Tourism Industry Insight: Different Source-Market Calendars Can Make Tourism Demand More Resilient

Imagine two resorts entering September with identical annual occupancy and the same number of source markets. At the first, most guests come from countries whose school calendars, airline schedules and holiday patterns create demand in the same months. At the second, some markets strengthen precisely when others soften. On paper, both look diversified. Operationally, they are different. When the shoulder season arrives, one sees demand fall together; the other receives a cushion.

The important question is not only where guests come from, but when those markets tend to travel.

Diversification works when demand behaves differently

The latest MTO daily-data import, published 3 September, shows China at 18.7% of accumulated Maldives arrivals and Russia at 14.6%, meaning the two largest markets together account for about one-third of arrivals. That concentration matters, as the recent August tourism brief noted, but market share alone does not reveal the whole risk.

An earlier analysis of 20 years of Maldives arrivals showed how the destination moved from heavy European dependence toward a rotating portfolio of China, Russia, India, traditional European markets and newer long-haul demand. The next analytical step is temporal: do those markets rise and fall together?

This is the same idea that makes diversification useful in investment portfolios. Two assets provide less protection if both lose value at the same moment. Tourism markets behave similarly. A destination can have ten meaningful source markets and still experience a sharp seasonal trough if most share similar travel calendars or route reductions.

Seasonality can be treated as a portfolio

Consider a deliberately simple illustrative example. Market A supplies 100 bookings in August and 60 in September. Market B falls from 80 to 50. Adding B increases volume, but does little to smooth September because both move in the same direction.

Now imagine Market C rises from 40 bookings in August to 70 in September. It may be smaller than A, yet its timing makes it unusually valuable: its demand partly offsets the seasonal decline elsewhere.

That matters in the Maldives because September has historically been softer. IZUCT’s recent analysis of the September pattern found September arrivals below August in every selected non-pandemic comparison year from 2015–2019 and 2022–2025, with the median daily-rate decline around 12%. The opportunity is not simply to “market harder” in September. It is to identify markets whose natural travel calendars fit the gap.

The reasoning becomes stronger when volume is combined with behaviour. Booking lead time tells an operator when a market becomes visible in the forward curve. Repeat-visitor patterns show how much demand may return without being reacquired from zero. Length of stay determines how many bed-nights each arrival contributes. A smaller market with long stays, repeat demand and counter-seasonal timing can therefore be more stabilising than its arrival share suggests.

Measure the overlap before buying more demand

For destination marketers and hotel revenue teams, this suggests a different dashboard. Instead of ranking markets only by annual arrivals or room revenue, compare their monthly demand patterns. Which markets peak together? Which strengthen in weak months? Which share airline dependencies? Which react similarly to school holidays or economic shocks?

The useful metric is correlation. If two markets usually move together, their seasonal diversification benefit is limited. If one tends to strengthen when another weakens, the combination provides more smoothing. Managers do not need advanced mathematics to begin; even a heat map of monthly market shares across several years can reveal the pattern.

This does not mean abandoning large markets. Scale, connectivity and established distribution remain valuable. It means recognising that the next thousand arrivals are not equally useful in every month.

Return to those two resorts entering September. Both had diversified guest lists. Only one had diversified timing.

That distinction changes how destination resilience should be understood. A stronger tourism portfolio is not simply a collection of flags; it is a collection of demand rhythms. The market that fills a weak week, books when others hesitate, stays longer when occupancy is soft, or returns reliably may contribute more resilience than its annual ranking suggests.

In tourism, diversity becomes most valuable when different customers do not all arrive—and disappear—together.
