April is historically one of the strongest months for global equity markets — and in 2026 it arrives with an unusually powerful macro tailwind. The Trump-Iran two-week ceasefire announced on April 7 triggered the sharpest single-session rotation in the country ETF universe since the war began on February 27. Brent crude fell more than 15%. Prediction markets on Polymarket price a US recession by end-2026 at 30.5% — down from 36% before the ceasefire. The Fed April meeting is priced at 98.45% no change, per Polymarket data as of April 8.

Seasonality does not override macro. But when both signals align in the same direction simultaneously — as they do now for the first time since February 27 — the combination is analytically significant. All seasonality figures in this article are sourced directly from the CountryETFTracker SeasonalityCache, using up to 20 years of monthly return data. Month index '3' = April. These are exact historical figures, not estimates.

Why April Is Structurally Strong for Country ETF

s

April is the month when Q1 earnings season opens in the US and begins flowing through to international benchmarks. End-of-quarter institutional rebalancing is complete, and fresh capital is deployed. For country ETFs specifically, April captures several recurring structural drivers:

• Post-Q1 earnings rerating in semiconductor-heavy markets (South Korea, Taiwan)
• Japan's fiscal year opening (fiscal year begins April 1) — triggering GPIF allocation resets and foreign dividend repatriation
• European dividend season boosting high-yield markets (Spain, Italy, UK)
• EM capital inflows as DM institutional allocations reset for Q2

Benzinga noted on April 8 that the Dow surged over 2% as "bullish April seasonality kicks in" alongside the ceasefire — explicitly confirming the seasonal-macro alignment.

1. Greece (GREK) — Highest April Average Return in the Univers

e

The Global X MSCI Greece ETF (GREK) has the strongest April seasonal record among all country ETFs tracked on CountryETFTracker: an average return of +4.88% with a 78.6% win rate across 14 years of data. This is not a small-sample anomaly — across 14 Aprils, GREK has been positive in 11 of them, with standout returns including +16.4% in 2013, +12.2% in 2015, +10.0% in 2018, +9.2% in 2020 and +9.6% in 2021.

The structural driver is Greece's banking sector, which dominates GREK's composition (National Bank of Greece, Alpha Bank, Eurobank). Greek banks consistently announce dividend declarations in March-April, triggering institutional buying ahead of ex-dividend dates. The banking sector's high dividend yield creates a recurring seasonal flow dynamic.

In 2026, GREK's April setup is amplified by the ceasefire. Greece is a net energy importer that lost -9.63% from February 27 to March 31 — the April session of April 8 alone delivered +6.64%, its largest single-day gain in years. At 8.42x forward P/E — a 50.8% discount to the MSCI ACWI at 17.12x — GREK is also one of the deepest-value liquid country ETFs in Europe. Greek shipping companies' Hormuz exposure adds an additional direct ceasefire catalyst: Greece controls approximately 20% of global tanker capacity.

2. Saudi Arabia (KSA) — Highest Win Rate, But Oil Headwin

d

The iShares MSCI Saudi Arabia ETF (KSA) has the highest April win rate in the seasonality dataset: 80% win rate with an average return of +4.14% across 10 years of data. In 8 of the last 10 Aprils, KSA has delivered a positive return. The best April on record is +11.8% in 2016; the seasonal pattern reflects Saudi Arabia's fiscal calendar alignment with Q1 corporate earnings releases and Aramco dividend flows.

The nuance in 2026 is that KSA's April seasonal tailwind operates against a meaningful macro headwind: the ceasefire has pushed Brent crude below $95, directly reducing Aramco's upstream revenue per barrel. KSA was the only country ETF with a negative return on April 8 (-0.03%), reflecting this tension. The 80% win rate and +4.14% average are the strongest in the table — but they were built in environments without a rapid oil price decline. In the current setup, KSA's seasonal tailwind is partially offset by the oil shock reversal.

3. Brazil (EWZ) — 20-Year Record, Commodity Alignmen

t

The iShares MSCI Brazil ETF (EWZ) averages +3.36% in April with a 70% win rate across 20 years of data — one of the most statistically robust seasonal patterns in the universe given the full 20-year sample. The April strength reflects agricultural commodity harvest season: Brazil's soybean, corn and sugar cane harvest peaks in March-April, generating strong export revenue repatriation flows into the real.

Across 20 Aprils, EWZ's best returns include +19.6% in 2009, +17.3% in 2008, +15.4% in 2015 and +12.2% in 2016. Even in difficult macro environments — 2022, 2024 — EWZ showed resilience in April relative to other months. In 2026, Brazil is one of only four country ETFs that was nearly flat during the war period (-0.88% from Feb 27 to Mar 31), making it a neutral-to-positive starting point rather than a war-recovery trade. At 9.82x forward P/E — a 42.6% discount to the MSCI ACWI — the valuation case is also compelling.

4. South Korea (EWY) — April Strength Meets Ceasefire Catalys

t

The iShares MSCI South Korea ETF (EWY) averages +3.21% in April with a 70% win rate across 20 years of data. This makes April EWY's second-strongest calendar month by average return, behind only January. The April seasonal strength reflects Samsung and SK Hynix's fiscal Q1 earnings announcements — which typically occur in late April — and the Korean won's seasonal tendency to strengthen as export revenues are repatriated.

