In a wavering global context like the current one, different sectors of the economy suffer unexpected consequences.
This scenario also has an impact on people, which is why several are making a preventive financial decision.
Within the framework of this reality, he issued his opinion Luis Garviaa renowned economist, who provided a advice on how to act in the face of the disconcerting situation.
How much cash is recommended to have? The advice of expert Luis Garvía
The economic uncertainty derived from the international geopolitical situation is impacting different sectors, including energy, industrialthat of transport and food.
In addition, of course, it affects the markets and finances, and that is why some citizens are once again looking towards the cash as a measure of economic security. This is certified by several studies.

In general, the Global Payments Report He stressed that, In contexts of economic disruption or uncertainty, the demand for cash tends to increase between 8% and 15%reinforcing its role as a security asset and reserve of value. This happened, for example, during the time the pandemic lasted Covid 19.
Specifically, the European Central Bank stated that, during 2025, demand for banknotes saw strong growth despite the digitalization of payments.
Regarding this situation, he referred Luis Garvía, economics expertinterviewed on the Spanish radio program «Herrera en COPE».
In particular, Garvía insisted on the importance of being prepared for a potential downfall of digital banking systems.
For this, he maintained, people have to save enough cash to cover themselves for 15 days. «It must be the equivalent of two weeks of basic expenses«he explained.
This reserve, the economist explained, would be enough to «cover» the expenses in supermarket, fuel or public transport and medicines. In this way, those affected could guarantee their ability to meet immediate needs until digital systems work again.

Garvía’s recommendation coincides with that of other financial institutions. The European Central Bank suggested having between 70 and 100 euros (approximately between 80 and 115 dollars) per person, while countries like Sweden advise keeping a similar amount in bills of different values.
Furthermore, it is worth paying attention since, in the past, the economist anticipated events like those that are currently happening.
Luis Garvía’s accurate predictions: «A possible conflict in Iran»
Luis Garvia He studied Higher Industrial Engineering at the Comillas Pontifical University of Madrid, in addition to degrees in Business Administration and Management and Law at the National University of Distance Education (UNED).
As if the above were not enough, he also completed a master’s degree in Administration at the University of Navarra (IESE) and a PhD in Finance at the Comillas Pontifical University.
At the latter institution, since 2009, he has been a professor in the areas of accounting and finance, financial mathematics, ethics and strategy, among other disciplines. Also, since 2020, he has directed the university master’s degree in Financial Risk Management.
In addition to dozens of publications and conferences, Garvía is known for predicting events that then actually occur.
In December 2025, for example, it rose video to Instagram, in which he anticipated that 2026 would be «a year of unprecedented geopolitical tensions.
Specifically, he listed a series of conflicts that could happen, including the war in iranand the consequences that this would bring.
«A possible conflict between Iran and the rest of the monarchies of the (Persian) Gulf would put global crude oil trade in check. Between 25 and 30% of liquefied natural gas and between 20 and 25% of all world crude oil circulate through the Strait of Hormuz. A conflict in this geographical area would cause us to once again see prices per barrel of crude oil above $150,» he explained.
As is public knowledge, in February of this year a war began that has Iran as a participant and headquarters of combat, and that also involves the United States and Israel, so Garvía’s prediction was correct.
What’s more: the Strait of Hormuz was blocked and the price of a barrel of oil increased, to the point that, at the beginning of April, Brent reached 144 dollars, very close to the lower limit (150) predicted by the economist.
