The Setup: Why Everyone Is Suddenly Excited About Brazil and South Africa

The Federal Reserve projected a federal funds rate of 3.6% to 3.9% by end of 2025, according to AInvest. That's meaningfully lower than where we've been. When U.S. rates fall, the dollar weakens. When the dollar weakens, investors go hunting for yield elsewhere.

That "elsewhere" right now is emerging markets.

The carry trade is simple: borrow in U.S. dollars at low rates, then invest in currencies offering dramatically higher returns. Brazil's real is yielding 15%. The South African rand is at 8.5%. Egypt's pound is sitting at 12%. Compare that to what you're earning in a U.S. money market fund and you can see why institutional money is moving.

The Big Players Are Already In

The money is already moving.

JPMorgan upgraded emerging market currencies to "overweight" in July 2025, citing a 12-year high in the volatility differential between EM and G10 currencies, according to AInvest. The largest U.S. bank by assets made a significant call.

Neuberger Berman and Aberdeen Group have both deepened exposure to Latin American and African markets. Leveraged funds have pushed bullish positions in the Mexican peso to their highest level in nearly a year.

Bloomberg reported the Brazilian real and South African rand are among the top favorites in the carry trade revival, with institutional optimism building into 2026.

What Mainstream Coverage Is Missing

The financial press covers the upside while burying the risks.

The same AInvest analysis that highlights these yields also notes that Trump's 50% tariff on Brazilian exports has directly disrupted supply chains tied to the very economies investors are betting on. Brazil and Mexico are both exposed. The Mexican peso has seen volatility spike despite the bullish positioning — a contradiction that deserves attention.

China, Canada, and the EU have all responded with retaliatory measures. The global trade environment is fractured, and the emerging markets catching hot money inflows are some of the same ones getting hit by trade policy chaos. Investors are essentially betting the tariff damage is already priced in. History says that's a gamble that ends badly at least half the time.

The Fed's Role — and Its Limits

Markets are pricing in a 60% probability of one or two 25-basis-point cuts by December 2025, according to fed funds futures data cited by AInvest. The Fed's own projections see 0.50 percentage points in cuts in 2025 and 0.75 percentage points in 2026.

U.S. inflation was still running at 2.7% in June 2025. The Fed is not declaring victory. Fed Chair Jerome Powell has been explicit about moving carefully. If inflation re-accelerates — say, because tariffs jack up consumer prices — those rate cut expectations evaporate overnight.

When that happens, the carry trade unwinds. Fast. Painfully. A preview came in August 2024 when yen-funded carry trades collapsed in a single week, wiping out months of gains and triggering global equity selloffs.

The Exposure

Carry trade flows affect currency values globally. A strong real or rand means Brazilian and South African goods get more expensive for their own citizens. Capital flooding out of the U.S. seeking yield puts upward pressure on U.S. borrowing costs over time if it becomes a sustained trend.

Your 401(k) almost certainly has emerging market exposure. Most target-date funds and international index funds do. When the carry trade works, those holdings benefit. When it unwinds violently, those holdings crater.

Brazil's central bank is trying to hold 15% interest rates to fight inflation while simultaneously absorbing tariff shocks. Mexico is watching its currency get whipsawed by policy threats from Washington. These are not stable backdrops for a yield-chasing strategy.

The Revival and the Risk

The carry trade revival is real. The data supports the enthusiasm — for now. JPMorgan, Neuberger Berman, and Aberdeen aren't making these moves blindly.

The conditions that make this trade attractive are also the conditions that make it fragile. Fed policy uncertainty plus trade war disruption plus EM political risk is a combination that has torched investors before.

Watch the Fed. Watch inflation. And watch what happens to those tariff negotiations. The carry trade window can close faster than anyone expects.
