It would be necessary to have the list of past predictions from UBS for this figure to have any meaning. Otherwise you fall into the trap of "Economists successfully predicted 10 of the last 4 recessions".
So 52%, not 93%, and I can't find a link to where UBS published this information.
But here are some other recent figures from UBS (or at least attributed to them):
2022-05-05: 0% https://www.ubs.com/global/en/investment-bank/insights-and-d...
2022-06-21: 40% https://finance.yahoo.com/news/odds-hard-landing-u-economy-2...
2022-08-30: 60% https://www.investing.com/news/stock-market-news/ubs-raises-...
2023-07-19: Goldman Sachs says 20% https://www.goldmansachs.com/insights/articles/the-probabili...
2024-08-27: 25% https://www.reuters.com/markets/us/ubs-wealth-management-rai...
I think the number is largely useless, and this article is even moreso.
Edit: there's one open bet on a US recession in 2025 on Kalshi that's gone down to only a 5% chance. Sort of fascinating how it's exact opposite of what TFA is saying. I'd link but not sure if that's kosher.
I guess it's kinda like betting on who will win an election vs. betting on a candidate conceding an election. The odds aren't necessarily the same, even though they're (on paper) closely related events.
