Every 5 years, central banks complete reviews to Trade Weight Indices and annual reviews to include or eliminate currencies based on trade. Normally, the threshold is 1% trade to inclusion or elimination decisions based on annual reviews. What changes yearly are the weights in the index assigned to each currency. The 5 year overhaul is a complete revamp to a trade weight index so to change the base period by addition of 5 years and to include or eliminate certain currencies.

The BOE maintain 2 indices, a Broad and Narrow to include major and minor trade partners in line with the Fed’s Nominal and Other Trade Partner Index.

The trading methodology is a depreciating currency in the index such as AUD will trade higher as AUD dropped against its major trade partners. But that’s the old method. My way is view as many currencies against the main currency whether its in the index or not because it covers many more currencies not in the index.

Best index construction is Laspeyres and use equal weights rather than as assignment to weights based on major or minor trade partners. A better performance to the index will be seen with specifics to percent movements and eyeball view which currencies moved most or least.

The RBNZ Trade Weight index includes the major currencies and: KRW, CNY, MYR, IDR, THB, SGD, INR and PHP, Philippines Peso.


NZD/CNY is oversold but not to any degree to immediately jump on a trade yet NZD against 11 currencies and many not in the RBNZ Trade weight index, is massively oversold to extremes. Not only is NZD/USD oversold against the majors but deeply oversold to EM currencies. This concept offers a broader view and many more trades while the TWI lacks to effective oversold and overbought readings.
