06:39 AM EDT, 03/11/2025 (MT Newswires) -- The major foreign exchange rates have remained relatively stable at the start of this week in contrast to the deepening sell-off in the equity markets, noted Mitsubishi UFG.

One of the biggest movers on Monday was the Nasdaq composite index, which fell 4% and extended its decline since the high in December to almost 14%. At the same time, the VIX measure of the United States equity market volatility has risen to its highest level since early last summer when carry trades unwound abruptly after the Bank of Japan hiked rates in late July.

The heavy sell-off for US tech stocks and broad-based equity market weakness reflect building concerns over the outlook for global growth, stated MUFG. Comments from U.S. President Donald Trump stating that there's going to be a transition period for the U.S. economy and signaling that he still plans to implement further tariff hikes in the coming months have added to market concerns.

Worsening conditions for risk appetite amongst investors have reinforced demand for U.S. government bonds, putting further downward pressure on U.S. yields. It has resulted in the two-year Treasury yield falling to a fresh year-to-date low Monday of 3.83%, while the 10-year U.S. Treasury yield fell back below support from the 200-day moving average, which comes in at just above 4.20%.

U.S. rate market participants have moved to price in more Federal Reserve rate cuts in the coming years in response to building growth concerns, pointed out the bank. However, the spill-overs into the foreign exchange markets from the deepening sell-off in the U.S. equity market have been limited so far.

The commodity currencies of the Australian, New Zealand and Canadian dollars have all underperformed modestly at the start of this week, while the Norwegian krone, yen and euro have outperformed, added MUFG. If the period of risk aversion continues to intensify it remains to be seen whether the US dollar will weaken further alongside the decline in U.S. yields and U.S. equities which has been the relationship that has been in place since the start of this year, or whether the US dollar begins to drive more support from a pick-up in safe haven demand.

Heightened U.S. policy uncertainty created by President Trump is raising doubts over the US dollar's safe haven role alongside the unwinding of popular U.S. tech trades.

The euro has benefitted at the start of Tuesday's European trading session from reports that the Green party in Germany is now ready to negotiate with CDU leader Friedrich Merz over his plans to significantly boost government spending on defense and infrastructure and are hoping to reach an agreement by the end of this week. The Green party's co-head Franziska Brantner told Bloomberg News that "of course we are ready to negotiate" and added that "the situation is dire in Ukraine and we really need Europe to step up its defence spending."

While the Greens won't be part of the next coalition government in Germany, their support is needed to pass legislation through parliament to unlock funds for a significant increase in government spending. The Greens have proposed raising the threshold for defense spending exemptions to 1.5% of the gross domestic product compared with Prime Minister-in-waiting Merz's plans to set it at 1.0%.

Market participants remain optimistic that a deal will be reached with the Greens to pass legislation before the newly elected Bundestag convenes by March 25 at the latest, added MUFG. The prospect of a significant fiscal support is helping to ease concerns over downside risks to the growth outlook for Europe.
