Key Takeaways

• The political landscape in Westminster is shifting with Andy Burnham's recent by-election win.
• Oil prices are rising following the cancellation of US/Iran talks.
• Stock markets are mixed, with a notable performance in the chip sector.

1. The Battle for Westminster Begins

Andy Burnham's victory in the Makerfield by-election has set the stage for potential leadership changes within the Labour party. His move to Westminster raises questions about his leadership ambitions and the support he has from fellow MPs. Historically, political instability in the UK has led to volatility in bond and stock markets, and investors are keen to see how the bond market reacts to this latest development.

In the lead-up to the by-election, Burnham moderated his economic stance, promising to adhere to fiscal rules and Labour's manifesto commitments, which helped stabilize the bond market. However, with rising UK Gilt yields following the Bank of England meeting, the market is now testing its resilience against further political changes. The pound has weakened against the USD, dropping below the $1.32 mark, and is currently one of the weakest currencies in the G10.

2. Oil Creeps Higher

Oil prices have seen an uptick, with Brent crude surpassing $80 per barrel after the cancellation of US/Iran negotiations. Initial optimism about a potential deal has shifted to skepticism, as the agreement remains interim and does not guarantee long-term peace. The market is also monitoring traffic through the Strait of Hormuz, as any threats to this vital shipping route could significantly impact oil prices. Currently, Brent crude is up by 0.7%.

3. Stocks are Mixed, but the Chip Boom Continues

Asian stock markets reacted negatively to the news of the cancelled US/Iran talks, with the Kospi and Nikkei indices declining. European stocks are expected to open slightly lower, although the FTSE 100 may benefit from rising oil prices. In contrast, US chip stocks experienced a surge, with significant gains for companies like SanDisk, Intel, and Qualcomm, contributing to a 2.1% rise in the Nasdaq 100 index.

Despite the overall positive momentum in the tech sector, SpaceX's stock has faced a downturn, dropping 3.5% over two days, indicating a potential limit to market enthusiasm for the company following its IPO.

Conclusion

As the US markets are closed for a holiday, European indices may experience a quieter trading session. The developments in UK politics, oil prices, and the performance of tech stocks will be critical factors to watch as the week concludes.
