Following the Money: Tourism’s revenue crisis behind the arrival numbers – PART II
(Article 2 of the 4-part series on Sri Lanka’s tourism stagnation)
If Sri Lanka’s tourism story were a corporate income statement, the top line would satisfy any minister. Arrivals went up 15.1%, targets met, records broke. But walk down the statement and the story darkens. Revenue barely budges. Per-visitor yield collapses. The money that should accompany all those arrivals has quietly vanished, or, more accurately, never materialised.
This is not a recovery. It is a volume trap, more tourists generating less wealth, with policymakers either oblivious to the math or unwilling to confront it.
Problem Diagnosis: The Paradox of Plenty:
The numbers tell a brutal story.
Read that again: arrivals grew 15.1% year-on-year, but revenue grew only 1.6%. The average tourist in 2025 left behind $181 less than in 2024, an 11.7% decline. Compared to 2018, the drop is even sharper. In real terms, adjusting for inflation and currency depreciation, each visitor in 2025 generates approximately 27-30% less revenue than in 2018, despite Sri Lanka being “cheaper” due to the rupee’s collapse. This is not marginal variance. This is structural value destruction. (See Table 1)

The math is simple and damning: Sri Lanka is working harder for less. More tourists, lower yield, thinner margins. Why? Because we have confused accessibility with competitiveness. We have made ourselves “affordable” through currency collapse and discounting, not through value creation.
Root Causes: The Five Mechanisms of Value Destruction
The yield collapse is not random. It is the predictable outcome of specific policy failures and market dynamics.
1. Currency Depreciation as False Competitiveness
The rupee’s collapse post-2022 has made Sri Lanka appear “cheap” to foreigners. A hotel room priced at $100 in 2018 might cost $70-80 in effective purchasing power today due to depreciation. Tour operators have aggressively discounted to fill capacity during the crisis recovery.
This creates the illusion of competitiveness. Arrivals rise because we are a “bargain.” But the bargain is paid for by domestic suppliers, hotels, transport providers, restaurants, staff, whose input costs (energy, food, imported goods) have skyrocketed in rupee terms while room rates lag in dollar terms.
The transfer is explicit: value flows from Sri Lankan workers and businesses to foreign tourists. The tourism “recovery” extracts wealth from the domestic economy rather than injecting it.
2. Market Composition Shift: Trading European Yields for Asian Volumes
SLTDA data shows a deliberate (or accidental—the policy opacity makes it unclear) shift in source markets. (See Table 2)

The problem is not that we attract Indians or Russians, it is that we attract them without strategies to optimise their yield. As the next article in this series will detail, Indian tourists average approximately 5.27 nights compared to the 8-9 night overall average, with lower per-day spending. We have built recovery on volume from price-sensitive segments rather than value from high-yield segments.
This is a choice, though it appears no one consciously made it. Visa-free entry, aggressive India-focused marketing, and price positioning have tilted the market mix without any apparent analysis of revenue implications.
3. Length of Stay Decline and Activity Compression
Average length of stay has compressed. While overall averages hover around 8-9 nights in recent years, the composition matters. High-yield European and North American tourists who historically spent 10-12 nights are now spending 7-9. Indian tourists spend 5-6 nights.
Shorter stays mean less cumulative spending, fewer experiences consumed, less distribution of value across the tourism chain. A 10-night tourist patronises multiple regions, hotels, guides, restaurants. A 5-night tourist concentrates spending in 2-3 locations, typically Colombo, one beach, one cultural site.
The compression is driven partly by global travel trends (shorter, more frequent trips) but also by Sri Lanka’s failure to develop compelling multi-day itineraries, adequate inter-regional connectivity, and differentiated regional experiences. We have not given tourists reasons to stay longer.
4. Infrastructure Decay and Experience Degradation
Tourists pay for experiences, not arrivals. When experiences degrade, airport congestion, poor road conditions, inadequate facilities at cultural sites, safety concerns, spending falls even if arrivals hold.
The 2024-2025 congestion at Bandaranaike International Airport, with reports of tourists nearly missing flights due to bottlenecks, is the visible tip. Beneath are systemic deficits: poor last-mile connectivity to tourism sites, deteriorating heritage assets, unregistered businesses providing sub-standard services, outbound migration of trained staff.
