Currency expertise built over 30 years. Applied to your business.
Castle Currency was founded on a simple belief: businesses deserve better than what banks and brokers give them on currency.
Most currency providers are sales organizations. They hire salespeople, give them a pricing sheet, and tell them to make calls. The "expertise" stops at quoting a rate.
Castle Currency was built differently.
The idea started on a flight home from Europe in 2000. Founder Jeffrey Boyko had spent years trading for institutional clients, working under one of the top-ranked currency traders in the world. On that flight, reading about how the weak Canadian dollar was crushing businesses back home, he saw a problem worth solving: bring real currency expertise to the companies that needed it but couldn't afford a dedicated specialist.
What Jeff had seen over and over was consistent: companies obsessed over getting a slightly better rate while ignoring the much larger cost of poor timing, reactive decisions, and a complete absence of structure around their currency activity. The rate your provider charges matters, but it's a fraction of what you lose when conversion decisions are made without a plan.
Castle Currency was built to fix that.
Today, Castle Currency combines an online currency platform backed by a Fortune 500 settlement partner, with 30 years of hands-on currency expertise. We work directly with importers, exporters, and finance teams to improve how currency decisions are made, not just how transactions are processed.
About Jeffrey Boyko, CFA, P.Eng.
Jeffrey Boyko is the founder and CEO of Castle Currency. His background spans currency trading, risk management, engineering, and multi-currency operations. He holds both the Chartered Financial Analyst (CFA) designation and a Professional Engineering (P.Eng.) credential, a combination that brings both financial rigor and systems-level thinking to how businesses handle currency.
Jeff's career includes serving as a Head Currency Trader in Monaco, working alongside one of the top-ranked currency traders in the world. That experience, combined with 30 years of working with businesses of all sizes, shaped the Castle Currency approach: improve the quality of the decision, not just the cost of the transaction.
When you work with Castle Currency, you work with Jeff and his team directly. Not a call center. Not a junior rep reading from a script.
Our Approach
- We are currency experts who consult, not salespeople who transact.
- We think in systems, process, and measurable outcomes - not sales targets.
- We tie currency decisions to your margins and budget targets, not to market predictions.
- We provide direct access to senior currency professionals.
- We don't remove uncertainty by watching markets - we remove it by helping you have a plan.
Our Infrastructure
All transactions are processed through our Fortune 500 settlement partner (one of the world's largest non-bank currency providers) and a division of an S&P 500 company. Your money moves through institutional-grade settlement infrastructure with the security, compliance, and reliability that comes with it.
Castle Currency focuses on what the infrastructure can't provide: the expertise, guidance, and structure that turns currency from a back-office task into a properly managed part of your business.
