South Africa vs Turkey
The two most-cited EM FX stress cases, orthodox SARB inflation targeting versus CBRT regime shifts.
Structural Relationship
South Africa and Turkey are two of the most-cited examples in emerging-market currency and credit research because both have suffered recurring FX crises, yet for opposite reasons. South Africa is a 380-billion-dollar commodity-exporting economy with a credible inflation-targeting regime at the South African Reserve Bank but persistent structural growth problems (electricity shortages, unemployment above 30 percent, limited industrial capacity). Turkey is a 1-trillion-dollar economy at the crossroads of Europe and the Middle East with a dynamic private sector but a central bank that has repeatedly abandoned orthodox monetary policy, most notably between 2021 and 2023 under President Erdogan's demand that the CBRT cut rates to fight inflation, an approach that pushed the lira from 8 to 30 per dollar before orthodoxy was partially restored under Governor Erkan and her successor.
Both currencies have experienced large drawdowns against the dollar in the 2010s and 2020s, but the drivers differ. The rand is a high-beta risk asset that moves with global commodity prices, Chinese demand, and US dollar cycles, amplified by South African fiscal stress and loadshedding headlines. The lira is a policy-regime-risk currency; it moves based on whether markets believe the CBRT will run a positive real-rate regime. Between 2021 and 2023, lira weakness was driven almost entirely by policy choice rather than by trade or commodity fundamentals. After the mid-2023 pivot toward orthodox policy, real rates returned to positive territory and the lira stabilised at a substantially weaker level but with functioning FX market depth.
Structurally, South Africa is the G20's most commodity-dependent economy (gold, platinum-group metals, coal), while Turkey is one of the most trade-integrated EM economies with Europe, running substantial goods and services exports into the Eurozone. Rand weakness helps commodity-export earnings; lira weakness helps tourism and export receipts but explodes import bills.

Current Divergence Read
Current focus is on whether the CBRT maintains orthodox real-rate discipline, South African fiscal slippage and loadshedding, and the relative carry each currency offers adjusted for volatility. After the 2023 pivot, the lira's carry yield has exceeded the rand's, but lira volatility remains elevated. Watch the SARB repo rate, the CBRT 1-week repo rate, both headline CPI prints, and both currencies against the dollar.
Historical Episodes
Frequently Asked Questions
What made Turkey's 2021 to 2023 lira crisis different from a normal EM crisis?+
It was a policy-choice crisis rather than an external shock. The CBRT cut rates into rising inflation at the President's direction, producing deeply negative real rates and triggering a capital-flight spiral. No external shock explains the magnitude of the lira move; the cause was domestic.
Why is the SARB considered credible despite rand volatility?+
SARB has maintained positive real rates through virtually every cycle since the early 2000s and has not bent to political pressure even during loadshedding and fiscal stress. Credibility is about the central bank's reaction function; rand volatility reflects South Africa's macro backdrop, not SARB policy inconsistency.
How does loadshedding affect the rand?+
Chronic electricity shortages reduce industrial output and investor sentiment, widening the South African risk premium. Each step-up in loadshedding intensity since 2018 has coincided with rand weakness versus developed-market peers.
Is the lira a carry trade again post-2023?+
Technically yes, as real rates turned positive in 2024. But realised volatility remains high and the political fragility of orthodox policy under any future intervention means carry positions are still risk-asset trades rather than pure income plays.
Which is more sensitive to global risk-off?+
The rand. It is a high-beta commodity currency that moves almost in lockstep with risk-off EM FX selling. The lira has more idiosyncratic drivers and can rally or sell off against global EM trends depending on CBRT signalling.
What do both crises teach about EM monetary credibility?+
That real rates, not nominal rates, are the variable markets price. South Africa paid growth costs to maintain positive real rates and kept its inflation-targeting credibility. Turkey sacrificed positive real rates and paid the cost through currency collapse and delayed disinflation.