An ADB report notes that tourism authorities face resource shortages and capital expenditure embargoes, preventing even basic facility improvements at major revenue generators like Sigiriya (which charges $36 per visitor and attracts 25% of all tourists). When a site generates substantial revenue but lacks adequate lighting, safety measures, and visitor facilities, the experience suffers, and so does yield.
5. Leakage: The Silent Revenue Drain
Tourism revenue figures are gross. Net foreign exchange contributions after leakages, is rarely calculated or published.
Leakages include:
· Imported food, beverages, amenities in hotels (often 30-40% of operating costs)
· Foreign ownership and profit repatriation
· International tour operators taking commissions upstream (tourists book through foreign platforms that retain substantial margins)
· Unlicensed operators and unregulated businesses evading taxes and formal banking channels
Industry sources estimate leakages can consume 40-60% of gross tourism revenue in developing economies with weak regulatory enforcement. Sri Lanka has not published comprehensive leakage studies, but all indicators, weak licensing enforcement, widespread informal sector activity, foreign ownership concentration in resorts, suggest leakages are substantial and growing.
The result: even the $3.22 billion headline figure overstates actual net contribution to the economy.
The Way Forward: From Volume to Value
Reversing the yield collapse requires
systematic policy reorientation, from arrivals-chasing to value-building.
First
, publish and track yield metrics as primary KPIs. SLTDA should report:
· Revenue per visitor (by source market, by season, by purpose)
· Average daily expenditure (disaggregated by accommodation, activities, food, retail)
· Net foreign exchange contribution after documented leakages
· Revenue per room night (adjusted for real exchange rates)
Make these as visible as arrival numbers. Hold policy-makers accountable for yield, not just volume.
Second
, segment markets explicitly by yield potential. Stop treating all arrivals as equivalent. Conduct market-specific yield analyses:
· Which markets spend most per day?
· Which stays longest?
· Which distributes spending across regions vs. concentrating in Colombo/beach corridors?
· Which book is through formal channels vs. informal operators?
Target marketing and visa policies accordingly. If Western European tourists spend $250/day for 10 nights while another segment spends $120/day for 5 nights, the revenue difference ($2,500 vs. $600) dictates where promotional resources should flow.
Third
, develop multi-day, multi-region itineraries with compelling value propositions. Tourists extend stays when there are reasons to stay. Create integrated experiences:
· Cultural triangle + beach + hill country circuits with seamless connectivity
· Themed tours (wildlife, wellness, culinary, adventure) requiring 10+ days
· Regional spread of accommodation and experiences to distribute economic benefits
This requires infrastructure investment, precisely what has been neglected.
Fourth
, regulations to minimise leakages. Enforce licensing for tourism businesses. Channel bookings through formal operators registered with commercial banks. Tax holiday schemes should prioritise investments that maximise local value retention, staff training, local sourcing, domestic ownership.
Fifth
, stop using currency depreciation as a competitive strategy. A weak rupee makes Sri Lanka “affordable” but destroys margins and transfers wealth outward. Real competitiveness comes from differentiated experiences, quality standards, and strategic positioning, not from being the “cheapest” option.
The Hard Math: What We’re Losing
Let’s make the cost explicit. If Sri Lanka maintained 2018 per-visitor spending levels ($1,877) on 2025 arrivals (2.36 million), revenue would be approximately $4.43 billion, not $3.22 billion. The difference: $1.21 billion in lost revenue, value that should have been generated but wasn’t.
That $1.21 billion is not a theoretical gap. It represents:
· Wages not paid
· Businesses not sustained
· Taxes not collected
· Infrastructure not funded
· Development not achieved
This is the cost of volume-chasing without yield discipline. Every year we continue this model; we lock in value destruction.
The Policy Failure: Why Arrivals Theater Persists
Why do policymakers fixate on arrivals when revenue tells the real story?
Because arrivals are politically legible. A minister can tout “record tourist numbers” in a press conference. Revenue per visitor requires explanation, context, and uncomfortable questions about policy choices.
Arrivals are easy to manipulate upward, visa-free entry, aggressive discounting, currency depreciation. Yield is hard, it requires product development, market curation, infrastructure investment, regulatory enforcement.
