Simple, but not-always-correct maths. Check how much DXY rises up from its 5pm GMT +8 value and multiply that number by the 5 pm USD/MYR rate published by BNM.
Step 1
I obtain a value of 106.043 as of 5 pm yesterday Malaysia time. (In the screenshot, it's UTC, so that would be 9 am)
Also, BNM website shows a rate of 4.4540 as of 5 pm yesterday.
https://www.bnm.gov.my/exchange-rates?p_p_i...et_quotation=rmStep 2When I posted at 1:05 am this morning, DXY hits 106.50, so that is an increment of 106.50/106.043 = 4.473
Which is why I guessed it's around 4.47 when market opens today. But there is no guarantee it's exactly the case as new economic news may have changed the prospects of the currencies by 9 am today.
Moreover, DXY tracks USD against other developed market currencies like EUR, CHF, JPY. MYR is not freely-floated like those currencies and is not a developed market currency, hence there will be some discrepancy.
so it's % rise x current rate.
