Vietnam PMI May 2026: Stockpiling efforts contribute to renewed rise in new orders in May

New orders and purchasing activity return to growth.
Marked rise in production.
Input cost inflation accelerates again.

Cimigo Vietnam market research has collected the Vietnam PMI – manufacturing purchasing managers index since 2013. S&P Global compiles the Vietnam PMI S&P Global from responses to monthly questionnaires sent to purchasing managers in a panel of around 400 manufacturers.

Vietnam PMI findings

A return to growth of new orders in May helped the Vietnamese manufacturing sector to expand midway through the second quarter of 2026. At least part of the increase was due to safety stock building at customers due to the war in the Middle East causing steep price rises and supply-chain delays.

Similarly, stockpiling efforts also encouraged manufacturers to raise their own purchasing activity. Despite the improvements in new orders and output, firms continued to scale back their workforce numbers amid evidence of continued spare capacity.

The S&P Global Vietnam Manufacturing Purchasing Managers’ Index™ (PMI®) rose to 52.8 in May, up from 50.5 in April and reaching its highest since February, just before the outbreak of war in the Middle East. The solid overall improvement in business conditions was the eleventh in as many months.

After having fallen modestly in April, new orders returned to growth in May, increasing markedly and to the largest degree in three months. To some extent, the rise in new business reflected safety stock building among customers amid worries of the effects of a prolonged conflict in the Middle East.

A renewed increase in new export orders was also recorded, ending a two-month sequence of decline. Here though, the pace of expansion was only marginal, as high transportation costs and logistics issues limited international demand.

Renewed growth of new orders was matched by a marked expansion of manufacturing production in May. Output rose for the thirteenth successive month, and at the fastest pace since February.

Stockpiling efforts were also evident among manufacturers as purchasing activity increased for the first time in three months, and at a solid pace. The rate of input cost inflation continued to accelerate midway through the second quarter, quickening for the fourth consecutive month to the fastest since April 2011. Fuel, oil and transportation were the main drivers of higher input costs, according to respondents.

Selling price inflation also remained elevated and was among the sharpest in the past 15 years, despite easing slightly from that seen in April. Higher costs for fuel and shipping, plus issues with logistics, caused a further lengthening of suppliers’ delivery times in May.

Vietnam PMI May Trend

The latest deterioration in vendor performance was less pronounced than in the previous survey period, however. A further lengthening of lead times meant that stocks of purchases continued to fall, despite an expansion in purchasing activity. Moreover, the rate of depletion in preproduction inventories was the fastest in just under a year. Stocks of finished goods were also down, albeit to a smaller degree than in April.

Despite a renewed rise in new orders in May, recent demand weakness meant that firms still had sufficient capacity to handle incoming business and work through backlogs. As a result, outstanding business decreased for the second month running.

Evidence of spare capacity was a factor behind a further reduction in manufacturing employment, which decreased for the third time in as many months. The rate of job shedding was only marginal, however.

Confidence in the year-ahead outlook for production improved to a three-month high in May amid hopes for an increase in new orders and business expansion plans. Sentiment remained relatively muted, however, reflecting concerns about the ongoing impact of the war in the Middle East.

The S&P Global Vietnam Manufacturing PMI® is compiled by S&P Global from responses to monthly questionnaires sent to purchasing managers in a panel of around 400 manufacturers. The panel is stratified by detailed sector and company workforce size, based on contributions to GDP.

Survey responses are collected by Cimigo Vietnam in the second half of each month and indicate the direction of change compared to the previous month. A diffusion index is calculated for each survey variable. The index is the sum of the percentage of ‘higher’ responses and half the percentage of ‘unchanged’ responses.

The indices vary between 0 and 100, with a reading above 50 indicating an overall increase compared to the previous month, and below 50 an overall decrease. The indices are then seasonally adjusted.

Đoàn Ngọc Huy (Johnny Doan), CMO & Market Research Expert -

As a Marketing Director and Market Research Expert Advisor across international markets, I have collaborated with numerous market research agencies, both global and local, that operate with a high level of professionalism and effectiveness. Cimigo is among the most outstanding. The Cimigo team demonstrates exceptional professionalism, strong commitment, and operational excellence. From research design and fieldwork execution to insight analysis, all stages are conducted rigorously, delivered on schedule, and closely aligned with business objectives. This is a highly capable team that I would confidently recommend to my partners and stakeholders.