Arrivals theater is cheaper and quicker than strategic transformation. But this is governance failure at its most fundamental. Tourism’s contribution to economic recovery is not determined by how many planes land but by how much wealth each visitor creates and retains domestically. Every dollar spent celebrating arrival records while ignoring yield collapse is a waste of dollars.
The Uncomfortable Truth
Sri Lanka’s tourism “boom” is real in volume, but it is a value bust. We are attracting more tourists and generating less wealth. The industry is working harder for lower returns. Margins are compressed, staff are paid less in real terms, infrastructure decays, and the net contribution to national recovery underperforms potential.
This is not sustainable. Eventually, operators will exit. Quality will degrade further. The “affordable” positioning will shift to “cheap and deteriorating.” The volume will follow yield down.
We have two choices: acknowledge the yield crisis and reorient policy toward value creation or continue arrivals theater until the hollowness becomes undeniable.
The money has spoken. The question is whether anyone in power is listening.

Retirement age for judges: Innovation and policy
I. The Constitutional Context
Independence of the judiciary is, without question, an essential element of a functioning democracy. In recognition of this, ample provision is made in the highest law of our country, the Constitution, to engender an environment in which the courts are able to fulfil their public responsibility with total acceptance.
As part of this protective apparatus, judges of the Supreme Court and the Court of Appeal are assured of security of tenure by the provision that “they shall not be removed except by an order of the President made after an address of Parliament supported by a majority of the total number of members of Parliament, (including those not present), has been presented to the President for such removal on the ground of proved misbehaviour or incapacity”[Article 107(2)]. Since this assurance holds good for the entirety of tenure, it follows that the age of retirement should be defined with certainty. This is done by the Constitution itself by the provision that “the age of retirement of judges of the Supreme Court shall be 65 years and of judges of the Court of Appeal shall be 63 years”[Article 107(5)].
II. A Proposal for Reform
This provision has been in force ever since the commencement of the Constitution. Significant public interest, therefore, has been aroused by the lead story in a newspaper, Anidda of 13 March, that the government is proposing to extend the term of office of judges of the Supreme Court and the Court of Appeal by a period of two years.
This proposal, if indeed it reflects the thinking of the government, is deeply disturbing from the standpoint of policy, and gives rise to grave consequences. The courts operating at the apex of the judicial structure are called upon to do justice between citizens and also between the state and members of the public. It is an indispensable principle governing the administration of justice that not the slightest shadow of doubt should arise in the public mind regarding the absolute objectivity and impartiality with which the courts approach this task.
What is proposed, if the newspaper report is authentic, is to confer on judges of two particular courts, the Supreme Court and the Court of Appeal, a substantial benefit or advantage in the form of extension of their years of service. The question is whether the implications of this initiative are healthy for the administration of justice.
III. Governing Considerations of Policy
What is at stake is a principle intuitively identified as a pillar of justice.
Reflecting firm convictions, the legal antecedents reiterate the established position with remarkable emphasis. The classical exposition of the seminal standard is, of course, the pronouncement by Lord Hewart: “It is not merely of some importance, but is of fundamental importance that justice should not only be done, but should manifestly and undoubtedly be seen to be done”. (Rex v. Sussex Justices, ex parte McCarthy). The underlying principle is that perception is no less important than reality. The mere appearance of partiality has been held to vitiate proceedings: Dissanayake v. Kaleel. In particular, reasonableness of apprehension in the mind of the parties to litigation is critical: Ranjit Thakur v. Union of India, a reasonable likelihood of bias being necessarily fatal (Manak Lal v. Prem Chaud Singhvi).
The overriding factor is unshaken public confidence in the judiciary: State of West Bengal v. Shivananda Pathak. The decision must be “demonstrably” (Saleem Marsoof J.) fair. The Bar Association of Sri Lanka has rightly declared: “The authority of the judiciary ultimately depends on the trust reposed in it by the people, which is sustained only when justice is administered in a visibly fair manner”.
Credibility is paramount in this regard. “Justice has to be seen to be believed” (J.B. Morton). Legality of the outcome is not decisive; process is of equal consequence. Judicial decisions, then, must withstand public scrutiny, not merely legal technicality: Mark Fernando J. in the Jana Ghosha case. Conceived as continuing vitality of natural justice principles, these are integral to justice itself: Samarawickrema J. in Fernando v. Attorney General. Institutional integrity depends on eliminating even the appearance of partiality (Mandal Vikas Nigam Ltd. v. Girja Shankar Pant), and “open justice is the cornerstone of our judicial system”: (Sahara India Real Estate Corporation Ltd. v. SEBI).
