A late EUR/USD fifth wave tested by the Bund-Treasury gap

A chart impulse still needs a regime

A currency impulse can look orderly on a price chart and still sit against the capital-flow backdrop that this workflow used as context. The archive kept an Elliott count on EUR/USD, then asked whether the 10-year German Bund versus 10-year US Treasury yield differential still favored that count.

The point of the pairing is not to decorate a wave label with another market. It is to decide whether a single EUR/USD advance is still inside a supportive relative-return regime, or whether the chart is running ahead of the yield gap that was treated as the leading intermarket input.

Turnover mix and the long-horizon driver

In the supplied market-structure snapshot, speculative transactions were 93.7% of daily currency turnover, capital-flow-related transactions 4.6%, and goods-and-services-related transactions 2.1%. Capital flow was still treated as the dominant long-horizon fundamental driver of currency rates.

Trade flow was given limited influence because a large share of global trade is invoiced in dollars. In that framing, the smaller capital-flow share of turnover is not a reason to ignore it. It is the channel through which cross-border investment seeks the higher relative return.

The Bund-Treasury gap as a capital-flow input

The 10-year German Bund versus 10-year US Treasury yield differential was presented as a leading intermarket input for EUR/USD. The premise was that capital gravitates toward the relatively higher-yielding government-bond market.

Used this way, the gap is a relative-return signal, not a second price chart of the same pair. A firmer Bund-side advantage was treated as support for the euro. A move toward Treasury advantage was treated as a reason to question euro strength.

When the gap and the rate moved together, and when they did not

From July 1995 to June 1999 the Bund-Treasury differential moved from 62 basis points in favor of the Bund to minus 159 basis points, while EUR/USD declined from 1.4171 to 1.0535. After June 1999 the yield gap improved from -1.59% to -0.507% by November 2000, but EUR/USD continued to a low of 0.8378, a lag of about 16 months before the pair turned higher.

From November 2000 to November 2002 the two series rose together: the yield differential from -0.507% to +0.608% and EUR/USD from 0.8378 to 1.0098. The joint rise is the easy case. The earlier lag is the harder one: an improving gap did not produce an immediate turn in the exchange rate.

A lead-adjusted reading of the same spread

A 12-month lead-adjusted Bund-Treasury differential was reported as 94% correlated with the dollar-Deutschemark rate before euro introduction and 73% correlated with EUR/USD afterward. The looser fit was attributed to the euro representing many countries rather than Germany alone.

That lead-adjusted spread is how the archive inspected historical alignment. It does not remove the lag after June 1999, and it does not make the German Bund a complete stand-in for every euro-area borrower. It does explain why the same gap was still used as context after the euro replaced the mark.

The Elliott count from the 2000 low

An Elliott wave count on EUR/USD placed wave 1 from 0.8378 in November 2000 to about 0.9516 in January 2001, wave 2 near 0.8708 in February 2002 or alternatively 0.8473 in July 2001, wave 3 near 1.2818 in January 2004, and wave 4 near 1.1887 in May 2004. The subsequent advance was labeled a possible fifth wave of the rally from the 2000 low.

That Elliott fifth wave was described as the most speculative phase. The label matters here because the turnover snapshot already assigned most daily currency activity to speculative transactions. A late-stage impulse is exactly where a standalone chart count is easiest to over-trust.

Late-2004 divergence against a possible fifth wave

By 3 December 2004 the yield differential had fallen from about -0.05% on 17 October 2004 to -0.57%, while EUR/USD had risen since 4 September. That stretch was treated as a lack of yield-gap support for the euro.

This is intermarket divergence in the sense used here: the exchange rate moved opposite the direction implied by the yield gap. The fifth-wave label was then used to interpret the late-2004 EUR/USD rally against the deteriorating Bund-Treasury spread. Price was still advancing. The capital-flow input was not.
