RTS Link could shift SG$1.05 billion of annual Singapore spending to Johor Bahru

The Johor Bahru-Singapore Rapid Transit System Link will do more than shorten a border crossing. It could integrate two neighbouring cities into a single shopping and leisure catchment, with money moving more freely in both directions.

The four-kilometre railway is scheduled to open in January 2027, connecting Woodlands North and Bukit Chagar. Trains will take approximately five minutes and carry up to 10,000 passengers per hour in each direction during peak periods. Travellers will clear border controls for both countries before departure.

This combination is significant because it removes uncertainty as well as travel time. A journey that feels like an expedition can become a planned dinner, pharmacy visit or weekend shopping trip.

The headline loss disguises two growing markets

A study commissioned by three trade groups -- the Singapore Business Federation, Restaurant Association of Singapore and Singapore Retailers Association -- models the commercial outcome. Its base case puts additional annual spending by Singapore residents in Johor Bahru at SG$1.05 billion. Increased spending by Johor Bahru visitors in Singapore is estimated to reach SG$756 million.

The result is a SG$290 million net outflow from Singapore. This equates to 0.4% of the city-state’s 2025 retail and food-and-beverage sales. While the percentage appears modest, the economy-wide average hides concentrated damage.

Groceries face the highest outbound exposure, followed by pharmacies, dining and beauty services. The study assigns net outflows of SG$104 million to western Singapore and SG$103 million to the north-east. The north is expected to lose SG$82 million, while the east loses SG$25 million.

Central Singapore, by contrast, is projected to gain SG$25 million. Premium retail, entertainment, hotels and dining are expected to attract much of this inbound spending.

The corridor creates two distinct competitive arenas. Johor Bahru can capture frequent, value-led purchases from Singaporean households, while Singapore can attract less frequent visits characterised by higher transaction values and stronger destination appeal.

Volume will not translate automatically into profit

The study starts with approximately 19.4 million annual round trips from Singapore to Johor Bahru, compared to 5.9 million in the opposite direction. It projects additions of 11.2 million and 3.3 million trips respectively, resulting in an estimated daily ridership of 39,700 trips.

Such volumes support extended opening hours and larger inventories near Bukit Chagar. However, Johor operators should avoid equating footfall with margin. Higher grocery traffic can boost sales while simultaneously increasing spoilage, staffing requirements and working-capital costs.

Singaporean merchants face the inverse challenge. Matching Johor’s prices would compress margins without alleviating Singapore’s high rent and labour costs. A more effective response is to offer convenience, trust and experiences that defy simple item-by-item price comparisons.

The line will connect directly to Singapore’s Thomson-East Coast Line, widening the practical catchment beyond Woodlands. As Bukit Chagar becomes a new commercial gateway, malls and high streets on both sides must treat station accessibility as part of the product.

The impact on hotels is mixed. A fast crossing can enable more day trips, potentially reducing room demand. Conversely, it could support "two-city" packages that pair events in Singapore with dining or accommodation in Johor.

Johor respondents highlighted an opportunity for Singapore: some 34% intend to visit for events after the launch, up from 24% today. Respondents who expected to switch from driving to rail indicated a preference for overnight stays and entertainment.

The forecast needs a hard stress test

The research surveyed approximately 1,700 Singaporean and 400 Johor consumers in March 2026. It utilised transaction data from Mastercard, government statistics, industry consultations and focus groups.

The authors describe these results as scenario estimates. The base case depends on trip growth, rail adoption rates, spending per visit and the degree of substitution between local and cross-border purchases. Stated intentions may not translate into transactions.

The model does not explicitly quantify the impact of exchange rates, rail fares, broader economic conditions or consumer sentiment. Nor does it fully account for how landlords, businesses and event organisers might adapt. Any of these factors could significantly alter traffic or average spending.

Consequently, the SG$290 million figure is useful as a stress-test figure, not a budget. Operators should develop plans based on ranges and refine them using observed conversion rates, basket sizes and repeat visit data after the launch.

Even a small proportional shift can harm exposed neighbourhood businesses, which may have less cash, data or management capacity than major retail chains.

Converting mobility into margin

Success will require designing for a corridor, not just a station. Johor grocers, pharmacies and beauty operators need reliable replenishment, transparent pricing and efficient checkout systems. They should validate stock levels against actual demand before expanding fixed costs.

Singaporean retailers require exclusivity, robust after-sales service and products that justify the journey. Restaurants can bundle reservations with events, while hotels might offer late check-in and onward transport. Entertainment operators could time sessions to coincide with train schedules.

Small businesses must prioritise productivity over promotion. Shared delivery, digital ordering and demand-based staffing can help absorb customer growth without a linear increase in labour costs. Landlords can assist by sharing footfall data and coordinating tenant offers.

Supply chains will also follow consumers. Distributors serving both markets can pool forecasts and position inventory closer to demand. However, currency fluctuations and cross-border compliance costs can turn apparent purchasing gains into margin losses.

The three trade associations have proposed measures to support consumption, enhance visitor experiences and encourage flexible operating models. While these may soften the transition, they cannot protect every existing revenue stream.

The strategic task is clear: Johor businesses must convert price advantages into dependable service without overbuilding capacity, while Singaporean businesses must turn higher costs into distinctive value. The railway provides the mobility; management will determine who retains the margin.