IV. Practical Constraints
Apart from these compelling considerations of policy, there are practical aspects which call for serious consideration. The effect of the proposal is that, among all judges operating at different levels in the judicature of Sri Lanka, judges of the Supreme Court and the Court of Appeal only, to the exclusion of all other judges, are singled out as the beneficiaries of the proposal. An inevitable result is that High Court and District Judges and Magistrates will find their avenues of promotion seriously impeded by the unexpected lengthening of the periods of service of currently serving judges in the two apex courts. Consequently, they will be required to retire at a point of time appreciably earlier than they had anticipated to relinquish judicial office because the prospect of promotion to higher courts, entailing higher age limits for retirement, is precipitately withdrawn. Some degree of demotivation, arising from denial of legitimate expectation, is therefore to be expected.
A possible response to this obvious problem is a decision to make the two-year extension applicable to all judicial officers, rather than confining it to judges of the two highest courts. This would solve the problem of disillusionment at lower levels of the judiciary, but other issues, clearly serious in their impact, will naturally arise.
Public service structures, to be equitable and effective, must be founded on principles of non-discrimination in respect of service conditions and related matters. Arbitrary or invidious treatment is destructive of this purpose. In determining the age of retirement of judges of the Supreme Court and the Court of Appeal, some attention has been properly paid to balance and consistency. The age of retirement of a Supreme Court judge is on par with that applicable to university professors and academic staff in the higher education system. They all retire at 65 years. Members of the public service, generally, retire at 60. Medical specialists retire at 63, with the possibility of extension in special circumstances to 65. The age of retirement for High Court Judges is 61, and for Magistrates and District Judges 60. It may be noted that the policy change in 2022 aimed at specifically addressing the issue of uniformity and compatibility.
If, then, an attempt is made to carve out an ad hoc principle strictly limited to judicial officers, not admitting of a self-evident rationale, the question would inevitably arise whether this is fair by other categories of the public service and whether the latter would not entertain a justifiable sense of grievance.
This is not merely a moral or ethical issue relating to motivation and fulfillment within the public service, but it could potentially give rise to critical legal issues. It is certainly arguable that the proposed course of action represents an infringement of the postulate of equality of treatment, and non-discrimination, enshrined in Article 12(1) of the Constitution.
There would, as well, be the awkward situation that this issue, almost certain to be raised, would then have to be adjudicated upon by the Supreme Court, itself the direct and exclusive beneficiary of the impugned measure.
V. Piecemeal Amendment or an Overall Approach?
If innovation on these lines is contemplated, would it not be desirable to take up the issue as part of the new Constitution, which the government has pledged to formulate and enact, rather than as a piecemeal amendment at this moment to the existing Constitution? After all, Chapter XV, dealing with the Judiciary, contains provisions interlinked with other salient features of the Constitution, and an integrated approach would seem preferable.
VI. Conclusion
In sum, then, it is submitted that the proposed change is injurious to the institutional integrity of the judiciary and to the prestige and stature of judges, and that it should not be implemented without full consideration of all the issues involved.

Ranked 134th in Happiness: Rethinking Sri Lanka’s development through happiness, youth wellbeing and resilience
In recent years, Sri Lanka has experienced a succession of overlapping challenges that have tested its resilience. Cyclone Ditwah struck Sri Lanka in November last year, significantly disrupting the normal lives of its citizens. The infrastructure damage is much more serious than the tsunami. According to World Bank reports and preliminary estimates, the losses amounted to approximately US$ 4.1 billion, nearly 4 per cent of the country’s Gross Domestic Product. Before taking a break from that, the emerging crisis in the Middle East has once again raised concerns about potential economic repercussions. In particular, those already affected by disasters such as Cyclone Ditwah risk falling “from the frying pan into the fire,” facing multiple hardships simultaneously. Currently, we see fuel prices rising, four-day workweeks, a higher cost of living, increased pressure on household incomes, and a reduction in the overall standard of living for ordinary citizens. It would certainly affect people’s happiness. As human beings, we naturally aspire to live happy and fulfilling lives. At a time when the world is increasingly talking about happiness and wellbeing, the World Happiness Report provides a useful way of looking at how countries are doing. The World Happiness Report discusses global well-being and offers strategies to improve it. The report is produced annually with contributions from the University of Oxford’s Wellbeing Research Centre, Gallup, the UN Sustainable Development Solutions Network, and other stakeholders. There are many variables taken into consideration for the index, including the core measure (Cantril Ladder) and six explanatory variables (GDP per Capita ,Social Support,Healthy Life Expectancy,Freedom to Make Life Choices,Generosity,Perceptions of Corruption), with a final comparison.
