The Reserve Bank of Australia's recent rate hike is a major structural shift. It has created positive policy rate spreads against the US dollar, a dynamic unseen in five years. This positive carry provides a new, fundamental support for the AUD beyond just general risk appetite or commodity prices.

The market's hawkish repricing for the Bank of Canada is likely temporary due to underlying economic slack and trade risks. In contrast, Australia's RBA is a more credible potential hiker, supported by resilient growth and higher inflation, making it a "true soft landing candidate" and a better bet for policy tightening.

The success of the current EM FX carry trade isn't driven by wide interest rate differentials, which are not historically high. Instead, the strategy is performing well because a resilient global growth environment is suppressing currency volatility, making it profitable to hold high-yielding currencies against low-yielders.

A recent global fixed income sell-off was not triggered by a single U.S. event but by a cascade of disparate actions from central banks and data releases in smaller economies like Australia, New Zealand, and Japan. This decentralized shift is an unusual dynamic for markets, leading to dollar weakness.

Contrary to conventional wisdom, a rate cut is not automatically negative for a currency. In economies like Sweden or the Eurozone, a cut can be perceived as growth-positive, thereby supporting the currency. This contrasts with situations like New Zealand, where cuts are a response to poor data and are thus currency-negative, highlighting the importance of economic context.

The initiation of the Fed's cutting cycle is the critical trigger for a weaker dollar against EM currencies, outweighing any mixed forward-looking commentary. This is because the cycle's start begins to erode the US carry advantage, a key structural factor supporting EM FX performance.

The U.S. dollar's decline is forecast to persist into H1 2026, driven by more than just policy shifts. As U.S. interest rate advantages narrow relative to the rest of the world, hedging costs for foreign investors decrease. This provides a greater incentive for investors to hedge their currency exposure, leading to increased dollar selling.

Even if US inflation remains stubbornly high, the US dollar's potential to appreciate is capped by the Federal Reserve's asymmetric reaction function. The Fed is operating under a risk management framework where it is more inclined to ease on economic weakness than to react hawkishly to firm inflation, limiting terminal rate repricing.

The Federal Reserve's dovish stance, combined with a resilient global growth outlook, creates a favorable environment for "pro-cyclical" currencies like the Australian Dollar and Norwegian Krone. This "middle of the dollar smile" scenario suggests betting on currencies sensitive to global economic momentum, not just betting against the dollar.

Instead of directly shorting the US dollar, which can be costly, traders can use the Canadian dollar (CAD) as a more profitable proxy. This approach offers a better "carry" advantage due to interest rate differentials, while still capturing the downside of a weakening USD, especially as the Bank of Canada's policy mirrors the Fed's dovishness.

Despite facing similar pressures like high inflation and slowing labor markets, the US Federal Reserve is cutting rates while European central banks remain on hold. This significant policy divergence is expected to weaken the U.S. dollar and create cross-Atlantic investment opportunities.