Individual April returns from the cache include some striking outliers: +20.2% in 2009, +10.0% in 2020, +7.2% in 2011, +7.8% in 2008. The fund has been negative in April in six of the last 20 years, with the worst reading at -6.4% in 2022 (the Fed tightening shock). In 2026, the April of +12.04% already recorded in the cache is this year's running return — the ceasefire catalyst is already flowing through.

In 2026 specifically, EWY's April seasonal record is being amplified by the war-recovery trade: the fund fell -18.74% during the war and has already recovered +7.89% on the ceasefire day alone. The remaining war-period gap (-12.3% to full recovery), combined with the intact AI earnings thesis and the 70% April seasonal win rate, makes EWY the most multi-layered April setup in the universe. At 7.08x forward P/E — a 58.6% discount to the MSCI ACWI — valuation provides an additional floor independent of seasonality or ceasefire outcomes.

5. Spain (EWP) — High Win Rate, Low Profil

e

The iShares MSCI Spain ETF (EWP) averages +2.32% in April with a 78.9% win rate across 19 years — the equal-highest win rate among the larger-sample ETFs (tied with EWT and EZA at 78.9%). Spain's April strength reflects the Ibex 35's banking-heavy composition (Santander, BBVA, CaixaBank), which benefits from European dividend season flows, and the energy-importer tailwind that the Iran ceasefire directly provides.

EWP is one of the least-discussed country ETFs on global platforms — but its April seasonal consistency (15 positive Aprils out of 19) is among the strongest in the European country ETF universe. At 12.48x forward P/E — a 27.1% discount to the MSCI ACWI — it offers value alongside the seasonal tailwind.

6. Taiwan (EWT) and South Africa (EZA) — Equal Win Rate, Different Storie

s

Both the iShares MSCI Taiwan ETF (EWT) and the iShares MSCI South Africa ETF (EZA) share a 78.9% April win rate with a +1.94% average return across 19 years.

EWT in 2026 carries an additional catalyst: Taiwan's semiconductor companies (TSMC represents approximately 25% of EWT's weight) are direct AI infrastructure beneficiaries whose Q1 earnings reporting cycle begins in April. The ceasefire removes the energy import cost headwind that was pressuring TSMC's fab operating costs through the war period.

EZA in 2026 has the more dramatic recovery story. Having fallen -16.91% during the war — its worst month since March 2020 — EZA recovered +6.49% on the ceasefire day but still carries an -11.4% gap to full war-period recovery. The 78.9% April win rate, combined with the triple-recovery mechanism (energy, precious metals, rand), makes EZA an asymmetric seasonal play in the current environment. At 8.84x forward P/E — a 48.4% discount to the MSCI ACWI — the valuation case reinforces the seasonal case.

The Macro Context: Seasonality + Ceasefire Alignmen

t

The April 2026 setup is analytically unusual in that three independent positive signals are converging simultaneously. First, April is statistically the strongest or second-strongest month for the majority of country ETFs in the universe. Second, the Iran ceasefire has removed the dominant negative macro driver of Q1 2026. Third, the Fed April meeting is priced at 98.45% no change — the rate hike fear that drove the worst quarter since 2022 has been priced out for the near term.

The primary risk to the seasonal thesis remains unchanged: Hormuz normalisation. Prediction markets price only a 32% probability of Hormuz returning to normal by April 30, per Polymarket data as of April 8. A ceasefire collapse would reverse the ceasefire-day gains with equivalent velocity — though the underlying seasonal pattern would persist regardless of the geopolitical outcome.

Frequently Asked Question

s

Which country ETF has the best April seasonality record?

Based on 20-year SeasonalityCache data from CountryETFTracker, the Global X MSCI Greece ETF (GREK) has the highest April average return at +4.88% with a 78.6% win rate (14 years). The iShares MSCI Saudi Arabia ETF (KSA) has the highest win rate at 80% with +4.14% average return (10 years). For longer datasets, the iShares MSCI Brazil ETF (EWZ) leads with +3.36% average and 70% win rate across 20 years.

Does April seasonality always work for country ETFs?

No. Seasonal win rates represent historical frequencies, not guarantees. A 70% win rate means the fund was negative in April in 30% of historical years. In 2026, the primary risk is a ceasefire collapse, which would override the seasonal tailwind as the oil shock did in March.

Why is Japan (EWJ) ranked lower despite being a strong April market?

EWJ's April average return is +1.04% with a 60% win rate — lower than the top-ranked ETFs because the fiscal-year-opening tailwind is partly offset by yen movements and global risk appetite sensitivity. EWJ is a strong April candidate but ranks behind GREK, EWZ, EWY and EWP on both the average return and win rate metrics from the actual seasonality data.

What is the difference between EWP and EWG in April seasonality?

Spain (EWP) averages +2.32% in April with a 78.9% win rate (19 years). Germany (EWG) averages +2.34% in April but with a lower 57.9% win rate (19 years) — meaning EWG's higher average is driven by a few large positive outliers, whereas EWP's lower average is delivered more consistently. For investors prioritising consistency over magnitude, EWP's 78.9% win rate makes it the more reliable European April play.
