Understanding the 28 Major Forex Pairs: A Strategic Liquidity Framework

By way of the State Administration of Foreign Exchange's latest release, China's foreign exchange market cleared RMB 152.21 trillion in turnover across the first half of the year, with RMB 28 trillion traded in June alone — a liquidity backdrop that, in our view, is reshaping how desks frame major pair positioning into the back half of 2026. As traders parse these flows alongside the Traders Union's freshly compiled taxonomy of the 28 major forex pairs and a dollar probing critical resistance ahead of the FOMC, the cross-currents across the pair complex deserve careful unwinding rather than reflexive reaction.

The Dollar's Pre-FOMC Squeeze

According to FOREX.com's technical outlook, the greenback is testing major resistance into the Federal Reserve's announcement, and we treat this as the pivot that will dictate directional conviction across the majors. Against the yen specifically, Moomoo's Tokyo foreign exchange coverage places the pair around the mid-163 handle as investors booked profits ahead of the FOMC statement on the 29th — a zone we are monitoring closely, given its implications for carry behavior, Japanese exporter repatriation flows, and the broader risk sentiment that tends to bleed into commodity-linked pairs. The convergence of these signals suggests that any hawkish pivot, or conversely any dovish surprise, will propagate through the 28-pair grid with notable speed, because liquidity is no longer siloed by session.

Reframing the 28-Pair Universe

The Traders Union's complete list is best understood, in our reading, not as 28 independent instruments but as a highly interconnected liquidity network where capital flows redistribute across cross-pairs whenever the majors reprice. We tend to organize the set into tiers — the anchor majors that anchor rate-differential arbitrage, the crosses that translate that differential into regional volatility, and the emerging market exposures that absorb dollar liquidity shifts most acutely. The SAFE data underscores why this architecture matters now: with RMB 28 trillion concentrated into a single month, Asian session turnover has become structural rather than residual, meaning FOMC-driven repricing will register in CNH-linked pairs with the same velocity as it does in the G10 crosses.

Levels and Catalysts We Are Tracking

We are watching three pressure points into and beyond the FOMC print. First, the dollar's capacity to hold above the resistance zone flagged in the FOREX.com outlook, because a failure there would unwind long-USD positioning across EUR/USD and the commodity bloc simultaneously. Second, the durability of the mid-163 area on USD/JPY without a shift in BOJ rhetoric, since that level has historically invited verbal intervention and would compress realized vol if breached. Third, the broader capital migration underway across alternative digital asset markets — including metaverse gaming and GameFi ecosystems, which continue to absorb retail liquidity that once cycled through exotic crosses. For our purposes, the takeaway is straightforward: yield differentials, central bank tone, and session-specific liquidity absorption are the three currents that will determine which of the 28 pairs rewards positioning over the coming weeks.
