How do remittance flows from South Africa to the US and vice versa affect the ZAR/USD exchange rate?

Why Care About Remittances and the ZAR/USD Rate?

If you’ve ever tried sending money from Johannesburg to family in New York, or the other way around, you’ll know that exchange rates matter—a lot. The ZAR/USD rate can swing wildly, and at first glance you might wonder if all those cross-border transfers add up to a force capable of swaying the currency. I got curious about this myself after a particularly bad rate on a transfer to a friend studying at Rutgers—so I dug into data, spoke to economists, and tested out a few platforms.

Understanding the Mechanics: How Remittance Flows Work

Let’s break it down to the basics—remittances are private transfers, usually from individuals working in one country to family or associates in another. For South Africa and the US, the flows are not as colossal as, say, US-Mexico, but they’re still material. In 2022, World Bank data showed South African inbound remittances at around $1.1 billion, with outbound flows (mostly to neighboring countries) much higher, but flows to the US are a small part of the pie (World Bank Remittance Data). Now, the key thing: When someone in SA sends money to the US, they’re selling ZAR to buy USD—so, in theory, this should weaken the rand and strengthen the dollar. Conversely, remittances going the other way require selling USD to buy ZAR, supporting the rand. But does this really move the needle?

Real-World Impact: Measurability and Market Size

Here’s where it gets interesting. The daily turnover in the ZAR/USD foreign exchange market is massive—well over $15 billion per day according to the Bank for International Settlements (BIS Triennial Survey 2022). In comparison, annual remittance flows between South Africa and the US are a rounding error. I remember chatting with a trader at a big South African bank—he laughed and said: “Retail flows? We don’t even see them. Maybe if there’s a spike around Christmas, but even then, it’s noise compared to what the corporates and asset managers are moving.” That said, on days with very low market liquidity (think public holidays), a sudden surge in remittances can have a micro-effect on pricing, especially for smaller money transfer operators.

Practical Demo: Sending a Remittance and Watching the Rate

Here’s a quick walk-through from my own experience: 1. I logged into Wise (formerly TransferWise), set up a ZAR to USD transfer for R10,000. 2. The platform quoted me a rate “guaranteed for 30 minutes”—let’s say ZAR18.20/USD. 3. I checked Bloomberg and saw the live interbank was ZAR18.18/USD—so the retail rate included a slight margin. 4. I completed the transfer at 2:00 PM SA time. 5. Looking at a Bloomberg ZAR/USD tick chart for that time, there was no visible move at all (see attached screenshot below). So, my modest transfer had zero observable impact, confirming what the pros say: for the ZAR/USD pair, remittances are too small to matter at the macro level.

Remittances in the Broader Economic Picture

That’s not the end of the story, though. If you zoom out, sustained, long-term trends in remittance flows can affect current account balances, which do matter for currency valuation. The South African Reserve Bank (SARB) and the US Federal Reserve both monitor these flows as part of the “secondary income” line in the balance of payments (SARB Quarterly Bulletin). But for South Africa, remittances to the US are a tiny slice compared to, say, mining exports or portfolio flows. If hypothetically, South Africa started exporting huge numbers of skilled workers to the US who then remitted billions back, you could see a cumulative impact—but today, that’s not the reality.

Expert Perspective: Industry Voices

I put the question to Dr. Nomusa Mthembu, a Johannesburg-based currency strategist. Her take:

“Remittances create a steady, predictable demand for foreign exchange, but they’re dwarfed by trade and investment flows. In the ZAR/USD market, it’s like tossing a pebble into the sea. But, for families or small businesses, the exchange rate on their remittance can make a significant difference to their monthly budget.”

So, while individuals feel every cent, the market as a whole barely notices.

Case Study: A Surge in Remittances—Would It Matter?

Let’s try a what-if. Suppose a sudden policy change led to a doubling of remittances from South Africa to the US. Would this move the ZAR/USD rate? According to IMF modeling (IMF Working Paper 16/33), only very large and persistent changes in remittance flows (as a share of GDP) have measurable impacts on exchange rates in emerging markets. For South Africa, you’d need flows to multiply several times over to see even a marginal effect.

Regulatory Context: How Money Flows Are Tracked

Both the US and South Africa have strict rules around cross-border financial transactions. In South Africa, the Financial Surveillance Department of SARB monitors all outward remittances, requiring documentation and reporting under Exchange Control Regulations (see SARB Financial Surveillance). In the US, remittance providers must comply with the Bank Secrecy Act and report through the Financial Crimes Enforcement Network (FinCEN). These controls ensure flows are visible to authorities, but they do not attempt to “steer” the currency rate via remittance monitoring.

Comparing “Verified Trade” Standards: US vs. South Africa

For broader context, here’s a quick table comparing how “verified trade” is handled in cross-border payments by the US and South Africa:

Country	Standard Name	Legal Basis	Executing Agency	Typical Documentation
South Africa	Balance of Payments Reporting (BoPCode)	Exchange Control Regulations, Currency and Exchanges Act, 1933	SARB Financial Surveillance Dept	Invoice, customs forms, SARS clearance
United States	OFAC/FinCEN Screening	Bank Secrecy Act, OFAC Sanctions	FinCEN, Federal Reserve	Remittance receipts, sender/receiver ID

This “verified trade” requirement mostly impacts business payments, but for large remittances, documentation may be required. It rarely impacts the spot exchange rate except in cases of fraud or regulatory freezes.

Simulated Dispute: How Standards Diverge

To illustrate, imagine a US business pays a South African supplier, but the documentation is incomplete. The US bank, under FinCEN rules, may withhold the transfer. In South Africa, when the funds arrive, the SARB’s systems require a BoP code matching the trade invoice. If there’s a mismatch, the funds can be frozen pending further review—a headache I witnessed firsthand when helping a friend’s import/export business.

Conclusion and Recommendations

So, does the movement of remittance money between South Africa and the US have a measurable impact on the ZAR/USD exchange rate? In the grand scheme—no. The volumes are too small relative to the daily churn of the FX market. However, on an individual level, the exchange rate at the moment of transfer matters a lot, and the costs and delays imposed by regulatory oversight can be significant. If you’re sending or receiving money, your best move is to watch rates, use a transparent provider, and keep documentation handy in case compliance questions arise. For those interested in the macro picture, keep an eye on trade and investment flows for real clues about where the rand is headed. If you want to dig deeper, look at the SARB’s quarterly bulletins, the IMF’s global remittances database, or try tracking your own transfers against Bloomberg FX charts. And if you ever have to argue with a compliance officer about BoP codes—good luck, and maybe bring coffee.
