This could be an important week for UK markets. Economists at ING analyze Pound Sterling (GBP) outlook ahead of the Spring Budget.

Hopes of delivering pre-election tax cuts are likely to be met by funding constraints, even though we estimate the headroom has increased from £13bn to £18bn thanks to slightly lower market rates compared to November’s Autumn Statement.