According to the recently published World Happiness Report 2026, Sri Lanka ranks 134th out of 147 nations. As per the report, this is the first time that Sri Lanka has suffered such a decline. Sri Lanka currently trails behind most of its South Asian neighbours in the happiness index. The World Happiness Report 2026 attributes Sri Lanka’s low ranking (134th) to a combination of persistent economic struggles, social challenges, and modern pressures on younger generations. The 2026 report specifically noted that excessive social media use is a growing factor contributing to declining life satisfaction among young people globally, including in Sri Lanka. This calls for greater vigilance and careful reflection. These concerns should be examined alongside key observations, particularly in the context of education reforms in Sri Lanka, which must look beyond their immediate scope and engage more meaningfully with the country’s future.
In recent years, a series of events has triggered political upheaval in countries such as Nepal, characterised by widespread protests, government collapse, and the emergence of interim administration. Most reports and news outlets described this as “Gen Z protests.” First, we need to understand what Generation Z is and its key attributes. Born between 1997 and 2012, Generation Z represents the first truly “digital native” generation—raised not just with the internet, but immersed in it. Their lives revolve around digital ecosystems: TikTok sets cultural trends, Instagram fuels discovery, YouTube delivers learning, and WhatsApp sustains peer communities. This constant, feed-driven engagement shapes not only how they consume content but how they think, act, and spend. Tech-savvy and socially aware, Gen Z holds brands to a higher standard. For them, authenticity, transparency, and accountability—especially on environmental and ethical issues—aren’t marketing tools; they’re baseline expectations. We can also observe instances of them becoming unnecessarily arrogant in making quick decisions and becoming tools of some harmful anti-social ideological groups. However, we must understand that any generation should have proper education about certain aspects of the normal world, such as respecting others, listening to others, and living well. More interestingly, a global survey by the McKinsey Health Institute, covering 42,083 people across 26 countries, finds that Gen Z reports poorer mental health than older cohorts and is more likely to perceive social media as harmful.
Youth health behaviour in Sri Lanka reveals growing concerns in mental health and wellbeing. Around 18% of youth (here, school-going adolescents aged 13-17) experience depression, 22.4% feel lonely, and 11.9% struggle with sleep due to worry, with issues rising alongside digital exposure. Suicide-related risks are significant, with notable proportions reporting thoughts, plans, and attempts, particularly among females. Bullying remains a significant concern, particularly among males, with cyberbullying emerging as a notable issue. At the same time, substance use is increasing, including tobacco, smokeless tobacco, and e-cigarettes. These trends highlight the urgent need for targeted interventions to support youth mental health, resilience, and healthier behavioural outcomes in Sri Lanka. We need to create a forum in Sri Lanka to keep young people informed about this. Sri Lanka can designate a date (like April 25th) as a National Youth Empowerment Day to strengthen youth mental health and suicide prevention efforts. This should be supported by a comprehensive, multi-sectoral strategy aligned with basic global guidelines. Key priorities include school-based emotional learning, counselling services, and mental health training for teachers and parents. Strengthening data systems, reducing access to harmful means, and promoting responsible media reporting are essential. Empowering families and communities through awareness and digital tools will ensure this day becomes a meaningful national call to action.
As discussed earlier, Sri Lanka must carefully understand and respond to the challenges arising from its ongoing changes. Sri Lanka should establish an immediate task force comprising responsible stakeholders to engage in discussions on ongoing concerns. Recognising that it is not a comprehensive solution, the World Happiness Index can nevertheless act as an important indicator in guiding a paradigm shift in how we approach education and economic development. For a country seeking to reposition itself globally, Sri Lanka must adopt stronger, more effective strategies across multiple sectors. Building a resilient and prosperous future requires sound policymaking and clear strategic direction.