Lisa Nguyen - Vietnam Marketing Lead

It's been a great experience working with the Cimigo team. The team was highly professional, proactive, and supportive, handling many complicated requests from us in such a limited time. I appreciate our cooperation and will definitely recommend Cimigo for upcoming similar projects.

Mark Ratcliff - Managing Director

The team at Cimigo are my favourite researchers in South East Asia. They’ve proved adept at tackling the most private and complex personal issues at qualitative research level, not flinching when the client endlessly chopped and changed fieldwork timing, or ramped up the workload without warning. They have recruited the most extraordinarily niche consumers without pause or complaint. Their patience with clients and their flexibility and hard work that went above and beyond what was initially asked of them on two projects relating to sexual behaviour means there is now no other research company we would choose to work with in that part of Asia. The fact they also pulled off a third project for us so well, on men’s relationship with beer and beer advertising, shows they have breadth of expertise— we still quote from the report they produced.

If only all our research partners were as switched on and easy to work with.

Kevin McQuillan - Chief Marketing Officer

Starting with customer understanding is critical to how we manage our business and develop for the future. Cimigo undertook a challenging brief – across multiple cities and segments nationwide – and again came up with a high-quality solution with timely implementation and considered insights, allowing us to successfully orientate our plans and strategy around consumers in Vietnam.

Sam Houston - Chief Executive Officer

Cimigo’s responsiveness and insights exceeded expectations; I highly recommend their market research services. Atlas tasked Cimigo with analysing and prioritising opportunities across four international markets. Cimigo mapped the Architecture, Construction, and Engineering landscape in each market, identified and prioritised opportunities, derived a dollar value by opportunity and provided details on target prospects and projects. This data-driven approach has enabled Atlas to develop services and focus resources on where we can bring the most value in our international markets.

Minh Thu - Consumer Market Insights Manager

Working with Cimigo has been incredibly rewarding. Their exceptional service and unwavering commitment to excellence have been truly impressive. Together, we've successfully completed projects ranging from fabric care like detergents and fabric softener to home essentials like floor cleaner and dishwashing liquid in both urban and rural settings, showcasing Cimigo's versatility and dedication to reaching diverse markets. Thanks to Cimigo's dedication and expertise, we secured a major project with our client last year. I'm grateful for our partnership and excited for future collaborations.

Travis Mitchell - Executive Director

Cimigo has been an excellent partner for AmCham. They provided insightful feedback during the planning phase of our project and offered suggestions to ensure that we met our goals. Their analysis was comprehensive, thoughtful, and accurate, and I appreciated their customer service skills – I always felt that Cimigo had our best interests at heart. I’m very much looking forward to working with Cimigo again in the near future!

Malcolm Farmer - Managing Director

I have never seen or had support for our business like we have received from Cimigo Vietnam. The depth & understanding of our business shows how well you have studied both Jardines Distribution Inc. and Koppers Performance Chemicals. We, (JDI & KPC), really appreciate the efforts the whole Cimigo team have put into your research. The help to connect potential distributors for both our Industrial and retail products are absolutely on point. I will have no hesitation in recommending Cimigo Vietnam to any company wanting to venture into the Vietnam market.

With extensive knowledge of Vietnamese consumers, Cimigo keeps bringing value to our company. We look forward to working with them in the future.

Joe Nelson - New Zealand Consulate General

The research provided by Cimigo provided our clients with very specific insights into consumer behaviour in Viet Nam. What I liked was the way Cimigo interpreted these insights to develop a clear call to action for our clients, which they are responding to with confidence.

Steve Kretschmer - Executive Director

Cimigo conducted a large, nationally representative demand forecasting study in Vietnam for us, including a discreet choice component, to assess demand for potential new male contraceptives in development to support funding decisions by The Bill & Melinda Gates Foundation. The research was additionally complex by linking interviews with men and separate interviews with their female partners. The Cimigo team was professional, knowledgeable and adaptive through the process of understanding our needs and collaborating to find solutions that would work, resulting in a very successful study.

York Spencer - Global Marketing Director

I've had the pleasure to work with Richard and Cimigo over many years and across multiple markets. Cimigo was a key partner in our business decision making process including market entry strategy, brand positioning development, shopper insights, brand equity tracking, and consumer need state segmentation development. The Cimigo team are local market experts who understand consumer culture like no other. I would highly recommend them.

Mai Trang - Brand Manager of Romano

Cimigo is the research agency that I appreciate for their expertise and customer service. Cimigo understand well the business context for each of project hence they can design the research to best fit with the objectives. The optimization on methodologies, sample size and questionnaire bring the value to the projects I have worked with them. Cimigo can go beyond data and give me valuable insights for each of research projects based on their knowledge and experience with the industry. All of these support me well to navigate the brand strategy in short term and long term.

