In order for a Brazilian market participant to track the S&P 500^® through equity index futures, they must first convert Brazilian reais to U.S. dollars and then use U.S. dollars to enter a position in equity futures. This transaction involves two sources of risk: equity risk and currency exchange risk.

To address the currency exchange risk faced by Brazilian market participants, S&P Dow Jones Indices launched the S&P 500 Futures Quanto USD-BRL Currency Adjusted Index (S&P 500 Futures Quanto USD-BRL Index) on Nov. 1, 2024. The index provides a measurement of U.S. equities futures for Brazilian market participants. It does this by measuring the performance of the nearest-maturing quarterly E-mini S&P 500 Futures contract trading on the B3 exchange, following a quarterly roll¹ schedule.² Additionally, it integrates a quanto currency adjustment, which settles daily returns in BRL rather than the currency of denomination. This currency adjustment seeks to mitigate currency exchange volatility.

To illustrate the currency risk component, we compared the performance and risk characteristics of the S&P 500 Futures Quanto USD-BRL Index against the S&P 500 Futures Index (B3) (USD), which follows the same futures methodology but without the quanto currency adjustment. Historically, the S&P 500 Futures Quanto USD-BRL Index offered similar cumulative and periodic performance when compared with the unadjusted index (see Exhibit 1).

Moreover, the S&P 500 Futures Index (B3) (USD) had a historically high correlation and a similar risk profile when compared to the underlying index (see Exhibit 2). Since inception, the S&P 500 Futures Quanto USD-BRL Index closely tracked the unadjusted index, having an annualized tracking error of 0.2%.

Furthermore, the quanto adjustment led to outperformance on a total return basis as well. From Jan. 31, 2015, to Feb. 28, 2025, the S&P 500 Futures Quanto USD-BRL Currency Adjusted Index has delivered a cumulative excess total return of 350% relative to the unadjusted index.

This is because futures total return indices incorporate excess return and the interest earned on hypothetical fully collateralized contract positions. Exhibit 3 demonstrates the substantial cumulative impact when incorporating the daily CETIP interbank overnight rate on a fully collateralized³ position to calculate total returns. Historically, the S&P 500 Futures Quanto USD-BRL Currency Adjusted Index earned strong returns on top of the equity index futures return due to an environment where Brazil’s interest rates remain relatively high.

In summary, the S&P 500 Futures Quanto USD-BRL Currency Adjusted Index measures U.S. large-cap equities, and has historically mitigated currency exchange risk, allowing market participants to avoid the impact of BRL/USD fluctuations. Additionally, it has provided additional outperformance due to Brazil’s interest rate environment.

¹ Roll refers to the process of closing a position in a futures contract that is nearing its expiration and simultaneously opening a new position in a futures contract with a later expiration date.

² The roll frequency schedule occurs over a three-day roll period quarterly in March, June, September and December, effective after the close of the third, fourth and fifth business day preceding the last trading date of the futures contract. The index distributes the weights equally each day over a three-day roll period. For more details, please refer to the S&P Futures Indices Methodology.

³ Collateralized refers to a financial arrangement where an asset is pledged as security for a financial obligation, serving as a guarantee.