Hidden diversity in Sri Lanka’s killifish revealed: New study reshapes understanding of island’s freshwater biodiversity
A groundbreaking new study led by an international team of scientists, including Sri Lankan researcher Tharindu Ranasinghe, has uncovered striking genetic distinctions in two closely related killifish species—reshaping long-standing assumptions about freshwater biodiversity shared between Sri Lanka and India.
Published recently in Zootaxa, the research brings together leading ichthyologists such as Hiranya Sudasinghe, Madhava Meegaskumbura, Neelesh Dahanukar and Rajeev Raghavan, alongside other regional experts, highlighting a growing South Asian collaboration in biodiversity science.
For decades, scientists debated whether Aplocheilus blockii and Aplocheilus parvus were in fact the same species. But the new genetic analysis confirms they are “distinct, reciprocally monophyletic sister species,” providing long-awaited clarity to their taxonomic identity.
Speaking to The Island, Ranasinghe said the findings underscore the hidden complexity of Sri Lanka’s freshwater ecosystems.
“What appears superficially similar can be genetically very different,” he noted. “Our study shows that even widespread, common-looking species can hold deep evolutionary histories that we are only now beginning to understand.”
A tale of two fishes
The study reveals that Aplocheilus blockii is restricted to peninsular India, while Aplocheilus parvus occurs both in southern India and across Sri Lanka’s lowland wetlands.
Despite their close relationship, the two species show clear genetic separation, with a measurable “genetic gap” distinguishing them. Subtle physical differences—such as the pattern of iridescent scales—also help scientists tell them apart.
Co-author Sudasinghe, who has led several landmark studies on Sri Lankan freshwater fishes, noted that such integrative approaches combining genetics and morphology are redefining taxonomy in the region.
Echoes of ancient land bridges
The findings also shed light on the ancient biogeographic links between Sri Lanka and India.
Scientists believe that during periods of low sea levels in the past, the two landmasses were connected by the now-submerged Palk Isthmus, allowing freshwater species to move between them.
Later, rising seas severed this connection, isolating populations and driving genetic divergence.
“These fishes likely dispersed between India and Sri Lanka when the land bridge existed,” Ranasinghe said. “Subsequent isolation has resulted in the patterns of genetic structure we see today.”
Meegaskumbura emphasised that such patterns are increasingly being observed across multiple freshwater fish groups in Sri Lanka, pointing to a shared evolutionary history shaped by geography and climate.
A deeper genetic divide
One of the study’s most striking findings is that Sri Lankan populations of A. parvus are genetically distinct from those in India, with no shared haplotypes between the two regions.
Dahanukar explained that this level of differentiation, despite relatively recent geological separation, highlights how quickly freshwater species can diverge when isolated.
Meanwhile, Raghavan pointed out that these findings reinforce the importance of conserving habitats across both countries, as each region harbours unique genetic diversity.
Implications for conservation
The study carries important implications for conservation, particularly in a country like Sri Lanka where freshwater ecosystems are under increasing pressure from development, pollution, and climate change.
Ranasinghe stressed that understanding genetic diversity is key to protecting species effectively.
“If we treat all populations as identical, we risk losing unique genetic lineages,” he warned. “Conservation planning must recognise these hidden differences.”
Sri Lanka is already recognised as a global biodiversity hotspot, but studies like this suggest that its biological richness may be even greater than previously thought.
A broader scientific shift
The research also contributes to a growing body of work by scientists such as Sudasinghe and Meegaskumbura, challenging traditional assumptions about species distributions in the region.
Earlier studies often assumed that many freshwater fish species were shared uniformly between India and Sri Lanka. However, modern genetic tools are revealing a far more complex picture—one shaped by ancient geography, climatic shifts, and evolutionary processes.
“We are moving from a simplistic view of biodiversity to a much more nuanced understanding,” Ranasinghe said. “And Sri Lanka is proving to be a fascinating natural laboratory for this kind of research.”
Looking ahead
The researchers emphasise that much remains to be explored, with several freshwater fish groups in Sri Lanka still poorly understood at the genetic level.
For Sri Lanka, the message is clear: beneath its rivers, tanks, and wetlands lies a largely untapped reservoir of evolutionary history.
As Ranasinghe puts it:
“Every stream could hold a story of millions of years in the making. We are only just beginning to read them.”
