Under the Linked Exchange Rate system (LERS), the Hong Kong Dollar has been pegged to a narrow trading band between HK$7.75 and HK$7.85 per US dollar. When the Hong Kong currency hits the low end of the band, say 7.85, the city’s de-facto central bank, the Hong Kong Monetary Authority, is bound to start buying up the currency to ensure that the USD/HKD exchange rate will not fall below the weak-side Convertibility Undertaking.

The Yuan/renminbi, fell below the 'psychologically important level' of 7 to the US dollar in Aug 2019, the lowest in the onshore market since Apr 2018, leading the United States to allege that China is deliberately weakening the currency to gain trade advantages.
A weaker yuan exchange rate implies that Chinese products would be cheaper in terms of US dollars, maintaining their competitiveness in the market despite a new round of punitive tariffs imposed by the United States.
