The strong Thai baht
- Thailand’s currency, the Thai baht, ended 2019 at its highest value in more than six years. With a 7.8 % gain against the United States dollar (US$), it was the currency that appreciated the most among major Asian currencies.
- The Thai baht’s appreciation was caused by several factors. Many foreign investors are attracted by Thailand’s economic stability, high levels of foreign reserves, low inflation rate and low unemployment (Table 1). However, the inflation rate is below the central bank’s target.
- Initially, the central bank of Thailand (BoT) was not too concerned, as the strong Thai baht was helping Thai importers and those who had foreign debts. Additionally, Thai producers could afford to import new technology and capital equipment. An appreciating currency could also help improve the country’s terms of trade.
- However, a strong currency can have severe consequences on an export-oriented country like Thailand. Exports account for 65 % of gross domestic product (GDP), and in 2019 exports declined by 7 %. Additionally, the tourism industry, which makes up approximately 20 % of GDP and accounts for 16 % of employment, started to express concern. Economic growth in 2019 was 3 %, down from 4.1 % in 2018.
- Therefore, towards the end of 2019, the BoT implemented measures to prevent further appreciation of the Thai baht. The BoT reduced controls on capital outflows to make it easier for Thai citizens to move money abroad. Additionally, restrictions were placed on the amount of money foreigners could hold in Thai bank accounts.
- The BoT is considering further measures including the use of foreign reserves, a decrease in the interest rate, and imposing controls on capital inflows, to prevent speculative inflows. However, these controls may impact the country’s credibility and financial markets. Expansionary monetary policy may also increase household debt which, at 78.6 % of GDP, is among the highest in Asia.
- The BoT is concerned about using foreign reserves, as this may result in Thailand being labelled a currency manipulator* by the US. Currently, Thailand’s overall large current account surplus is the only requirement it meets to be labelled a currency manipulator. However, Thailand’s bilateral trade surplus with the US is currently US$19 billion, which means it is close to meeting a second requirement. Thailand wants to avoid being labelled a currency manipulator as the US may use trade protection in retaliation.
* currency manipulator: the US will label a country as a currency manipulator if the following three requirements are met (a country will be placed on a watchlist if they meet two of the requirements):
1. The country is using its foreign reserves to change the value of its currency to gain an advantage
2. The country has a bilateral trade surplus with the US of over US$20 billion
3. The country has a current account surplus of more than 2 % of its GDP.

Using an exchange rate diagram, explain how a decrease in the interest rate might influence the value of the Thai baht (paragraph [6]).
[4]
NB Candidates may show a decrease in demand for the Thai baht resulting from the decreased attractiveness of /financial/ portfolio investments
This will lead to a decrease in demand and result in a depreciation/decrease in the value/price. This approach should be fully rewarded.
Candidates who incorrectly label diagrams can be awarded a maximum of [3].
For an exchange rate diagram, the vertical axis may be exchange rate, price of (Thai) baht in other currency, (Thai) baht in other currency, or other currency per THB, or OTHER CURRENCY/THB. The horizontal axis may be quantity, Q, or quantity of (Thai) baht.
It was encouraging to see that so many students were able to accurately construct and label appropriate exchange rate diagrams resulting from a cut in interest rates. Still, some labelling errors mainly occurred when students used the “other currency / Thai Baht" format incorrectly for the y-axis. Students used a variety of explanations/reasoning. Some explained the impact in terms of an increase in the supply of the baht resulting from the exodus of funds in Thailand's banks to overseas banks. Others explained in terms of a decrease in demand for the Baht. Either approach, if accurately explained, was rewarded with full marks.
Main weaknesses of answers:
- Misunderstanding of the reason(s) for the change in demand and/or supply of the baht regarding interest rates.
- Failure or partial failure to understand the link between a decrease in interest rates and the exchange rate.
- Confusion regarding the internal and external effects of a decrease in interest rates. Some students explained in terms of internal consequences e.g. effects on costs of borrowing ignoring the impact on exchange rates.
- A failure to recognise the difference between ''physical ''and ''portfolio'' investment.
