Record of discussion of meeting of Exchange Fund Advisory Committee Currency Board Sub-Committee held on April 30
The following is issued on behalf of the Hong Kong Monetary Authority:
(Approved for Issue by the Exchange Fund Advisory Committee by circulation)
Report on Currency Board Operations (25 December, 2024 - 16 April, 2025)
------------------------------------------------------------------------------------
The Currency Board Sub-Committee (Sub-Committee) noted that the Hong Kong dollar (HKD) traded within a range of 7.7555 - 7.7927 against the US dollar (USD) during the review period. The HKD exchange rate moderated in early January 2025 as liquidity tightness subsided at the end of 2024 and global markets reacted to US tariff announcements, but strengthened in mid-February 2025, supported by strong performance of the local stock market amid Mainland China's recent advancements in artificial intelligence and net inflows from the Southbound Stock Connect. In early April, in response to further US tariffs, the HKD strengthened further as long USD carry trades unwound amid a risk-off sentiment and southbound inflows continued. HKD interbank rates (HIBORs) continued to track the USD rates while shorter-tenor rates were also being affected by local supply and demand. Short-term HIBORs tightened briefly near the year-end but softened thereafter as funding demand faded. The Convertibility Undertakings were not triggered during the review period and the Aggregate Balance was stable at around HK$45 billion. No abnormality was noted in the usage of the Discount Window. Overall, the HKD exchange and interbank markets continued to trade in a smooth and orderly manner.
The Sub-Committee noted that the Monetary Base increased to HK$1,980.99 billion at the end of the review period. In accordance with the Currency Board principles, all changes in the Monetary Base had been fully matched by changes in foreign reserves.
The Report on Currency Board Operations for the review period is at Annex.
Monitoring of Risks and Vulnerabilities
------------------------------------------
The Sub-Committee noted that downside growth risks to the global economy had intensified following the US announcement of imposing reciprocal tariffs that exceeded market expectations. In response, global financial markets had gyrated, although they continued to operate smoothly with no sign of widespread funding stress. While the postponement of reciprocal tariffs had offered some reprieve for export-reliant Asian economies which generally faced higher rates, the prospect of tariffs being implemented further down the road still posed significant growth headwinds.
The Sub-Committee noted that in Mainland China, the economy entered 2025 amid some green shoots and improved equity market sentiment. In particular, at the "two sessions" in March, the authorities sent strong pro-growth signals, including prioritising consumption and strengthening fiscal support. From April onwards, the Mainland economic outlook faced stiffer external headwinds due to the US reciprocal tariffs. It was expected that Mainland China would place increasing emphasis on supporting consumption.
The Sub-Committee noted that in Hong Kong, downside risks to the growth outlook heightened following the imposition of the US reciprocal tariffs. Yet, several factors might help alleviate some of the impact, including the Mainland's pro-growth policies and its advancement in artificial intelligence, the prospective US rate cuts expected by the markets, and the ongoing recovery of inbound tourism. Meanwhile, housing market transactions gained momentum in March following the Government's adjustment in stamp duties for lower-value properties, although market sentiment turned conservative in early April amid the global financial market volatility. The commercial real estate markets remained subdued, especially in the office segment.
A Study on "Discount Window Stigma"
-------------------------------------------
The Sub-Committee noted a paper that examined the usage of the Hong Kong Monetary Authority's (HKMA)Discount Window and the associated "stigma effect" by banks over time. The results showed that the Discount Window was tapped more frequently and the associated stigma diminished in the current period of tight liquidity, compared with the previous period of tight liquidity in 2018 - 2020. This trend coincided with the HKMA's proactive communication efforts with banks to alleviate concerns about the "stigma effect" during recent periods.
Update on chikungunya fever
The Centre for Health Protection (CHP) of the Department of Health announced that, as of 5pm today (January 4), no new cases of chikungunya fever (CF) had been recorded.
Latest surveillance data
------------------------------
Hong Kong has recorded a total of 82 confirmed CF cases last year. Among them, 11 were local cases, and the rest were imported cases.
Since the beginning of 2025, and as of December 10, 2025, a total of 502 264 CF cases and 186 CF-related deaths have been reported in over 40 countries/territories. Cases have been reported in the Americas, Africa, Asia, and Europe. Although the northern hemisphere has entered the winter season, temperatures in subtropical and some temperate regions remain elevated due to climate change, creating favourable conditions for mosquito breeding. In addition, CF outbreaks continue to occur in many countries worldwide. The risk of imported cases persists. Members of the public should check the situation of the destinations before travelling abroad, especially when travelling to Southeast Asian countries.
