spends the quarter negotiating with its bank instead of running the business.
Same external shock, same starting margin. The difference in outcome is entirely the work done before the shock — measured exposures, a broader customer base, a sized buffer. Risk management is not what you do in the storm; it is what you built in the calm.
Key takeaways
- Translate vague worry into a measured exposure map: dollar size, probability, and profit impact for each major risk.
- FX quietly erodes margin — measure net USD exposure, match currencies where you can, and hedge the residual with simple forwards.
- Concentration is the most underestimated risk; track top-customer and single-supplier shares and diversify before you are forced to.
- Size a liquidity buffer to your real cash-burn floor; at a stable 2.25 percent rate, holding that buffer is cheap.
- Resilience is built in calm quarters, not improvised in bad ones.
A risk you have measured is a problem you can manage; a risk you have only worried about is a surprise waiting to be scheduled.
