How Exchange Rate Pass-Through Actually Works

When the ringgit weakens against the dollar, your grocery bills don’t just jump overnight. There’s a whole mechanism behind how currency movements translate into the prices you pay at checkout. Understanding exchange rate pass-through is key to grasping why imported goods cost what they do.

The Basic Mechanism

Exchange rate pass-through isn’t complicated once you break it down. When a currency weakens, imports become more expensive for local importers. But here’s the thing — they don’t always pass 100% of that cost increase to consumers. Sometimes they absorb part of it. Sometimes they pass it through completely. It depends on market competition, supply chain factors, and profit margins.

Malaysia imports about 40% of its goods, making this process especially important. When the ringgit depreciates against major currencies like the USD, the impact ripples through everything from electronics to food to fuel. But the speed and magnitude of these price increases vary wildly depending on the product and the importer.

Three Key Factors That Determine Pass-Through

The extent of pass-through depends on three major factors. First, there’s market structure. In highly competitive markets with many suppliers, companies can’t easily raise prices because customers will switch to competitors. You’ll see lower pass-through here.

Second, there’s the nature of the product itself. Essential goods like food and fuel tend to have higher pass-through because demand doesn’t drop much even when prices rise. People still need to eat and drive. Luxury goods have lower pass-through because consumers can cut back when prices spike.

Third is the importer’s ability to adjust. Large corporations with diversified sourcing can shift production or source from different countries. Smaller importers get stuck. They either absorb the cost hit or pass it through completely because they’ve got no other options.

Real example: When the ringgit fell 15% in 2015, imported car prices didn’t rise 15%. They rose maybe 5-8% because manufacturers absorbed losses to keep market share. But imported vegetables? Prices reflected nearly the full currency hit because farmers had no negotiating power.

How Pass-Through Happens Over Time

01

Immediate Impact (Days to Weeks)

Currency moves first. The ringgit weakens, and importers immediately see their dollar costs rising. But prices don’t change overnight. There’s a lag because most supply contracts are fixed for specific periods. Distributors and retailers have inventory at the old price point.

02

Partial Adjustment (Weeks to Months)

Importers start ordering new stock at the new rates. Some retailers and wholesalers begin raising prices gradually. Not all the way though — they’re testing price sensitivity and protecting margins. You might see 30-50% of the currency move reflected in prices during this phase.

03

Full Adjustment (Months)

Eventually the full impact flows through the system. Old inventory is gone. All new orders reflect the new exchange rate. Prices stabilize at their new level. The complete pass-through might be 60-100% depending on the factors we discussed earlier.

Measuring Pass-Through in Malaysia

The Bank Negara Malaysia tracks import prices through various indices. The Trade-Weighted Currency Index (TWCI) measures the ringgit’s strength against Malaysia’s main trading partners. When this index moves, economists expect certain changes in import prices depending on historical pass-through rates.

Different sectors show different pass-through rates. Manufacturing and machinery imports typically show 70-85% pass-through. Agricultural products are higher, around 80-90%. Energy products are nearly 100% because they’re globally priced in dollars. Finished consumer goods show the lowest pass-through at 40-60% because of competitive pressures and brand loyalty.

What’s interesting is that pass-through isn’t symmetric. When the ringgit strengthens, importers don’t always cut prices by the same percentage they raised them. Prices tend to be “sticky downward” — they go up quickly but come down slowly. This means consumers bear the brunt of depreciation but don’t fully benefit from appreciation.

Why This Matters for Consumers

Shopping Smarter

Understanding pass-through helps you anticipate price changes. When you see the ringgit weakening in the news, you know food and fuel prices will likely follow in the coming weeks. Some products adjust faster than others. This knowledge lets you plan purchases strategically.

Business Planning

For businesses relying on imports, understanding pass-through timing is crucial. You can forecast costs better. You’ll know when price increases are coming and can adjust your own pricing strategy accordingly. This is especially important for retailers with thin margins.

Policy Understanding

When BNM adjusts interest rates or intervenes in currency markets, they’re partly trying to manage pass-through. Higher rates strengthen the ringgit, which keeps import prices down. Understanding this helps you grasp why central banks do what they do and what it means for your wallet.

Economic Awareness

Pass-through affects inflation rates, which impacts interest rates on loans and savings. A ringgit depreciation that causes high pass-through means higher inflation. This eventually leads to higher borrowing costs. Understanding the mechanism helps you see the bigger economic picture.

The Takeaway

Exchange rate pass-through isn’t instant or complete. It’s a complex process influenced by market structure, product type, and timing. When you see currency movements in the news, don’t expect prices to move in lockstep immediately. There’s always a lag.

The Malaysian economy is particularly sensitive to this because we import so much. A 10% ringgit depreciation doesn’t mean a 10% price increase across the board. Some things rise 15%. Others rise just 3%. Understanding these differences helps you navigate economic changes more effectively.

Keep an eye on the Trade-Weighted Currency Index and BNM’s policy moves. They’re early signals for price changes coming down the pipeline. And remember — while exchange rate pass-through is real and important, it’s not the only factor affecting prices. Supply disruptions, demand shifts, and competitive dynamics matter too.
