In certain Chinese cities, retirees participate in community mutual aid activities and accumulate credits convertible into care services. In Indonesia, a pilot program of community-based long-term care centers was implemented in connection with local public health structures: you give today, you receive tomorrow. Initial data is encouraging, but the question of scale remains open as Asia urbanizes at breakneck speed.
The essentials
- Community time banks allow seniors to exchange services for credits usable later, with oversight and support from public institutions.
- In Indonesia, five community care hubs (three in Yogyakarta, two in Bali) connect seniors and caregivers to local public health structures.
- Social cohesion facilitates these systems, but broader networks and institutional infrastructure remain necessary.
- The model offers a concrete pathway for regions where the welfare state arrives too late and where the private care market remains financially inaccessible.
Asian demographics cannot wait for state reforms
Asia is aging faster than its institutions are reforming. China is approaching the threshold where a quarter of its population will be over 60 years old. The country notably distinguishes between the employee system and the unified system for urban and rural residents, established in 2014. In Indonesia, life expectancy at birth has increased by roughly seven years or more between the early 1990s and the second half of the 2010s, but public geriatric infrastructure remains underdeveloped outside major urban centers. Private long-term care services primarily targeted high-income households.
It is in this void—too large for the family alone, too small for national policies—that time banks emerged. The principle is simple: a healthy senior dedicates a few hours per week to helping a more fragile neighbor. Each hour worked is recorded as a credit. When that senior needs help in turn, they can draw on this account. The idea is not new in itself; early Japanese experiments date to the 1990s, but the Indonesian program sought to connect community-based long-term care centers to local health resources.
The Indonesian model
The Indonesian program benefits from a favorable context: intact intergenerational trust networks in rural areas, and the ability to coordinate with existing public health structures. These conditions are not universal. They explain why the program works where it works, and why its generalization raises questions that current data do not yet settle.
In Indonesia, the wager on clinical anchoring
The Indonesian approach is documented by an ADB publication from January 2026 devoted to a pilot community long-term care program, and rests on a different architecture. The five community care hubs, three in Yogyakarta, two in Bali, do not function as autonomous time banks. They coordinate directly with local public clinics, called Puskesmas. Managers and community leaders of the network receive training in screening and care for elderly people.
This choice of anchoring is strategic. The program coordinates with local public health structures, which distinguishes this approach from informal initiatives operating parallel to institutions. In Yogyakarta, LLT managers received training in screening, case management, and care procedures for elderly people. Their work becomes an extension of the health system, not a stopgap for its absence.
What this model produces goes beyond simple mutual aid. It creates a local care economy where skills previously invisible—knowing how to support someone, knowing how to listen, knowing how to cook for a diabetic person—become traceable, valued, and recognized. It is a transformation of the social status of the elderly as much as a logistical solution.
The urbanization wall: the limits of these models
Scaling up raises questions of governance, financing, and infrastructure. Interpersonal trust can facilitate participation in time banks, but documented programs also depend on institutional infrastructure. In Foshan as in Yogyakarta, participants know each other, sometimes since childhood, often for decades.
Urbanization can affect the formation of these networks. Rural departure can weaken certain local ties, but it does not necessarily mean the disappearance of social networks usable by a time bank. It gains anonymity that renders each exchange uncertain. Japanese experiments in the 1990s and 2000s ran into this problem: the Fureai Kippu, the first mutual aid tickets for elderly people, thrived in stable rural areas and declined in mobile urban areas.
Southeast Asia is experiencing rapid urbanization. According to available World Bank data, Indonesia’s urban share should exceed 60% by 2035. The documented models also exist in urban settings, but their expansion and large-scale effects remain to be evaluated. These tools can support expansion, but their effect on the scope of the program has not been demonstrated by the sources consulted.
A few Chinese cities, including Shanghai, are experimenting with digital variants of time banks. These systems use mobile applications to record credits, validate exchanges, and connect strangers. Longitudinal monitoring of these urban variants remains limited. But the fact that they are emerging signals that the model is actively seeking a form suited to the city.
Intergenerational transfers on the horizon of 2040
Time banks constitute a care mechanism, but they also raise an issue that Asian demographics make urgent: organizing intergenerational transfers by drawing on local capital (skills, time, trust) while benefiting from public institutional support.
The answer to this question will affect the trajectories of millions of people in the years to come. China and Indonesia are not alone in this situation: Vietnam, the Philippines, and Thailand face similar demographic curves with incomplete systems of social protection. What Foshan and Yogyakarta are testing is therefore of interest beyond their borders.
Two scenarios are emerging for the next twenty years, without either being guaranteed. In the first, time banks remain effective local solutions in cohesive rural areas, complementary to a welfare state that gradually builds capacity. In this scenario, their role is real but limited: they stabilize communities that the state cannot yet serve, and allow millions of seniors to age with a dignity that neither market nor state yet offer them. This scenario requires that states continue to invest in their social coverage, and that time banks do not become a pretext for deferring this investment.
In the second scenario, hybrid time banks, articulating community exchange and digital platforms, manage to reproduce in cities the trust that villages generate naturally. This scenario requires institutional innovations that current programs do not yet test at large scale: credit guarantee systems allowing a senior to use their credits even if the network weakens, legal frameworks recognizing the value of exchanged time, and interoperability with public health systems. This is the most ambitious scenario, and the one for which evidence remains least advanced.
Personnel mobility is a sustainability factor among others, along with governance, financing, training, and infrastructure. A senior who accumulated credits in Foshan and could use them in another city would transform the nature of the model. Strictly local and non-transferable credits would make it a village solution in a mobile world. Chinese digital initiatives are exploring the portability of credits between geographic zones.
The link to aging work is direct. Research on automation and redistribution of productivity gains, such as that addressed in robotization in factories, shows that productivity gains do not redistribute spontaneously. Time banks raise the same issue in the register of care: if the local productivity of seniors increases by 40%, it remains to determine who captures this value and through what mechanisms it returns to those who produced it.
The role of states
The error would be to treat these programs as an alternative to the state. The sources consulted show integration with existing public institutions in both contexts. The anchoring of Indonesian hubs to Puskesmas is the clearest illustration.
A public framework can strengthen the continuity of the system, structured training of caregivers, coordination between zones, and network stability. Time banks benefit from institutional support to ensure their sustainability and adaptation to social and economic changes.
States must avoid using these experiments as an argument for deferring the expansion of their social coverage. The risk is real: a community model that works can become a convenient pretext for governments struggling to fund their social protection. Rural populations have the right to structured coverage, and time banks find their usefulness in the space between what exists and what should exist, without shrinking that space.
Two programs that pose the right questions
The Indonesian program does not solve the problem of aging in Asia. At small scale, it has implemented coordinated community services linked to local public structures. These results deserve to be monitored over time.
The initial results of the Indonesian program are solid enough to continue experimentation. The next step is to document over time how accumulated credits function, how the model adapts to population mobility, and what role digital urban variants play. These answers will clarify the possible role of time banks alongside the systems of social protection that must adapt to the needs of aging populations.