Government's comprehensive follow-up actions
-----------------------------------------------------
Given that some local cases of CF have visited the Tsing Yi Nature Trails or the surrounding area in November last year, the trails are currently closed until further notice. Relevant government departments continue to conduct large-scale mosquito control and prevention efforts along the trails, and the CHP appeals to the public not to enter the area in order to reduce the risk of contracting CF and to avoid exposure to chemicals or interfering with the mosquito control operations. Since the confirmation on December 10, 2025, of a case involving a person who had visited the Tsing Yi Nature Trails on November 30, 2025, no further local cases have been recorded to date. The CHP continues to urge individuals who have recently hiked along the Tsing Yi Nature Trails to seek medical attention as soon as possible if they develop relevant symptoms and to call the enquiry hotline (Tel: 2125 2373), which operates from 9am to 6pm.
The Food and Environmental Hygiene Department (FEHD) has been continuously conducting intensive fogging operations to eliminate adult mosquitoes along the Tsing Yi Nature Trails and the surrounding area. At suitable locations, large ultra-low volume foggers have been deployed, and a robot dog is being put on trial to enhance operational effectiveness. The FEHD has also set up new mosquito trapping devices, cleared discarded containers and garbage that could cause stagnant water, and applied larvicide oil or larvicides in areas with stagnant water that cannot be removed immediately. The FEHD has been collaborating with the Kwai Tsing District Office, the Lands Department and the Drainage Services Department to strengthen efforts in eliminating potential mosquito breeding sites along the Tsing Yi Nature Trails. Pamphlets have been distributed to hikers in the area, urging citizens to be vigilant against mosquito infestations and take personal protective measures. The FEHD has also held meetings of the interdepartmental task forces on anti-mosquito work across districts to discuss the latest developments regarding the situation and plan accordingly to co-ordinate relevant departments and stakeholders in strengthening mosquito prevention and control measures in areas under their purview.
Continuously strengthening prevention and control
---------------------------------------------------------
The FEHD and relevant departments have comprehensively enhanced the mosquito control operations in Hong Kong since July last year, and this has continued. Among these, the FEHD has conducted vector investigations and targeted mosquito control operations against the imported and local cases. In light of the local case, the FEHD has immediately conducted follow-up actions, including:
carrying out intensive fogging in scrubby areas within a 250-metre radius of the relevant locations to kill adult mosquitoes;
carrying out inspections of the locations, removing stagnant water, applying insecticides and disposing of abandoned water containers every week with a view to preventing mosquito breeding; and
enhancing public education efforts through organising health talks, setting up mobile education stations, and distributing publicity leaflets.
The abovementioned measures will be continued. Furthermore, the Government will further enhance the mosquito control efforts in addition to the existing measures.
Preventive measures to be taken by the public
----------------------------------------------------
Members of the public should use DEET-containing insect repellents or other effective active ingredients properly to prevent mosquito bites, but the following precautions should be taken when using them:
read the label instructions carefully first;
apply right before entering an area with a risk of mosquito bites;
apply on exposed skin and clothing;
use DEET of up to 30 per cent for pregnant women and up to 10 per cent for children (for children who travel to countries or areas where mosquito-borne diseases are endemic or epidemic and where exposure is likely, those aged 2 months or above can use DEET-containing insect repellents with a DEET concentration of up to 30 per cent);
apply sunscreen first, then insect repellent;
reapply only when needed and follow the instructions; and
in addition to DEET, there are other insect repellents available on the market containing different active ingredients, such as IR3535 and picaridin. When using any insect repellent, the public should follow the usage instructions and precautions on the product label.
The FEHD also appeals to members of the public to continue to stay alert and work together to carry out mosquito prevention and control measures early, including inspecting their homes and surroundings to remove potential breeding grounds, changing water in vases and scrubbing their inner surfaces, removing water in saucers under potted plants at least once a week, and properly disposing of containers such as empty cans and lunch boxes. The FEHD also advises members of the public and property management agencies to keep drains free of blockage and level all defective ground surfaces to prevent the accumulation of water. They should also scrub all drains and surface sewers with an alkaline detergent at least once a week to remove any mosquito eggs.
