Singapore's economy is not only the most open in the world, it is also the 7th least corrupt, the lowest taxed and is governed by laws that have been rated the most pro-business in the world. Given all these factors, it is easy to see why the Singaporean markets continue to soar and why so much foreign money pours through its companies. If you are looking to make the most out of this powerful and influential economy, then it is worth learning about what drives it. Here we look at the most prominent industries in Singapore.

Tourism

With millions upon millions of foreign visitors coming to Singapore every year, it is no shock to find out just how important tourism is to the economy. In fact, it is the biggest service sector in the state and is estimated to rake in about $30 million in 2015. What makes Singapore such a trap for tourists? Well, alongside its rich history, it fascinating clash of Chinese, Malay, Indian, Arab and Western cultures and it stunning conservation sites, it also has a glorious climate and some wonderful beaches. Business travellers also make up a huge percentage of the 17 million odd arrivals that come to the island each year, while retail and medical tourism are both also on the rise. Among the big names brands associated with Singaporean tourism are Singapore airlines (voted best airline in the world), Shangri-La hotels and Changi Airport (voted the world's best airport).

Banking

Given the free-flowing nature of its economy it was inevitable that the financial sector would feature on this list. Singapore's banks, wealth management firms and lenders are some of the most important business engines of South East Asia. Thanks to the extremely pro-business nature of its laws and its superbly gifted multicultural workforce, the island attracts tons and tons of investment and many of the world's biggest companies have money here. International trading takes place right around the clock, 24/7.

Construction

One of Singapore's most rapidly growing industries over the last decade or so, construction now sits at the top table as one of the economy's pillars. Its expansion has been quite remarkable to witness: in the year 2007 it grew a whopping 20% and has not stopped since. With shopping malls, casinos, hotels, apartments and much, much more being planned for the next year, it is only likely to get bigger.

Biomedical Science

The island of Singapore is now one of the world's most important centres for bio-medical progress. Key research and development projects are constantly being done here, while production and manufacturing of medical goods and the provision of medical services are also massive areas of growth. One indicator of the sector's rapid expansion is MerLion Pharmaceuticals, who received a Scrip award as the Best Company in an Emerging Market.

Logistics

Singapore is the world's most powerful hub for logistics services, according to the World Bank. The importance of this factor cannot be overstated, as it allows Singapore a huge influence in the global business community, as companies across the world rely on its logistics innovations. The island is home to Asia's most important logistics education centre, The Logistics Institute Asia Pacific.

Singapore remains one of the world's most open economies and its love affair with the free market continues apace.

Getting in on the ground floor with these industries could be key to maximising your investment in Singapore.

Gambling

Though, traditionally, gambling was against the law in the Singapore, two major casinos have recently popped up on the island – the Marina Bay Sands and the Resorts World Sentosa. Since they opened their doors in 2010, these two hotspots have brought an estimated $30 billion to the local economy and put even more juice into the always booming tourist trade. The job market has been a big winner too, with around 30,000 jobs created either directly or indirectly by the casinos. Singapore Pools is a not-for-profit organisation, set up to counter illegal gambling activities in Singapore by providing a legal and safe environment for those who wish to bet. 70% of Singapore Pools' revenue goes to prize payouts while 27% goes to taxes and surpluses which are channelled to good causes. Operating expense is kept low at 3%. Though there are still careful regulations in place to stop the seedier elements of gambling from spoiling the tranquillity and peacefulness of the island, gaming and gambling is likely to becoming a more and more prominent part of the economy in years to come.

Healthcare

Singapore is the proud home of Asia's best healthcare system, which makes it one of the most reliable and high quality healthcare system's worldwide. The proof of this is in the rapid growth of medical tourism in the last decade, with about 1 million people touching down in Singapore each year specifically to access its hospitals and doctors. The government wishes to keep increasing this number too, so one could do a lot worse than invest in Singaporean medicine.

Education

Like its medical system, Singapore's education system is one of the world's best and, thus, it attracts students from across the world to its institutions every year. The island has a long standing commitment to excellence in this field and standards are impeccably high. As most courses are thought through English, it gives Singapore a very wide catchment for potential students. This, along with the safety and standard of living offered in Singapore, makes it a very appealing prospect for young people looking for the best of the best from their third level schooling.

Media and communications

Over the last five years or so, Singapore has emerged as one of the main media cities in Asia. This is the result of a concerted effort from its government to boost its relationships with foreign media businesses, with new channels and home-grown movie projects. Video games are another hugely important part of Singapore's media sector and are expected to keep growing in the next few years. Global media brands such as Disney, BBC, ESPN and Discovery all have offices in Singapore.

There are increasing signs in Singapore's property markets that the home loans most favoured in 2015 will be fixed rates. The fundamental driving force behind this trend is this: there are strong hints coming from the USA that there will be cutbacks on stimulus spending. The knock-on effect of this speculation is that borrowers will be increasingly wary about the possibility of interest rates increasing. Those customers currently on a floating rate home loan may well find themselves suffering adversely due to the sudden interest rate rise, as well as rate fluctuations that are unpredictable.

One example would be to consider what is being offered by the DBS (formerly the Development Bank of Singapore). One of Asia's largest financial services organisations, with 250-plus branches in 16 markets, DBS has been at the forefront of investment, savings and loans for some time. It is widely respected as one of the safest banks in Asia. DBS stated they saw a rise in customers opting for fixed rate home loans by up to 30% from the previously collated 2013 figure of 10%. A spokesman stated that it was seen as a smart move for borrowers to choose this route while interest rates were low.

These particular loans are popular because they offer low interest rates in the initial stages, fixed for the first 2 to 5 years of term. Borrowers feel more comfortable with these packages because they give them greater control of their finances. This means that they are better equipped to look at the longer-term prospects for their financial arrangements.

It should be noted that floating rate packages are still available. In fact, many customers lean towards this particular type of loan because of its flexible nature. Singapore customers have many options to choose from. ANZ offer a three months ‘combo package' that takes its rate – 1.3% - from an average of the Sibor and Swap Offer Rate offered by the Association of Banks in Singapore. This gives customers and even lower percentage than the fixed-rate package of 1.65%.
