Managing Currency Risk When Buying ADRs

American Depositary Receipts let you buy foreign stocks through US exchanges with dollar-denominated prices and normal settlement. But the convenience obscures a critical reality: your total return depends on two separate components. The underlying stock can rise 15% in local currency terms while your ADR position gains only 8%—or loses money entirely—if the foreign currency depreciates against the dollar. In 2022, the MSCI EAFE Index fell 14.5% in USD terms but only 8.4% in local currency terms. The difference was pure currency drag. The practical point: you cannot evaluate ADR performance without decomposing returns into stock performance and FX impact.

Sponsored vs. Unsponsored ADRs (Why Structure Matters)

ADRs come in two flavors with meaningfully different characteristics.

Sponsored ADRs involve a formal agreement between the foreign company and a depositary bank (typically BNY Mellon, JPMorgan, or Citibank). The company participates in creating the program, provides financial disclosures, and pays the depositary's fees directly.

Sponsored ADR levels:

Unsponsored ADRs are created by depositary banks without company involvement. Multiple banks can issue competing ADRs for the same underlying stock, leading to potential liquidity fragmentation. The foreign company has no disclosure obligations to US investors beyond its home market requirements.

Why this matters: Unsponsored ADRs typically have wider bid-ask spreads (often 0.5-1.5% vs. 0.1-0.3% for sponsored Level II/III), less reliable dividend timing, and no guarantee the company will cooperate with shareholder communications. If you hold an unsponsored ADR, expect higher friction costs and information delays.

Currency Impact on Returns (The Math You Need)

Your ADR return combines two independent components:

The formula: ADR Return = (1 + Local Stock Return) × (1 + Currency Return) - 1

Example: Toyota Motor (TM)

You buy TM at $175 when USD/JPY = 145. One year later:

• Toyota stock rises from ¥2,500 to ¥2,750 (local return: +10.0%)
• USD/JPY moves from 145 to 155 (yen depreciates 6.9% against dollar)

Your ADR calculation:

• Local return: +10.0%
• Currency return: (145/155) - 1 = -6.5%
• ADR return: (1.10) × (0.935) - 1 = +2.9%

The yen weakness cost you 7.1 percentage points of return (10.0% - 2.9%). You participated in Toyota's business success but captured less than a third of it in dollar terms.

Reverse scenario (currency tailwind):

Same Toyota local return (+10%), but USD/JPY moves from 145 to 135:

• Currency return: (145/135) - 1 = +7.4%
• ADR return: (1.10) × (1.074) - 1 = +18.1%

Now currency adds 8.1 percentage points to your return. The durable lesson: currency can double your gains or eliminate them entirely—and predicting FX moves is notoriously difficult even for professionals.

Hedging Options for Retail Investors

Most retail investors cannot cost-effectively hedge individual ADR positions. Here are your realistic options:

Option 1: Currency-hedged international ETFs

Instead of individual ADRs, use hedged ETFs that systematically neutralize FX exposure:

Hedging costs depend on interest rate differentials between countries. When US rates exceed foreign rates (as with Japan), hedged products pay the differential to maintain the hedge—this is a real cost, not a free lunch.

Option 2: Accept unhedged exposure strategically

For long-term holders (10+ years), currency moves tend to be mean-reverting. The US dollar index (DXY) has traded in a 70-120 range over the past 50 years with no permanent trend. If you can tolerate multi-year periods of currency drag, the expected long-term cost of leaving positions unhedged is low.

Option 3: FX futures or forwards (institutional only)

Direct currency hedging requires minimum contract sizes ($100,000+ for CME FX futures), margin accounts, and ongoing roll management. The operational complexity and costs make this impractical for positions under $500,000 in a single currency exposure.

The practical point: For most retail investors, the choice is between (a) accepting FX volatility in individual ADRs or (b) using hedged ETFs for broad international exposure. Position sizing is your main tool—don't let any single-currency exposure exceed 15-20% of your international allocation.

ADR Fees and Dividend Withholding (The Hidden Costs)

ADRs carry two categories of costs that reduce your effective return.

Depositary fees:

Depositary banks charge $0.01-0.05 per share per year for sponsored ADRs (passed through to holders via dividend deductions) and may charge custody fees for unsponsored ADRs. On a $50 ADR with a 2% yield, a $0.03/share fee represents 6 basis points of annual drag.

Dividend withholding taxes:

Foreign governments withhold taxes on dividends before they reach US investors. Rates vary by country and can be reduced via tax treaties:

Example: Swiss ADR dividend calculation

Nestle (NSRGY) pays a CHF 3.00 dividend when USD/CHF = 0.88:

• Gross dividend: CHF 3.00 × 0.88 = $2.64
• Swiss withholding (35%): -$0.92
• Depositary fee ($0.02): -$0.02
• Net received: $1.70

You receive only 64% of the gross dividend. The 15% excess withholding (35% - 20% treaty rate) is theoretically recoverable via Swiss tax authorities, but the paperwork is complex and often impractical for small positions.

Tax credit considerations:

In taxable accounts, you can claim a foreign tax credit for withholding up to 15% (the treaty rate for most countries). Excess withholding beyond the treaty rate requires filing for a refund with the foreign government—often not worth the effort for amounts under $1,000.

ADR Ratio Adjustments and Corporate Actions

ADRs represent a fixed ratio of underlying shares, which creates complications during corporate actions.

Common ratios:

• 1 ADR = 1 underlying share (most Level II/III ADRs)
• 1 ADR = 10 underlying shares (common for Japanese stocks)
• 1 ADR = 0.5 underlying shares (used when local share prices are high)

Ratio adjustments: When underlying shares split or consolidate, the depositary can adjust the ADR ratio rather than splitting ADR shares. This means your share count stays constant while the ADR's reference to underlying shares changes.

Rights offerings: Foreign companies frequently issue discounted shares to existing holders. ADR holders receive the economic equivalent, but timing delays of 2-4 weeks are common, and you may receive cash in lieu of fractional rights.

ADR Selection Checklist

Before buying any ADR, verify:

Essential (high ROI):

• Sponsorship level (Level II/III preferred for liquidity and disclosure)
• Daily trading volume (>100,000 shares for tight spreads)
• Depositary fee schedule (check investor relations or depositary bank website)
• Dividend withholding rate for your country pair

High-impact (for income investors):

• Treaty rate eligibility (requires proper W-8BEN filing)
• Dividend payment frequency and typical timing delays
• Currency volatility of underlying (JPY and GBP historically most volatile vs. USD)

Optional (for large positions):

• Evaluate hedged ETF alternatives for broad regional exposure
• Calculate break-even holding period for currency mean reversion
• Consider geographic concentration across all ADR holdings

Next Step (Put This Into Practice)

Calculate the currency component of your existing ADR positions over the past year.

How to do it:

1. Find your ADR's 1-year price return (Yahoo Finance or broker statement)
2. Find the underlying stock's 1-year return in local currency (use the foreign exchange's website or Bloomberg)
3. Subtract local return from ADR return to isolate currency impact

Example calculation:

• ASML (Netherlands) ADR return: +28%
• ASML local return (Amsterdam): +32%
• Currency impact: 28% - 32% = -4% (euro weakness vs. dollar)

Interpretation:

• Currency impact under ±3%: Minimal drag, continue monitoring
• Currency impact -3% to -10%: Meaningful headwind, evaluate position size
• Currency impact beyond ±10%: Currency is dominating returns—decide if you're making a currency bet intentionally

Action: If any single-country ADR exposure exceeds 20% of your international allocation, consider whether concentrated currency risk aligns with your thesis.
