The Bond Vigilantes World Cup Model

For the 2026 World Cup, the Bond Vigilantes team have designed a predictor model, combining economic fundamentals with official FIFA rankings to help forecast how the World Cup will play out.

Each day we will look at some of the most interesting games, and provide not only a predicted outcome from our model, but also some interesting (non-football-related) talking points from our usual bloggers, plus a few guests across the broader fixed income team.

Report back each day to see the latest predictions and country write-ups from our bond specialists.

The model

For those here for the model, below we have shared the formulae and rationale for the output.

The model is a 50/50 blend between a normalised FIFA points score, and a normalised economic metric score. Depending on the relative strength of the scores, an expected goals number is produced to predict the result of the game.

After several million runs of code, we have tweaked our economic model to produce the following output, based on population, real GDP growth, inflation, unemployment, policy rates, and finally, government debt-to-GDP ratios:

Econ Model:  (LOG10(Pop)-6)^1.2 × (1+GDP/8) × 1/(1+Infl/8) × (1-Unemp) × 1/(1+Rate/20) × 1/(0.8+Debt÷GDP/5)

The rationale for the inclusion of the above metrics follows.

• Population is the bedrock of the model. Football is a numbers game: the more people you have, the more likely it is that a few of them can do something with a ball. We use a log scale because going from 5 million to 50 million matters enormously, but going from 500 million to 5 billion does not help you find a better left back.
• GDP growth captures momentum. A growing economy tends to mean investment in infrastructure, and with that comes football academies.
• Inflation is the instability penalty: when the price of a matchday pie is doubling every year, it is hard to maintain the kind of institutional stability that produces world class players.
• Unemployment is a proxy for development. Lower unemployment signals a functioning economy, disposable income for grassroots football, and parents who can afford to let their children train rather than study to work.
• The policy rate is a good signal for macroeconomic credibility. Countries with rates below 5% tend to be places where institutions work.
• Government debt to GDP is deliberately the weakest factor. Japan for example, at 255%, would otherwise be pushed too far down the rankings. We penalise heavy debt gently, like a yellow card rather than a red.
• Finally, we blend the economic score 50/50 with the FIFA world rankings (the official ones from 1 April) to stop the model producing results that are funny for thirty seconds and then become a credibility problem. Argentina finishing behind Curacao on pure economics is entertaining, but the rankings anchor reminds us that Scaloni’s squad is probably still quite good despite the peso.

Finally, we’ve sprinkled in a little bit of randomness as there is no shortage of variance in sporting events!

First up is the opening game, Mexico vs South Africa.

Carlos Carranza, Emerging Market Debt Portfolio Manager says:

Well…if South Africa manages to play the same way it has managed its fiscal dynamics, then Mexico should brace for impact, because that staggering narrowing in the deficit has been a goleada all along.

But make no mistake, Mexico is still a “futbol IG” and they are going to put up a great battle. El tricolor has very strong institutions: like Banxico or Guillermo Ochoa. Neither of them will ever drop the ball. Literally.

 Both in politics and futbol….South Africa doesn’t do superstars. They’re more like a well-diversified portfolio, resilient and surprisingly effective when combined. Don’t forget the ANC lost its majority in 2024 and then entered into the ultimate football-finance strategy: GNU = “Goals Need Unity!!”

Our model predicts this one to come out as 2-0 to the hosts, though I think there is scope for a 1-1 here. Mexico will attack…but SA will tighten the spreads. I am inflating my expectations…because it’s not just a match…it’s an EM rally.

Following that, it’s South Korea vs Czechia.

Eva Sun-Wai, Global Macro Portfolio Manager says:

South Korea arrives at the World Cup with a profile familiar to investors: strong fundamentals, plenty of volatility and absolutely no consensus on the right narrative. Equity markets have swung between AI euphoria and sharp sell-offs, higher oil prices have nudged inflation forecasts higher, and the KRW continues to command more attention than most central banks would prefer. Yet semiconductor exports are growing at 169% YoY, total exports have recorded their strongest growth since 1984, and the Bank of Korea has upgraded its 2026 growth forecast to 2.6% from 2.0%.

The result is a reaction function that would give most football managers a headache. Inflation says one thing, growth says another, the KRW occasionally demands an emergency intervention, and then the AI supply chain turns up and changes the scoreline. It is perhaps telling that the BOK’s policy discussions increasingly span inflation, growth, financial stability and the exchange rate simultaneously.

Meanwhile, S Korea finds itself in familiar territory: good enough to compete for qualification, but still trying to prove it belongs among the elite. Korea Treasury Bonds are entering the FTSE World Government Bond Index, with estimates of roughly USD52bn of inflows, while the longer-running pursuit of developed-market status continues. Much like Korea’s famous 2002 run to the semi-finals, everyone agrees it was an impressive achievement; the debate is whether it was a stepping stone to something bigger or simply a very memorable tournament.

Eldar Vakhitov, Emerging Markets Sovereign Analyst with our commentary for Czechia.

Czechia is set to appear in the World Cup for only the second time as an independent nation, following the breakup of Czechoslovakia in 1992. Their previous appearance was in 2006, when the tournament was hosted by neighbouring Germany, their main trading partner. Even then, they failed to progress to the knockout stage. Meanwhile, Czechia’s GDP per capita has climbed to 71% of the euro area average in 2026, up from just 45% in 2006. Whether this impressive performance can be mirrored in a stronger showing at this World Cup remains to be seen. This improvement is one of the key reasons the IMF now classifies Czechia – along with group rival South Korea – as an advanced economy. The question is whether much better macroeconomic and institutional foundations will help them outperform the “true” emerging market countries in their group, Mexico and South Africa.

Czechia has long maintained prudent fiscal policies and keeps government debt relatively low, with almost all of it denominated in its own currency – this significantly limits its reliance on foreign financing. On the pitch, however, the national team will depend heavily on its star players based in foreign clubs to make an impact. Meanwhile, the Czech central bank is considered one of the most disciplined across emerging markets, fiercely guarding its inflation targeting credibility. Those same qualities – discipline, consistency, and cautious approach – may be exactly what the football team needs if it hopes to reach the knockout stage this time.

Let’s see how The Bond Vigilantes World Cup Model fares in the first two games.
