TL;DR: Worship of the God of Wealth (Thần Tài) has Chinese cultural roots and entered Vietnam centuries ago, but it only surged when the economy shifted to a market mechanism. Đinh Hồng Hải (2014) explains the boom through the psychology of attributing the luck of getting rich to invisible support, while Nguyễn Hữu Thụ (2019) shows that most devotees in wealth-seeking religious activities are traders. Existing research describes a correlation between the market economy and belief; there is no quantitative data on shopping behaviour on the God of Wealth Day.
Where does Thần Tài come from, and why did the cult surge in a market economy?
Worship of the God of Wealth (Thần Tài) originates in Chinese culture and entered Vietnam centuries ago, but it only truly surged when the economy shifted to a market mechanism. According to Đinh Hồng Hải, in contemporary Vietnam some people grew rich quickly through unexpected opportunities, attributed that outcome to unseen aid, and went looking for the deity that had helped them, which made demand for Thần Tài worship explode. Nguyễn Hữu Thụ (2019) studied Mother Goddess worship in the Northern Delta and found that after the 16th century this belief gradually shifted from reflecting an agricultural economy to reflecting a commodity economy, with devotees largely being traders.
Two layers must be distinguished. The first is the origin and localisation of the Thần Tài figure in Vietnamese culture, covered in The Origins of the Worship of Thần Tài - Ông Địa in Vietnamese Culture. The second, and the focus here, is the relationship between that cult and market economic life: why a household cult once kept quietly in each home has become a large social phenomenon on occasions such as the God of Wealth Day.
Why is Thần Tài worship so tightly bound to small traders?
Small traders are the group most clearly attached to Thần Tài worship, and this follows from the nature of their work. Đinh Hồng Hải argues that when business results depend heavily on factors beyond the trader's control, people tend to attribute that luck to an invisible force able to assist them. For a small trading household with little capital, no market analysis unit, and no capacity to withstand price or demand shocks, the degree of uncertainty in business outcomes is far higher than for a large firm. Technique and experience control only part of the result; the rest people call luck. Thần Tài worship sits exactly in that gap.
Nguyễn Hữu Thụ (2019) cites the case of Bà Chúa Kho temple in Cổ Mễ, Từ Sơn, Bắc Ninh, where people come at the start of the year as borrowers and at the end of the year as repayers, and notes that those who come to the Lady as borrowers are mostly of average, even relatively difficult, means. Belief in a real economic turnaround is strong enough that in folk imagination the Lady turned from a keeper of the court's granary into a banker with the financial norms of modern society. This is how people tell and believe the story, not a description of a historical figure.
How did the commodity economy bring gods of fortune into trading life?
Nguyễn Hữu Thụ (2019) shows that if before the 16th century Mother Goddess worship was tied largely to an agricultural economy, after the 16th century it gradually reflected a commodity economy with the rising role of merchants, expressed through the figures of Saint Mother Lieu Hanh and the Three Palace Holy Mothers. The author records a series of Mother Goddess temples and palaces springing up along the North-South trade route, with most devotees being traders. In religious practice they found spiritual support to feel more confident in economic activity.
Philip Taylor in Goddess on the Rise (2004) surveys pilgrimage and popular religion in Vietnam and records traders approaching goddesses to ask for fortune. This is one of the anthropological works most cited on the relationship between commerce and goddess worship in Vietnam.
One notable minority hypothesis: Cao Thế Trình (2020) raises the question of whether Mother Goddess worship of the Three Palaces may have begun as a cult of a goddess of fortune among small traders. The author also stresses that Three Palace Mother Goddess worship is mainly the belief of the trading class, so when the country operates under a market mechanism it erupted strongly in both places of worship and mediumship rituals. It must be said clearly: this is a hypothesis, not yet widely repeated or verified by researchers, and the author himself raises the question of the fragile boundary between belief and the commercialisation of spiritual activity.

Is the crowded God of Wealth Day something new?
The crowds on the God of Wealth Day are the surface expression of a deeper process: wealth-seeking belief moving from private household practice into public space and taking on a more communal character as the market economy expands. Đinh Hồng Hải (2014) describes Thần Tài worship as having long existed in Vietnamese culture, but its explosive growth today is a new social phenomenon. The author also notes that both rich and poor who want to seek fortune quickly bring Thần Tài statues home to worship.
Two questions that are often merged must be separated. First: why do people worship Thần Tài? The answer lies in the psychology of attributing the luck of business to an invisible force, as Đinh Hồng Hải argues. Second: why does that cult concentrate in large numbers on one particular day of the year? Answering this requires data on shopping behaviour, on how votive paper shops organise sales, and on mass media on those days. Within the sources used for this article there is no quantitative data on shopping behaviour on the God of Wealth Day, so the article draws no conclusion about the scale or direct causes of the crowds on that day.

Does belief alone improve business results?
Religious and spiritual belief can affect behaviour, and behaviour affects outcomes, but that mechanism is not the same as a deity directly granting fortune. Đinh Hồng Hải (2014) observes that in religious practice devotees find spiritual support to feel confident in economic activity. This describes the mental state of participants, not the efficacy of ritual. Nguyễn Hữu Thụ (2019) also notes that the community where a temple or palace stands, along with the ritual groups centred on mediums, is strongly affected in economic life. That effect is the social and economic effect of religious practice, not evidence that prayers are answered.
In other words, the question is not whether the deity is efficacious, but what participants believe, what they do, and what traces that leaves in their economic life and that of the community. This framing keeps a distance between scientific description and insider belief while respecting practitioners.
Nhật Nguyệt's suggestion:
If you are trying to decide whether to set up a Thần Tài altar, it helps to separate two things: worship as a spiritual need and business as an activity requiring technique. The studies cited here show that belief can help traders feel more confident, and that confidence can shift behaviour in a more positive direction. But no source in this article proves that worshipping Thần Tài increases profit. If you choose to worship, treat it as a way of arranging your living space and keeping your spirits up, alongside learning the trade, managing cash flow and understanding the market.
For those observing the crowds on the God of Wealth Day, what is worth noting is not judging others' beliefs, but that the phenomenon reflects an economy with many small operators facing high uncertainty and seeking different ways to cope with it. Understanding that also explains why this cult has not declined as material life has improved.
