Mispriced FX is costing PSPs deals

By Dor Golan, Co-founder & CEO, Grain

TL;DR:

FX pricing has become a competitive blind spot for many PSPs. Defensive, static pricing that was designed for safety now suppresses conversion, limits which merchants and verticals PSPs can serve, and quietly hands market share to competitors with more dynamic pricing models.

---------------------------------------------

Payment service providers are losing deals every day - not because of fraud, uptime, or checkout UX, but because their FX pricing is quietly uncompetitive. They’ve spent years building sophisticated fraud detection, real-time settlement networks, and seamless checkout experiences. Yet when it comes to foreign exchange, particularly among merchant acquirers and card processors, most are still using the same defensive playbook from a decade ago: add a margin, lock it in for the day, and hope nothing moves too dramatically.

The assumption has always been straightforward: currency volatility is dangerous. The safest response has been to price conservatively, build in buffers, and pass the cost along. It’s a safety-first approach that feels responsible, the kind of decision that rarely gets questioned internally, even when it quietly undermines competitiveness.

But here’s the problem: that safety net is expensive. In an increasingly competitive payments landscape, it’s already costing PSPs more business than the currency risk it was designed to protect against.

The invisible engine of competitive pricing

When a PSP - whether a merchant acquirer, payment facilitator, or gateway provider - sets its FX pricing, it’s making a direct decision about market positioning. Price too high to protect against volatility, and you lose deals to competitors. Price too tight, and you expose yourself to risk. In practice, many PSPs, particularly in merchant acquiring, have resolved that tension by choosing safety over growth.

The problem is that “safety” compounds over time. Every defensive margin added to protect against currency swings becomes a permanent handicap in merchant acquisition. When a competitor can quote a rate even 20–30 basis points better, that’s often enough to swing a deal,  and across high-volume, low-margin verticals like e-commerce or travel, those lost deals quickly add up to meaningful lost revenue.

The defensive margin that was supposed to protect the business ends up costing it business. It’s not a hedge - it’s a tax on growth. And most PSPs don’t realize how much market share they’re already giving up because of it.

"Defensive FX pricing isn't a hedge - it's a tax on growth."

Static pricing in a dynamic market

The mechanics of defensive pricing haven’t changed much for many PSPs, particularly merchant acquirers handling card transactions. These processors typically set rates in the morning, often around the 8 am GMT fixing, and hold those rates for the rest of the day. It’s predictable. It’s simple. And in a market that moves by the hour, it’s a competitive disadvantage.

Currency markets don’t move on a daily schedule. Rates shift throughout the day based on volume flows, geopolitical headlines, and trading activity across time zones. A merchant acquirer that locked in pricing at 8 am can easily be quoting an uncompetitive rate by 2 pm, not because markets moved against them, but because their pricing couldn’t move with the market.

This creates two problems. First, you’re leaving money on the table when markets move in your favor, revenue that could have improved margins or been passed along to win price-sensitive merchants. Second, you’re locked into weaker pricing positions while competitors with dynamic pricing adjust in real time.

The operational cost of playing it safe

Beyond pricing competitiveness, a defensive FX strategy creates two less visible but equally expensive problems: operational complexity and market constraints.

On the operational side, multi-currency reconciliation quickly becomes a bottleneck. Different settlement rails, currencies, and timing all need to be tracked, matched, and reported. That overhead pulls engineering resources away from merchant-facing features and into back-office reconciliation. Finance teams spend hours chasing discrepancies across currency pairs instead of analyzing growth opportunities. And when PSPs can’t provide clean, unified reporting across currencies, it erodes merchant trust and adds friction to what should be seamless relationships.

On the market side, settlement timing becomes a structural growth constraint. Cross-border transactions often involve gaps between payment collection and settlement, sometimes stretching days. Most PSPs respond with defensive pricing, which effectively prices them out of high-growth merchant segments. Travel, subscription, and marketplace models frequently involve longer settlement cycles, higher cancellation rates, or delayed payment flows. PSPs that can’t price competitively in these environments aren’t just losing deals — they’re handing over entire markets to more sophisticated competitors.

PSPs that have simplified FX management - often by consolidating it into a single, dynamic pricing layer - are seeing real operational leverage and market expansion. They’re not just reducing costs; they’re unlocking merchant segments that others simply can’t serve profitably.

A shift in mindset

The payments industry has always been good at managing risk: Fraud risk. Credit risk. Operational risk. But when it comes to FX, the instinct has been to avoid it, rather than use it strategically.

That’s starting to change. The most forward-thinking PSPs are no longer asking, “How do we protect ourselves from currency volatility?” They’re asking, “How do we use smarter FX management to win more merchants and grow transaction volume?”

It’s a fundamental reframing. FX isn’t just a cost center to be minimized - it’s a growth lever. PSPs that figure out how to offer better rates, more flexible terms, and cleaner operations around multi-currency transactions are positioned to capture disproportionate share as the market continues to scale.

The ones still playing it safe aren’t avoiding risk, they’re avoiding growth. In an increasingly competitive market, playing defense on FX while competitors use it as a pricing weapon is the riskiest strategy of all. The PSPs pulling ahead are the ones using FX as a tool to acquire merchants faster, retain them longer, and price more competitively. ---------------------------------------------