Hanh Dang - Product Marketing Manager

We partnered with Cimigo on assessing TET campaign launch focusing on improving booking through our platform. Cimigo, provided its customized campaign evaluation technique based on Cimigo Online Communities that fully meets our requirement in terms of type of respondents and expected timelines. The report provided insightful findings with benchmarks to identify the next course of action for launching the campaign. We will recommend Cimigo team and its Online communities for its quality reporting and scale of coverage.

Max Lee - Project Manager

Cido have worked with Cimigo in Vietnam for more than 10 years. All our projects, both qualitative and quantitative, have been delivered in a timely manner with a high standard of quality throughout. Cimigo’s client service team has provided great support over the years which has ensured smooth project execution and helped us to deliver work on time and exceed our client’s expectations.

Chris Elkin - Founder

I have partnered with Cimigo over the past 15 years. Most recently Cimigo engaged us to collaborate on an unusually tough new product development project, which was akin to selling ice to Eskimos. Cimigo bought alive the consumer, her shopping journey, her cooking rituals and potential brand promises. Cimigo inspired our creative team to build alternate brand propositions and accompanying package designs. Cimigo then went back to consumers to evaluate, iterate and optimise these in focus groups. The Doodle team were able to observe this process and subtly adjust the expression of the brand between focus groups. The result of this great collaboration was a winning brand proposition and packaging design that hit consumer needs head on whilst appealing to their hearts.

Ronald Reagan - Deputy Group Head After Sales & CS Operation

We have worked together with Cimigo many times. The findings from Cimigo are factual, accurate & reliable. They deliver value from the voice of our customer so we can easily determine the next step. Working with Cimigo feels like not only building a partnership but a sense of family. Very amazing to work with Cimigo, they always go beyond our expectations.

Chad Ovel - Partner

Cimigo digs deep to understand the key issues we need to address. Then, they quickly customize a highly suitable research approach to provide us the insights we need to achieve our breakthrough business targets. From tough questions to aha answers in just a few easy conversations!

Private English Language Schools - Chief Executive Officer

Our relationship with Cimigo goes back many years. We engaged Cimigo to provide an independent view on what our customers and potential customers think of our company. The insights from Cimigo were very helpful for us to better understand the Vietnam market and also in developing our brand manifesto.

Rick Reid - Creative Director

As a creative director I have used the services of Cimigo for the past 15 years when developing communications, so I know their style, innovations and resources well. Most recently we tested copy for print, out of home and digital communications to put an Australian colloquialism into a Vietnamese context. A job and budget so small I felt it was highly likely to fall through the cracks. I was astounded at their incredible response. From their advice and style of how we should present the stimulus material, to their cross-reference manoeuvres used in the testing. Their over-delivering response, was to an embarrassing level. We walked away with a clear winner and could present back to our client with confidence and clarity. Cimigo made us look great. Plus they even threw in a few extra insights on the awareness and perception of the product in Vietnam.

Dr. Jean-Marcel Guillon - Chief Executive Officer

Cimigo have built and managed both our employee and customer experience programme since 2012. We have a complex suite of services with in-patient, out-patient, surgical, diagnostic, consultative and facilities to account for, all amongst patients who are naturally sensitive regarding their privacy and experience. Yet Cimigo have designed a system to measure customer experience across multiple languages and cultures and direct us in improving this experience. Our net promoter score (NPS) has grown as a direct result of changes implemented based on this direction and continuously listening to patient feedback. The NPS growth correlates directly to new patient numbers and improved profitability, as happier customers drives our business growth.

Matt Thwaites - Commercial Director

Cimigo designed a customer experience programme for Coats that reached into Vietnamese, Chinese and Korean customers across various levels of seniority. Cimigo instilled the importance of the voice of the customer within our executive committee. This led to fundamental changes in our structure, services and speed to market. Significant investments were made behind these improvement programmes, for example in reducing delivery times and in managing specialised custom orders, which in turn have led to improved revenue streams and higher margin sales.

Aashish Kapoor - Head of Marketing

Cimigo - The best “Glocal” market research firm in Vietnam with whom we have developed a great partnership since many years. While the quality of research and findings are of top standard, the added advantage being the local insights that Richard and his team are able to provide in helping us make important decisions.

