Currencies & FX Overview

Efficient handling of CAD ↔ USD conversions matters for Canadian investors allocating to U.S. securities (stocks, ETFs, options) or harvesting U.S. proceeds back into CAD. Small percentage costs repeated over years quietly reduce compounding.


2. Core Concepts (Quick Primer)

  • Exchange / Spot Rate: Interbank price (e.g., 1 USD = 1.3600 CAD). Retail platforms usually wrap a markup.
  • Spread: Difference between bid and ask. Wider = more implicit cost.
  • Markup (Retail FX Spread): Additional hidden percentage above the true interbank rate.
  • Dual‑Listed Security: Same underlying equity/ETF trading in both currencies (e.g., BNS / BNS, DLR / DLR.U).
  • Journaling: Administrative broker action to move positions between CAD and USD sub‑accounts without selling.
  • Settlement (T+2): Standard equity settlement; some brokers permit sale of journaled shares prior to full settlement for well-known Gambit instruments.

3. Simple Conversion Example

Assume you need USD 5,000 and spot is 1.3600 CAD/USD.

MethodImplied RateCAD OutlayEffective Cost vs Spot
Bank FX (2% markup)1.38726,9366,800 × 2% = 136 extra
Norbert’s Gambit (~0.10%)~1.3614~6,807~7 extra
IBKR Direct FX (~0.002%)1.3600–1.3601~6,800~0.50 extra

(Illustrative only; real spreads vary.)


4. Common Pitfalls

  • Converting small amounts (commissions can outweigh savings).
  • Letting a dual‑listed equity sit overnight (price risk increases).
  • Forgetting to compare the final effective rate vs spot (missed learning feedback loop).
  • Assuming all brokers journal instantly—policies differ.
  • Holding across an ex‑dividend date unintentionally.

5. Choosing a Method (Rule-of-Thumb)

AmountTypical Efficient Approach
< CAD 1,000Simplicity > optimization: direct FX ok
1,000–8,000Gambit (DLR/DLR.U) or low‑cost broker FX
8,000–50,000Gambit savings material; watch execution timing
> 50,000Consider liquidity depth; staged orders or direct institutional-like FX if available

6. Tracking Your Effective Rate

  1. Record source currency amount spent.
  2. Record destination currency received.
  3. Compute implied rate (dest ÷ source).
  4. Compare against spot mid at execution time.
  5. Log slippage (%) for future method selection.
