Q1
What cultural values influence customer behavior?
Group loyalty and respect for hierarchy in both. Singapore adds a hunger for value and proof; Vietnam buys on family trust and a product's origin.
Singapore
Kiasu deal-seeking, four communities’ festivals, and trust in official proof.
Vietnam
Family decisions, word of mouth, gifting at Tết, and faith in Japanese and US brands.
For business buyers: senior sign-off and relationships drive decisions in both. Singapore expects documented evidence and a clear process; Vietnam expects introductions, repeated face-to-face contact and patience on timelines.

How each culture is wired
Both are collective and hierarchical. They differ most on the need for rules.
- Power distanceacceptance of hierarchy
- Singapore: 74High: respect for authority and seniority
- Vietnam: 70High: everyone has a place
- Individualismme vs. we, revised 2023
- Singapore: CollectiveFamily and group come first
- Vietnam: CollectiveLong-term loyalty to the group
- Uncertainty avoidanceneed for rules
- Singapore: 8Very low: pragmatic, but follows rules that exist
- Vietnam: 30Low: practice counts more than principle
What that means at the till
Group values show up differently: Singapore's shoppers chase value and certainty; Vietnam's follow family, friends and trusted origins.

Singapore
- Many cultures, one market: citizens are 75.5% Chinese, 15.1% Malay and 7.6% Indian. Campaigns follow Chinese New Year, Hari Raya and Deepavali, and halal certification matters for food.
- Kiasu (“fear of losing out”): shoppers compare, hunt deals and join loyalty schemes. Limited-time offers and clear guarantees work.
- Respect for authority: official endorsements, awards and expert proof carry weight; exaggerated claims backfire.

Vietnam
- Family decides: big purchases are group decisions, and word of mouth from friends and family is the most trusted channel.
- Face and gifting: Tết and other festivals drive gift buying, where brand and packaging signal respect.
- Origin is a quality signal: nearly 60% hold a very positive view of Japanese products and 42% of American ones, but only 15% of Chinese ones. Younger buyers trust Vietnamese brands more than their parents do.
What it means for a marketer

Singapore
Prove the value, then localize for each community.

Vietnam
Earn the family’s trust, and say where it’s from.