Kelly Vo - Founder & Host

I respect Cimigo not only because of their dedication, meticulousness, and high-quality services but also how much they care about the local community here. I proposed the idea of doing a survey with the digital young generation on the topic of social impact and leadership. I wanted to identify, shape, and develop our content so that could really speak to the heart of the problems and empower young Vietnamese to take action on social impact in Vietnam. The Cimigo team agreed pro-bono to help without hesitation. The research findings are truly helpful in providing us a deeper understanding of our targeted audiences, what they need and are concerned about in life. The results show us how we can help them to achieve their goals and dreams. It is no longer a shot in the dark!

Hamish Glendinning - Business Lead

Cimigo not only delivered an exceptional piece of qualitative research for us, but provided hugely valuable direction when it came to product development and market positioning which we have since implemented. We can’t wait to work with the team again.

Thuy Le - Consumer Insight Manager

Pharmacity started a Brand Health Check with Cimigo in 2020 and we were immediately impressed with their great consultancy and supportive spirit. The study had interesting analysis and insights which helped us efficiently shape the marketing plan and direction moving forward. We are now working with Cimigo on a tracking basis to continuously monitor and foster our brand performance.

Richard Willis - Director

When we were looking to develop one of the worlds the leading economic indicator in Vietnam, the Purchasing Managers’ Index™ (PMI®) Cimigo showed an immediate understanding of our needs and showed their understanding of the Vietnamese market. IHS Markit has now been working with Cimigo since 2013. Every month Cimigo continues to provide high quality data, a representative panel, on time data and great customer service. We look forward to many more years of working together.

Ha Dinh - Project Lead

I have worked with CIMIGO on educational research for over 4 months. This is extremely impressive to me by the way CIMIGO approaches, cooperating and supporting me during the research launched. Specifically, the design for both qualitative and quantitative research are practical and logical with accurate questionnaires and appropriate interviews methodology for different respondents. Moreover, the outcomes of this research helps us to recognize our opportunities in the current English Language Training Market and understand profoundly our customer needs, behaviours and expectations when sending their children to us.

Vo Thi Thuy Ha - Commercial Effectiveness

Working with Cimigo, we can see the dedication, good business sense, and great client service from the Cimigo client service team. Cimigo's team always demonstrates a high standard of client service with high flexibility, trying to offer the most suitable options for clients, although sometimes it is quite a stretch. Cimigo often offers very interesting approaches to solving our research objectives. I appreciate that the team can go the extra mile, trying to find good methodology and insightful findings to answer MSD's business questions.

Louise Knox - Consumer Technical Insights

Just to say a huge thank you for all of the film footage. We are absolutely delighted with it all. The Vox Pops are really interesting and have turned out very well – those ladies were great at talking spontaneously. Cimigo did a great job. Thank you for your patience and perseverance with getting this off the ground.

Aimee Shear - Senior Research Executive

We partnered up with the Cimigo team on what was a particularly challenging project – we were faced with numerous timeline delays and logistical concerns – yet Cimigo were incredibly accommodating through their patience, flexibility and commitment. Not only were Cimigo supportive during the set up of our project, but we were really impressed by the outputs delivered – Cimigo were insightful, rich and very comprehensive. Cimigo were brilliant partners to work with and we look forward to working with them again.

Over the last 5 years I have worked with Cimigo on a wide array of projects, ranging from market segmentation to product testing. At all times, I found Cimigo to be swift in response and providing high quality insights and business recommendations applicable to our business. Furthermore, I am satisfied with Cimigo fieldwork quality despite the crunched timeline that we had in some projects. Overall, I highly recommend Cimigo for their professionalism.

Tania Desela - Senior Product Manager

It was a pleasure working with Cimigo. Their expertise in consumer and market research was a significant benefit as they assisted our organization in understanding our market position in more detail and validating our hypothesis in go-to-market strategy. We were more than happy with the findings and would definitely recommend Cimigo.

Thu Phung - CTI Manager

Cimigo is not the type of agency that "fill in the template", but it's customized as per the needs and expectations of Client. Cimigo makes research interesting by applying new approaches to address the business issue, for example, it's known by default that product test is CLT, but at Cimigo, we did group debate for deeper understandings and insights and that resulted as a winning product which is selling well in the market. Last but not least, Cimigo makes me understand that research is a journey, not just a project."

Linda Yeoh - CMI Manager

We have worked with Cimigo over 2 projects in Vietnam. Cimigo has proven to be reliable being on top of the projects, managing different stakeholders and business objectives. They are flexible in terms of ways of working and are able to cope with last minute changes.

Thank you Cimigo team for supporting us.
